30+ Science Fair Projects That Will Wow The Crowd

February 20, 2022 by Ana Dziengel Leave a Comment

Are your children signing up for the science fair this year? Have you begun the arduous task of looking for  science fair projects  that might pique your child’s interest? Or do you have a child who already has ten ideas they have been dying to try?

The science fair is a great school tradition and a memorable experience for many children (I still remember the life size plaster penguin I made in 5th grade), and if your school doesn’t conduct one, consider starting it!

This year if you are on the lookout for science fair projects I challenge you to think beyond the vinegar volcano (we have “Volcano Alley” at our school because there are so many volcano projects every year). I know, vinegar volcanoes are like a rite of childhood passage, but there are so many other amazing science ideas out there! I have compiled a list of 30+ science fair projects for kids based on their grade level below. Before we get started I wanted to share some tips for getting the most out of the science fair.

This post contains affiliate links.

Science Fair Tips

• Don’t do the project for your child! This is my number one tip. Many parents have a tendency to jump in and make children’s work “more presentable” or to assist their child so much in the project that it’s hard to know who actually did it. Listen I get it, science is fun and you want your child to have a wonderful presentation…but that’s not really what the science fair is about. It’s about your child learning how to do scientific research and present their findings in their own way. Think of yourself as a helpful guide NOT an assistant, and definitely not the boss.
• Choose something age  appropriate  When your child is choosing the science fair idea they want to try, make sure it’s age appropriate. Sure we’d all love to make a working robot but there’s nothing more frustrating than trying a project that may be too advanced for the skills of your child. And that’s when a lot of parents resort to doing the project instead. Not a good solution. So make sure your child is capable of completing the steps them self.
• Make a list of three ideas Have your child select three science fair project ideas and then go over the choices with them. Make sure they understand the steps involved in each project and wether or not they feel comfortable in executing those steps on their own with your guidance.
• Follow your child’s interests Encourage your children to explore some ideas based on interests they already have. Here’s a list of science books with projects based on things your child already loves!
• STEAM it up! STEAM projects rock the science fair!!! A great way to get kids to become more familiar with STEAM concepts it to pick science projects that crossover into art, math, engineering and more!  Two STEAM books to consider are  STEAM Kids Play and Learn (my book!) and   STEAM Kids ebook.  Both books will get you started with some great ideas!
• Read our Science Fair Mini Guide I created this mini guide to walk kids  through all the steps for completing their science fair project. You can check out the full guide here: 

Speak like a scientist! Science Vocabulary to use in your presentation

We’re almost ready to get to the projects! Before we begin, let’s review some science terms. In fact, using these terms in your science fair presentation will be sure to impress your friends and adults!

• When you watch, see, or notice something you are making an observation
• When you ask who, what, when, where, why, or how, you are forming a question  
• When you read a book or an article about your observation, you are doing research
• When you make a guess based on your observation, question, and research, you are forming a hypothesis
• When you test your hypothesis, you are conducting an experiment
• When you change one factor in your experiment at a time while keeping everything else the same, you are changing a variable
• When you take notes in your journal and write down what you see happening in your experiment, you are logging data  
• When you examine, or look at, your data, you are analyzing it
• When you are able answer your question, you are coming to a conclusion

30+ Science Fair Projects for Kids 

Now let’s get on with the science fair projects! I have organized the projects by age/grade level. Click the titles to be taken to the project instructions, unless the instructions follow below.

There are a ton of different choices you can make in terms of testing your hypothesis, so feel free to be creative with it!

Topics: Psychology

Materials Needed: Smartphones

8. Memory Enhancement Techniques

Compare the effectiveness of various memory enhancement techniques. You can start by researching popular techniques such as mnemonics, spaced repetition, and mind mapping so that you develop an understanding of how these techniques work. Then you can begin experimenting by gathering a group of subjects and creating a memory test. Remember to control other variables that could impact your data and carefully think through your experimental design to ensure it follows the scientific method.

Materials Needed: None

9. Build a Model Roller Coaster

If you’re a big fan of amusement parks this could be a great idea for you. Design and construct a model roller coaster using different materials like cardboard, foam tubes, and marbles. You can experiment with factors like height and angles to see what creates the most velocity for the coaster. Be sure to document how specific changes in factors affect the outcome of the roller coaster ride!

