65 Science Experiments for Kids: Have a Blast at Home

Is your kid bored at the weekends or while on school vacation? Are they couch potato-ing in front of the TV again? I know a brilliant way to keep your child entertained and engage their brain: science experiments.

Whether your child is intrigued by the thought of Imploding Cans or a Lemon Volcano, I’ve put together a list of 65 dazzling science experiments for kids! No need for a fancy science lab — you can do these all from the comfort of your home.

I’ll let you know exactly how to carry out each experiment. Gone are the days when there was nothing to do. Now you have 65 theories to test out!

Easy Science Experiments Kids Will Enjoy

Safety tips, faqs about science experiments for kids.

From making a cloud in a bottle to homemade bouncy balls, here are 65 easy science projects for kids to try. Plus, most use household items, making this a cheap way to pass the time.

1. Cloud in a Bottle

Tightly secure the lid on an empty plastic water bottle. Twist the bottom of the water bottle as tightly as possible. This will compress the air and push all the molecules inside together.

When you open the water bottle, the molecules expand, releasing the pressure and creating an instant cloud.

2. Floating Fish

Learn about solubility and density with this fun experiment. On the bottom of a glass plate, draw the outline of a fish with a dry-erase marker.

After a couple of minutes, slowly pour tap water into the corner of the dish until it covers the plate. The water will move towards the fish drawing, surrounding it. Tilt the plate from side to side and watch as the fish drawing starts to float!

3. Lava Lamp

Learn about density and make a lava lamp at home. Add two inches of baking soda to the bottom of a jar, then fill the rest with vegetable oil until full. These two ingredients won’t mix.

Combine ¼ cup of vinegar with a bit of food coloring in a separate cup. Mix together before pouring the solution into the jar with oil and baking soda.

Turn off the lights and shine a flashlight on your lava lamp!

4. Foamy Fountain (Elephant’s Toothpaste)

In this experiment, kids will make foam with a few household ingredients. In scientific terms, this is called an Exothermic Reaction.

Pour ¾ cup of hydrogen peroxide into a bottle. Add 10 drops of food coloring and one tablespoon of dish soap. Swirl it around to mix.

Combine three tablespoons of warm water and one tablespoon of dry yeast in a separate cup. Mix for 30 seconds.

Use a funnel to pour the yeast-water combination into the bottle and watch it fantastically foam!

Don’t touch the foam. We know it’s tempting, but it contains peroxide, which can irritate your skin and eyes.

5. Magic Milk

Pour whole milk into a shallow pie dish with a flat surface. Add a few drops of food coloring to different parts of the dish. You can use tons of different colors!

In a separate bowl, pour some dish soap. Dip a cotton swab into the dish soap and gently touch the surface of the milk with the swab.

The soap will lower the surface tension of the milk, and the colors will burst and swim around.

6. Egg in a Bottle

Did you know you can fit an egg in a bottle without breaking it? Firstly, boil and peel your egg. Then grab a glass bottle (no plastic!) and ensure that the opening is smaller than the diameter of the egg.

With an adult’s help, light three matches and drop them into the bottle. Place the egg at the bottle’s opening with the wide end pointing up. The egg will slowly squeeze into the bottle as the fire goes out!

7. Floating Ping Pong Ball

Levitate a ping pong ball with Bernoulli’s Principle! Make a paper funnel using thick card. With a grown-up’s help, cut a small hole in the bottom of the funnel.

Insert a straw into the bottom of the funnel and secure it in place with putty or tape.

Add a ping pong ball (or DIY foil ball) into the funnel and put the long end of the straw in your mouth. Blow into the straw and watch the ball levitate because of the high speed and low-pressure air.

8. Imploding Cans

Fill up a few empty soda cans with a bit of water. Then, fill up a large bowl with ice cubes and water.

Heat a flat frying pan on the stove and carefully stand your cans on the frying pan until they are hot. Using tongs, transfer the hot cans one at a time into the ice water.

When the cans drastically change temperature, they implode on themselves and crush inwards.

This is one for parents to do and kids to watch. It’s not safe for kids to do on their own.

9. Eggs and Toothpaste

Learn about the power of toothpaste in this shocking science project for kids. Fill up four glasses, two with soda and two with lemon juice. Then cover two eggs in toothpaste and pop one into a soda glass and another into the lemon juice glass.

Next, place two more eggs into the remaining glasses. This time, they’re not covered in toothpaste. Leave all the eggs in the glasses for 12 hours.

Once the time is up, remove the eggs, rinse under cool water, and pat dry. You’ll notice that the eggs covered in toothpaste feel and look different than those without. This emphasizes the significance and protective abilities of toothpaste.

10. Black Pepper Trick

Teach kids about surface tension and the power of soap in this fun and easy experiment. Pour a thin layer of water onto a plate. Pour a bit of ground pepper all over the water’s surface.

Then pour a tiny amount of dish soap onto your finger. Dip your finger into the water, and you’ll notice the pepper quickly zoom away from your finger.

Need something for your science fair project? People will love watching this one in action!

11. Ice Cream in a Bag

Have fun and try something yum! Pour four ounces of milk and cream, ¼ teaspoon of vanilla, two tablespoons of sugar, two teaspoons of vanilla, and food coloring (optional) into a zip-bag and ensure it’s securely closed.

Place the bag into a larger zip-bag and fill it with ice and a small handful of salt to surround the smaller bag. Zip it shut and hold either side while shaking back and forward for about five to eight minutes.

Yes, your arms will be tired. But in the end, you’ll have ice cream! Open the large bag and remove the smaller bag. Rinse off salt from the bag and open it up. It’s ice cream time!

12. Magic Melting Skittles

Grab a plate and line up Skittles around the edge of the bowl. Pour a little bit of boiling water into the plate to surround the bottom. Watch as the colors from the Skittles slowly melt off and swirl together on the plate.

This experiment has endless possibilities. Try it with different colors and shapes on the plate!

13. Bouncy Egg

Turn a raw egg into a bouncy egg! Simply place the raw egg (uncracked) into a glass. Cover it completely with distilled white vinegar and leave for 24 hours. After 24 hours, you can gently scrape off the eggshell, and you’re left with a squishy, bouncy egg.

14. Grow an Avocado Tree

Wash an avocado pit and insert four toothpicks halfway up the side, on all sides. Suspend the pit over a jar and fill the container with enough water to submerge the lower third of the seed. Make sure the broad side of the pit is facing down.

