32 Cool Science Experiments for Kids (that are Fun AND Easy!)

Do you ever want to do science experiments at home with your kids, but you’re not quite sure what to do? Not just any old kitchen science experiment will do – you want something cooler than vinegar + bicarb soda! But, you also want something simple and easy to do – because no-one wants a huge mess from their kids doing crazy science experiments at home!

We understand, and that’s why the writing team here at STEM Geek has put our heads together to come up with the most awesome at-home science experiments for kids! As science enthusiasts and educators, we also wanted to make sure that these are genuine science learning opportunities. So not only are they captivating for the kids, but we also emphasize what questions can be asked as kids explore and apply the scientific method! Plus, we’ve arranged them according to how much time they take: up to 1 hour, 1 to several hours, and long-term.

Science Experiments at Home that take Less than 1 Hour

1. tie-dye milk.

Sounds delicious, right? You’re not actually drinking it, but instead watching science magic happens when you combine dish soap with milk and food coloring. This is a very pretty experiment that draws the focus and mind into what’s happening on the plate, and all because of a little chemistry with everyday items. Well, food dye may not be an everyday item, but it might be after your kids get a hold of this!

So, what’s going on here, scientifically-speaking? Milk is made up of two major ingredients: water and fat. When you add a little dish soap, it bonds with the fat in the milk so strongly that it literally pushes the food coloring and water away from the cotton ball. On a microscopic level, the dish soap is wandering around the milk, which causes the colors to swirl and swirl.

Questions to ask beforehand:

• Before knowing what will happen to the food coloring, ask the kids what they think will happen when dish soap mixes with milk.
• Since the major catalyst is fat in the milk, what would happen if you used other types of milk: Skim milk, soy milk, coconut milk?

You’ll need:

• Round cake pan or plate with high edges
• Cotton ball (some tutorials show cotton swabs)
• Dish detergent
• Different colors of food dye (three or four should do)

Procedure/Instructions:

• Fill the pan halfway with milk.
• Drip one color of food dye in one section of the plate away from the center. Four to five drops works and later you can play around with more or less. Do the same for the rest of the colors around the plate.
• Soak the cotton ball in dish detergent, and when you’re ready for action, place the cotton ball into the center of the pan.
• Watch the colors racing around, creating a psychedelic tie-dye effect!
• You can add more cotton balls throughout the dish to see more action.
• If some food coloring hugs the wall of the plate, take a cotton swab dipped in dish detergent and place it into the food coloring. It will move away!

2. Saturn’s Glowing Rings

I don’t know about you, but I love everything about space. This experiment shows you how Saturn’s rings are made of rocks and ice chunks even though they look so smooth in pictures. You’ll also see why there are big gaps in the rings. Younger kids take delight in using a flashlight and sprinkling powder, while older kids can get more specific with questions about Saturn and how the rocks and ice stay in orbit.

• Do Saturn’s rings give off their own light?
• Why are some rocks and ice chunks more lit up than others?
• Compare the results of light sprinkles to thicker sprinkles.
• Strong flashlight
• Powder (flour, baby powder, etc) in a shaker
• Very dark room
• Darken a room and set the flashlight on the edge of a table or counter, pointing it at a blank wall. Lay the newspaper on the floor between the flashlight and the wall.
• Turn on the flashlight and notice where the light comes from the flashlight and where it hits the wall. You should only see the light from these two places and not from the space between them. This shows you that the light travels through the air without being seen until it hits the wall. The light represents the sun’s light.
• Now to see how Saturn’s rings glow: Hold the powder shaker and sprinkle some powder over the beam of light where you know the light is traveling. You’ll notice the powder lights up and sparkles in the beam of light. The powder shows in glowing clumps, just like in Saturn’s rings.

3. Breaking Down Colors

We all know that the fun, vibrant colors we see in our lives are created by mixing the basic red, yellow, and blue. In this experiment, you and your child will learn which colors make up those fun shades they have in their art supplies. This also teaches some basic chemistry and uses materials you already have at home. It can be done very simply and expanded to create a large-scale investigation if you love it.

• Which colors separate out first?
• Is the same order for each test?
• Which colors make up the original shade?
• Do the different types of color (pen, pencil, paint) separate in the same way or differently?
• Are some separated in a shorter space are the colors the same mixture?
• Coffee filters
• Color sources (markers, colored pencils, paint, etc.)
• A plain pencil
• To complete this experiment, cut the coffee filters into strips, mark one end with a line the same distance from the bottom on each strip.
• Color in each strip (between the bottom and line) with your colors, and write at the top what the color and source are (e.g., purple marker).
• Place each strip in a glass and help it to stand up by folding the top over a pencil (a chopstick, table knife, or any long narrow object will also work) so that it stands up in the glass.
• Fill the glass up to the top of your colored block, and wait. The water will move up the filter, and the colors will separate out as it goes.
• Remove the strip once the water gets near the top of the strip to stop the experiment. 

To make this a true experiment, we recommend testing multiple colors and using markers, colored pencils, and paint (as some starting examples). You could test the same colors from each type of art supply to investigate whether they all use the same mix of basic colors to create the same end product.

This post has a nice full description of the methods if you need more detail.

4. Water Xylophone

This simple experiment will teach your child about sound and pitch using glasses, water, and something to act as a mallet. Don’t let the simplicity deceive you, there are a lot of ways to experiment and learn through this process, and it also brings in an element of music that makes it interesting and engaging.

• Do you think more water makes the sound higher or lower in pitch?
• How do you think the shape or size of the glass will affect the sound?
• How should we arrange the glasses to play a simple song?
• Do you think this will work with a plastic cup, why or why not?
• Some glasses
• Something wood to act as a mallet (we recommend wood so you don’t break the glasses!)
• A great way to start is with glasses that are the same size, shape, and material, and filling them with different amounts of water.
• Have your child use the mallet to test how the amount of water affects the sound.
• From there, it’s a really simple extension to use different sized and shaped glasses (or any glass vessel like jars and bowls) to experiment with how the shape, size, and amount of water in the glass affect the tone. 

To take this one further and really bring in the musical component, you and your child could work out a simple song and create the right tones to play it. If you or your child are musical, you could get very elaborate and creative (try googling harry potter or star wars theme songs on glasses, there are so many options that I couldn’t even choose one)!

5. Ultimate Bottle Flipping

Ah, bottle flipping. The fad that kids can’t get enough of, but parents are well and truly over. The constant thud of semi-filled water bottles being tossed (and hopefully landing upright) is guaranteed to send parents around the twist!

If you can stand it for a bit longer though, there’s a lot of STEM knowledge to be gained in this bottle flipping experiment. As we know, the aim of bottle flipping is to flip a partially filled water bottle underhand and get it to land upright.

In this experiment, kids will learn the importance of observing a result multiple times before changing a variable (the amount of water in the bottle).

• How much water should you put in the bottle?
• What is the ideal amount of liquid to get the perfect flip?
• What should be the ideal amount of water?
• Was their prediction correct?
• Why do they think the amount of water affects the chances of landing the bottle?
• A plastic water bottle
• Measuring jug
• Paper to record results
• Get the kids to start by flipping their bottle with no water in it at all. Kidspot recommends flipping it 50 times for each step, but you could do less if you need to.
• Try it again with 50ml of water.
• Keep adding more water until the bottle is full.

If they’re keen, you could try other types or sizes of bottles, or even try different liquids to see if that affects the results!

6. Rainbow in a Jar

This simple science experiment is not only very visually appealing, but it’s also a great way to learn about the density of liquids. Warning though, this one could get messy so make sure kids are in some old clothes and you might want to take it outside! I like this experiment because you’ll probably have most of the materials in your kitchen already!

• Which liquids they think will be heaviest?
• Which ones will be lightest?
• Why do they think that?
• A glass jar
• Food coloring
• Various liquids like honey, corn syrup, dishwashing liquid, olive oil, rubbing alcohol and water.
• Use the food coloring to make all your liquids a different color. A dropper comes in handy here, but if you don’t have one you can manage without.
• Slowly add each liquid to the jar (pouring into the middle of the jar is best).
• Soon, you’ll have different layers of colored liquid forming your very own rainbow in a jar.

You might even get them to draw a diagram of what they think the jar will look like at the end. They can compare this with the experiment results to see if their prediction was correct.

It might also help to talk to your kids first about what density is and how materials are all made of different amounts of molecules. The more molecules a liquid has, the heavier it will be. Playdough to Plato demonstrates a great way of introducing this concept using marbles. 

7. Write Your Own Secret Messages! 

We love science experiments that are made up primarily of supplies that you likely already have in your home.

• Why do you think this will work?
• Which liquid do you think will make the best secret message?
• Why do people write secret messages?
• Juice (eg. Lemon)
• Lamp (or anything else that can be used as a heat source)
• In order to complete this experiment, you’ll need to gather all of your supplies along with a piece of paper, some q-tips, and a lamp or other item that you can use as a heat source.
• Next, you’ll mix your lemon juice with a slight amount of water. 
• Using your q-tip, use the mixture you’ve created to begin writing your message. 
• Allow it to dry. 
• Once dry, apply heat to it in order to get your message to appear.

Extend this project by attempting to write with a juice and water mixture, a milk and water mixture, or any other variation of the liquids we listed as necessary supplies!

8. Create Your Own Butterfly

Your little ones will love practicing their color mixing by creating their very own coffee filter butterflies. Hang them in the windows of your home to spread some cheer and to watch the sun flow through their beautiful wings! 

• What colors can mix together to make other colors?
• How do butterflies fly?
• What do you think will happen when we add water to the markers?
• Water spray bottle
• Allow your child to draw on the coffee filter to their heart’s content.
• Spray it with water and allow the colors to mix together.
• Allow it to dry thoroughly.
• Once dry, fold it like a fan and then clip it in the middle.

Ta-da, you’ve created a beautiful butterfly! 

9. Make A Duck Call

Give your family an excuse to head outdoors by allowing your children to craft their own duck calls. Test them out at a local pond and see if you can get the ducks to come closer to you for a healthy veggie snack! 

• Do you think ducks will be able to hear us with this?
• What other materials do you think could make this noise?
• How is what we have created similar to a duck’s beak?
• Plastic straw
• Push down on the straw to flatten one end and then cut the flattened end into a point.
• Flatten out your straw and then blow into it.
• Feel free to experiment with different amounts of flattening and different point shapes to see how you can adjust the sound.
• When finished, take your duck call into the wild to test it out.

10. Make Ivory Soap Boats

Did you ever carve items out of soap at camp when you were a child? Give your child the same opportunity. Soap can be carved using safe items, like plastic knives. 

• Why are we able to carve soap so easily?
• Do you think our boats float?
• Why do you think they float or sink?
• Carving tools (for kids)
• Allow your child to express their creative side by carving their boat out of soap. 
• Once they have finished carving it, allow them to test them out in the bathtub. . Extend their learning by discussing density with them–the soap floats because it is less dense than the water.

11. Make Your Own Quicksand 

As John Mullaney famously said, “I thought quicksand would be a much bigger problem in my adult life than it would have turned out.” For some reason, quicksand permeates children’s adventure stories – and their imaginations! 

• Where can we find quicksand in real life?
• How do you think quicksand works?
• What do you think we will need to make our own quicksand?
• Cornflower (one cup)
• Water (half cup)
• A container
• To make your quicksand, you’ll need to mix the cornflour and water. 
• Be sure to stir slowly in order to demonstrate – if you stir too quickly, it will become hard and you won’t be able to see it function the way it should!

12. Make Your Own Lava Lamp

We’ve tried this one in our classrooms, and trust us, our kids go wild year after year. Kids love making something that they can use as home decoration, and they love how easy it is to show new people – this is the experiment that lives on and on! 