Topics: Physics

Materials Needed: Cardboard, foam tubes, marbles

10. Build a Model Suspension Bridge

Start out by sketching your bridge design on paper and looking up images of real suspension bridges for inspiration. From there you can begin to use your popsicle sticks and glue to construct the bridge.

This is also a great idea to apply statistical analysis of your data.

Materials Needed: Plants, soil, water

14. The Impact of Light Pollution on Nocturnal Insect Populations

In this project you can first explore the concept of light pollution and what its effects are. From there you can research nocturnal insects and learn about their behaviors. The second part of the project involves conducting an experiment to see how nocturnal insect populations vary based on artificial light intensity. You can go to several different locations that have different artificial light intensities to see whether certain locations have a greater abundance of insects or a greater diversity. Keep in mind the tricky part of this experiment is how to collect the insects - there are various methods such as light traps or sticky traps that you can try.

Topics: Biology, zoology

15. Build a Solar Oven

Construct a solar oven using reflective materials such as aluminum foil. You can explore this article that explains step by step how to build the oven, but the basic idea is that you want to line the inner flap with aluminum foil so that the sun's rays reflect off of it and also create a small opening so that sunlight can come through. You can try heating up food in the middle of the day when the sun is directly overhead to see what happens!

Topics: Chemistry, Food Science

Materials Needed: Reflective material like aluminum foil, insulation (foam board, newspapers), heat-absorbing container, thermometer, food items for cooking.

16. How Temperature Affects Battery Performance

You can also vary the length of time that the batteries are left in a given temperature. After, use a voltage meter to measure the output of the batteries. How does temperature impact the voltage output?

Topics: Electrochemistry, energy storage

Materials Needed: Multiple types of batteries, thermometer or temperature sensor, voltage meter or multimeter.

17. Testing the Strength of Different Types of Paper

Compare the strength of various types of paper (printer paper, construction paper, tissue paper). To do this you can either measure the force required to tear each type of paper ( tensile strength ) or just observe how difficult it is to tear. Record observations and also analyze the different materials used in each type of paper to hypothesize why the paper might be difficult or easy to tear.

Materials Needed: Different types of paper, ruler or measuring tape, weights or force gauge, clamps or clips.

18. Pendulums

In this easy science fair project, construct your own basic pendulum with string and a weight, and see how the length of a pendulum affects its period (the time it takes to complete one full swing). You can also conduct trials where pendulums of varying lengths are released from the same angle, or vary the angle from which the pendulum is released.

Materials Needed: Pendulum apparatus (can be as simple as a string and weight), stopwatch or timer, protractor for measuring angles.

19. DIY Catapults

In this project you’ll explore the principles of projectile motion and trajectory. Build a simple catapult or trebuchet and investigate how launch angle and projectile mass affect the trajectory of a launched object. If you want to take the project a step further and add a history component to it, explore a few various catapults that were used in ancient or medieval times and observe the differences in their launch angles and typical projectile masses. Were these catapults effective?

Materials Needed: Catapult or trebuchet construction materials (wood, rubber bands, etc.), objects that the catapult can launch, measuring tape or ruler.

20. Friction

Explore the concept of friction by pulling objects across different surfaces and measuring the frictional force. You can investigate how different surface textures impact how easy it is to pull the object across the surface. To take the science fair experiment to the next level you can share your findings about one real world application where the concept of friction is very important (think things like sports or transportation).

Materials Needed: Objects of different weights, various surfaces (e.g., wood, metal, sandpaper), force sensor or spring scale, ruler

21. Studying the Effects of Music on Stress Reduction

We all have our playlists or songs that help us relax, but how can we actually confirm that music actually plays a role in reducing stress? In this project you can conduct experiments where participants listen to different types of music (e.g., classical, jazz, nature sounds) and their physiological stress responses (e.g., heart rate, cortisol levels) are measured before and after listening to the music. Before conducting the experiment see if you can do some preliminary research on the topic and what other experiments have been done.

Materials Needed: A device to play, physiological monitoring equipment, stress assessment scales.

