8th grade science fair projects tend to involve the scientific method and designing an experiment and not making models or explaining processes. You'll be expected to present data in the form of tables and graphs. Typed reports and posters are the norm (sorry, no handwritten text). You should do the project yourself, rather than enlist heavy-duty help from a parent or older student. It's appropriate to cite references for any information that isn't common knowledge or that draws on the work of others.

Science Fair Projects for 8th Grade

Jan 9, 2024 / By Katherine Rea

Spark scientific curiosity with these science fair projects for 8th grade that make learning about STEM (Science, Technology, Engineering & Math) fun! Our team of researchers and scientists have developed easy-to-follow experiments that help older kids explore chemistry, physics, and tons of other scientific topics.

The best science fair projects for 8th grade begin with a hypothesis -- a supposition or proposed explanation made with limited evidence as a starting point for further investigation. Below, we've included examples of science projects to which you can apply hypotheses. To make a truly awesome science fair project, make these your own and consider how you can explore the science behind these cool demonstrations.

Don’t want the learning to stop? Check out our line of engineering kits that are perfect for 8th grade students.

Electromagnetic Train

Did you know that electricity and magnetism are closely linked? In this project, experiment with the interplay between the two by building your own miniature electromagnetic train that zips down a track all by itself.

An electric current creates a magnetic field. In fact, a coil of wire like you made here creates a magnetic field very similar to the magnetic field of a plain old bar magnet. Now, the neodymium magnets have their own magnetic field, and they’re sitting right in the middle of the wire’s magnetic field. And just like a couple of fridge magnets, those magnetic fields interact with each other. That’s where the push that propels your train comes from. The neodymium magnets get pushed along by the magnetic field of the coil of wire.

Carbon Sugar Snake

Make a fiery black snake rise from the ground with this exciting experiment! Using simple household ingredients, learn how a burning mixture of baking soda and sugar can create a stunning carbon snake.

Your carbon sugar snake is the product of three chemical reactions that are all dependent on heat. The first of these reactions occurs when sugar combusts (burns) in the presence of oxygen. This produces carbon dioxide gas and water vapor (also a gas), which pushes more of the sugar/baking soda mixture upwards. Some of this additional sugar heats up but doesn’t have access to any oxygen, so instead of burning, it undergoes thermal decomposition, producing solid carbon and more water vapor. This solid carbon now gives the snake some shape, and also gives the snake its black color. Lastly, the baking soda also decomposes in the heat, producing solid sodium carbonate, and carbon dioxide gas and water vapor. Altogether, these three reactions produce both the solid components of the snake (carbon and sodium carbonate) and hot gases (CO2 and water vapor) that expand and inflate the snake up and out of the sand bowl. The sand in this experiment doesn’t chemically react with anything in the growing snake. Instead, it evenly distributes the heat from the burning lighter fluid to the sugar and the baking soda, ensuring a slow, steady burn and the growth of a long carbon sugar snake.

Dancing Salt

Discover how music creates vibrations you can see using salt and a portable speaker! Then try experimenting with different genres of music to see which ones make the salt dance more.

Speakers, like your bluetooth speaker, produce sound by creating vibrations in the air. Normally, we only hear these vibrations, and we can’t easily see them. Plastic wrap, though, is lightweight and thin enough to vibrate in response to the sounds coming from the speakers. These vibrations move through the plastic wrap unevenly, pushing and shoving the salt around in interesting patterns. As a song progresses, these vibrations change, and the salt moves as if it were dancing. If you can find a YouTube video of a pure tone (like a single, sustained note), observe what happens to the salt when you play that tone through the speakers. A pure tone will create a consistent, unchanging vibration in the plastic wrap. Instead of dancing around, the salt should collect in places in the plastic wrap that aren’t vibrating, making patterns that depend on the frequency of the pure tone. Try a few other pure tones, one at a time, to see some other interesting patterns!

Penny Battery

Learn about electrochemical cells and make a battery using pennies, felt, and a salt water solution. Then, power a digital clock with it!