• How do you think density is involved in this experiment?
• Why don’t the water and oil mix?
• Why can’t we shake our lava lamps?
• Clear Plastic Bottle
• Vegetable Oil
• Food Coloring
• Alka-Seltzer
• Pour water into the plastic bottle until it is approximately one quarter full. 
• Then pour vegetable oil in until the bottle is almost completely filled. 
• Allow some time for the oil and water to separate. 
• It is important that your children do not shake the bottle in this step. It will extend the experiment for no other reason than you waiting for the bubbles to dissipate. 
• Add as much food coloring as your child deems fit and then drop a piece of Alka-seltzer tablet into the bottle for the lava lamp fun to begin.

13. Guess the Smell

This one will take a little more prep work, but it’s a great touchstone for your children to begin discussing one of their five senses: the sense of smell! 

• What are examples of times we use our sense of smell?
• What other senses do we have?
• If you could only use one sense for the rest of your life, which one?
• Plastic Cups
• Smells (eg. coffee, cinnamon, vanilla, lemon juice)
• Place a variety of common smells in small plastic cups. We like to use coffee, cinnamon, vanilla, and lemon juice. 
• Pour these in and place tin foil securely over the top of the cup. 
• Poke small holes in the top of the foil. 
• Secure the foil with tape (on the sides, not over the holes). 
• Allow your children to guess the smells and record their findings on paper.

Home Science Experiments that take 1 to Several Hours

14. mangrove bioshield  .

Ecologists and conservationists are pushing for more regulations in building and saving mangrove forests around coastal areas. The reason is represented in this STEM activity. The trees act as a mangrove BioShield (bio = life, shield = protection), showing how natural obstacles can prevent critical damage from marine natural disasters such as tsunamis.

The mangrove BioShield can be for older elementary kids through to high school. Obviously, the younger they are, the more parent involvement. This experiment is done twice to show the effects of having and not having a BioShield. The first part uses little to no trees, and the second uses a forest of trees and rocks.

• What will happen in a tsunami if the village is without a BioShield? And the village with a BioShield?
• Would a BioShield help with hurricanes?
• Would you want to encourage people to save manatee forests if they are beneficial?
• Medium to large clear, plastic container
• Newspaper – wad into balls, then cover half of the bottom container – this help to keep the ground sturdy
• Mud – cover the newspaper and press it in to form a slope down to the empty side of the container. The top side should be flattened for the cardboard houses, then it slopes down into the empty half of the container.
• Cardboard houses (use the bottoms of milk cartons for the house and popsicle sticks for the roofs, place houses on the mud towards the top of the high slope
• Model trees or leafy stems from plants – Different amounts for activity 1 and activity 2
• Several small rocks
• Cardboard – long enough to fit across the container and tall enough to hold it from out of the water
• Water – enough to go halfway up the slope

A tsunami without the mangrove forest – insert only one or two trees down the slope. Place the cardboard piece into the water end of the container and move back and forth to create waves. Notice how easy it is for the water to destroy the village you’ve created.

Repeat the process of constructing the village, but this time insert a lot of trees down the slope to where the water meets the mud. They need to be deeply rooted like mangroves, and I’ve found that aquarium plants work well for this reason. Place the rocks within the mangrove forest and in front of the trees. Add a little bit more water. Insert the cardboard again and move it back and forth to create waves.  

15. A Greater Crater

When you look at the night sky and see the moon, one of the first things you notice is its craters. The moon is completely covered in them, and some are so large we can see them from Earth. Meteorites often make the craters that we see when they hit the surface, but it makes us wonder why some craters are so much bigger than others.

This experiment will help you to investigate one of the main reasons why craters come in different sizes.

• What causes craters?
• How big do the meteorites have to be to make a crater?
• What is it about the meteorite that causes the size of the crater?
• Paper to record your results
• Flat floor surface for the experiment, large enough for the newspaper to cover
• Shallow metal pan at least 2 inches deep
• Flour to fill 2 inches of the pan
• ¼ cup hot chocolate powder
• Mesh strainer or flour sifter
• Large marble (and others of varying sizes if comparing results)
• Metric ruler
• Tongs or long tweezers
• Pour the flour into the pan until it reaches 2 inches. Place the pan on top of the newspaper on a level surface.
• Sift a layer of hot chocolate powder over the flour (this is so you can better see the rays and other features of the craters).
• You will be dropping your marble from three different heights, then comparing the sizes of the craters. Measure the diameter (side to side) of the marble and record this on your paper as Marble 1. Hypothesize how large the crater will be and write that next to the diameter of Marble 1.
• Stand next to your pan and hold the marble at knee height above the flour. Drop the marble (do not throw it, just let it fall from your fingers) into the flour and study the shape of the crater. Look for a rim around the crater or any rays coming from the edges.
• Measure across the widest part of your crater, from rim to rim and record on your data sheet as Marble 1 – Knee Height – Width or something similar. You can also draw a picture of your results.
• Very gently use the tongs or long tweezers to remove the marble without destroying the crater.
• Repeat this procedure from waist height, shoulder height, top of head height. Make sure you aim in different parts of the flour so you don’t land on top of another crater. Record all of your results as the different heights you’re using.
• Compare your results.
• You can try again with a different sized marble as “Marble 2” to compare those results with each height as done with Marble 1.

Perhaps now, you’ll look at the moon a little differently!

16. Rube Goldberg Chain Reaction Machine

We’ve all seen them, some pretty far-out there chain reaction machines to complete simple tasks, usually in movies. But they are real , and are becoming even more popular now that we’re all stuck at home for a while. This is a fun way to explore physics with stuff you have at home.

Ask your child to decide what the end goal is (e.g. get the ball into the cup), and ask them to think about creative ways to make it get there. Working together, you can start with small pieces of a circuit to find out how your ball reacts to the set-up, and grow it from there. You can even refer to this video for more ideas:

• What will happen when the ball bounces off of this wall?
• How will these dominoes change the speed of the ball?
• What can we use to make sure that the ball goes in the direction we want it to at this point?
• What should we put here to get the best bounce? 
• Paper towel
• Toilet paper tubes
• Fixed objects like walls or furniture
• Any other toys and materials that can be used to build your circuit

To make this a true experiment, it needs to include more than a one-off demonstration, and there are a lot of ways to accomplish this.

• Set up parallel courses and use different sized or weighted balls to go through the circuit.
• Set up one elaborate circuit and use different objects one at a time.
• Set up circuits in different ways to see how different set-ups affect your end goal.

Another experimental component is the process used to create a circuit that reaches your end goal ( like this video about getting the ball into the cup, but you could come up with lots of other endpoints!). Along the way, you and your child get a lot of time to learn about momentum, velocity, friction, energy transfer, and interference (e.g., the cat). 

17. Melting

This is a simple and fun experiment that can be set up in a short time and then fill-up your day with observations and new experiments. Using only things you already have at home, you can set-up an engaging experiment with your kids!

Ice melts at different rates depending on a variety of factors including temperature, pressure, and if there are impurities (think salt, sugar, dirt) in the ice or touching the ice. There is a lot of opportunities to get creative and do the experiment in multiple ways, keeping your kids engaged and developing their investigative, experimental, and critical thinking skills.

• Which ice melts the fastest, slowest, and if they have any guesses about why?
• What other ice-melting experiments they think would be fun: Using different temperature liquids? Using different amounts of ice? Different sized cups?
• Lots of ice
• Several matching cups (i.e., they are the same size, shape, and color)
• Measuring cups
• A variety of liquids for the test
• Paper for writing down observations
• Measure the same amount of ice and place it in each cup.
• M easure equal amounts of each liquid and place them in the cups: try to complete this part quickly so that the ice in each cup is in liquid for as close the same amount of time as possible.
• Set up your cups in a place that is easy for your child to watch and observe.
• Ask them to check in at regular intervals (every 15 minutes, every hour) and record or talk to you about their observations.

Other potential experimental examples:

• Using different liquids to test if they affect melting time;
• Using the same liquid and placing ice in different locations to test what conditions throughout your home affect melting;
• Test if different amounts of ice melt at different rates;
• Test if different kinds of cups change melting time.

There are endless possibilities for you to come up with new ways to complete these simple experiments. You get the idea. Explore more!

18. Breathing Leaves

Science experiments don’t get much more simple than this one!  It’s effective though and kids will enjoy watching their leaf ‘breathe’. Learning about plant science is often tricky because it can seem a bit abstract. This experiment allows kids to see the process of plants making oxygen right before their eyes!

A question to ask beforehand:

• What do you think will happen if we leave it for a few hours?
• A fresh leaf from a tree
• A bowl of water
• Pluck a fresh leaf from a tree and place it in a bowl of water.
• Use a rock to weigh it down and leave the experiment out in the sun.
• Have your kids predict what they think they will see when they come back in a few hours (they can write their prediction down or draw a diagram if that’s more their style).
• After a few hours, your kids will see lots of tiny little bubbles on the edge of the leaf and in the glass bowl of water (use a magnifying glass to get a closer look if you have one).

So, what’s happening here? Leaves take in carbon dioxide and convert it to oxygen during photosynthesis. The bubbles you can see are the leaf releasing the oxygen it’s created. You could explain to your kids how trees and plants make the oxygen we need to breathe. Kids Fun Science explains this experiment in more detail and suggests taking it further by leaving the plant for a longer period of time (do you see more or fewer bubbles?) or placing a leaf in a dark area to see what difference that makes!

19. How Does Sunscreen Work?

If there’s one thing I know, it’s that kids hate wearing sunscreen! Trying to get it on them is like wrestling a crocodile. Maybe if they knew how sunscreen worked they’d understand how important it is to wear it when they’re out in the sun (and be slightly more cooperative when we’re lathering it over their little faces). This is a simple experiment that shows kids the difference wearing sunscreen will make to their skin.

• What do they observe when they come back?
• Why do they think one side faded and the other not?
• A piece of colored cardboard (a dark color would be best)
• Your usual bottle of sunscreen
• Have your kids smear the sunscreen over one part of the cardboard and leave the other part clear.
• Kids can then predict what they think will happen when they return to the experiment after a few hours.
• Talk to them about how the sun’s UV radiation is absorbed by the sunscreen so it can’t get through to damage the cardboard.

You could even take it further by trying different kinds of sunscreen or leaving your cardboard out during different times of the day.

20. Make A Rubber Egg

Imagine a world in which eggs can be used like bouncy balls. Well, with a couple of home supplies and a little bit of science, you can live in that world. Your child will be dazzled as they remove eggshells from eggs while leaving the insides intact. 

• Is vinegar an acid or a base?
• Is there another substance that could do this?
• Simply leave the egg in the vinegar for a few hours and wait to see what happens. Because of the transformative nature of this experiment, it lends itself to science journaling. 
• Consider having your kiddos draw before and after pictures of the eggs in order to track their journeys. 

21. Flying Tea Bags

Nothing will get your kids’ attention faster than telling them that you are going to spend some time creating something that will fly. However, because this experiment will involve fire, please ensure that you select a time in which you will be able to provide ample adult supervision. 

• How do we stay safe with fire?
• How do we make sure we don’t damage the surface we are working on?
• Why do you think the tea bag will fly?
• Single Serving Tea Bags
• A Small Bowl
• A Non-Flammable Work Surface
• First, open the tea bags and unfold them. 
• Empty the leaves from the bag. 
• Stand the tea bags up on your surface and light the top of each bag on fire. 

As they begin to burn, they will float into the sky! 

22. Make Wax Paper Lanterns

Your children will love the chance to display their fantastic art skills by creating these paper lanterns. If you want to add a culture lesson, have your children research German’s St. Martin’s Day and learn about why children parade through the streets with lanterns. We promise there’s a good moral story involved here! 