Keep the jar in a warm place out of direct sunlight and change the water every few days. After a few weeks, roots and sprouts should start appearing.

When the sprouts are about six inches, cut it back three inches. This will encourage more growth. When the stem has grown back again, plant the avocado pit in a 10-inch pot with soil, and voila! Your avocado tree will grow.

15. Make Slime

This exciting experiment will provide days of fun! Mix together ¼ of water and ¼ cup of white school glue in a bowl. Add a few drops of food coloring.

In a separate bowl, combine ½ tablespoon of Borax and another ½ cup of water. Stir to combine. Add the solution to the glue mixture, and enjoy playing with the slime!

16. DIY Rock Candy

On the stove, combine a 1:3 ratio of water and sugar. Bring it to the boil.

Let it cool for 10 minutes before transferring to a large glass or jar. If you want colorful rock candy, add food coloring to the solution and stir.

Pour half a cup of sugar onto a plate. Dampen a wooden skewer in water and roll it around in the sugar. Then place the skewer into the glass jar and secure it in place with a clothespin so it stays in the middle of the jar.

After five days, your rock candy will have formed. Use a skewer to break the piece of rock candy out of the water. Place it inside an empty jar to dry, and yum! You have your own rock candy.

Ask for an adult’s help for this one since you’ll be using high heat.

17. Baking Soda and Vinegar Balloon

Baking soda and vinegar can blow up a balloon without any help from your lungs. Using a funnel, pour about ¼ cup of vinegar into a bottle (with an opening small enough to stretch the mouth of a balloon over).

Put the mouth of the balloon over the funnel and add one tablespoon of baking soda to the balloon. Stretch the balloon over the bottle’s mouth and empty the baking soda into the bottle.

Watch as the balloon fills up with air. More technically, it’s carbon dioxide because that’s what happens when you combine baking soda and vinegar.

18. Frozen Bubbles

Blowing bubbles can be even more fun when the temperatures are below freezing. The bubble solution can freeze on the spot! You can do this with a bubble solution and a bubble wand — wave it around to produce bubbles.

The bubbles will either freeze mid-air, once they fall to the ground, or even while they are still attached to the wand.

Another option is to pour the bubble solution onto a plate or shallow bowl. Use a straw to blow a bubble into the solution. The bubble will slowly freeze, forming ice crystals.

You can pop the bubble and notice how it shatters and crumples rather than disappears like a normal bubble.

19. DIY Phone Speaker

When you don’t have your own Bluetooth speaker, you can easily make one with paper cups and toilet roll tubes. On the toilet roll tube, cut out an opening on one side that will fit the bottom of your phone.

On the paper cups, cut out a small opening to fit the end of the toilet roll tube through. Connect the pieces together, choose your favorite song, and insert your phone speaker into the toilet roll tube.

The system will naturally amplify the sound from the phone! Dancy party time.

20. Invisible Ink

Reveal hidden messages with this science project for kids. Pour ⅓ cup of baking soda and ⅓ cup of water into a bowl. Mix together before adding a cotton swab into the solution and writing a secret message onto a card.

Pour 100 percent grape juice into a cup. Dip in a paintbrush and paint over the secret message to reveal it. This is a great way to teach about acids and bases.

21. Milk Bottle Xylophone

Make music with items you already have in the house. Line up six glass bottles and pour a different amount of water into each jar.

Make music by tapping a metal spoon on each jar. Notice how the amount of liquid in each jar changes the sound waves and vibrations, resulting in a higher and lower pitch.

22. Dancing Raisins

Fill a clear glass with clear soda and fill another glass with water. Place a few raisins in each glass and notice how the raisins dance in the soda liquid but not in water. This is because the gas bubbles carry the raisins up, and when the bubbles pop, the raisins sink again.

23. Exploding Lunch Bag

This chemistry test is a great way to add excitement to a dull Saturday morning!

Fill a zippable lunch bag with ¼ cup of warm water. Add ½ cup of distilled white vinegar. Zip the bag shut.

Place a piece of tissue or paper towel down and pour three teaspoons of baking soda onto the middle. Fold the tissue over itself.

It’s time to be speedy! Open the zippable bag enough to add the baking soda tissue.

Once you’ve added it, quickly shut the bag, put it on the ground and step back. The bag will begin to expand and eventually… BOOM!

Do this experiment outside. You don’t want a mess on your living room floor!

24. Lemon Volcano

Let’s make citrus volcanos! This is a great one for science fair projects.

Cut the top and bottom off a lemon and carve out the insides. Add food coloring to the inside and fill the lemon with baking soda. Mix with a knife and watch as the baking soda starts to fizz out.

You can also try this with different citrus fruits, like an orange or grapefruit. Make it with different colors to have a rainbow volcano collection.

25. Walking Water Rainbow

Place seven identical jars or glasses in a row or a circle. Fill every second jar ¾ full with water, so jars #1, #3, #5, and #7 have water.

Then add a big squirt of red food coloring to jars #1 and #7, yellow to jar #3, and blue to jar #5. Jar #2, #4, and #6 will remain empty.

Fold six paper towels in half (hot-dog style), then in half again, making long, thin pieces of paper towels. Fold each paper towel in half (hamburger-style), so they make a tent shape.

Then place one end of the paper towel in the first cup and the other half in the second cup. Repeat with each paper towel.

Each cup should have two paper towel ends inside unless your cups are in a row. In that case, the first and last cups will only have one paper towel end inside.

After a couple of hours, the paper towels will have soaked up the food coloring using a capillary action. The colors mix together to create the shades of the rainbow: red, orange, yellow, green, blue, indigo, and purple.

26. Rising Water

Fill a shallow bowl with enough water to cover the bottom. You can add food coloring for more fun!

Place a tealight candle in the middle of the water and light it. Quickly place an empty glass over the candle.

The candle will gently burn out while water rises into the glass. This is a great way to teach Charles’s Law, which conveys how when temperature decreases, the volume does, too, allowing water to rise and fill the empty space.

Get an adult to help with the Rising Water experiment, since it involves fire.

27. Bend Water

Run your kitchen or bathroom tap with a very thin stream of water. Blow up a balloon and create static by rubbing it against a towel or your hair. Hold the balloon close to the water and watch as the water bends towards the balloon.