Things start up when the zinc begins dissolving into the salt water solution. That chemical reaction leaves behind some extra electrons in the undissolved zinc metal. Those electrons could be used to make electrical power if they had somewhere to go to, since electricity is just moving electrons. On the other side of the salt water, the copper reacts by giving some of its extra electrons to the hydrogen in the water. So the zinc side is producing electrons, the copper side is getting rid of electrons… what would happen if you connected them? The electrifying answer is — you get electricity! Electrons zoom from the zinc side over to the copper side, powering any electrical things they pass through along the way. A single set of these two metals and their electrolytic solution is called a “cell.” Sandwich a bunch of cells together, and you get more electrical power from more electrons moving around. The pile of cells you’re about to make—called a “Voltaic pile” after the scientist who invented them, Alessandro Volta—is the basis for the batteries you use every day.

Plant Light Maze

Have you ever noticed how plants grow toward the light? Build this simple light maze, and watch the plant grow around the obstacles to reach the light!

Try experimenting with different mazes and see how the plant reacts. Plants grow toward the light as a way of generating more energy through photosynthesis. So how do the plants grow toward the light? Plants contain a hormone called auxin, which causes plant cells to grow longer. Plant cells on the shady side of a plant contains more auxin hormones, making the plant bend toward the light as the cells in the shade elongate.

Paper Airplane Launcher

Take your paper airplanes to new heights by making a motorized launcher for them. This project could be turned into a cool experiment by adjusting the launcher's trajectory, speed, or even the shape of the paper airplane. Would the plane go further if the launcher's trajectory was raised? Questions like this could become a hypothesis for an experiment!

The Big List of Science Fair Project Ideas, Resources, and More

Options for every age, interest, and skill level!

Science fairs are a rite of passage and something many kids either dread or adore. Whatever the case, there’s no doubt these projects give students a chance to develop all sorts of skills: critical thinking, presentation and public speaking, research and writing, and so much more. Make this year’s fair the best one ever with this huge list of science fair project ideas for every kind of student.

Tips for Choosing a Science Fair Project

With thousands of possible projects, it can be difficult to narrow down something that’s a good fit for every student. Try these tips to help them find the right science fair project ideas.

Match Your Project to Your Interests

This seems obvious, but it’s really helpful for kids who feel overwhelmed by all the choices. It’s also a good way to get reluctant learners more excited about science fair projects. Encourage students to think about what they love to do in their spare time. How can they turn that into a project?

For instance, kids who love sports might explore the most effective stretches for warming up, or methods for throwing a football farther and more accurately. Music lovers can learn how sound waves work, or discover the link between music and emotions. It’s all about starting with something you love.

Challenge Yourself, But Keep It Realistic

Science fair projects need to be something kids can complete by themselves or with adults in support roles only. If a student picks something that’s way beyond their skill level, chances are the parents will wind up doing most of it. That being said, the point of the project is to learn and grow. Aim to learn something new, whether it’s knowledge or skills, by setting measurable goals.

If You Want To Win, Be Innovative

For science fair contests with prizes, the more creative you can be, the better. Projects that address real-world problems with new and interesting solutions often catch the judges’ eye. Be sure to be thorough in your research, and be ready to answer questions about your methods and results. Scientists love asking questions!

The Best 8th Grade Science Fair Projects

Oscar Pedroso October 1, 2020 STEM Projects

8th Grade Science Fair Projects – Don’t make it harder than it has to be!

It’s happened. Your eighth-grader brought home an assignment that can strike fear into the hearts of parents everywhere. It’s true. The science fair is upon us. The teacher has given them a lengthy rubric outlining all the requirements and presentation methods their assignment must adhere to. The scope of the project is enough to make your head spin if this isn’t something you’ve already done with them in 7th grade. The hardest part for most middle-school students is selecting age-appropriate science experiments that can be completed independently.

Hark! Fear not brave parents, for choosing an 8th-grade science project doesn’t need to be scary or overly complicated. Your rookie scientist just needs to find a question (hypothesis) that they really want to answer. Being interested in the outcome (conclusion) of their own project is an important part of getting them to do the work willingly rather than begrudgingly.