• When could we use lanterns?
• What safety considerations do we need to use in this project?
• Why can we see the light through the wax paper?
• Popsicle Sticks
• To begin, tear a ten-inch piece of wax paper off of the roll and cut it in half. 
• After that, fold each piece in half. 
• Allow your child to color their image on top of the wax paper. (This is a great place for an impromptu lesson in color mixing). 
• Fold the wax paper and iron it (consider something in between the crayon mess and the iron you use on your clothes). 
• Finally, glue the craft sticks into squares, add the wax paper, and turn it into a cube.

Voila, you’ve created your own lantern!

23. Create an Insect Habitat

Alright, this one isn’t for the faint of heart. Draw up your courage and send your child into the backyard to collect all of the creepy crawlies they’d like to.

Now you have a home for them. Better yet, you can keep your child entertained for hours as they track the growth of their bug friends.

• What do bugs need to survive?
• What do bugs eat?
• What is the difference between a need and a want?
• Imagination
• Find something that you’re willing to sacrifice to the bugs in order to create a habitat for them – we recommend a shadowbox so that your child can see inside, but a cardboard box will do just fine as well. 
• Ensure that there is breathing room for the bugs. 
• Create a habitat with sticks, bark, small rocks, dried leaves, and whatever else you can find.
• If you’re willing to hang onto the habitat long enough, use it as an opportunity to talk about decomposition as the bugs begin to break down the twigs.

Long-Term Science Experiments at Home

24. crystal kingdom.

This is the oldest trick in the book, but it’s popular because it’s so effective, fun, and has great results. The only drawback to most crystal-growing recipes is that they take ages to grow, and to be quite honest this one is no exception. In fact, these crystals will take several days to grow but the end result is worth it. The reason is that this experiment involves growing a whole landscape of beautifully colored salt and bluing crystals. Here’s a video for visual reference: 

A few things to keep in mind: Allow for plenty of air circulation, preferably inside rather than outside. Ammonia is not necessary but does help in the process.

• What will happen when you add ammonia?
• Why does more salt and less liquid create faster crystallization?
• What part does the bluing solution have in crystal growing?

(Answers can be found here )

• Two bottles of bluing solution
• Large tray/cookie sheets with sides
• Measuring cup
• Liquid watercolors
• Eye droppers
• Cut sponges into large pieces. Spread them out on the tray.
• Measure out 1 cup of each of salt, water, and bluing and then gently mix together.
• Evenly coat or sprinkle the mix over the sponges.
• Add 1 cup of ammonia to the sponges.
• Coat an extra 1 cup of salt on to the sponges.
• By now you’ll see some crystals growing . Sprinkle the magic mix again: 1 cup each of salt, water, and bluing. You can pour the ingredients onto the tray instead of on top of the crystals to keep them from breaking. Don’t worry, more will grow!
• Take an eyedropper, and drop a tablespoon of each liquid watercolor (undiluted) in different patterns over the sponges and crystals.
• Take note of your garden and what the crystal formations look like. You can make a sketch in your notebook as a before and after. Ask questions and observe!
• Observe how the crystals are bigger than before, and notice the colors aren’t as vibrant. Compare the differences in shapes, sizes, and colors.
• If you want more crystals to grow, add a little more water, bluing, and salt.

25. Blow up a Balloon with Yeast

We are surrounded by science in action, but sometimes it is really difficult to see what is happening, especially when it is on a small-scale. When we make bread, yeast ‘eats’ the sugars in the food and creates CO2, giving bread its airy texture. This experiment lets you both visualize what happens when yeast consumes sugar and is a great set-up for an experiment that can be observed throughout the day.

Depending on your supplies and time, you could start with a demonstration and use that to think of other tests, or you could set up several parallel tests at the same time.

• How quickly does the balloon filled with air?
• When does it stop filling (at some point the yeast will run out of food and will stop making gas)?
• Does the starting temperature affect the experiment?
• Does the balloon fill faster in different places in your home (try especially for different air-temperatures, you could include an outside location)?
• Some balloons
• Blow up the balloon a few times before starting so that it’s loosened up a bit.
• Fill the bottle with about 1 inch of warm water (heat is required to activate the yeast, but you could experiment with different temperatures), add the yeast and swirl to dissolve.
• Add the sugar and swirl more.
• Place the balloon over the opening to the bottle and wait. You should expect to see the balloon begin to inflate after around 20 minutes.
• Continue checking and observing how much the balloon inflates throughout the day.

More example experimental setups include:

• Do different temperatures – either with the water you start with or the air the yeast lives in – affect how quickly the balloon blows-up?
• Does using 2x the yeast result in a balloon that is 2x bigger, or blows-up 2x faster?
• Do different types of sugar (e.g., white sugar, honey, syrup, flour) affect how quickly the balloon blows up or how big it gets?

A sk your child to think of new experiments (you could prompt with some of the examples above, or ideas from this post ). 

26. Seed Germination

A really simple but fun multi-day experiment is germinating seeds under different conditions. This means finding some quick-sprouting seeds such as beans and putting them in different conditions to see how that affects germination (sprouting leaves and roots) and growth.

I love using seed experiments because they are inexpensive, simple, and leave a ton of room for creating your own unique experiment.

• Which seed will sprout fastest?
• Seeds (Beans, radishes, squashes, and many flowers sprout quickly from large seeds, making them good choices.)
• Small pots or paper cups
• Potting soil
• Cloth or paper towel
• Somewhere with good light
• To get started, you’ll need some seeds – feel free to choose something you already have, if you’re a gardener you might have some seeds ready for the coming season and could spare a few – or find something online or at your local nursery.
• Use small pots or paper cups and fill each with your growth material (we recommend a minimum of 3 for a useful comparison).
• Fill one with potting soil, one with sand, and one with a cloth or paper towel.
• Place them somewhere with good light, and add water.
• Ask your child to predict which seed will sprout fastest, and make observations every day. If possible, make them around the same time each day.
• Once you see growth, you can ask your child what they think caused any differences, and you can use that as a jumping-off point for more experiments

Additionally, you could:

• Use one type of seed and different types of growth media: soil, paper towel, gravel, sand, water, etc.
• You could use different seeds (beans, flowers, grass, herbs) and grow them under the same conditions (soil, water, sun exposure) to see how different plants grow differently.
• You could see how different light conditions (by a window, in the basement, in a bright room away from a window, etc.) affect germination.

You could also extend each experiment by simply continuing to grow each seed to learn whether the different germination time affects long-term growth (you may want to re-pot everything in the soil for this to be effective, depending on the specifics of your initial experiment).

27. Colored Celery

It’s hard to imagine plants having little capillaries inside them that transport water and nutrients, but this experiment shows that in action. It’s easy to set up, but you’ll have to wait at least a day to see some results. Your kids will be able to see how transpiration takes place and plants absorb water from the soil all the way up into their leaves.

• A few stalks of celery (celery works best for this because it’s a bit more visible, but you could also use flower stems)
• Different food coloring
• Place each stalk in a cup of colored water and make your predictions about what will happen.
• After a day or so you’ll see the celery leaves becoming the color of the water they’re standing in.
• Have your kids describe their observations (they can write down what they see or draw it if they prefer).
• If you look at the base of the stem you’ll also see tiny little holes that the colored water is traveling through.

When you’re done with the experiment, make sure you snap the celery and look inside – you should be able to see the capillaries in action. For more ideas, Little Bins for Little Hands has got some great hints and tips for this experiment.

28. Moldy Bread

This experiment is an oldie, but a goodie! Kids love looking at disgusting things and this one will certainly come up with the goods. Not only will kids learn about how mold grows, but they might also take on some lessons about the importance of washing their hands!

You might want to check out the results of this experiment at Science Alert before you start to see if your stomach is up to it.

• A few slices of bread
• Some ziplock bags
• Sticky little hands. 
• Get a few slices of bread and lay them out on your kitchen bench.
• Have your kids touch one piece of bread with dirty, unwashed hands.
• They can wash their hands with soap and water and touch another slice, then do the same using hand sanitizer.
• Leave one piece of bread untouched.
• Place them all in clear, labeled ziplock bags and predict which one will grow the most mold.
• Leave your bread slices for at least a week (it may take a bit longer, depending on the conditions where you live) and get the kids to record their observations.

You can also try wiping your bread slices on other surfaces to see what moldy results you get (their laptop or tablet is a great place to start)!

29. Sprouting Beans

Give your household a real survivalist feel by beginning an indoor garden. We recommend planting your beans in a clear cup so that your children can be privy to all of the processes during the plant’s journey.

• How does a plant grow?
• What does germination mean?
• What is in season to grow in our area now?
• Unprocessed Beans
• If you’d like your child to see every step of the process, consider placing the beans inside of a damp paper towel inside of a ziplock. 
• You can wait, see the germinated seed together, and then plant it inside of a small cup.
• Once inside the cup, watch it grow.

Extend your work by planting various beans and altering the growth conditions in order see what makes your beans grow best! 

30. Begin Composting

Begin your “go green” resolutions by teaching your child the value of composting! Best of all, once the science experiment is done, your family will have a recycling process that will last your entire lifetimes. 

• Why is composting important?
• How else can our household go green?
• Why do we need a foundation layer for compost?
• Compost Bin
• Organic Material
• First, create a compost bin. You can purchase one or build one out of wood. 
• To begin your composting, you’ll need even amounts of brown materials (think shredded paper, dryer lint, etc.) and green materials (think fruit and vegetable waste, lawn clippings, etc.). 
• If you’re really feeling fancy, throw some earthworms in there.

For days to come, your family will be able to discuss what can and cannot be broken down by the decomposers inside of the compost bin. Never-ending science! 

31. Turn Grapes Into Raisins

Your kids may or may not eat raising – but we can guarantee you, they’ve likely never considered the option of creating their own! 

• What other snacks can we make with science?
• Should we ever eat our experiments?
• How does this work?
• For this experiment, you’ll need grapes. (Really, that’s it!) 

Leave your grapes somewhere where they will not be disturbed and use this as an opportunity for your children to journal the changes in the grapes from day to day. Believe it or not, this type of sequential journaling is a valuable literacy skill! 

32. DIY Science Experiment

The best science experiment your child can engage in is the one they create themselves! Begin brainstorming a list of questions and let the world be their oyster as they plan and carry out their own experiments. Some of our favorite brainstorming questions, from Scholastic’s Science-Fair Project Guide, are listed below:

• What is the effect of toothpaste brand on teeth-cleaning power?
• What brand of trash bag can withstand the most weight before ripping?
• How does the type of material affect how long a shirt takes to dry?

This super easy experiment involves mixing equal parts oil and water and adding a drop of food coloring to see what happens. Kids will love watching the food coloring make it through the oil. You will love how easy it is to set up and clean up!

• Several drinking glasses
• vegetable oil
• liquid food coloring
• a toothpick (if you have it)

18. Exploring Colors With Baking Soda / Vinegar

I n this science activity for kids of all ages, your little scientists will create a chemical reaction, explore color mixing, AND create colorful artwork. Triple win!

• Tray (A baking sheet will do)
• Baking soda
• White vinegar
• Ice Cube Trays or other containers to hold the colored vinegar
• Pipettes or eye droppers
• Liquid watercolors or food coloring

19. Water Cycle In A Bag

This is one of the best science experiments to teach your kids about the water cycle, and it’s so easy to do! They’ll watch the water cycle in a bag play out right before their eyes.

• Zip lock bag
• permanent marker
• blue food coloring

20. Tie-Dye

Who would have thought that everyone’s favorite t-shirt pattern is actually a great science lesson, too? As your child dyes the shirt, they’ll be observing water solubility and absorption in real time. The dyes are fiber-reactive, which means that a chemical reaction takes places between the dye molecules and fabric molecules so that they actually become one. The dye bonds with the fabric and actually becomes a part of it.  