28. Citrus Pops Balloons

Limonene, a component in citrus, has the ability to dissolve rubber, which is a component of balloons (1) . Therefore, when you squirt citrus onto a balloon, it pops!

Blow up a few balloons. Peel an orange, ensuring you have large pieces of the peel to hold.

Hold the peel a few inches from the balloon, with the rind side facing the rubber. Quickly squeeze the peel so the liquid squirts onto the balloon, and it should pop!

Something To Note

Not all balloons will pop through this experiment. If the balloons are made from natural rubber, they will most likely pop easily. But if the rubber is vulcanized, it’s more durable and harder to dissolve.

29. DIY Compass

Never get lost again! To make a compass, stroke a strong magnet down one length of a sewing needle 50 times. Then flip the magnet and the needle, and repeat on the other side.

Cut a cork so it’s about 1.5 centimeters thick. Push the needle through the cork — you may need to use pliers, so ask a parent for help.

Next, fill a bowl with a few inches of water. Place the cork into the water, and it should point North.

30. Sink or Float

Take note of which ones sink and which ones float. Can you determine why?

31. Optical Illusions

Optical illusions are an incredible way to confuse your brain using your eyes. Why not get a book of optical illusions for your kids to flick through all summer? This will keep them entertained — and amazed.

32. Pumpkin Volcano

Cut a hole in the top of a pumpkin and clean out the insides. Pour ¼ cup of baking soda into the pumpkin with a squirt of dish soap and watch the pumpkin start to foam from the top!

33. Create a Marshmallow Catapult

Stack up six popsicle sticks and tie them together with a rubber band on either end. Then tie a wooden spoon and another popsicle stick together at the bottom end of the spoon. Push the large stack of popsicle sticks between the spoon and the second stick until it’s halfway down.

Secure it together by making an “X” with a rubber band where the two sticks meet. Then put a mini marshmallow on the spoon and pull it back slightly.

The marshmallow should fly through the air! If not, adjust your mechanism until it can catapult the marshmallows.

34. Make Ginormous Bubbles

Make the biggest bubbles your eyes have ever seen! Mix together six cups of distilled or purified water with ½ cup of cornstarch.

Add one tablespoon of baking powder, one tablespoon of glycerine, and ½ cup of dish soap. I recommend Blue Dawn dish soap .

Use it with a giant bubble wand. If you need to make your own giant bubble wand, do this beforehand so you can use the bubbles immediately.

35. Magnet Experiment

Fill a glass with water and add a few tablespoons of magnetic fine iron filings . Run magnets up and down the side of the glass and watch the iron fillings move around.

36. Paper Bridge

All you need for this are pieces of paper, two plastic cups, and a bunch of pennies. Create different types of bridges by trying out different designs with the paper. Add one penny at a time to the bridges to discover the strongest bridge design.

37. Shine Up Pennies

Discover how to clean copper pennies using household items. Fill different cups with different liquids, including white vinegar, soapy water, ketchup, and soda. You can fill up the other cups with any liquid you please!

Put a penny in each cup and wait 10 minutes. Then rinse the pennies with water and rub with a paper towel. Which liquid cleans the pennies best?

38. Egg Drop Challenge

The aim here is to drop the egg into the glass of water. So fill a glass full of water (make sure it’s big enough for the egg) and place a piece of cardboard or a small tray on top of the glass. Then place a toilet paper tube on top of the tray before balancing the egg horizontally on the tube.

When you’re ready, strike the tray or cardboard away with your hand, making sure to send it flying away without knocking over the water. The egg will hang in the air for a split second before dropping into the water.

39. Green Pennies

Above, I taught you how to polish pennies. Did you know you can turn pennies green using a very similar method?

Fill up two bowls with ¼ cup of vinegar and one teaspoon of salt. Mix well. Add a few pennies to each bowl.

After 10 minutes, remove the pennies from one bowl, rinse them, and lay them flat to dry on a paper towel.

Take the other pennies from the second bowl and place them onto the paper towel. Don’t rinse! Wait and see what happens.

The pennies that you rinsed will be polished. But the pennies you didn’t rinse will be green. This is called a patina — a layer caused by the weathering chemical process you just carried out.

40. Homemade Butter

Pour heavy cream into a jar and put the lid on tight. And start shaking! This is a great one for siblings so they can take turns because it can take up to half an hour for the cream to turn to butter!

As the cream solidifies, it separates from the buttermilk. When you remove the lid, pour the buttermilk away; underneath, you’ll have butter. Spread it on your toast, and enjoy!

41. Neon Flowers

Fill up a few glasses with water and five drops of food coloring. Mix well before adding white daisies or carnations to each glass. The next day, your flowers should be bright and colorful!

42. Expanding Soap

Watch what ivory soap does when you microwave it. Submerge a bar of ivory soap into water before cutting it into quarters and placing it on a plate. Pop it in the microwave for two minutes and watch as it expands into a pile of fluff!

43. Sticky Ice

Fill a container with water and ice cubes. Lay a piece of string across the container, ensuring the string is in contact with one or some ice cubes. Sprinkle salt over the string.

One minute later, gently submerge the ice cube slightly under the water to wash the salt off. Pick up the string, and you’ll notice that the ice cube comes with it!

This is because the salt melts the ice a little, and when you wash the salt away, the ice cube refreezes, attaching the string to it.

44. Density Jar

This is what I did my 5th grade science experiment on. Learn all about density with this cool and easy experiment.

Pour some honey into a jar, followed by corn syrup, dish soap, water, oil, and alcohol. The layers of liquid will sit on top of one another rather than mixing together!

45. Soap Boat

Cut out a mini boat about one-inch long using card or paper. Fill up a large tray or container with water. Dip a cotton swab into dish soap and place a tiny amount on the back of the paper boat.

Watch as it starts zooming around the water! This works because the soap breaks the surface tension of the water and creates a force strong enough to push the paper through the liquid.

46. Dancing Sprinkles

Place plastic wrap tightly over a bowl and secure it with a rubber band. Make sure there aren’t any wrinkles.

Pour a few sprinkles over the plastic wrap. Lean closely and hum songs near the bowl. The louder or higher you sing, the different sound waves you’ll create.

You can also try placing a speaker into the bowl before you place the plastic wrap over it. Once you’ve poured on your sprinkles, play a song and watch the sprinkles boogy!