Check out some of the best 8th-grade science fair projects we’ve found to get your budding researcher’s wheels moving! (And don’t forget your trusty lab notebook to record methods and observations!):

1. How Does Stress Affect Body Temperature?

Thermometer

How it’s done:

This project could illustrate why your student literally sweats that math test every week. Have your volunteers perform a timed math test or a series of difficult puzzles. Take their temperature before and immediately after the high-stress activity, record, and compare! Did your volunteers stay cool under pressure? How did stress affect their temperature regulation ?

2. Which Beverages Release the Most Gas?

Baking Soda
Heating Pad
Bottles with narrow necks

A glass of milk and a glass of juice sit on a table next to a spoon.

When is a balloon actually a belch? In this project of course! Pour equal amounts of different beverages into individual bottles and add vinegar (to act like our stomach acids). Placing the bottles on a heating pad will speed up this “mock digestion”. One of the properties of gas states that gases expand to fill their container. Expanding gases will inflate the balloons that have been stretched over the opening of the bottle, visually illustrating which beverage releases the most gas !

3. What Effects Do Carbonated Drinks Have on Meat?

3 types of meat (i.e. steak, chicken, salmon)
3 containers
6 cans of carbonated soda

A small pile of cubes of raw meat on a cutting board.

Did you know soda has a similar pH level to the human stomach? So soda should be able to digest meat as our stomachs do, right? To test this hypothesis, place each different meat into a container and cover it completely with soda. Observe the meat over several days. Record observations. Students can even weigh the meat before/after the experiment to include quantitative data along with their visual observations. Read more about why this science project works the way it does!

4. Create an Optical Illusion With an Infinity Mirror

Cardboard box
Mirror (same shape as the container)
Mirrored window cling
LED Christmas lights
A sheet of plexiglass or acrylic
Cutting tool

Two bathroom mirrors make what appears to be a never ending reflection of each other, similar to the effects of an infinity mirror.

Mirror, mirror on the wall – Are you a mirror or a never-ending hall? Your student will create an optical illusion with some inexpensive and basic supplies. Use adhesive to secure the mirror to the floor of the box. LED bulbs are inserted through holes in the walls of the box. The visual trickery lies in the mirrored window cling viewing window. Check out this optical illusion in greater detail!

5. Can We Distill Saltwater With Solar Power?

2 plastic containers
25 mL graduated cylinder
800 mL beaker
Modeling Clay
2 5mL funnels
Flexible straws
Steel washers
Rubber bands
Plastic Wrap

Droplets of water that appear to be evaporation or condensation are gathered and sliding down a smooth surface.

When ocean water evaporates, the salt is left behind. Collect this desalinated water with a simple DIY contraption. Containers of saltwater placed in the sunshine will begin to evaporate. Cling wrap will cover the containers to collect evaporation. Use the heavy washers on top of the cling wrap to guide droplets of evaporated water down a gentle slope into the funnel. The funnel and straw will empty into a waiting cup. Cover the cup so no freshwater evaporates! Check out a detailed assembly of the water distiller !

6. Are Our Fingerprints Inherited?

Paper Towel
Tracing paper
White paper
Magnifying glass
Volunteers – 15 pairs of siblings, 15 pairs of unrelated individuals

Volunteers can touch tracing paper that’s been heavily scribbled on with pencil. Place the index finger onto the sticky side of a piece of tape. That piece of tape now holds a clear fingerprint! Using the magnifying glass, compare the fingerprints of siblings and non-related volunteers and record. Are they the same pattern? Read up on fingerprints to feel like a real detective!

7. Owl Pellet Fossil Reconstruction

Owl Pellet (available online)
Clean paper
Tweezers, needles, and/or wooden probes to deconstruct pellet
Owl Pellet Bone Chart
Small papers to separate bones and waste between

An in-tact owl pellet lies on a wooden surface, with a second own pellet in the background.

