I need help beating all my friends in Science Fair

[deleted-532467]

I really want to do better than all my friends. I love them, but I MUST WIN. (for real though)
Okay, so basically I have to do a topic that I can 100% do an experiment on, and all the ideas I have are "trash" and I am starting to freak out because deadlines are coming soon.
I want to do something similar to the "Creating a kidney: How stem cells might be used to bioengineer a vital organ"; however, I cant do that because 1) I read the procedure and had no idea what was happening, 2) it looked very difficult. 3) it wasn't an actual experiment. Other than that, bioengineering sounds dope. Then I looked at Amoeba organisms and thought, wow, that looks great! So if anyone can help me with that, I'd be eternally in your debt. Solar-powered, space, wind energy, water energy, anything that a 9th grader could do I would be down.

Thanks, I really appreciate you looking at this, whoever you are!
