Reaching K-12: Biology-Related Science Fair Project Ideas

Doing a science fair project can be very daunting, especially for a child who’s never done one before. To help out the burgeoning biologist (or parent of a biologist-to-be), here we’ll explore some great biology-based science fair project ideas provided by Science Buddies. And since deadlines for many fairs are quickly approaching, we’ll focus on project ideas that don’t take more than a few days to complete.

Science Buddies is a non-profit involved in K-12 science and engineering education with an amazing library of 1000+ freely available science project ideas (though I might be biased since I’m a scientist/writer at Science Buddies). While here we’ll highlight project ideas that are suitable for the middle school audience, science project ideas ranging the entire K-12 spectrum are available through Science Buddies. (We previously highlighted the many stem cell-related science fair project ideas that are available through Science Buddies.)

The following science fair project ideas are great for middle school students who want to do a biology-based project and have a looming deadline for the fair. (I’ve actually tested and/or written several of these project ideas.) They’re arranged by interest area.

Human Biology & Health

Human Behavior

Mammalian Biology & Zoology

Plant Biology


Genetics & Genomics

Medical Biotechnology

Chemistry & Biochemistry
