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.
If you’d rather have the science fair projects list organized by subject you can download our hyperlinked PDF by subscribing to our email list here .

3. Shiny Pennies
A classic experiment that kids love is Shiny Pennies . Collect dirty tarnished pennies and have kids soak them for a minimum of 5 minutes in different acidic liquids. We used vinegar, salsa, lime juice, and lemon juice. After soaking, remove them from the solution and rinse in soapy water then compare which ones are shiniest. Take notes on which acid worked best to shine the pennies. Variation: Don’t rinse all the pennies after removing them from the different liquids. Can you see a difference in the rinsed vs. non-rinsed pennies? Leave them overnight and see if any of the copper oxidizes (turns green) on the non-rinsed pennies.

The best chemistry science fair project is one that answers a question or solves a problem. It can be challenging to come up with a project idea, but looking at a list of chemistry projects other people have done may stimulate a similar idea for you. Or, you can take an idea and think of a new approach to the problem or question.
Tips for Finding a Good Idea for Your Chemistry Project
- Write out your project idea in the form of a hypothesis as per the scientific method. If you can, come up with five to 10 hypothesis statements and work with the one that makes the most sense.
- Keep in mind how much time you have to complete the project, so don't select a science project that takes months to complete if you only have a few weeks. Remember, it takes time to analyze data and prepare your report. It's also possible that your experiment won't work out as planned, which would require you to develop an alternative project. A good rule of thumb is to choose an idea that takes less than half the total time you have.
- Don't discount an idea just because it doesn't seem to fit your educational level. Many projects can be made simpler or more complex to fit your level.
- Keep your budget and materials in mind. Great science doesn't have to cost a lot. Also, some materials might not be readily available where you live.
- Consider the season. For example, while a crystal-growing project might work well under dry winter conditions, it might be hard to get crystals to grow during a humid rainy season. And a project involving seed germination may work better in the spring and summer (when seeds are fresh and sunlight is favorable) than in late autumn or winter.
- Don't be afraid to ask for help. Parents, teachers, and other students can help you fine-tune a science fair project idea.
- Follow rules and regulations. If you aren't allowed to use live animals, don't choose an animal project. If you won't have access to electricity, don't pick a project that requires an outlet. A bit of planning can save you from disappointment.
Examples of Good Chemistry Project Ideas
The following is a list of interesting, inexpensive science fair project ideas. Consider the different scientific approaches you can take to answer each question.
- Can you use a black light to detect invisible spills or smelly stains in carpeting or elsewhere in the house? Can you predict what types of materials will glow under a black light?
- Will chilling an onion before cutting it keep you from crying ?
- Does catnip repel cockroaches better than DEET?

What is a Science Fair Project?
A science fair is a longstanding tradition that many elementary, middle, and high schools have where students conduct scientific research and share their presentations before judging.
A science fair project should include all of the following elements before entering a science fair:
- Background research
- Bibliography and source list
- A question to answer and a hypothesis to test
- Experiment variables
- Data recording and analysis of the experiment
- Conclusion report
- Visual presentation
If your science fair project includes all of these elements, you are well on your way toward a winning science fair project idea!
What Do Kids Learn Doing Science Fairs?
Kids who do science projects report greater confidence and understanding of all scientific concepts, both in what they explored and the scientific process in general.
Learning to analyze and explore data helps children approach other tasks in a logical, straightforward process which helps improve study skills and communication skills.
One of the greatest values that science fair projects bring is the ability to identify problems and work toward a solution. That is an invaluable skill that kids can use throughout life.
Of course, kids learn the basics of whatever scientific concept they are learning, plus the scientific method, which involved:
- Analyzing and Recording Data
But more than that, kids also learn other valuable skills like:
- Presenting an idea
- Creating a presentation
- Organizing data
- Analyzing data
- Patience and orderliness
- Working with others
- Precision and care
- Adapting to changes
- Communication skills
These skills are important far beyond the classroom!

The goal of a science project is not to prove your hypothesis right or wrong. The goal is to learn more about how the natural world works. Even in a science fair, judges can be impressed by a project that started with a bad hypothesis. What matters is that you understood your project, did a good experiment, and have ideas for how to make it better.
A hypothesis is a tentative, testable answer to a scientific question. Once a scientist has a scientific question she is interested in, the scientist reads up to find out what is already known on the topic. Then she uses that information to form a tentative answer to her scientific question. Sometimes people refer to the tentative answer as "an ...
