Project Ideas

Remember, your science fair project should start with a question. What topic interests you most? What have you always wondered about that topic? Once you’ve decided the question you want to answer, everything from the hypothesis to the procedure will flow from there.

Animals and Insects

Earth, Sun and Stars

Food and Our Bodies

Oceans, Rivers, Streams

Plants and Gardening

Water Quality

Weather

They have a section devoted to science project ideas, and at different difficulty/detail levels… really cool.

Good luck, and have fun with it!