• White T-shirt or pillowcase
• Buckets or bins filled with water
• Rubberbands
• Plastic gloves

21. Static Electricity Hair

Want to provide your kids with (literally) hair-raising good time? It’s super simple to teach your kids about static electricity with this easy, no-mess science activity.

• an inflated balloon
• a piece of cloth

Rub the surface of the balloon with the cloth for at least40 seconds. Then, hold the balloon a short distance above your head and watch your hair stick to it!

What’s Happening:

T he balloon gains electrons from the cloth and becomes negatively-charged when you rub it together. Then, when the balloon touches you hair, it attracts your hair, which is positively charged.

22. What’s That Mystery Object?

The process of using your sense of touch is very important to the scientific method. In this experiment, you’ll use your sense of touch to see how many different textures you can recognize.

• A grown-up or friend to help
• A blindfold
• A “feely” bag that you can’t see through

Small objects from around the house that have different textures, such as: a plastic bag, a water bottle, a banana, a piece of paper, a cell phone, a rubber ball, a cotton ball, a tooth brush, a washcloth, etc. Try to find objects of different materials like velvet, wool, cotton, leather, metal objects, wooden spoons or toys, pieces of aluminum foil, and other interesting objects and textures.

First, put on your blindfold. The next step is to have a grown up or friend put a mystery object in the bag for you to fell. Can you guess what each object is?

23. Sugar Water Rainbows

This science experiment is especially meant for older kids, but it can me modified for kids of all ages. Your kids will love this colorful experience about density and buoyancy, and all you need are some common household ingredients.

• food colorings (preferably in rainbow colors including red, orange, yellow, green, blue, purple)
• a clear straw
• salt or sugar

First, fill each of the cups with the same amount of water.

Next, add the food coloring, one color in each cup, preferably in rainbow order.

Line the cups up next to each other.

In the first cup, do not add any sugar at all.

In the second cup, add one tablespoon of sugar.

In the third cup, add two tablespoon of sugar.

In the fourth cup, add three tablepoons of sugar, and so on.

Stir each mixture until all the sugar is dissolved in each glass.

The next step is to make a sugar rainbow by placing the end of the straw in the first cup (the cup with no sugar), only about a half of an inch.

Cover the top of the straw with your thumb before lifting it out of the water so that the water does not fall out of the straw.

Now dip the straw into the second cup (1 tablespoon sugar). This time, insert it deeper so that the end is one inch below the water level. In one quick move, release the thumb and recap again. Now you should have two layers of color.

Keep dipping the straw into each solution from the one with the least sugar to the one with five tablespoons of sugar. Each time, the straw is inserted half an inch deeper.

What’s happening?

Density is the amount of substance (mass) within the volume occupied by the object. If two cups have the same amount of water (i.e. same volume), the one with more sugar is denser than the one with less sugar.

Buoyancy is determined by relative density. The solution with less density floats above the solution with higher density. That is why the color don’t mix.

Sugary water has higher density than plain water. The solution with more sugar has higher density than the one with less sugar. If you have inserted the straw in the solutions from the least sugar to the most sugar, then the color don’t mix and you have a sugar water rainbow.

24. Painted Nature

In this activity, kids will be closely observing natural phenomena, looking for signs of life and growth, and using their senses to experience natural materials. These skills are extremely important scientific foundations.

First, have your child search for natural objects in nature. Fill a bag with interesting sticks, leaves, rocks, twigs, pebbles, and anything else you can find.

Next, bring them into the “classroom” or home to closely observe and paint them.

As you paint, you can discuss the natural colors and features of these objects: What is their texture? What do they notice about each object?

My kids love “melty crayons”. They can’t get enough of them. Gather several rocks and heat them up in the oven. Then, carefully draw on them with crayons. The heat of the rock will melt the crayon wax and the it will go on like paint.

25. Magnet Dump

This activity is a great introductory magnet activity, and for younger kids, they’ll be practicing skills of classifying and sorting.

First, dump out a selection of metal objects onto the table.

Next, ask your kids to help you “clean up” by using the magnets to pick up different objects and sort them into containers.

Discuss which objects are attracted to a magnet and which are not. What patterns do they notice? What other objects would they like to try?

26. Magnet Magic

• Clear plastic box (look in your recycling bin)
• Pipe cleaners

This super-easy experiment is a really fun way to teach your child about magnets in a colorful, magical way, and it only requires simple materials from around the house. 

First, cut up several pipe cleaners and place them in a clear plastic box. The box does not need to be fancy, just see-through.

For your first time through this demonstration, have your child take a magnet and touch it against the surface of the plastic box. They’ll find that the pipe cleaners are lifted up and move with the magnet!

What’s Happening?

Magnets attract certain types of metal. The pipe cleaners have a thin strip of metal, so the magnet is able to attract those pieces and pull it around the box.

Extension:  Next time, think of what other objects could you place in the box? What objects do you predict the magnet could move around?

27. LEGO Boats

This experiements present a great opportunity to get kids thinking about engineering and design.

First, challenge your kids to build their own boat out of LEGO bricks. For an added challenge, only give them a certain number of pieces.

Once everyone has finished building, put the boats to the test in a tub of water.

Add pennies a few at a time to see how many each boat can hold.

Talk to your kids about how weight and design matter. Reflect on good designs and help them understand why they worked well.

28. DIY Parachute

You can learn about gravity by making a DIY parachute for a light-weight toy. The parachute is easily made from materials around your house, and you can experiment with different strategies and objects.

• Plastic Bag (i.e. grocery bag)
• Yard/String

First, use the scissors to remove the handles from the plastic bag. Next, poke four holes around the plastic bag so that they are the same distance apart and on opposite sides of the bags.

Then, cut four holes into the rim of the paper cut.

You’ll also need to cut four pieces of yarn, 10-12 inches long. Thread one piece of yarn through the hole in the plastic cup and tie the yarn to the cup with a knot. Repeat with all four strands of yarn in the remaining holes.

Next, thread the other end of the pieces of yarn through the hole in the plastic bag and tie a knot. 

Finally, personalize and decorate your cup with stickers, paint, crayons or markers.

Now it’s time to find a toy that is going to take a ride in your parachute. Launch your parachute into the air and see what happens!

Experiment with putting different objects into the paper cup and see how it affects the parachute’s effectiveness. Does the parachute flight time increase or decrease?

You can also try creating the parachute with different materials to replace the paper bag, such as a paper towel or napkin, and see how that affects the performance.

29. Magic Milk Experiment

• Full Fat Milk
• Dawn Dish Soap
• Cotton Swabs

First, pour the milk in a small baking dish until the bottom is covered. Next, fill the milk with drops of food coloring. Glitter is optional!

Then, pour some dishwashing soap into a bowl, and dip your cotton swap tip into the dish soap to coat it. Then, gently touch your cotton swab to the milk and watch what happens!

Milk is composed of minerals, proteins, and fats, which are easy to change. When you add the dish soap to the milk, the soap molecules try to attach to the fat molecules in the milk.

When everything stops moving, you can see where all the fat molecules are.

30. Steel Wool & Vinegar Reaction

This experiment will make abstract concepts like “chemical reaction” and “rusting” become more clear and concrete.

• two beakers
• something to cover the beaker (paper or a lid)
• Thermometer

First, place the steel wool in a beaker. Then, pour vinegar onto the steel wool and let it soak for about a minute.

After a minute or so, take the steel wool out and shake off any excess vinegar.

Next, wrap the steel wool around the base of the thermometer and then place them both in the other beaker.

Then, cover the beaker with paper or a lid. It’s important that you keep the heat in.

You’ll want to make sure that you can still read the temperature on the thermometer. It’s a great idea to poke a hole if possible through the covering so that the thermometer can fit through it, and you can easily read the temperature.

Make a note of the initial temperature, and observe it for about five minutes.

You will see that the temperature on the thermometer gradually rises, and the beaker will likely get foggy. When you soaked the steel wool in vinegar, it removed the protective coating on the steel wool, allowing the iron in the steel to rust.

Rusting is actually a chemical reaction between iron and oxygen (or oxidation). This is the chemical reaction that creates heat, thereby increasing the temperature of the beaker and on the thermometer. This is an examples of an exothermic reaction (a chemical reaction that releases energy in the form of heat).

31. Corn Syrup Viscosity Experiment

This experiment could not be simpler, and it’s the perfect tool for teaching kids of any age about viscosity.

-Corn Syrup

-2 glass containers (one should be smaller than the other)

-cupcake pan or 3 small bowls

-Food coloring

First, fill the larger glass container 1/2 to 3/4 full with corn syrup. Then, add the small glass container to the center. Careful! The corn syrup will rise a bit when you do this.

Next, Use a cupcake pan or 3 small bowls and put in a small amount of corn syrup. Mix each one with a food coloring of your choice. You should have three separate colors of corn syrup.

Then, put some colored corn syrup in the dropper, insert the dropper into the clear corn syrup and add the coloring in different places. Do that for each color as many times as you wish.

Now, you can turn the smaller glass jar while holding the outer glass still. The colored syrup will start to spread a bit. Now, switch direction and turn the small glass jar back to its original place. The colored dots return right back to their original form.

Corn syrup has a viscosity that is 5,000 times that of water, so they don’t mix in the same way.

32. Homemade Play Dough

This is a classic DIY project, and kids of all ages will love it.

• 3 cups of flour
• 1.5 cups of salt
• 6 teaspoons cream of tartar
• 3 tablespoons of oil
• 3 cups of water

33. Melting Snowballs

This is another acid and base experiment, and it’s fun on a couple different levels!

First, form snowballs by adding water to the baking soda. You’ll need about a 1/3 cup per snowball.

Then, place them in the freezer for 15 minutes.

Finally, pour drop of vinegar on the snowballs and watch them sizzle and melt.

Variations:

You can also make a snowman and do the same thing!

34. Paper Airplanes

Overview: There’s no better way for kids to learn about aerodynamics than by making a paper airplane. Wow Fold, a paper airplane website, offers dozens of paper airplane designs and easy to follow instructions.

35. Flying Ping Pong

Your kids will love this flying ping pong trick, and there are only two things you need.

First, make sure your hair dryer is on a cool setting. Then, hold the ping pong above the nozzle and turn on the air. When you let the ping pong go, it should float! Next, try it on different settings. Try to see how far you can tilt your hair dryer before the ball drops.

36. Magical Balloon

Your kids won’t believe their eyes when you push a needle through a balloon and it doesn’t pop!

• Scotch tape

First, blow up your balloon. Next, take two pieces of scotch tape and make an X on your balloon. Then, with parental supervision, push a needle through the middle of your X.

Leave the needle in and see how long it take for your balloon to finally pop!

The tape slows down the process of the hole in the balloon widening, so it takes longer for the balloon to pop.

37. What’s That Mystery Smell?

Kids of all ages can recognize a lot of different smells, and the process of using your senses is very important to the scientific method.

In this experiment, you’ll use your senses to see how many different smells you can recognize.

• Small, lidded containers that you can’t see through
• Smelly things from around the house such as bananas, an orange peel, lemons, a cotton ball soaked in perfume, chopped onion, coffee (or a used coffee filter!), rose or flower petals, pencil shavings, vanilla, vinegar, ginger, etc.

First, have a grown up put the smelly items in the containers.

Then, write a number on the side of each container.

The next step is to put your blindfold on and have them help you smell each object.

Write down what you think is inside of each container.

Finally, check your guesses! How many did you guess correctly?

38. Wacky Spoon

This is more of a science trick than an experiment, but it’s super easy to do at home!

Kitchen Spoon

Look at your reflection in a large spoon. It will be upside down!

A regular mirror is flat and sends your reflection straight back into your eyes. The rounded spoon bounces your reflection back at different angles and turns your reflection upside down. 

39. Floating Eggs

This experiment will show your child how things float differently in fresh water and salt water.

