Finding a topic that interests you is a key part of a successful science fair project! Here you’ll find dozens of ideas organized by topic or grade level. Once you find a few project ideas that interest you, develop your own specific question to answer. Use the scientific method to design an experiment that helps answer a question, such as ‘what effect does temperature have on seed germination?’

As you search for a project, also take a look at our free A Science Fair Guide to Get You Started (PDF) for tips on how to brainstorm topics, design experiments, and present your results. For popular science fair kits and supplies, see our shopping guide to get you started!