22. Ocean Acidification and Coral Bleaching

Study how ocean acidification, driven by increased carbon dioxide levels in the atmosphere, impacts coral reef ecosystems. You can also look into coral bleaching and learn how it’s also related to ocean acidification. This science activity can be a bit more focused on research rather than actual experimentation, but if you’d like to develop a model to demonstrate ocean acidification and see how carbon dioxide affects water we encourage you to do that as well.

Topic: Chemistry, marine biology

Materials Needed: Cups, water, acid base indicator, baking soda, vinegar

23. Studying the Effects of Deforestation on Local Climate Patterns

Learn how deforestation affects regional climate conditions such as temperature, precipitation, and humidity. Specifically, you can analyze satellite imagery to assess changes in land cover in deforested areas over time. To get you started, check out this article on how scientists have been tracking deforestation in the Amazon for decades .

Topic: Climate, environmental science

Materials Needed: Satellite imagery or aerial photographs

24. Investigating Sinkholes

Sinkholes may seem like a chaotic once in a lifetime phenomenon but there are actually geological processes involved in the formation of sinkholes. Explore these processes and their potential hazards to human settlements. To learn further you can research specific areas that are known to have a lot of sinkholes and try to understand why this occurs from a geological perspective.

Topic: Geology

25. How Color Affects Mood and Emotion Description

Explore whether different colors influence people's mood and emotional state. You can design experiments where participants are exposed to different colors through images or objects and their mood responses are measured with self-reported scales or surveys. Analyze data and see if you can find any patterns. The more subjects you have in your experiment the better!

Topic: Psychology

Materials Needed: Images or objects that show mainly one color

How to Showcase Your Science Fair Project

Winning Science Fair Projects [Get Inspired By Past Winners!]

Have you won a science fair project?  Interested in sharing your idea?

What we’ve seen in 100s of winning science fair projects.

First, some projects are more advanced.  Some projects were winners in national science fairs.  However, that doesn’t mean a scaled-down version can’t be tried.  Or, maybe an alternative approach.

Second, many of these science fair projects were completed through a mentorship program.  What’s that??  Many universities offer mentor programs geared towards younger students.  These programs pair students with a research lab and faculty member.  Students do experiments with faculty members.  Check out our STEMium camp listings to see more examples.  Typically, programs recruit high school students.  However, if your student is in earlier grades, keep this in mind and explore opportunities in your area.

Third, a ton of solutions center on climate/environment science.  Very cool!!

Finally, ALL of the projects solve a problem or answer a question.  Read through the list and think about your “every day” problems.  Could you solve one with your own science fair project?

We don’t provide full experimental details –  that’s up to you!  Leave a comment below if you’re stuck on how to get started.  Still not sure where to start??  Feel free to check out our germiest spot in school experiment,   alka-seltzer bottle rockets , or our slime science fair project , which can be done in 1-3 days.  Let’s science!

Still not sure what to do??  Look at The Simpson’s science fair projects!

After literally decades on the air, The Simpson’s even covered the science fair!  Plenty of projects to inspire you such as…

Duffless (Season 4, Episode 16)

In our first example, Lisa grows a gigantic tomato with anabolic steroids.  Unfortunately, Bart intervenes, tomato gets destroyed and Lisa must come up with another project.  Her solution:  is my brother dumber than a hamster?

The Genesis Tub (Season 8, Episode 1)

Another Bart/Lisa science fair rivalry, but this time with a Halloween twist.  Her initial project idea is pretty good!  Can soda dissolve a tooth?  However, things go off the rails from there.

E-I-E-I-Annoying Grunt (Season 11, Episode 5)

Final example:  Less of a “traditional” project, but as the Simpsons are hiding out on a farm, Homer decides to try planting crops.  When Marge suggests fertilizer, Homer borrows plutonium from the power plant.  The result – a new hybrid tomato is born!

CONCLUSION:  It’s not whether you win or lose…  it’s how you do your science!

I’ll never forget my younger daughter’s second science fair experience.  She and her partner did a great job brainstorming ideas.  Then, the enthusiasm waned a bit.  Then, it came back!  After ~3 weekends the final project came together.  Overall, the parents really stood back and let them run with things.