• 2 tall drinking glasses

First, fill one glass with water. Then, fill another glass with water and add 8 tablespoons of salt. Mix it up.

Next, place an egg in both glasses. One will float and the other will sink.

Adding salt to the water increases the water’s density which causes the egg to float.

40. Jumping Pepper

This simple experiment will demonstrate static electricity right before your eyes.

Place a tablespoon of pepper on a plate. Then, run a hair comb through your hair. While still holding on the comb, hold the comb over the plate and watch the pepper jump!

The plastic comb builds up a negative charge as it moves through you hair. The pepper has a positive charge, so it jumps!

Try it with other spices and powders.

41. Walking on Eggs

Your kids will be astonished to see that they can actually walk on eggs without breaking them!

• 6 dozen eggs in their cartons-Drop cloth / newspaper

Lay down your drop cloth in case the experiment doesn’t work as expected!

Place the open egg cartons next to each other. Take off your sock and shoes and gently step onto the eggs keeping your feet flat. Then bring up your other foot and carefully walk across the eggs.

Your foot is big enough that your weight spreads evenly out across the eggs, keeping them from breaking.

You can also demonstrate this concept with a heavy book. 

42. Disappearing Reflection

Make your reflection vanish! All you need is aluminum foil.

-Aluminum Foil

-Scissors (optional)

Rip off a large piece of aluminum foil (ten inches should do) and take a look at your reflection. Then, crumple up the aluminum foil. Next, Carefully flatten it back out. Finally, look for your reflection. It’s nowhere to be found!

When the aluminum foil is smooth, light reflect off of in in straight lines, which enables you to see your reflection. But once you crumple the foil, it has a wrinkled surface that sends your reflection in all different direction, causing it to disappear.  

43. Defy Gravity!

When you turn over a cup of water, you expect the water to spill and fall. But not always!

Clear plastic cup

Playing card or notecard

First, fill your clear glass about 3/4 of the way with water.

Next press your playing card or notecard gently on the top of your glass to completely cover the top. Gently rotate the cup upside down. After a few moments, remove the card. The water will stay in place!

Try it again, adding something that will float in the water. Repeat the steps, and see what happens!

45. Water Fireworks

This totally safe fireworks experiment will be a hit around the Fourth of July or any time!

Tall water glass

Small water glass

First, fill up your all water glass almost all the way with water. In the small glass, pour two tablespoons of oil. Add 2 drops of food coloring to it and mix it around with a fork until the food coloring is broken up into smaller specks.

Then, pour the oil mixture into the water and see the firework expand!

What’s happening:

Food coloring dissolves in water but not oil, causing it to go different directions.

Try two colors! Try a different size glass!

46. Bird Feeder Fun

In this simple science project, you’ll learn where birds like to have their meals.

-Pipe Cleaner

Place cheerios on a pipe clean and make a simple circle. Place it out for the birds to eat.

To experiment, place different bird feeders in different places and see if it makes a difference for how much gets eaten.

You could also make your bird feeder into different shapes to see how the birds prefer it.

47. Rain Gauge

It’s super simple to make a rain gauge from a soda bottle and track your area’s rain water!

Soda Bottle

X-acto knife (with parental supervision)

Cut the top off of a soda bottle and invert the top so that the rain water funnels into the bottle. You may want to secure it with duct tape. Next, place it outside in a spot where it can collect rain water.You’ll want to secure it so it doesn’t fall over. Then, begin measuring the rain water each day!

48. Magic Leak Proof Bag

-Ziplock Back

-Very Sharp Pencils

Fill your bag up halfway with water. Carefully poke the pencil through the bag and out the other side. (Don’t push the pencil all the way through so that it comes out the other side!)

The plastic bag’s molecules form easily around the smooth sides of the pencil forming a seal.

49. Paper Cup Tower

Similar to the “walking on Egg” experiment listed above, this activity will wow your children as they discover they won’t crush the paper cups by standing on them!

8 paper cups

First, set the paper cups on the grounds, spaced evenly. Next, place the cardboard on top of them. Then, try to stand on it and see what happens. Can you make another level?

50. Rubber Band Guitar

Tap into your musical side and explore sound with this simple rubber band guitar.

Paper or plastic cup

Rubber bands

First, wrap your rubber bands of different sizes around the cup so that the rubber bands act as strings over the hole of the cup. Then, pinch the sides of them together as best you can and tap them around the sides of the cup. See what sounds they make, and experiments with rubber bands of various sizes to see what sounds they make!

Sat / act prep online guides and tips, 37 cool science experiments for kids to do at home.

General Education

Are you looking for cool science experiments for kids at home or for class? We've got you covered! We've compiled a list of 37 of the best science experiments for kids that cover areas of science ranging from outer space to dinosaurs to chemical reactions. By doing these easy science experiments, kids will make their own blubber and see how polar bears stay warm, make a rain cloud in a jar to observe how weather changes, create a potato battery that'll really power a lightbulb, and more.

Below are 37 of the best science projects for kids to try. For each one we include a description of the experiment, which area(s) of science it teaches kids about, how difficult it is (easy/medium/hard), how messy it is (low/medium/high), and the materials you need to do the project. Note that experiments labelled "hard" are definitely still doable; they just require more materials or time than most of these other science experiments for kids.

#1: Insect Hotels

• Teaches Kids About: Zoology
• Difficulty Level: Medium
• Messiness Level: Medium

Insect hotels can be as simple (just a few sticks wrapped in a bundle) or as elaborate as you'd like, and they're a great way for kids to get creative making the hotel and then get rewarded by seeing who has moved into the home they built. After creating a hotel with hiding places for bugs, place it outside (near a garden is often a good spot), wait a few days, then check it to see who has occupied the "rooms." You can also use a bug ID book or app to try and identify the visitors.

• Materials Needed
• Shadow box or other box with multiple compartments
• Hot glue gun with glue
• Sticks, bark, small rocks, dried leaves, bits of yarn/wool, etc.

#2: DIY Lava Lamp

• Teaches Kids About: Chemical reactions
• Difficulty Level: Easy

In this quick and fun science experiment, kids will mix water, oil, food coloring, and antacid tablets to create their own (temporary) lava lamp . Oil and water don't mix easily, and the antacid tablets will cause the oil to form little globules that are dyed by the food coloring. Just add the ingredients together and you'll end up with a homemade lava lamp!

• Vegetable oil
• Food coloring
• Antacid tablets

#3: Magnetic Slime

• Teaches Kids About: Magnets
• Messiness Level: High (The slime is black and will slightly dye your fingers when you play with it, but it washes off easily.)

A step up from silly putty and Play-Doh, magnetic slime is fun to play with but also teaches kids about magnets and how they attract and repel each other. Some of the ingredients you aren't likely to have around the house, but they can all be purchased online. After mixing the ingredients together, you can use the neodymium magnet (regular magnets won't be strong enough) to make the magnetic slime move without touching it!

• Liquid starch
• Adhesive glue
• Iron oxide powder
• Neodymium (rare earth) magnet

#4: Baking Soda Volcanoes

• Teaches Kids About: Chemical reactions, earth science
• Difficulty Level: Easy-medium
• Messiness Level: High

Baking soda volcanoes are one of the classic science projects for kids, and they're also one of the most popular. It's hard to top the excitement of a volcano erupting inside your home. This experiment can also be as simple or in-depth as you like. For the eruption, all you need is baking soda and vinegar (dishwashing detergent adds some extra power to the eruption), but you can make the "volcano" as elaborate and lifelike as you wish.

• Baking soda
• Dishwashing detergent
• Large mason jar or soda bottle
• Playdough or aluminum foil to make the "volcano"
• Additional items to place around the volcano (optional)
• Food coloring (optional)

#5: Tornado in a Jar

• Teaches Kids About: Weather
• Messiness Level: Low

This is one of the quick and easy and science experiments for kids to teach them about weather. It only takes about five minutes and a few materials to set up, but once you have it ready you and your kids can create your own miniature tornado whose vortex you can see and the strength of which you can change depending on how quickly you swirl the jar.

• Glitter (optional)

#6: Colored Celery Experiment

• Teaches Kids About: Plants

This celery science experiment is another classic science experiment that parents and teachers like because it's easy to do and gives kids a great visual understanding of how transpiration works and how plants get water and nutrients. Just place celery stalks in cups of colored water, wait at least a day, and you'll see the celery leaves take on the color of the water. This happens because celery stalks (like other plants) contain small capillaries that they use to transport water and nutrients throughout the plant.

• Celery stalks (can also use white flowers or pale-colored cabbage)

#7: Rain Cloud in a Jar

This experiment teaches kids about weather and lets them learn how clouds form by making their own rain cloud . This is definitely a science project that requires adult supervision since it uses boiling water as one of the ingredients, but once you pour the water into a glass jar, the experiment is fast and easy, and you'll be rewarded with a little cloud forming in the jar due to condensation.

• Glass jar with a lid
• Boiling water
• Aerosol hairspray

#8: Edible Rock Candy

• Teaches Kids About: Crystal formation

It takes about a week for the crystals of this rock candy experiment to form, but once they have you'll be able to eat the results! After creating a sugar solution, you'll fill jars with it and dangle strings in them that'll slowly become covered with the crystals. This experiment involves heating and pouring boiling water, so adult supervision is necessary, once that step is complete, even very young kids will be excited to watch crystals slowly form.

• Large saucepan
• Clothespins
• String or small skewers
• Candy flavoring (optional)

#9: Water Xylophone

• Teaches Kids About: Sound waves

With just some basic materials you can create your own musical instrument to teach kids about sound waves. In this water xylophone experiment , you'll fill glass jars with varying levels of water. Once they're all lined up, kids can hit the sides with wooden sticks and see how the itch differs depending on how much water is in the jar (more water=lower pitch, less water=higher pitch). This is because sound waves travel differently depending on how full the jars are with water.

• Wooden sticks/skewers

#10: Blood Model in a Jar

• Teaches Kids About: Human biology

This blood model experiment is a great way to get kids to visual what their blood looks like and how complicated it really is. Each ingredient represents a different component of blood (plasma, platelets, red blood cells, etc.), so you just add a certain amount of each to the jar, swirl it around a bit, and you have a model of what your blood looks like.

• Empty jar or bottle
• Red cinnamon candies
• Marshmallows or dry white lima beans
• White sprinkles

#11: Potato Battery

• Teaches Kids About: Electricity
• Difficulty Level: Hard

Did you know that a simple potato can produce enough energy to keep a light bulb lit for over a month? You can create a simple potato battery to show kids. There are kits that provide all the necessary materials and how to set it up, but if you don't purchase one of these it can be a bit trickier to gather everything you need and assemble it correctly. Once it's set though, you'll have your own farm grown battery!

• Fresh potato
• Galvanized nail
• Copper coin

#12: Homemade Pulley

• Teaches Kids About: Simple machines

This science activity requires some materials you may not already have, but once you've gotten them, the homemade pulley takes only a few minutes to set up, and you can leave the pulley up for your kids to play with all year round. This pulley is best set up outside, but can also be done indoors.

• Clothesline
• 2 clothesline pulleys

#13: Light Refraction

• Teaches Kids About: Light

This light refraction experiment takes only a few minutes to set up and uses basic materials, but it's a great way to show kids how light travels. You'll draw two arrows on a sticky note, stick it to the wall, then fill a clear water bottle with water. As you move the water bottle in front of the arrows, the arrows will appear to change the direction they're pointing. This is because of the refraction that occurs when light passes through materials like water and plastic.