Owl pellets (think cat hairball) hold evidence of an owl’s most recent meal. Gently use tweezers, needles, or wooden probes to separate the owl pellet into four quarters. Carefully pick the quarters apart, and set aside the animal bones on a separate sheet of paper. Think of it like a treasure hunt – a really gross treasure hunt. Use a bone chart to reconstruct and identify the animal found in the pellet.

8. How Does Color Affect Heating? A Look at Light Absorption

6-8 identical glass jars
6-8 pieces of colored construction paper
Timer or clock
Drill for making holes in jar lids

A circular array of multi-colored paper.

Wrap each jar with construction paper. Fill each jar with equal amounts of room temperature water. Take an initial temperature reading, and then another after each jar has been sitting beneath the heat source for an amount of time (i.e. – 30 minutes). Record your observations, and decide if there is a particular color that absorbed more light/heat! Read about the science behind this project in depth.

9. Homemade Hand Warmers

Jelly crystals
Iron Fillings
Calcium Chloride
Zipper-Lock Bag

A woman wearing warm clothes appears to be blowing on her hands to warm them.

You may find yourself repeating this project for a cold night of trick-or-treating or winter caroling. Fill the small cup with water and ¼ tsp. of the jelly crystals. Allow time for water absorption. Add iron fillings and Calcium Chloride to the bag. Manipulate the bag to mix ingredients. Feel the heat! You can add numerical data to this experiment by taking the temperature of the polymer beads throughout the experiment.

10. What Makes a Diaper Absorb Moisture?

New baby diaper
Zipper-lock bag
Small plastic cup

This image shows the lower half of a baby wearing only a diaper, slightly covered by a baby blanket.

It’s probably been a while since you had diapers in your house if you’re helping your 8th grader with homework. You can use scissors to open the diaper. You’ll collect polymer powder from the diaper’s stuffing into a cup. Pour water over and watch as the polymer gels. You can increase the research level of this project by comparing diaper brands and measuring the water quantities each diaper can hold.

11. What Door Handle in the School Holds the Most Bacteria?

Bacteria growing kit (Petri dishes with agar)
Sterile cotton swabs

A blue gloved hand holds up a petri dish that is rife with bacteria and growth.

Try to talk your kid out of wearing gloves to school for the rest of the year after completing this project . Using sterile swabs, sample 5 dirty doorknobs at the middle school. Rub the swab in the petri dish, cover, label, and date. Get ready to be grossed out. Observe the Petri dishes over the next few days and keep detailed records of the growth. Which door handle hid the most bacteria?

12. Why Do We Need Tendons? Engineering a Bionic Hand

¾ inch dowel rod
1-inch X 4-inch pine plank
5 bags of small screw eyes (eyelets)
2 rolls of nylon string
Wide rubber bands
1 open eyelet
White spray paint
¾ inch sheetrock screws (x2)
Basic power tools used under close adult supervision (grinder, jig saw drill press)

A white robotic hand reaches out to touch the tip of the index finger of a genuine human hand over a yellow background.

This experiment will make your child feel like Tony Stark, and teach them a bit about human anatomy. You’ll cut and grind dowel rods to make mock “bone segments”. Eyelets are inserted into bone segments where “tendons” and “ligaments” (string) will attach. Spray paint all the bone segments white, for an authentic skeleton look. The pine plank makes up the palm/wrist area. Assembling this bionic hand will earn you a high five from your teacher.

13. Which Mouthwash is Most Effective at Killing Bacteria?

Multiple brands of mouthwash
Petri dishes with agar for growing bacteria
Sterile swabs

A young lady with her mouth open wide and her tongue sticking out.

We predict your child will better about dental hygiene after this science project. Swab the inside of your student’s mouth a couple of hours after eating, and apply the sample to the petri dish. Use the mouthwash according to the label, rinse with water, then take a second sample with a new swab. Be sure to label each dish carefully. Repeat for each mouthwash type and compare bacterial growth. Try not to be grossed out, and determine which brand of mouthwash works the best!

14. Can Caffeine Make Us Faster Typists?

Caffeinated beverage
A decaffeinated beverage (soda or coffee)
Word Processing Program
Test Subjects

This is an image of a computer keyboard, a watch, a planner, and a cup of coffee, along with a pair of hands. The left hand on the keyboard, the right hand gripping the coffee.