While I helped construct a demo volcano, the board was entirely done by them (3rd grader style complete with Christmas lights!).  You might imagine that it might not have been as sharp in quality as others that had more parental assistance.  🙂

You know what?  It didn’t matter…

At the presentation, they knew their stuff!

They clearly communicated their hypothesis, their experimental design, results and conclusions.

Then…

THEY BLEW UP A VOLCANO!!  WOOHOO!!

When they came back to find a 1st place ribbon, the smiles were ear to ear!  Tons of shrieks and giggles!  Winning science fair projects don’t always start that way.  In the end, what’s most important — have a positive experience.

If you’ve won a science fair competition, share your project in the comments and what your winning strategy involved!  Or, if you’re struggling to narrow it down, share some ideas.

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

Source: @eriverselementary

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!

Science is fun ! Less fun: Everything about Science Fair season . Those two fold project boards give wicked paper cuts. Teachers seem to want a stressful amount of work put into each project. And there’s never anything cool about the last minute ideas you use when grasping at straws on the Sunday night before it’s due. Life just got easier, though. We’ve rounded up the best science experiments for each level of school so that maybe, just maybe, this year’s fair won’t cause too many tears (from you or from the kids).

Note: We’ve listed experiments in each section from easiest to the most advanced, time consuming or expensive.

Elementary School Science Fair Projects

1. Catapult time — What kind of objects fly further?

Think weight over shape.

2. How Can the Shape of a Boat Affect How Much Weight It Hauls?

Have kids create simple boats using cardboard and foil. Take note of how the shape and size of boats effects what they can hold and still stay afloat.

3. Water Drop Microscope

Microscopes are cool and science-y on their own, but laying out how water works to magnify things adds another level of, well, science.

4. Chromatography Butterfly Fun

Grab judges’ attentions with this gorgeous experiment in separating colors.

5. Can Changing Rubber-band Size Change the Speed/Distance of Travel on a LEGO Car?

This is a fun way to put your kiddo’s LEGO collection to good use!

6. Which Simple Machines Do We Use Most?

After explaining what each simple machine is and does, have your kids “collect data” on the types they use throughout their day. Consider having them walk through some of the more surprising simple machines in life.

7. Why Do Skittles Dissolve in Water? ‘

We know all sugar dissolves in water. But, does your child?

8. Kaleidoscope Fun

How many times did you play with your kaleidoscope as a kid and did you ever look into the physics involved? Your kids might enjoy making their own in the name of a school science project.

9. DIY Speakers

Ever need to boost the sound from your phone? You probably know the mug trick, then. Explore how different vessel shapes amplify sound.

10. Spinning Top Splatter Fun

Some paint, some tops and a little bit of research is all you need for a colorful lesson on centrifugal force.

11. Make Your Own Hovercraft

Say good-bye to one of your beloved mix CDs and help your kiddo experiment with aerodynamics .

12. How does different types of milk effect Magic Milk results?

Magic milk is so fun. Why not turn it into a science coloring experiment or science fair project?

13. DIY Bouncy Balls

Catch ’em, if you can!

14. Overnight Crystals

If you’ve got Epsom salt, this cool science experiment won’t even require a trip to the store.

15. Tiny Dancer, Simple Motor

You might need to buy some copper wire for this, but it’s totally worth it for the cute factor alone.

16. Heat Sensitive Slime

Take your slime game up a notch and win the science fair all in one night.

17. How does over/under watering affect seeds?

This is pretty easy. Just use that old school plastic cup and paper towel seed growing trick, but have your child experiment with how much water they use.

18. Rubber Rainbow Eggs

This takes a couple days and could end up being messy , but it’s another eye-pleasing experiment.

19. How Do Plants Absorb Their Water?

Remember sticking celery or daisies in colored water? Same concept.

20. Which Kind of Trees Lose Their Leaves Fastest?

This one is all about collection and observation, so make plenty of time to start this.

Middle School Science Fair Projects

21. Density Tower

This tower of liquids is like the next-level oil and vinegar experiment.

22. Which Reacts Faster: Small Chunks or Large Tabs of Alka-Seltzer?

Did you know that the dissolution of an Alka-Seltzer tab can be qualified as both an explosion and a chemical reaction? Let your kids explore different theories on how to make it dissolve the fastest.