• Sticky note
• Transparent water bottle

#14: Nature Journaling

• Teaches Kids About: Ecology, scientific observation

A nature journal is a great way to encourage kids to be creative and really pay attention to what's going on around them. All you need is a blank journal (you can buy one or make your own) along with something to write with. Then just go outside and encourage your children to write or draw what they notice. This could include descriptions of animals they see, tracings of leaves, a drawing of a beautiful flower, etc. Encourage your kids to ask questions about what they observe (Why do birds need to build nests? Why is this flower so brightly colored?) and explain to them that scientists collect research by doing exactly what they're doing now.

• Blank journal or notebook
• Pens/pencils/crayons/markers
• Tape or glue for adding items to the journal

#15: DIY Solar Oven

• Teaches Kids About: Solar energy

This homemade solar oven definitely requires some adult help to set up, but after it's ready you'll have your own mini oven that uses energy from the sun to make s'mores or melt cheese on pizza. While the food is cooking, you can explain to kids how the oven uses the sun's rays to heat the food.

• Aluminum foil
• Knife or box cutter
• Permanent marker
• Plastic cling wrap
• Black construction paper

#16: Animal Blubber Simulation

• Teaches Kids About: Ecology, zoology

If your kids are curious about how animals like polar bears and seals stay warm in polar climates, you can go beyond just explaining it to them; you can actually have them make some of their own blubber and test it out. After you've filled up a large bowl with ice water and let it sit for a few minutes to get really cold, have your kids dip a bare hand in and see how many seconds they can last before their hand gets too cold. Next, coat one of their fingers in shortening and repeat the experiment. Your child will notice that, with the shortening acting like a protective layer of blubber, they don't feel the cold water nearly as much.

• Bowl of ice water

#17: Static Electricity Butterfly

This experiment is a great way for young kids to learn about static electricity, and it's more fun and visual than just having them rub balloons against their heads. First you'll create a butterfly, using thick paper (such as cardstock) for the body and tissue paper for the wings. Then, blow up the balloon, have the kids rub it against their head for a few seconds, then move the balloon to just above the butterfly's wings. The wings will move towards the balloon due to static electricity, and it'll look like the butterfly is flying.

• Tissue paper
• Thick paper
• Glue stick/glue

#18: Edible Double Helix

• Teaches Kids About: Genetics

If your kids are learning about genetics, you can do this edible double helix craft to show them how DNA is formed, what its different parts are, and what it looks like. The licorice will form the sides or backbone of the DNA and each color of marshmallow will represent one of the four chemical bases. Kids will be able to see that only certain chemical bases pair with each other.

• 2 pieces of licorice
• 12 toothpicks
• Small marshmallows in 4 colors (9 of each color)
• 5 paperclips

#19: Leak-Proof Bag

• Teaches Kids About: Molecules, plastics

This is an easy experiment that'll appeal to kids of a variety of ages. Just take a zip-lock bag, fill it about ⅔ of the way with water, and close the top. Next, poke a few sharp objects (like bamboo skewers or sharp pencils) through one end and out the other. At this point you may want to dangle the bag above your child's head, but no need to worry about spills because the bag won't leak? Why not? It's because the plastic used to make zip-lock bags is made of polymers, or long chains of molecules that'll quickly join back together when they're forced apart.

• Zip-lock bags
• Objects with sharp ends (pencils, bamboo skewers, etc.)

#20: How Do Leaves Breathe?

• Teaches Kids About: Plant science

It takes a few hours to see the results of this leaf experiment , but it couldn't be easier to set up, and kids will love to see a leaf actually "breathing." Just get a large-ish leaf, place it in a bowl (glass works best so you can see everything) filled with water, place a small rock on the leaf to weigh it down, and leave it somewhere sunny. Come back in a few hours and you'll see little bubbles in the water created when the leaf releases the oxygen it created during photosynthesis.

• Large bowl (preferably glass)
• Magnifying glass (optional)

#21: Popsicle Stick Catapults

Kids will love shooting pom poms out of these homemade popsicle stick catapults . After assembling the catapults out of popsicle sticks, rubber bands, and plastic spoons, they're ready to launch pom poms or other lightweight objects. To teach kids about simple machines, you can ask them about how they think the catapults work, what they should do to make the pom poms go a farther/shorter distance, and how the catapult could be made more powerful.

• Popsicle sticks
• Rubber bands
• Plastic spoons
• Paint (optional)

#22: Elephant Toothpaste

You won't want to do this experiment near anything that's difficult to clean (outside may be best), but kids will love seeing this " elephant toothpaste " crazily overflowing the bottle and oozing everywhere. Pour the hydrogen peroxide, food coloring, and dishwashing soap into the bottle, and in the cup mix the yeast packet with some warm water for about 30 seconds. Then, add the yeast mixture to the bottle, stand back, and watch the solution become a massive foamy mixture that pours out of the bottle! The "toothpaste" is formed when the yeast removed the oxygen bubbles from the hydrogen peroxide which created foam. This is an exothermic reaction, and it creates heat as well as foam (you can have kids notice that the bottle became warm as the reaction occurred).

• Clean 16-oz soda bottle
• 6% solution of hydrogen peroxide
• 1 packet of dry yeast
• Dishwashing soap

#23: How Do Penguins Stay Dry?

Penguins, and many other birds, have special oil-producing glands that coat their feathers with a protective layer that causes water to slide right off them, keeping them warm and dry. You can demonstrate this to kids with this penguin craft by having them color a picture of a penguin with crayons, then spraying the picture with water. The wax from the crayons will have created a protective layer like the oil actual birds coat themselves with, and the paper won't absorb the water.

• Penguin image (included in link)
• Spray bottle
• Blue food coloring (optional)

#24: Rock Weathering Experiment

• Teaches Kids About: Geology

This mechanical weathering experiment teaches kids why and how rocks break down or erode. Take two pieces of clay, form them into balls, and wrap them in plastic wrap. Then, leave one out while placing the other in the freezer overnight. The next day, unwrap and compare them. You can repeat freezing the one piece of clay every night for several days to see how much more cracked and weathered it gets than the piece of clay that wasn't frozen. It may even begin to crumble. This weathering also happens to rocks when they are subjected to extreme temperatures, and it's one of the causes of erosion.

• Plastic wrap

#25: Saltwater Density

• Teaches Kids About: Water density

For this saltwater density experiment , you'll fill four clear glasses with water, then add salt to one glass, sugar to one glass, and baking soda to one glass, leaving one glass with just water. Then, float small plastic pieces or grapes in each of the glasses and observe whether they float or not. Saltwater is denser than freshwater, which means some objects may float in saltwater that would sink in freshwater. You can use this experiment to teach kids about the ocean and other bodies of saltwater, such as the Dead Sea, which is so salty people can easily float on top of it.

• Four clear glasses
• Lightweight plastic objects or small grapes

#26: Starburst Rock Cycle

With just a package of Starbursts and a few other materials, you can create models of each of the three rock types: igneous, sedimentary, and metamorphic. Sedimentary "rocks" will be created by pressing thin layers of Starbursts together, metamorphic by heating and pressing Starbursts, and igneous by applying high levels of heat to the Starbursts. Kids will learn how different types of rocks are forms and how the three rock types look different from each other.

• Toaster oven

#27: Inertia Wagon Experiment

• Teaches Kids About: Inertia

This simple experiment teaches kids about inertia (as well as the importance of seatbelts!). Take a small wagon, fill it with a tall stack of books, then have one of your children pull it around then stop abruptly. They won't be able to suddenly stop the wagon without the stack of books falling. You can have the kids predict which direction they think the books will fall and explain that this happens because of inertia, or Newton's first law.

• Stack of books

#28: Dinosaur Tracks

• Teaches Kids About: Paleontology

How are some dinosaur tracks still visible millions of years later? By mixing together several ingredients, you'll get a claylike mixture you can press your hands/feet or dinosaur models into to make dinosaur track imprints . The mixture will harden and the imprints will remain, showing kids how dinosaur (and early human) tracks can stay in rock for such a long period of time.

• Used coffee grounds
• Wooden spoon
• Rolling pin

#29: Sidewalk Constellations

• Teaches Kids About: Astronomy

If you do this sidewalk constellation craft , you'll be able to see the Big Dipper and Orion's Belt in the daylight. On the sidewalk, have kids draw the lines of constellations (using constellation diagrams for guidance) and place stones where the stars are. You can then look at astronomy charts to see where the constellations they drew will be in the sky.

• Sidewalk chalk
• Small stones
• Diagrams of constellations

#30: Lung Model

By building a lung model , you can teach kids about respiration and how their lungs work. After cutting off the bottom of a plastic bottle, you'll stretch a balloon around the opened end and insert another balloon through the mouth of the bottle. You'll then push a straw through the neck of the bottle and secure it with a rubber band and play dough. By blowing into the straw, the balloons will inflate then deflate, similar to how our lungs work.

• Plastic bottle
• Rubber band

#31: Homemade Dinosaur Bones

By mixing just flour, salt, and water, you'll create a basic salt dough that'll harden when baked. You can use this dough to make homemade dinosaur bones and teach kids about paleontology. You can use books or diagrams to learn how different dinosaur bones were shaped, and you can even bury the bones in a sandpit or something similar and then excavate them the way real paleontologists do.

• Images of dinosaur bones

#32: Clay and Toothpick Molecules

There are many variations on homemade molecule science crafts . This one uses clay and toothpicks, although gumdrops or even small pieces of fruit like grapes can be used in place of clay. Roll the clay into balls and use molecule diagrams to attach the clay to toothpicks in the shape of the molecules. Kids can make numerous types of molecules and learn how atoms bond together to form molecules.

• Clay or gumdrops (in four colors)
• Diagrams of molecules

#33: Articulated Hand Model

By creating an articulated hand model , you can teach kids about bones, joints, and how our hands are able to move in many ways and accomplish so many different tasks. After creating a hand out of thin foam, kids will cut straws to represent the different bones in the hand and glue them to the fingers of the hand models. You'll then thread yarn (which represents tendons) through the straws, stabilize the model with a chopstick or other small stick, and end up with a hand model that moves and bends the way actual human hands do.

• Straws (paper work best)
• Twine or yarn

#34: Solar Energy Experiment

• Teaches Kids About: Solar energy, light rays

This solar energy science experiment will teach kids about solar energy and how different colors absorb different amounts of energy. In a sunny spot outside, place six colored pieces of paper next to each other, and place an ice cube in the middle of each paper. Then, observe how quickly each of the ice cubes melt. The ice cube on the black piece of paper will melt fastest since black absorbs the most light (all the light ray colors), while the ice cube on the white paper will melt slowest since white absorbs the least light (it instead reflects light). You can then explain why certain colors look the way they do. (Colors besides black and white absorb all light except for the one ray color they reflect; this is the color they appear to us.)

• 6 squares of differently colored paper/cardstock (must include black paper and white paper)

#35: How to Make Lightning

• Teaches Kids About: Electricity, weather

You don't need a storm to see lightning; you can actually create your own lightning at home . For younger kids this experiment requires adult help and supervision. You'll stick a thumbtack through the bottom of an aluminum tray, then stick the pencil eraser to the pushpin. You'll then rub the piece of wool over the aluminum tray, and then set the tray on the Styrofoam, where it'll create a small spark/tiny bolt of lightning!

• Pencil with eraser
• Aluminum tray or pie tin
• Styrofoam tray

#36: Tie-Dyed Milk

• Teaches Kids About: Surface tension

For this magic milk experiment , partly fill a shallow dish with milk, then add a one drop of each food coloring color to different parts of the milk. The food coloring will mostly stay where you placed it. Next, carefully add one drop of dish soap to the middle of the milk. It'll cause the food coloring to stream through the milk and away from the dish soap. This is because the dish soap breaks up the surface tension of the milk by dissolving the milk's fat molecules.

• Shallow dish
• Milk (high-fat works best)

#37: How Do Stalactites Form?

