Readers Respond: High School Science Fair Project Ideas

Responses: 38


High school science fair projects are expected to invent, solve a problem, model or otherwise innovate. It can be really hard to come up with a good science fair project idea. Sometimes it helps to see what others have done or to read project ideas. Have you done a high school science fair project or do you have a good idea for a high school project? Here's your chance to share what you think with other readers. What's your project idea?

Tooth Decay

These were some pretty great science projects. I think a neat one would be "which chemical makes teeth decay faster?" of course you have to work with real teeth but hey who doesn't want to keep their teeth nice and healthy?

Microbiology and Electrophoresis

My project deals with growing a gene called pGLO on E. coli through bacterial transformation. We do this to see if the pGLO takes amino acids away from the other proteins. Then we use protein gel electrophoresis to see the results. I know it's a really advanced science fair project. But I'm in 10th grade. It's not that hard if you have you're teacher help you with it. The more challenging a science fair project, the better! Good luck!