47. Eggs and Salt Water

Fill a glass full of water. Fill a second glass all the way with water and add a bunch of salt. And finally, fill a third halfway with water.

Place an egg in the plain, full glass of water and watch as it sinks. In the salty glass of water, the egg floats. Finally, add salt to the third glass of water, allowing it to dissolve slightly before placing the egg inside.

What does the egg do? It floats. But if you pour water on top of it so the glass is full, the egg stays in the middle. This is a great science lesson to teach density to kids.

48. Leakproof Bag

Fill a plastic zippable bag half full with water and seal it shut. Stab a sharp pencil through the bag until it comes out the other side. Repeat with a few more pencils. Notice how the bag doesn’t leak water when you stab the pencils through!

50. Frozen Baking Soda

Fill a freezable tray with one cup of baking soda. Add three cups of water and food coloring. Mix well.

Add some figurine toys to the mixture and freeze the mixture overnight. Start pouring vinegar into the mixture as you try and rescue the figurine toys. The vinegar will slowly break down the baking soda with a fizzing reaction until you can break free the figurines.

51. Leaf Breathing

Fill three bowls with warm water. Place one freshly picked leaf in each bowl and hold the leaf down with a small rock. After a few hours, check back, and you’ll notice little oxygen bubbles all over the leaves.

These bubbles convey the oxygen coming out of the leaves. This highlights that plants breathe! They take in carbon dioxide and transform it into oxygen, which goes back into the air we breathe.

52. Exploding Colors

Fill a tray with baking soda. Fill an ice cube tray with distilled white vinegar. Add food coloring to the vinegar. Use an eyedropper to transfer the colored vinegar to the baking soda, and watch the colors explode!

53. Floating Paperclip

When you drop a paperclip into water, it will sink because it has a bigger density than water. But with this experiment, you can make it float!

Bend a paperclip to create an “L” shape. Balance another paperclip on the bottom end of the “L” shaped paperclip.

Gently lower the paperclips into the water, sliding out the “L” shaped one from beneath the second paperclip. The second paperclip will now float!

54. Viscosity Experiment

Fill three glasses with different liquids like water, olive oil, and honey. Place a ruler over the top of the glasses with a marble balancing above each glass.

At the same time, tip the marbles into the cups and watch which one reaches the bottom first. This is a great science lesson on viscosity.

55. Plastic Milk

Create your own plastic using milk. Pour one cup of fat-free milk into a saucepan with four teaspoons of white vinegar. Stir gently to combine.

Set the heat to a high temperature. Don’t stir. After a couple of minutes, the milk will start separating.

Gently stir the solution, and the milk will form a big curd called a casing. Voila! You’ve made plastic out of milk. You can mold and cut it into anything you want.

Adults should help set the heat to a high temperature and stir the milk. Don’t leave your child unattended with this experiment.

56. Oxidation With Apples

Learn about oxidation with this fun and fruity experiment.

Get 10 plastic cups and pour ½ cup of water in all but one cup. Then add ½ teaspoon of ingredients to each water-filled cup, including vinegar, honey, salt, sugar, baking soda, and anything else you’d like to try.

With the help of an adult, cut up 10 apple slices. Place one apple slice in each solution for 10 minutes.

Remove them from the solution and wait another 10 minutes. Notice how the oxidation process varies depending on what solution the apple slice was exposed to.

57. Sunscreen Science

Using bright construction paper, fold each sheet in half and open it back up. Squeeze sunscreen onto a paper plate and use a paintbrush to draw a picture on one half of the construction paper.

On the other half of the paper, apply a spray-on sunscreen. Leave the paper outside in the sun for a few hours, ideally all day.

Notice how the sunscreen bleaches the part of the paper that doesn’t have sunscreen on it. But the sunscreen portion is protected! This is a great way to enforce the importance of sunscreen.

58. Static Electricity Hair

Teach your kids about electrons and negative vs. positive charge with this silly balloon experiment! Rub the surface of a balloon with a cloth for around one minute. Hold it slightly above your head and watch your hair move upwards towards the balloon.

59. Chicken in a Cup

Punch a hole in the bottom of a plastic cup. Attach a paperclip to the end of the ribbon and weave the other side through the hole so the paperclip is inside the cup. Dampen the dangling part of the ribbon slightly.

Hold the cup tightly in one hand and use your other hand to squeeze the ribbon and pull it down in sharp, short movements. All going well, it should make chicken noises!

60. Gummy Bear Osmosis

Pour water, coke, salt water, and white vinegar into four separate cups. Add one gummy bear into each cup and wait 24 hours. Remove the gummy bears and notice how they expand or stay the same depending on the liquid they rested in.

Weigh and measure the gummy bears before and after the experiment to track exactly how much they changed.

61. Make a Sundial

Make your own sundial to help you tell time! Start by poking a stick in the ground. If you live in the Northern Hemisphere, tilt the stick at a bit of an angle to the North. If you live in the Southern Hemisphere, angle it slightly to the South.

Every hour, take note of where the stick’s shadow is pointing on the ground. So, at 7 a.m., head outside and mark the shadow with a rock. Repeat at 8 a.m., 9 a.m., and so forth. As long as the sun is in the sky, you can use your sundial to tell the time.

62. Homemade Bouncy Balls

Combine ½ teaspoon of Borax with two tablespoons of warm water. Add a few drops of food coloring (optional). Then add one tablespoon of school glue to a separate bowl. Add glitter if you’d like.

Now add ½ teaspoon of the Borax solution into your glue, followed by one tablespoon of cornstarch. Stir well.

Once the solution has hardened, pick it up and mold it into a ball. Leave it to dry for 10 minutes. Watch it bounce!

63. Instant Ice

Fill a plastic bottle with water and place it in the freezer for two hours. Carefully remove it from the freezer.

Place a bowl or cup upside down and set an ice cube on top of it. Then, slowly pour the cold water onto the ice cube and watch instant ice form!

As an extra step, you can pour the cold water into a glass. Then hold an ice cube slightly into the water’s surface and watch as the water slowly freezes beneath it.

64. Mystery Smell

Get an adult or friend to fill up various opaque containers with different objects, such as chocolate, milk, vanilla, and other fragranced items. The children should put a blindfold on and sniff the different containers, trying to guess what is inside.