Have you ever gone into a cave and seen huge stalactites hanging from the top of the cave? Stalactites are formed by dripping water. The water is filled with particles which slowly accumulate and harden over the years, forming stalactites. You can recreate that process with this stalactite experiment . By mixing a baking soda solution, dipping a piece of wool yarn in the jar and running it to another jar, you'll be able to observe baking soda particles forming and hardening along the yarn, similar to how stalactites grow.

• Safety pins
• 2 glass jars

Summary: Cool Science Experiments for Kids

Any one of these simple science experiments for kids can get children learning and excited about science. You can choose a science experiment based on your child's specific interest or what they're currently learning about, or you can do an experiment on an entirely new topic to expand their learning and teach them about a new area of science. From easy science experiments for kids to the more challenging ones, these will all help kids have fun and learn more about science.

45 Easy Science Experiments for Kids

Hello, STEM! These simple DIY activities can be done at home or in school.

We've been independently researching and testing products for over 120 years. If you buy through our links, we may earn a commission. Learn more about our review process.

Imagine blowing the biggest bubbles imaginable — or even making bubbles within bubbles. Or sending vessels — rockets, tea bags, airplanes — soaring through the sky for impossible distances. Now imagine making things explode, or change colors, or reveal hidden messages with just a few simple mixtures.

First off, it's good to start them off with the scientific method. Give them a journal to record their observations, questions, hypotheses, experiments, results and conclusions. As always, safety counts: wear goggles and coats or aprons if need be (sometimes kids get a kick out of how scientific the protective gear makes them look), and always make sure that the kids are supervised when doing them. (Warning: Some of these are messy!)

These experiments are mostly designed for preschoolers through elementary schoolers — with a couple that are either demonstrations or better for older kids — but if you have a younger one, you can check out these 1-year-old learning activities , toddler learning activities and preschool/kindergarten learning activities , some of which also cover STEM subjects.

Floating Fish

Here's another one that deals with solubility and density.

• Draw the outline of a fish on the bottom of a glass plate or tray in dry-erase marker. Retrace your drawing to make sure all the lines are connected. Let dry for a minute or two.
• Fill the measuring cup with tap water. Place the pour spout just inside the corner of the dish and add water very slowly until it just covers the bottom. Be careful not to pour water directly onto your drawing or make splashes near it. The water will move toward your drawing, eventually surrounding it. Observe what happens. If the water splashes or it doesn’t work on your first try, empty the dish, erase the drawing with a paper towel, dry off the dish, and try again.
• Tilt the dish slightly from side to side. What happens? Jot it down.

The ink in dry erase markers is engineered to be slippery. It’s made with a chemical that causes it to easily release from surfaces. (Permanent markers are made with a chemical that makes the ink stick to surfaces, so be sure not to use these in your experiment!)

The easy-release ink lets go from a surface, but why does it float? There are two reasons. First, dry erase ink isn’t soluble, which means it won’t dissolve in water. Second, dry erase ink is less dense than the water, so it becomes buoyant, meaning it can float. When you tilt the dish, the fish moves around on the water’s surface.

Brush, Brush!

This one will really get them into brushing their teeth once they scientifically prove all the good things that toothpaste can do.

• Write on sticky notes: Soda 1, Soda 2, Juice 1, and Juice 2. Place them in a row on a counter.
• Fill two glasses halfway with brown soda and place behind the Soda 1 and Soda 2 sticky notes. Fill two glasses halfway with lemon juice and place behind the Juice 1 and Juice 2 sticky notes.
• Carefully place one egg in the bowl. Squeeze a big dollop — about one tablespoon — of toothpaste on top of the egg and gently rub the toothpaste all around with your hands until the egg is completely covered in a thick layer of toothpaste. Repeat with a second egg.
• Gently submerge the toothpaste-covered eggs into the liquids: one egg in the glass labeled Soda 1 and the other egg in the glass labeled Juice 1. Wash and dry your hands.
• Gently submerge the remaining eggs, without toothpaste on them, in the remaining glasses: one in the glass labeled Soda 2 and the other in the glass of juice labeled Juice 2. Wash and dry your hands. Leave the eggs in the glasses for 12 hours.
• After 12 hours, remove the eggs from the glasses of soda one at a time. Rinse them in cool water and pat them dry with the towel. Place each egg by the sticky note of the glass it was in. Are the eggs the same or different colors?
• Remove the eggs from the glasses of juice one at a time. Rinse them under the faucet and pat them dry. Place each egg by the sticky note of the glass it was in. Feel the eggs gently. Does one feel stronger or weaker than the other?
• Write down your observations in your science notebook.

The eggshells in this experiment represent the enamel (outer coating) on your teeth. Toothpaste cleans your teeth and prevents stains: it removes food and drink particles that are stuck on your teeth. Teeth can be stained easily by dark-colored liquids like cola, coffee or tea. The egg without toothpaste will be brown and discolored. The egg covered in toothpaste was protected from turning brown.

Toothpaste also protects your pearly whites from decay (breaking down). The egg without toothpaste left in the lemon juice was worn down and soft to the touch, while the egg that was protected with toothpaste is stronger. The lemon juice is acidic, and those acids broke down the shell just as acidic drinks can wear away your tooth enamel. When a tooth is worn down, a cavity can form more easily. But the fluoride in toothpaste mixes with your saliva to create a protective coating around your tooth enamel. It helps keep your teeth strong and cavity-free.

Milk Bottle Xylophone

No for an experiment in sound!

• Arrange six glass jars or bottles, all the same size with no lids, in a line. What will each jar sound like when you tap it with a spoon? Make a prediction, then tap each jar. Record your observations.
• Next, put water in each of the jars. Pour 1⁄4 cup (60 ml) of water into the first jar. Add 1⁄2 cup (120 ml) of water to the second jar. Continue in 1⁄4-cup increments, adding 3⁄4 cup (180 ml) of water to the third jar, 1 cup (240 ml) of water to the fourth jar, 11⁄4 cups (300 ml) of water to the fifth jar, and 11⁄2 cups (360 ml) to the sixth jar. Add a couple of drops of food coloring to each jar.
• What will each jar sound like? Will they sound the same or different than when the container was empty? Will they sound the same or different from one another? Record your predictions.
• Tap each jar with a metal spoon. Write down your observations about each jar’s pitch (how high or low a sound is) in your notebook.

Sound waves are created by vibrations, which are back-and-forth movements that are repeated again and again. Pitch depends on the frequency of the waves — how many are created each second. A high pitch is created by high-frequency sound waves, and can sound squeaky. A low pitch is created by low-frequency sound waves, and sounds deep and booming.

When you tapped the jar, it vibrated. The vibrations traveled from the jar to the water to the air and eventually to your ears. The jars with more water had a low pitch. The sound waves vibrated more slowly because they had more water to travel through. The jars with less water had higher pitches. The sound waves vibrated faster because they had less water to travel through. A jar with no water in it makes the highest pitch because it has the least substance to travel through.

"Elephant Toothpaste"

Okay, elephants don't really brush with this stuff, which is made from a chemical reaction between hydrogen peroxide, yeast, dish soap and a few other simple ingredients. But this experiment has a big "wow" factor since, when the substances are mixed, the "toothpaste" foams out of the bottle. You can use it to teach kids about catalysts and exothermic reactions.

By making a salt dough with coffee grounds and pressing various shapes into it (toy dinosaur feet, seashells), kids can get a better understanding of how fossils are made. If you poke a hole in the top before it dries, the kids can hang their "fossils" up in their rooms.

Chromatography Flowers

Chromatography is the process of separating a solution into different parts — like the pigments in the ink used in markers. If you draw stripes around a coffee filter, then fold it up and dip the tip in water, the water will travel up the filter and separate the marker ink into its different pigments (in cool patterns that you can display as a craft project). This family made the end-result even brighter by adding an LED circuit to the center.

Water Walking

You'll need six containers of water for this one: three with clear water, one with red food coloring, one with blue coloring, and one with yellow coloring. Arrange them in a circle, alternating colored and clear containers, and make bridges between the containers with folded paper towels. Your kids will be amazed to see the colored water "walk" over the bridges and into the clear containers, mixing colors, and giving them a first-hand look at the magic of capillarity.

10 of the BEST Science Experiments for Kids

May 28, 2021 By Emma Vanstone 1 Comment

Here at Science Sparks, we’ve tried a lot of science experiments over the years; some have been brilliant on the first go, some have taken a LOT of tweaking, and some have been a complete disaster! Most have been great fun, whatever the outcome. To save you and your budding scientist the disasters, I’ve put together a list of the BEST science experiments for kids !

The BEST Science Experiments for Kids

1. mini baking soda rocket.

Up first is my mini baking soda powered rocket . A fun way to do this activity is to split it into two parts.

Design the Rocket

It needs to stand up with a gap between where the cork fits and the floor. Remember not to add too many decorations or it will be too heavy.

Launch the Rocket

Experiment with different amounts of baking soda and vinegar to find the best rocket fuel !

The rocket must be placed on a hard surface to launch.

2. Skittles Experiment

If you haven’t tried the good old skittles experiment, where HAVE you been?

Pour water over Skittles on a plate and watch as the colours dissolve from the candy into the water.

Investigate using different temperatures of water and even different types of sweets. If you have any Skittles left over at the end, another idea is to try some candy chromatography .

3. Elephants Toothpaste

Babble Dabble Do has the most amazing version of this explosive science activity. Elephant toothpaste is always fun!

4. Colour Changing Potions

Everyone loves a fizzy potion, but it’s even better if you can get it to change colour!

If you use red cabbage indicator juice as the base liquid for a traditional baking soda and vinegar potion , it will change colour as it reacts.

5. Chromatography

Chromatography is a visual way to separate the different dyes in inks. All you need is some non-washable felt tip pens, filter paper and water. It’s a brilliant colourful science investigation for kids .

A fun twist on this activity is to use candy instead of felt-tip pens. Watch as the candy colours separate as they travel up the filter paper.

6. Create a Chain Reaction or Rube Goldberg Machine

A Rube Goldberg machine uses the principle of a chain reaction to achieve an end goal. Examples are popping a balloon or delivering an item to someone.

7. Lolly Stick Explosion

A craft or lolly stick explosion is a fantastic group activity or science demonstration.

They take some time to set up but are worth the effort.

Oobleck is made from cornflour and water . It’s called a Non-Newtonian liquid as it feels solid when you squish it between your fingers but turns back into a liquid when the pressure is released.

9. Absorbing with Sugar Cubes

This activity uses sugar cubes to learn about absorption and properties of materials , especially whether they are waterproof or not.

The idea is to build a tower of sugar cubes and test different materials to see which can save the higher cubes. It’s a lovely visual, hands-on experiment.

10. Bouncy Egg

Do you know how to make an egg bounce ?

First, you need to remove the shell by soaking the egg in vinegar. This leaves just the membrane behind. Once you’ve washed off the shell, you can bounce the egg.

Take care with this one, as eventually, the egg will break!

What do you think? Have I missed any? What would you add to the list? Perhaps a mento geyser ?

Frequently Asked Questions

At what age can you start stem.

You can start exploring STEM with your child from day one. After all, we understand the world around us through STEM. All of our senses, like sound and vision, are all components of science that we experience very early on. As we get older we learn about nature and how the things around us work.

How do you teach a toddler STEM?

The best way to teach STEM is through hands on experience. Play based learning is the best approach when trying to explain concepts to kids. Keep it simple, age appropriate, and allow kids to explore and problem solve by themselves.

Do kids like STEM?

Absolutely. I have yet to meet a child who didn’t have a natural curiosity about the world around them. The key is to make it fun, without any pressure, because that is how they learn best. It’s also a great way to create toddlers and preschoolers who are intrinsically motivated to learn more.