23. How Do Submarines Work?

Help build a water bottle submarine , then explore how they dive and resurface by changing their buoyancy.

24. Does Weight Affect A Drone’s Battery Life?

Remember that drone you bought your kid for their last birthday that they no longer play with? Of course you do. Put it to good use!

26. Create A Simple Circuit

The hardest part of this project will be finding D batteries in your house.

27. What Makes The Perfect Chocolate Chip Cookie?

Need a bunch of holiday cookies made? Let your kids experiment with butter temperature, baking soda and baking powder ratios and other variables within a cookie recipe. Nearly all results will be delicious, but it still counts as a science experiment.

28. DIY Stethoscope

This requires a trip to the hardware store. But, it’s a great way to discuss how sound travels and how stethoscopes work .

29. Can You DIY Yogurt?

Know anyone who makes their own yogurt or Kombucha? This is a great way to discover the science behind bacteria growth (and maybe get your kids to start washing their hands).

30. Can A Cricket Tell The Weather?

Spend a few days or weeks having kids compare the chirps of crickets to the temperature fluctuations outside.

31. Building Materials: Which Metals Are Most Corrosive?

Chances are good that you have plenty of different types of metals readily available (think: screws, silverware, change, foil, etc.), all you need is the time to test things out.

High School Science Fair Projects

32. Do Adults Still Know What They Learned In High School?

Have your kids collect questions from various exams and then administer the new tests to adult friends and family members from a wide range of fields.

33. Can I Change The Colors Of A Bonfire Flame?

Tossing different (non-toxic) litter into a bonfire (or even holding it over a candle) can cause the flames to change color.

34. What’s The Most Effective Natural Mosquito Repellent?

Don’t volunteer as a test subject.

35. How Does Social Media Usage Vary Between Generations?

This basically just requires a lot of research using their own (and possibly your) social media accounts to see what and when each age group is posting.

36.How Can You Speed Up Homemade Ice Cream?

Between rock salt and actual ice cream ingredients, this is a bit of a financial investment. The good news is that you can drown your concerns in ice cream.

37. Is My Mom’s Gold Jewelry Real?

Some chemicals found in gold and silver can have toxic properties that are harmful to bacteria. Can your pretty necklace kill ? Find out.

38. How Can You Keep A Parked Car Cool?

Test temperatures in various colored cars, as well as the effectiveness of sun shades and parking under trees.

39. Does Tire Air Pressure Really Change Gas Mileage?

Basically, an excellent science project and life lesson in car maintenance for your teenager all in one.

40. How Safe Is Your Microwave?

Track plant growth over several weeks — keep one place near the microwave and one further away.

41. Which Type of Bread Molds Fastest?

Pro-Tip: Have them store their science project bread somewhere far, far away from where you keep your actual bread.

42. Could Hospitals Recycle Their Bio-hazard Collection Resources?

Blood vials, urine collection cups, barf buckets: They’re all used as single-use plastics. But, could they be properly sterilized and reused? You’re probably going to need to know people in the right places to make this work, but it’d be a very cool experiment.

How to Do a Science Fair Project

Need help getting started on your science fair project? In this video series, a JPL scientist, engineer and educator team up to help you learn how to come up with an idea for a great science fair project and see it through to completion.

Project Steps

Step 1: introduction.

To get started on your science fair project, you'll learn to observe the world around you and ask questions about the things you observe.

Step 2: Get your idea and do some research

Observe the world around you and ask questions about the things you observe.

Step 3: Ask a testable question

Develop your idea into a question you can test. Your question should follow the format, "How does [input] affect [output]?"

Step 4: Design and conduct your experiment

Design your experiment and keep track of the results. Remember to only change one variable and conduct your experiment multiple times for each trial. Each trial should be repeated in exactly the same way.

Step 5: Examine your results

Now that your experiment is done, it's time to examine your results. You want to look for trends in your results and draw conclusions from those trends. You also want to examine your data for possible influences from factors you didn't consider at first.

Step 6: Communicate your experiment and results

Make a poster display that summarizes your experiment so you can share your results. Be sure to include the question you were trying to answer (your hypothesis), the steps you took to answer that question, your results and any factors that may have influenced your results. Your poster should be visually appealing, but also clear about what you did and why people should care.