65. What Dissolves in Water?

This experiment is fantastic for learning what dissolves in water and what doesn’t. Drop some ingredients into various cups — oil, sugar, pepper, flour, and more. Then add warm water and stir.

Make it more fun by guessing beforehand which ingredients will dissolve and which won’t. Were your theories correct?

It’s essential to stay safe during your science fair projects and experiments. Here are five tips for ensuring your child is safe while they meddle with science.

• Stay nearby: Don’t leave your child unattended while they perform science experiments. Stay nearby without distractions to keep an eye on what your child tries out.
• Wear protective clothing: It’s a good idea to wear a lab coat, glasses, and goggles while conducting experiments. Many ingredients, even natural ones, can irritate the skin and eyes.
• Provide clear instructions: Before your child attempts a science experiment, ensure you have given them clear instructions, and they have a good understanding of what to do.
• Only do approved experiments: The experiments on this list have been tried and tested many times. I urge you to stick with approved experiments. Don’t make up your own experiments, as many mixtures and chemical combinations can make toxic gasses.
• Work in a well-ventilated spot: Some ingredients might cause nausea, dizziness, and headaches. So always work in a well-ventilated spot near an air purifier or open window.

What Are the Most Popular Science Experiments?

The most well-known science project experiment is definitely the baking soda and vinegar volcano. It has a beloved place in school fairs, movies, and TV shows.

Other popular projects include invisible ink, growing crystals, making a vegetable battery, making a baking soda rocket, and elephant’s toothpaste.

What Are Some Simple Science Experiments?

Your science experiment doesn’t need to be super complicated.

Keep it nice and simple with these easy experiments:

• Magic Milk.
• Black Pepper Trick.
• Dancing Raisins.
• Sink or Float.
• Eggs and Salt Water.

Watch the video below to see this fun  Rainbow Lemon Volcano Experiment in action .  Make sure to subscribe to our  YouTube channel  for more fun videos!

This rainbow lemon volcano experiment is a colorful science experiment kids can make with just a few household ingredients and smells great!

We have been loving baking soda experiments lately and this Rainbow Lemon Volcano Experiment is no exception! Unlike our Giant Baking Soda Balloon or Rainbow Baking Soda Volcano , this experiment smells really great and not all of vinegar! 

What we love about these easy science experiments for kids at home is that they requires basic household kitchen ingredients like baking soda so you can start creating and learning right away.

What do you need to make these lemon volcanoes?

The basic ingredients you need are just lemons and and baking soda! You can add colors to make them rainbow via gel colors, or you can also add additional lemon/vinegar juice to make crazier eruptions! You can also add dish soap to make it super fizzy!

What causes the baking soda volcano reaction?

Like our rainbow baking soda volcano experiment , this is experiment is an acid/base reaction. Lemon is acidic and baking soda is a base. When you mix an acid with a base, two new chemicals form, carbonic acid and sodium acetate. The new acid then decomposes into water and carbon dioxide which causes bubbling. 

What creates this lemon volcano is when you mix the lemon juices with the baking soda. We added dish soap to make it extra foamy and food coloring to make them rainbow. 

Rainbow Lemon Volcano Experiment – Materials: 

Lemons , baking soda, food coloring (we recommend  gel colors  for vibrancy instead of water base), lemon juice, a plastic bin to keep the volcano mess contained, popsicle sticks or any utensils will do.

The video will show you the process but it’s as simple as adding baking soda, food coloring  and dish soap to cut lemons! You can make it extra fizzy and create epic eruptions by adding a blend of lemon juice and vinegar. 

INSTRUCTIONS 

(Watch the video in the post)

Step 1. Cut your lemons in half. It helps to cut the tip off one end so the cut lemon stays upright. Save some halves for lemon juice.

Step 2. add your cut lemons inside a plastic bin. with the other halves not in the bin, squeeze lemon juice out of them and add to a separate container, diluted with half vinegar. set that aside for your experiment. you could use all lemon juice but we thought it was a waste of good juice so we diluted half with vinegar instead. , step 3. use a popsicle stick or any utensil to cut through the upright lemons in the bin, you just want to start releasing some juice for the experiment to work. , step 4. add a few drops of food coloring, one color per lemon, in rainbow order. , step 5. add about a tablespoon of baking soda over each lemon half., step 6. to erupt the lemons and create a volcano you can do this one of two ways. you can 1) use a popsicle stick and mix in the baking soda so it comes into contact with the lemon juice as you break it down. this results in a small volcano. you can also help it along with pouring the lemon juice/vinegar mixture on top of the lemons you can do this in a grand way as shown in the video by pouring over all lemons, or you can pour over just one and then continue to use the popsicle sticks to keep watching it foam and fizz. .

You can continue to add more gel colors, dish soap, baking soda and lemon juice/vinegar after the first eruption. Keep erupting those lemon volcanoes!

Test theories out with your kids. What happens when we add more or less of an ingredient? 

This is such a fun science experiment that smells so great as you’re creating!

Popsicle Science – Turn a Summer Snack into a Science Lesson!

Normal 0 false false false EN-US X-NONE X-NONE

juice, plastic cup, ruler, waterproof marker, popsicle stick (or plastic spoon), index card

1. Fill a small plastic cup about ½ full of juice. (Cups with the straightest sides work best.)

2. Cut a slit in the middle of an index card and place it over the cup. Insert a Popsicle stick or plastic spoon through the card and into the liquid, holding it upright with the index card.

3. Make a mark on the outside of the plastic cup at the top of the juice.

4. Measure the height from the bottom of the cup to the mark. Record.

5. Place the cup in the freezer and leave undisturbed until frozen.

6. Remove from the freezer and measure the height of the frozen juice. Record.

7. If age appropriate, calculate the change in height and record.

8. Ask the question, “Why is there more juice in the cup when it is frozen?”

How it works:

Juice contains a large amount of water. Water is one of the only substances on earth that expands when it freezes. Most liquids contract as they get colder as the molecules slow down and get closer together. Water does contract as it cools all the way down to 4 °C. But between 4°C and 0°C (the freezing point of water), the water molecules actually begin to spread farther and farther apart. Solid water (ice) is less dense than liquid water because the molecules in ice are spread farther apart than in water. That’s why ice floats in water.

How To Teach Science

Kids are curious and always looking to explore, discover, check out, and experiment to discover why things do what they do, move as they move, or change as they change! My son is now 13, and we started with simple science activities around three years of age with simple baking soda science.