Volunteers will type: “The quick brown fox jumped over the lazy dog.” as many times as possible in one minute after ingesting a non-caffeinated beverage. Repeat the timed typing exercise after a decaffeinated beverage. Keep your volunteers in the dark about which beverage is caffeinated!

Editor’s note: Let us know how this project works out – We might need to install a new coffee machine in the office for faster blog posting!

15. Can we see sound?

Uncooked rice
Plastic wrap
Sound source (Speaker, Pots and Pans, etc)

Grains of white rice lay in a pile on a white surface.

When your teenager blasts their music, it can feel like they’re banging on your brain! Show them how those sound waves look . This project lets us visually see the movement of grains of rice created by sound waves from loud noise nearby. You can use pots and pans or a stereo speaker as a sound source.

16. Investigating the effects of external stimuli on carnivorous plant digestion

3 Dionaea muscipula of similar size
Small crickets (available at any pet store)
3 temperature controlled locations
Thermometers

A Venus Fly Trap plant with multiple "mouths".

Plants straight out of a science fiction movie are enough to make any student interested in this project! You’ll look at external stimuli effects on the digestion time of the Venus flytrap. Plants are placed in locations where temperatures can be monitored and controlled. “Feed” the plant a cricket. After the plant snaps shut, monitor how many days each plant spends digesting the insects. Do warmer temperatures speed up digestion? Make sure your student doesn’t try to feed their little brother to the plant.

17. Determining the Iodide content of different types of salt.

Plastic cups
100mL graduated cylinder
Distilled water
Laundry starch solution
Iodine antiseptic solution
Medicine dropper
5 types of salt
Hydrogen peroxide solution

Tell your eighth grader there’s no reason for them to be ‘salty’ about a little hard work. This project is inexpensive and has a short observation. First, create a solution of distilled water, laundry starch, and iodine. Stir and set aside. Mix salt and distilled water and stir. Add 15mL of vinegar, then 15 mL of hydrogen peroxide. Add 2.5 mL of the starch solution you set aside. Repeat these steps with each salt. What colors are you seeing?

18. What material blocks UV light most efficiently?

UV reactive beads (available at most craft stores or online)
Ultraviolet lightbulb (or a sunny day)
Sunglasses, UV protecting clothing,sunglasses, sunblock, umbrella

This image is a large collection of white beads, which is what UV sensitive beads look like prior to exposure to sunlight.

This project will have your teenager arguing a little less about wearing sunblock on the next family vacation. UV reactive beads change from white to vibrant colors when exposed to UV light. You can coat the beads with sunblock, place them under sunglasses or UV protectant clothing, and compare the color changes. You can compare sunscreen brands or SPF levels with this project. Check out these UV sensitive beads in action.

19. How much electromagnetic radiation is emitted during cell phone use?

Working cell phone
Measuring tape
Radio frequency meter

A hand with painted fingernails prepares to tap a touchscreen <mark><mark><mark><mark><mark><mark>cell phone</mark></mark></mark></mark></mark></mark>.

Is your teen obsessed with their cell phone? This experiment may make them hesitate to send that next text! Use the radio frequency meter to test the electromagnetic radiation power emitted from all sides of the phone when a call is coming in, as well as when a text message is coming in. Record the data, and analyze when complete. Does the amount of power differ when calling or texting? Does it decrease with distance?

20. What makes ice melt fastest?

Ice cubes – same shape and size
Glass bowls
Calcium chloride (available at local hardware stores)

A glass of melting ice rests upon a stack of books.

Is your science fair student old enough to shovel the walk this winter? They could use this experiment to go the extra mile in de-icing the walk to the mailbox. Place the same number of ice cubes into separate bowls. Apply each melting material to the ice. Observe the melting ice. Which bowl melts first? Record your results in your lab notebook. Repeat the experiment several times for accurate results.

