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 science fair guide (.pdf) for tips on how to brainstorm topics, design experiments, and present your results.