Water STEM Activities for kids

12 ways to make science fun for your kids at home

The vinegar and baking soda volcano is a science fair classic, but making science fun for your kids can mean a lot more than making a mess of your kitchen.

If you're looking for a way to bring more science into your home, there are plenty of fun and even delicious ways to get kids excited about biology, chemistry, and physics — without a single worksheet.

Check out these 11 science projects for kids that are perfect for hands-on learning.

1. Make 'quicksand' with cornstarch

What kids will learn about: non-Newtonian fluids

While this might seem like a big task, you've likely done this before. When you slowly mix about 10 parts cornstarch to one part water, you create a liquid with the consistency of honey, and the properties of quicksand.

This is how it works: When you mix the cornstarch into the water, you create a suspension, which is when one substance is dispersed inside another. This makes the mixture act like a solid when pressure is applied, and a liquid when it's allowed to flow freely.

If you smack, slap, or scoop the mixture, it will feel solid since you'll be pushing the cornstarch particles closer together. Slowly run your fingers through it or pour it out, and it will flow like a liquid.

These mixtures are called non-Newtonian fluids, referring to Isaac Newton's observation that substances typically become more fluid when they're heated and viscous when they're cooled. Those substances, like honey, are Newtonian fluids.

Since the cornstarch goop's consistency is affected by pressure as well, it's considered a non-Newtonian fluid. Quicksand — a suspension of sand in water — works the same way.

2. Bake a paleontology cake

What kids will learn about: dinosaurs

There are plenty of cool ways to use science to create food — and we'll get to one later — but sometimes all you need is a cake to start an appetite for knowledge.

These paleontology-themed pastries don't automatically teach your children anything about dinosaurs, but it can be a delicious way to get them interested in learning more. Use them as a way to keep their attention as you teach them about the lizards that once ruled the Earth.

The above video shows how to make a very cool cake which lets kids brush aside cookie crumbs to reveal a dinosaur fossil. If you're after something a bit simpler with less potential for mess, you can also decorate a cake with a few fossil toys .

3. Create an electromagnet

What kids will learn about: electromagnetism

Making an electromagnet is a middle school science-class staple, and it's an easy project to do with a few small items from a hardware store. Simply wrap copper wire around a nail, connect the ends of the wire to a battery, and watch the magnetic magic unfold.

The magnetic field gets amplified with each additional loop around the wire, and your kids can test out different wire gauges, lengths, and materials to see which will make the strongest magnets.

4. Make pepper swim with dish soap

What kids will learn about: surface tension

Surface tension is a tricky concept to explain to younger children, but an easy and engaging thing to show them.

Here's how to do the pepper soap trick you've probably seen all over the internet:

Sprinkle a bunch of pepper on the surface of a bowl of water,

Then have a kid dip her finger in dish soap

Next, gently touch the surface of the water.

The pepper will jet to the edge of the bowl because the soap broke the surface tension of the water. Tah-dah!

Surface tension is the result of the surface-level molecules of water being pulled downward by attraction to other molecules. This holds them in place and allows particles like pepper to float on them.

Because soap is another highly attractive substance, it will pull the water molecules near it and break the surface tension. This flings the pepper particles out to the edges of the bowl, where the surface tension remains.

You can also do the same experiment with milk and food coloring .

5. Extract DNA from split peas

What kids will learn about: what DNA looks like

This might sound deceptively tricky, but with some household supplies and a little bit of lab equipment, you can help show your kids what DNA looks like. The video above walks you through the whole process, which involves breaking down the subject, using salt and meat tenderizer to release the DNA, and extracting it with alcohol.

An individual DNA molecule would be too small to see with the naked eye, but this experiment makes the long, sticky stands visibly tangle together.

6. Suck an egg into a bottle with fire

What kids will learn about: air pressure and vacuums

This is a surefire way to wow your kids with nothing more than a hard-boiled egg, a glass bottle, a lighter, and some paper. Take strip of paper, light it on fire, put it inside a glass bottle, and let the smoke reach the brim. As soon as it does, place the egg narrow-side down at the mouth of the bottle, and it will slowly get sucked into the bottle.

As the smoke fills the bottle and it heats up, the air inside expands. Once the flame is cut off by the egg's seal of the bottle, the air begins to cool and contract, creating a vacuum that sucks the egg in.

If you can't stand the smell of hard-boiled eggs or can't find the right size bottle, you can use balloons instead.

7. Make a carnation change colors

What kids will learn about: the vascular system of flowers

It's not the quickest science experiment, but it might be one of the coolest. Take a few white carnations, vases and different types of food coloring. Dye the water, then place the flowers in the different vases to watch them change color day by day.

You can even split stems to color one side of the carnation and not the other, or color it two different colors.

8. Make hot maple ice cream

What kids will learn about: molecular gastronomy

At its core, molecular gastronomy is using chemicals and creative cooking methods to create food that flips its usual form and function on its head. More home chefs have been trying out these techniques over the past few years, and you can join them by using a little bit of methyl cellulose to make a hot ice cream that melts as it cools.

Methyl cellulose is a derivative of plant cell walls, and creates gels only when it heats up. The recipe in the video above shows you how to make it yourself, and you can get the key ingredient for as cheap as $7.99 .

9. Build Heron's Fountain

What kids will learn about: air and pneumatic pressure

This modern adaptation of a first-century Alexandrian fountain is a great way to introduce kids to air and pneumatic pressure. Water and air pressure are moved through a series of tubes, which draw water down from the top, through the bottom, and up to the top again.

10. Explain why the sky is blue with milk, water, and a flashlight

What kids will learn about: rayleigh scattering.

Rayleigh scattering is what happens to light when it passes through the atmosphere. As light travels from the sun to Earth, it's absorbed and emitted by tiny particles, which scatter white light into different colors. Blue and violet are scattered the most, and because the sun emits more energy as blue light (which our eyes pick up better), our sky looks blue.

You can replicate this effect with a glass of water, milk, and a flashlight. Shine the light into the glass of water as you slowly add drops of milk. Once there are enough protein and fat particulates from the milk in the glass, the water will look blue.

11. Make your own rock candy

What kids will learn about: crystallization

If the dino cake and hot ice cream weren't enough, you can teach your kids all about crystallization with some rock candy. Simply mix sugar into water until the sugar stops dissolving. Then, tie a clean string to a butter knife laying across the top of a glass and pour in the solution.

Keep the glass covered with a paper towel or plastic wrap to keep out bacteria, and watch the crystals grow each day.

12. Bend chicken bones

What kids will learn about: calcium in bones

Like the carnation experiment, this science experiment takes a bit of time. However it's also incredibly simple — and a great excuse to order some fried chicken.

Simply immerse a clean, dry chicken bone in a jar of vinegar and leave it to soak for a week. Take the bone out, and you should be able to bend it fairly easily. This is due to the vinegar dissolving the calcium, which is what makes bones rigid. It's a great way to demonstrate to kids why they need to drink their milk or eat other calcium-rich foods.

And remember: all these science experiments for kids should be fun. They don't need to know they're learning something amazing and new.

What Is Physics for Kids?

Physics is, most simply put, the study of matter and energy and the interaction between the two .

Physics is like the rulebook of the universe. It helps us understand how everything around us works, from tiny atoms to the vastness of space. When we study physics, we learn about motion (like why things move), forces (like pushes and pulls), energy (what makes things happen), electricity, magnetism, and more. It’s like solving puzzles about how the world functions.

Kids can learn more about the world around them through fun physics experiments like the ones below and deep thinking!

Fun with Science: 27 Sensory Science Experiments for Kids

If you told my 15-year-old self I would one day be sitting at this desk writing a post about sensory science experiments for kids, I wouldn’t have believed you.

And yet, here we are, LOL.

While I did the mandatory biology, chemistry, and geology courses in middle and high school, I found each subject tedious, boring, and difficult, and figured I just wasn’t smart enough to be a scientist.

I avoided anything to do with science from grade 10 onwards, and it wasn’t until my daughter started telling me about all of the amazing science experiments she did in preschool and kindergarten that I started poking around on Pinterest for science experiments for kids we could do together at home, and I was pleasantly surprised with all of the fun ideas I found.

As it turns out, science can actually be fun!

RELATED:  100+ Fun STEM / STEAM Projects and Why They Work

And with a huge shift towards STEM learning , finding ways to get kids interested in science is becoming more important than ever. Whether you’re looking for sensory science experiments for kids in preschool and kindergarten, or amazing science experiments for kids in elementary school and beyond, we’ve got 27 super cool ideas below!

What is Science?

Simply put, science refers to the act of studying the world around us.

There are all different types of science – biology, chemistry, physics, botany, paleontology, geology, astronomy, etc. – and scientists study these through observation, hypotheses, prediction, and experimentation.

Why Is It Important to Do Science Experiments with Kids?

With more classrooms focusing on STEM education – a multifaceted approach to learning that combines science, technology, engineering, and math to develop a child’s problem solving and critical thinking skills while also encouraging creativity, communication, and teamwork – finding ways to foster a love for science is becoming more important than ever. Engaging children in science experiments at home and in the classroom:

• Encourages higher level thinking
• Teaches children not to accept the status quo and make their own predictions
• Fosters an interest and excitement for research
• Provides opportunities for failure in a safe environment
• Encourages innovative and creative thinking
• Teaches children how to work collaboratively

Unfortunately, kids are often taught that science is boring and difficult, and if parents and teachers don’t intervene, these negative thoughts can persist through high school and beyond, making children less interested in and willing to participate in STEM-based subjects. This can have a huge impact on their academic growth and development, not to mention their career paths.

How to Get Kids Excited About Science

Start young. It’s never too early to get kids excited about science and other important areas of education, and the internet is filled with all kinds of amazing science experiments for kids of all ages. Sensory science experiments tend to work best with younger kids as they are more hands on, and we’ve rounded up some fabulous ideas below to inspire you!

Make it hands on. Instead of getting kids to MEMORIZE scientific facts and equations, get them involved! Not only will this make your lesson plans more engaging and fun, but it will also help your students retain more information.

Appeal to your child’s interests. If you’re finding it difficult to foster a love for science in your child, find ways to apply it to the things he or she loves. Think outside the box and use props, materials, and/or toys that appeal to your child’s interests to capture his or her attention and make learning fun instead of tedious.

Get online. There’s no question that our children love spending time watching TV and on their iPad, so use this to your advantage! Find science-themed TV shows and search YouTube for inspirational videos and tutorials your child might find interesting.

Be a good role model. Instead of telling your child how much you hated science when you were in school (ahem…), model everyday inquisitive behavior to foster a love for learning in your child. You will be amazed at what this simple change in mindset can do!

Make it fun!  From sensory science experiments for preschoolers, to amazing science experiments for kids in elementary school, there are SO MANY WAYS you can make science fun for kids. We’re rounded up 27 ideas for kids aged 3 to 13 below to help get you started!

Thanks Flora!

Keep this going please, great job!

Yeah,I would say the same. Great job!

My name is Erin Marie. I am a fellow blogger. I LOOOOVE your website and use it all of the time with my daughter. So, I nominated you for the Liebster Award.

You can view the nomination post here: https://luckyinluv.com/liebster-award

Thank You! Erin Marie

Thank you for your exciting, educational and easy-to-follow experiments and activities. I help run a boys’ club (ages 7 to 11) and we are always looking for activities which will make their brains work harder while their hands have a bit of fun! I am looking forward to receiving your emails with more of these science activities.

You take experiments from Home Lab App in Google play

I haven’t heard of that app, so no, I haven’t taken any of their experiments. Although, many of them are ‘common’ science experiments that are available in many science textbooks and the like, so there’s likely to be unintentional double up.

is there a way to print the snowflake activity directions without having to print 20 pages? Thanks!

Ah, yes, I’m working on adding an easy ‘print instructions’ feature. sorry it’s not up and running yet, but watch this space!