21. Engineering earthquake-safe skyscrapers – Which design is the most stable

Lego bricks
10X10 lego base plate
Rubber balls
Smartphone and Google’s free science journal app (It has an accelerometer feature.)

An assortment of multicolored legos fills this image.

Are you an architect? See if your structure designs can withstand the seismic activity of your shake-table. Sandwiching four rubber balls between two sheets of plexiglass with rubber bands forms the base of a shake table that acts like an earthquake.

Spit it back into the paper cup and pour a bit into the test tube. You’ll add a couple drops of liquid dish soap, some isopropyl alcohol, and voila! A milky white thread of DNA appears suspended in the test tube, ready to be wound around a wooden skewer. You can freeze it in a vial for indefinite preservation!

23. Which soil type is most fertile for seed growth?

4-6 different soil types
Easy-to-grow-seeds like beans
Small pots or jars
Paper towels
Plastic bag

A garden trowel filled with dark soil is spilling some to the ground. Flowers can be seen in the background.

This project is simple and inexpensive but may take a few weeks to track. Start seeds in a ziplock bag between layers of damp paper towels. Transfer seeds carefully to jars of soil. Be sure to water them equally, and place them in a location where they have access to even amounts of sunlight. Track and record plant height and appearance over several weeks and compare.

24. Create your own pH level test strips.

Food processor
Red cabbage
Pot and burner
Isopropyl Alcohol
Coffee Filters

A head of purple cabbage sliced in half.

Creating their own testing supplies ups your scientist from rookie to novice! Add chopped red cabbage and boiling water to a food processor. Give it a good whir, and then strain the mixture. In a bowl, combine cabbage mixture and alcohol. Dip the coffee filters into the solution and soak them. Remove them to dry. Cut dry filters into strips and store in a dry place for use in awesome future science projects!

This project shows your child how important vegetation is to keep the shape of our landscapes. This is a great experiment if heavy rains are a part of your everyday landscape. Create three different soil situations inside the two liters. Pouring water through the two liters and into a waiting catch basin shows us how much soil erodes with water/rain, and how plants offer some protection from erosion.

26. Do breath mints actually cool your mouth?

Strong breath mints
250 mL beaker
Bottled water

The cool, minty feeling of a breath mint can’t just be an illusion, right? Test the theory ! Add breath mints to room temperature water. Stir gently for ten seconds. Take the temperature of the water every 30 seconds for four minutes. Record and compare the temperatures. Is it really cooling your mouth? You could offer the judges at the science fair a breath mint during your cool science presentation!

27. What is leaf chromatography?

Soft, fresh, green leaves (spinach will work)
Food processor (or mortar and pestle)

You’ll be amazed at the different colored pigments hiding in a green leaf. Grind your green leaves into a pulp. Add some isopropyl alcohol to cover the pulp. Dip the coffee filter strip in until just the end touches the liquid. As colors climb the coffee filter, they’ll separate. Wait until the liquid has climbed to the top, then remove. You can analyze and even identify the types of pigments on the strip such as chlorophyll, carotenoids, and xanthophylls .

28. Which plants can resist the poison of a Black Walnut Tree?

Radish seeds

Crafting a Winning Science Fair Project

Once you have picked your project, you might be wondering how to make it the best Science Fair Project. Here are a few of our best tips, but if you need more more guidance visit our resource on Elementary Science Fair Projects or our Guide to the Science Fair .

The Question

Every great Science Fair Project begins with a question that piques your curiosity. Choose something you’re genuinely interested in exploring.

Research Thoroughly

Go beyond Google, you need to dig in and really research your topic. Go to the library, contact professional organizations, and talk to experts in the field. Well conducted research may open up even more exciting and innovative approaches you can take with your idea. Make sure you understand the science behind your project. The more you know, the better you can design your experiment and interpret your results.

Make a Plan and Document Meticulously

Just like you would make an outline for an essay, spend time creating a plan for your project. Then make sure you detail every step of your experiment. Be meticulous in your approach. Ensure you record all the steps, every part of your process, and your findings accurately.