Here are great tips for making science experiments enjoyable at home or in the classroom.

Safety first: Always prioritize safety. Use kid-friendly materials, supervise the experiments, and handle potentially hazardous substances yourself.

Start with simple experiments: Begin with basic experiments (find tons below) that require minimal setup and materials, gradually increasing complexity as kids gain confidence.

Use everyday items: Utilize common household items like vinegar and baking soda , food coloring, or balloons to make the experiments accessible and cost-effective.

Hands-on approach: Encourage kids to actively participate in the experiments rather than just observing. Let them touch, mix, and check out reactions up close.

Make predictions: Ask kids to predict the outcome before starting an experiment. This stimulates critical thinking and introduces the concept of hypothesis and the scientific method.

Record observations: Have a science journal or notebook where kids can record their observations, draw pictures, and write down their thoughts. Learn more about observing in science. We also have many printable science worksheets .

Theme-based experiments: Organize experiments around a theme, such as water , air , magnets , or plants . Even holidays and seasons make fun themes!

Kitchen science : Perform experiments in the kitchen, such as making ice cream using salt and ice or learning about density by layering different liquids.

Create a science lab: Set up a dedicated space for science experiments, and let kids decorate it with science-themed posters and drawings.

Outdoor experiments: Take some experiments outside to explore nature, study bugs, or learn about plants and soil.

DIY science kits: Prepare science experiment kits with labeled containers and ingredients, making it easy for kids to conduct experiments independently. Check out our DIY science list and STEM kits.

Make it a group effort: Group experiments can be more fun, allowing kids to learn together and share their excitement. Most of our science activities are classroom friendly!

Science shows or documentaries: Watch age-appropriate science shows or documentaries to introduce kids to scientific concepts entertainingly. Hello Bill Nye and the Magic Schoolbus! You can also check out National Geographic, the Discovery Channel, and NASA!

Ask open-ended questions: Encourage critical thinking by asking open-ended questions that prompt kids to think deeper about what they are experiencing.

Celebrate successes: Praise kids for their efforts and discoveries, no matter how small, to foster a positive attitude towards science and learning.

What is the Scientific Method for Kids?

The scientific method is a way scientists figure out how things work. First, they ask a question about something they want to know. Then, they research to learn what’s already known about it. After that, they make a prediction called a hypothesis.

Next comes the fun part – they test their hypothesis by doing experiments. They carefully observe what happens during the experiments and write down all the details. Learn more about variables in experiments here.

Once they finish their experiments, they look at the results and decide if their hypothesis is right or wrong. If it’s wrong, they devise a new hypothesis and try again. If it’s right, they share their findings with others. That’s how scientists learn new things and make our world better!

Go ahead and introduce the scientific method and get kids started recording their observations and making conclusions. Read more about the scientific method for kids .

Pepper and Soap Experiment

The pepper and soap experiment is one of the easiest science activities to help children understand buoyancy and surface tension. The theoretical part of science lessons can sometimes be very abstract and confusing to understand. But, performing simple Science experiments for kids like the Pepper and Soap Experiment helps children learn those difficult concepts easily.

Performing The Pepper Dish Soap Experiment

The pepper and soap experiment is one of the easiest science activities for kids and needs very few ingredients. 

Here is a step-by-step guide to performing the Pepper and Soap Experiment with your kids:

Things You’ll Need For The Pepper And Soap Experiment

Step-by-step guide to performing the pepper and soap experiment, the science behind with pepper and dish soap experiment, why should you perform the pepper and soap science experiment.

The Pepper and Soap Experiment is really simple, all you need are dish soap, water, and some black pepper. These are simple ingredients that you can easily find in your kitchen or pantry.

• Liquid dish soap
• Black Pepper
• A small bowl

Download Pepper & Soap Printable

Here is a step-by-step guide to set up and perform the pepper soap experiment with your child:

Fill the plate with water almost to the edge, but ensure that it doesn’t overflow.

Sprinkle some black pepper over the water. You’ll notice that the pepper floats on the water. This happens because of buoyancy.

Dip your finger in the center of the plate. Did you notice any change? Not much happened, right? You may have just got some pepper flakes stuck to your finger. Imagine that these pepper flakes are germs. If you accidentally touch your face or mouth with hands that are contaminated with germs, it could make you sick.

Now, add a drop or two of liquid soap into a small bowl. Ask your child to stick their finger into the bowl and get some soap on their finger.

Now, dip your soap-covered finger in the bowl with the water and pepper flakes. See anything different this time? You’ll notice that the pepper flakes (germs) move away to the edge of the plate. Your soapy finger pushed the pepper flakes away to the edge of the plate. 

This simple science experiment with pepper and dish soap is fun to watch for kids and adults. It is fun to see how the soap pushes away all the pepper flakes to the edge of the plate. Help your child understand the science behind this science experiment with pepper and dish soap.

Why do the pepper flakes float on the water?

The pepper flakes float because of buoyancy, which is the upward force exerted by a liquid. This force causes an object placed on the liquid to float.  

So, why did the pepper flakes move away to the edge of the plate?

This happens because the liquid dish soap changes the surface tension of water. 

The surface tension of a liquid is the tendency of liquid surfaces to resist an external force due to the cohesive nature of its molecules. The pepper flakes are so light, it floats on the water surface due to surface tension. The addition of soap broke the surface tension of water, but the water molecules want to keep the surface tension intact. So they pull away from the soap along with the pepper flakes. This pushes the pepper or “germs” away from your soap covered finger. This is why soap is such a great cleaning agent and so effective in cleaning dishes and taking all the grease and dirt away. 

This pepper and soap experiment also shows how germs are removed from hands with soap. The pepper flakes or “germs” were not chased away until you added soap to the bowl. 

This science experiment doesn’t just teach science concepts like surface, tension, buoyancy etc. The Pepper and Soap Experiment is also a great way to help children understand the importance of washing hands. Handwashing is a hygiene practice that all kids must learn. It keeps away germs and helps prevent several infectious diseases. 

Ever since the world was hit by Coronavirus disease, the importance of handwashing has increased tenfold. Contaminated hands can spread the Covid-19 disease easily. So, washing hands is the first line of defense against the Covid-19 disease and cannot be ignored. One needs to wash their hands for at least 20 seconds with soap, to keep the germs away. Kids are usually negligent about such stuff, teaching them to wash their hands frequently is important.

