Science Fair Project FAQ

How do I start a science fair project?

Science fair projects are a fun and unique way to discover science by asking a question and doing a science project. We'll help you find a science fair project idea and guide you through the process of doing and presenting your science fair project with Science Fair Coach's Science Fair Project Guide.

What are some hands-on ways to find inspiration for my science fair project?

Science museums are great places to explore if you're looking for inspiration for your next science fair project or just want to learn more about science. Science museums, natural history museums, space museums, and discovery museums are all great places to do that! You can discover all sorts of interesting things about science and find cool project ideas for science fairs.

There may be free admission days or free passes to a science museum near you! Check your local library for free museum passes, nearby science museums for free entrance days and your credit card for offers.

Find a science museum near you and prepare to be awed by all that you can learn there! I always learn something new and am inspired whenever I go to a science museum!

What should I do after I have a science fair project idea?

If you have a science fair project idea, Science Fair Coach can help you turn it into a full science fair project! Starting at Introduction to Science Fairs, we'll guide you through how to do a science fair project, from designing and conducting your experiment to collecting and analyzing your findings. Then, we'll help you showcase your results on a science fair board with our Guide to Science Fair Posters.

How do I make a science fair board?

Your science fair board is where you show off your science fair project for everyone to see and learn from. With our Guide to Science Fair Posters, you can make sure your science fair board stands out and impresses at the science fair!

What is the scientific method?

The 7 steps of the scientific method helps us understand how nature works. Learn how the scientific method is used in a science fair project example, and how it's evolved through history as scientists used different ways to learn about nature with our Guide to the Scientific Method!

What is the engineering design process?

The 6 steps of the engineering design process helps us design an effective solution to a problem. Learn how to use the engineering design process with the example of the egg drop challenge in our Guide to the Engineering Design Process!

Where can I find a science fair competition?

Science fair competitions are an excellent opportunity to explore science. One of the of the premier science advocacy organizations, the Society for Science, is associated with more than 400 science fair competitions in almost every US state, as well as over 70 other countries, regions, and territories. You can find out if there's a Society of Science affiliated science fair near you!