Think Outside the Box

Innovation is key. Don’t be afraid to try something new or take a different approach to a common problem. Remember all that research you did, get creative and see what you can bring to the research from your unique perspective. Maybe you can solve a problem and become a changemaker!

Focus on the Presentation

How you communicate your findings is just as important as the experiment itself. Create clear, concise displays and practice explaining your project in a way that’s both engaging and informative. One tip I love is to video tape yourself doing your presentation. This can help you fine tune until it is perfection.

This reminds me… proof! Make sure you have proofed everything numerous times for any errors. Get someone you trust to also proof your materials to ensure they are mistake free. This includes your report, displays and any other materials you create to go with your project.

Anticipate Questions

You are the expert on your project. Be ready to answer questions about your methodology, findings, and the implications of your investigations. The better you understand your work, the more confidently you can discuss it. My tip is to get your family or friends to watch your presentation and ask questions. You can even send the video of your presentation to get their feedback to help you prepare for those questions.

The 8th grade science fair is more than just a bunch of experiments, it’s a platform where young minds learn to question, explore, and innovate. By embracing the challenges and opportunities it presents, students not only gain valuable scientific knowledge but also develop skills in critical thinking and problem-solving that will serve them well in their future academic and professional careers. Most of all, use this as an opportunity to develop those passion projects, foster a love of learning, and embrace curiosity!

A science fair in school is an excellent avenue to showcase your talent in subjects that interest you. What’s more, it also earns you good grades. You can experiment with some cool science projects that not only show your scientific inclination, but also your creativity.

As an 8th grader, you are expected to come up with something that’s fun, easy to demonstrate, and imparts knowledge. You can come up with some tried-and-tested ideas and represent them in a unique manner. Do not try to go for something complicated which requires too many theoretical details to be explained.

You need to make sure your project is attractive enough, without being too flashy, which shifts the focus away from your information. You can choose a simple, well-focused experiment or project that you can explain to your friends, visitors and more importantly, the judges.

Environmental Projects

Ideally, students never face a dearth of environmental issues to create awareness about, considering the manner in which we are plundering our natural resources. You could create a model of a volcano, or perhaps explain how tsunamis occur.

Alternatively, you can always research various renewable sources that provide us with clean energy. Another interesting idea is where you showcase the environmental damage we are causing by making a futuristic model of your town.

Project Examples :

Volcano Model
Clean Energy Sources
Futuristic Town

Physics Projects

Physics projects may be a little tougher to make, but they rank really high on the creativity factor. Here, we suggest making a simple microscope, or coming up with a list of heat retentive materials, with an explanation of how they function.

As a demonstrative project, you can present a model explaining Newton’s laws of motion. Among other ideas, you can make presentations on the working of different electrical appliances like microwaves, steam irons, televisions, induction stoves, etc.

Simple Microscope,
Newton’s Laws of Motion
Heat Retentive Materials

Chemistry Projects

With chemistry as the subject, there are plenty of options to choose a project topic from. You can create a presentation on the side effects of various chemicals in medicines, household products, or cosmetics. Conducting a study on the crystalline structure of salt could be an interesting option. Studying the viscosity of various liquids can make a good project. Another offbeat idea is to study the importance of chemicals in forensic science.

Side-effects of Medicines
Chemicals in Cosmetics
Crystalline Structure of Salt

Biology Projects

With biology as your subject of choice, you have a long list of options, from evolution to marine biomes/terrestrial biomes, to the food chain. Make your presentation as unique as possible, with the wide range of topics available. You can come up with a study on the various viruses that cause illness in human beings and other animals, for instance, regular flu, swine flu, or bird flu. Try making a presentation on sexual/asexual reproduction in plants.

Marine Biome
Eating Healthy

Animal World Projects

The animal kingdom provides an exhaustive list of topics. For starters, you can come up with a comparative analysis of dominant against weak senses present in dogs and cats. You could also study the level of aggression between dogs and cats, or their hunting instincts. If you don’t have these pets, there are plenty of other topics to choose from. Animal conservation is a hot topic of debate around the world, and you can study the impact of animal extinction on the environment.