We hope you liked the Pepper and Soap Experiment. For more kids learning resources, check Osmo.

Popsicle Science

Practice observation, measurement and other skills while you learn about freezing rates of different liquids.

Cooking activities are great for teaching kids how to use measurement tools, giving them a chance to apply math skills like counting, adding, multiplying, etc. In addition, when you give them a chance to design their own recipe, kids have to rely on estimation, problem solving and other science, math and engineering skills.

Preparation

Ice cube trays come in many shapes and sizes. If you can find trays that make smaller cubes, they will be more effective for this activity—the larger the cube, the longer you’ll have to wait for it to freeze! You can buy ingredients ahead of time for the freeze test described below, or you can brainstorm a list with your kids one day, shop for what they come up with and conduct the experiment another day.

Gather lots of different kinds of drinkable liquids and other edible substances that seem appropriate (some foods like whipped cream and peanut butter seem sort of like a liquid and sort of like a solid—both are delicious). The more different kinds of ingredients you have, the better the experiment will be. Make sure that all ingredients are the same temperature—you can do this by putting them all in the refrigerator overnight before you use them, or leaving them all out at room temperature for a few hours. When you have all of your ingredients, separate them into several cups so that materials can be shared. You’ll want 2–3 cups of each ingredient.

Suggested Materials

• Ice cube trays (1 per team)
• Many different kinds of drinkable liquids or other ingredients, especially real fruit juices (ex. orange and apple juice, soda, milk, cream, peanut butter, whipped cream, vegetable oil, etc)
• Clear plastic wrap

Optional Materials

• Eyedroppers

Make it Matter

Opening discussion.

Ask your students if they have ever had popsicles before. What kinds of ingredients are in popsicles? What are their favorite flavors? Tell them that you would like them to invent their own popsicle recipes, but before they do, they need to figure out what ingredients will work best. Have them brainstorm a list of ingredients they would like to test. If you’ve chosen to do the testing right away, tell your students that before they create their recipes, they’ll be testing lots of different liquids and other ingredients to see how they freeze. If you choose to have a set of ingredients that more closely resembles their brainstorm list, tell them that you’ll need to purchase their requested ingredients and that they’ll be testing these ingredients another day.

The Challenge

Does everything freeze at the same rate, or do some substances freeze faster or slower than others? Are there some that won’t freeze at all? Test your ingredients and find out the answer!

Make it Happen

Doing the activity.

• Separate children into teams of 2 or 3.
• Have each team choose 3-6 of the ingredients you have separated into cups. These will be their testing ingredients. Since most ice cube trays have 12, 16, 36…up to 90 cubes, you should consider having teams share trays. This will save space in your freezer and will cause the freezer door to be opened and closed less frequently.
• Once teams are all settled and everyone knows which teams are sharing trays, have them fill their tray compartments with the ingredients they chose, being careful to add the same amount to each compartment. Teams will need to make a “map” of their ice cube trays, noting which liquids are where in the tray.
• Once the trays are filled, place a sheet of plastic wrap over each tray and have your students carefully poke a toothpick into each cube compartment—these toothpicks will be the “handles” of their mini popsicles. The plastic wrap helps keep the toothpicks upright. You could have each team create small flags or other markers and attach them to the toothpicks, marking what ingredient is in each cube.
• Place the trays in the freezer, and check them every 15 minutes or so. The most efficient way to accomplish this is for you to take every tray out, put them on the table and have each team record their observations.

Make it Click

Let’s talk about it.

After you’ve placed the trays in the freezer, ask your students to predict what will happen. How long will it take for the ingredients to freeze? Will some not freeze at all? Will some freeze faster or slower? Make a list of the ingredients that they predict will be “Fast Freezers”, “Slow Freezers”, and “No Freezers”.

Make it Better

Build on what they talked about.

Keep checking on the popsicles, and have your students write down their observations. While they wait, you can have them develop a recipe to test out during the next session. Tell them that they can mix ingredients up, and that they’ll also have sugar, honey and food coloring to use. What flavors might go well together?

When the cubes are all (or mostly) frozen, have your students take them out and (if you would like) taste them. What do they notice about their popsicles—do they look bigger, smaller or the same size in the tray as they did when they were just liquid? Do they taste different or the same as they did unfrozen? Will this change their choices of ingredients for their recipes?

Suggestions

• If you are using mini-ice cube trays, they will begin freezing in 15 minutes or so, and will be fully frozen in 45 minutes. Large ice cube trays take longer.
• After trying this activity, give kids a chance to create their own popsicle recipes in the Popsicle Science – Invent Your Own activity.

Rainbow Popsicle Soap – Melt and Pour Soap Recipe

Home » Blog » DIYs and Craft Projects » Rainbow Popsicle Soap – Melt and Pour Soap Recipe

• Updated: Oct 27, 2023
• Home Decor , Popular Posts , Rainbow , Soap

Learn how to make popsicle soaps with this super easy melt and pour soap recipe. You can make them into rainbow popsicles and multicolor layers.

Table of Contents

These DIY soaps would make adorable party favors and gifts, or keep them for yourself! They also make great guest soaps as a fun and whimsical surprise – especially the glittery rainbow popsicle soap. Any other rainbow craft fans?

I really like this easy craft project  because it uses a melt and pour soap base, making it a great craft for kids. Growing up, soap making was actually one of my favorite craft projects. I had my few simple soap molds and would just crank them out. I used every one of those soaps as well and always felt proud I had made them myself. If I knew then I could make soap look like desserts and treats, I don’t think I would ever stop making soaps!

Note: Some links in this post may contain affiliate links, which means at no cost to you, I may earn a commission.

Materials for Popsicle Soaps

• Clear Glycerin Soap Base
• Soap Fragrance  or Essential Oils
• Body Safe Glitter
• Popsicle Mold (yes, I use an actual popsicle mold like this one !)
• Popsicle Sticks

Video Instructions to Make the Glitter Rainbow Popsicle Soap

Step by step instructions.

Cut off some of the clear glycerin soap base into 6 microwave safe containers.  Each one will be a different color so add a few drops of a single color of soap dye into each. You want to have red, orange, yellow, green, blue and purple.  Microwave them on 10 second increments until melted and mix in some of the body safe glitter.