Cat’s Senses V. Dog’s Senses
Consequences of Whaling
Interaction Between Animals

Astronomy Projects

If you’ve seen a meteorite shower, or know about comets that visit our skies, you can come up with a unique presentation on their formation, and their journey through space. If you are interested in watching the night sky, you can try spotting a constellation, and make a model of it. Studying the birth and death of a star is an interesting topic too. Asteroids and planetoids, that orbit the area between Mars and Jupiter can make a good project topic as well.

Evolution of the Sun

Finally, ensure that you clear the concepts and theories behind the project idea you’ve chosen. Once you understand the fundamentals of the experiment or project, you will be able to explain it well. You may need assistance from an adult in some science project ideas, so ask your parents, teachers or elder siblings for guidance. With all the efforts you’ll be taking, don’t forget to have fun, as it remains the most important aspect of learning.

Hypothesis: Predict what will happen when you mix baking soda, vinegar, and a few other ingredients in your model volcano. Do you think it will erupt like a real volcano?

Place the plastic bottle on the tray. This is your volcano’s “magma chamber.”
Use the modeling clay or playdough to shape a mountain around the bottle. Leave the top open so you can add your ingredients.
Get creative with the shape and details of your volcano!
In a separate cup, mix together 200 ml of vinegar, 5 ml of dish soap, and a few drops of red food coloring to create your “lava.” This will help make the eruption more colorful and bubbly.
Pour the vinegar mixture into the bottle in your volcano.
Add 60 grams of baking soda to the bottle and quickly step back to watch your volcano erupt!

Observation: Watch closely what happens when the baking soda meets the vinegar mixture. You should see a foamy and fizzy eruption that looks like lava flowing down the sides of your volcano.

Results: Record what you observed. Was the eruption slow and steady, or quick and explosive? How high did the “lava” flow?

Conclusion: Explain why the reaction happened using simple science. When baking soda (a base) and vinegar (an acid) mix, they create carbon dioxide gas, which builds up pressure until it forces the liquid out in an eruption. This is similar to what happens in a real volcano, where gases build up pressure underground.

Further Experimentation:

Try the experiment again using different amounts of vinegar or baking soda. Does changing the amounts change how your volcano erupts?

This experiment not only teaches you about chemical reactions but also lets you create a mini spectacle at home or at your science fair. Have fun being a young scientist and remember to clean up after your experiment!

2. Floating Egg Experiment

Introduction: Dive into the fascinating world of density with the Floating Egg Experiment! This simple yet intriguing project is perfect for first and second graders to explore how different solutions affect whether an object sinks or floats. This experiment will need a bit of adult help, so make sure you have a grown-up to assist you!

Objective: To understand how the addition of salt to water changes its density and affects the buoyancy of an egg.

Tap water (about 500 ml)
Table salt (about 60 grams)
1 large clear glass or jar
Measuring spoons
Stirring spoon

Hypothesis: Before you begin, think about whether you believe the egg will float in plain water and what might happen when you add salt to the water. Write down your guess.

Fill the glass or jar with 500 ml of tap water.
Gently place the raw egg into the glass of plain water and observe what happens. Does it sink or float?
Remove the egg carefully.
Add 60 grams of salt to the water. Stir well until the salt is completely dissolved.
Once the salt is dissolved, gently place the egg back into the saltwater solution. Observe what happens this time.

Observation: Note down what you see. How does the egg behave in plain water compared to the saltwater?

Results: Record your findings. Did the egg float in the saltwater? Was there a difference in how it behaved in the plain water compared to the saltwater?

Conclusion: Explain why the results occurred based on density. In plain water, the egg sinks because its density is higher than that of plain water. When you add salt to the water, it increases the water’s density, making it denser than the egg, which now floats.

You can experiment further by changing the amount of salt added to the water or trying different liquids like sugar water. See how these changes affect the egg’s buoyancy.

This experiment not only teaches you about the principles of density and buoyancy but also shows you how different solutions can change the behavior of objects in water. Have fun experimenting, and remember to ask questions and think about why things happen the way they do!