Tip:  If you don’t have all of those colors, that’s totally fine, you can mix the colors using red, yellow, and blue. ( Red+Blue=Purple), ( Red+Yellow=Orange), ( Blue+Yellow=Green)

Add in a drop of fragrance to each and mix in. Since you have multiple layers, you don’t want to add in too much to each.

Then starting with the red (or pink, in my case), pour the melted soap into the popsicle mold. Wait for a film to form on top and then carefully pour in the orange soap.

Tip: It’s a good idea to spray each layer of soap with rubbing alcohol before pouring on the next layer. This pops any bubbles and allows the layers to stick together more easily.

Next, pour in the yellow soap. Continue pouring in each color on top of the other so the next colors would be green, blue, and lastly, purple.

Tip: If your mixed soaps harden, you can simply eat them up again in the microwave.

After you have all of the colors in the popsicle mold, put the top on and insert a popsicle stick. Make sure the popsicle stick is at least half way down the mold.

Then place in the fridge to set and then carefully remove your rainbow popsicle soap from the mold.

You'll never be spammed and can unsubscribe at any time, how to make other tasty looking soaps.

To make the other colorful popsicle soaps, simply choose the number of colors you would like to use. Then repeat the process of layering them in the popsicle mold.

Feel free to get creative making these tasty looking soaps – mixing different colors and layers. Or keep them simple and make them a single color. You can also use other soap bases such as white glycerin, goats milk, or shea butter. These won’t be see-through so you can test out different styles.

Anything hands-on with a cool reaction — like our fizzy baking soda hearts or milk and dish soap science experiment — is always a great way to start our day and lead into bigger questions about how things work.

This week we tried an awesome  Ivory soap microwave science experiment for kids  to explore how air expands when it heats up!

You only need three things to conduct this experiment:

• microwave-safe plate
• bar of Ivory soap

While this experiment could potentially work with other brands of soap, Ivory is recommended as it is known for having extra air “whipped into” the final product. If you try it with another brand of bar soap, please let us know how it turns out!

Simply unwrap your bar of soap (a good fine motor activity) and let your child explore the soap while describing the activity that you have planned. Explain that this bar of soap has little pockets of air in it and that air expands when it is hot, and takes up less space when cold.

Ask them to hypothesize (guess) what will happen to the bar of soap if you were to put it in the microwave.

(Encourage them to support their hypothesis by linking their guesses to what they observe about the bar of soap and what they have previously observed with the microwave.)

Place the bar of soap on a microwave-safe plate and place in the microwave on high for 1-2 minutes. I personally found our soap stopped expanding after 1 minute, but microwaves can vary.

Observe the changes that the soap goes through, using as much descriptive language as possible.

Take out the plate and once the expanded soap has cooled down, allow your child to carefully explore it (keep in mind that while the outside of the soap may be cool, it could still be very hot towards the center. I would suggest exploring using “tools” rather than fingers.

Ask your children to interpret or make sense of what they have observed and draw conclusions .

This easy and safe science experiment for kids is such a great way to introduce learning about weather or discussing how microwaves work. (And practice going through the steps of the scientific process.)

You can then use your soap to make homemade laundry detergent , or clean mud with the kids !

Would you try this science experiment with your kids? What other science experiments for kids have you tried?

Looks like fun! I think it would be fun to expand this experiment and try other brands of soap, recording the results. I’m definitely going to keep this one in mind for when we need something to do this summer.

Ooh, let me know if you do it! I’ve been curious to try but I’m happy to let someone else do the experimenting 😉 LOL

What an awesome experiment it is. My children will love it a lot, for sure. Thank you for sharing.

That’s so awesome to hear – I hope they have a blast!

I did this experiment, & its so much fun.

Stay-at-home science project: Two-ingredient Silly Putty

By Purbita Saha

Posted on May 6, 2020 4:00 PM EDT

Welcome to PopSci ’s at-home science projects series . On weekdays at noon, we’ll be posting new projects that use ingredients you can buy at the grocery store. Show us how it went by tagging your project on social media using #popsciprojects.

Silly Putty is a toy most anyone can appreciate . Pinch it, bounce it, stretch it, slap it on the side of your face—it does whatever you want it to do, with little complaint.

But the chemical properties that make Silly Putty so bendy and durable are shockingly complex, as are its ingredients. The list is long and includes tongue twister-like names like polydimethylsiloxane and boric acid. Sounds tough to replicate at home. Or is it?

This experiment lets you turn two common goods (cornstarch and dish soap) into endless hours of non-Newtonian fun .

• Time: 5 minutes
• Difficult: easy

What you’ll need

• ⅔ cup of cornstarch
• ½ cup of dish soap
• Small container or bowl
• Food dye (optional)

Instructions

1. Pour the cornstarch and dish soap into a container. Add a few drops of water to help the goop bind, then fold it all together with a spoon.

• Note: Your putty will have a slight hint of color if you choose dish soap that’s green, yellow, or another hue.

2. Mold the putty with your hands until most of the starch and soap is used up. If the mixture is too dry and crumbly, squeeze in some extra soap. If the mixture is too liquid, sprinkle in some more starch.

3. Play with it. When you’re done, store it in a cool, dark place until you’re ready to mess with it again.

How it works

In terms of chemistry, dish soap and cornstarch are perfect partners; they’re like a couple that hits it off after the first blind date. Dish soap is a surfactant, meaning its molecules have polar opposite ends —a positively charged head and a negatively charged tail. This causes it to stick to compounds such as oil and link up with the long carbon chains found in cornstarch, says Keisha Walters, a polymers scientist at the University of Oklahoma. (Flour, she explains, is way more processed, so if you substitute it for starch in this experiment, the putty will fall apart.) With a little water to help fire up the bonding process, the soap and starch form a sometimes-liquid, sometimes-solid that consistently snaps back to its shape.

Besides dish soap, surfactants are found in a number of things you eat, drink, and put on your body. “They help us stabilize orange juices and non-dairy milks so that the foods don’t separate into liquids and gross oils,” Walters says.” They’re in our ice cream and condiments, and our cosmetics and toothpaste.”

If you’re still scratching your head over this chemical reaction, Walters suggests testing out some other non-toxic mixtures. “The understanding deepens as you play more.” So go ahead—try as many twists on Silly Putty as you want. It was made to stretch your imagination anyway.
