What topic should I write about in physics paper?

[andjelatodorovic]

I want to write a paper that includes some inovative experiment results. It's a high school project so many things in physics are unknown for me. What topic whould you recomend(based on what hasn't been fully discovered and yet doesn't include complex knowledge of mathematics)?

Archimedes principle would b a great start, or the physics of rainbows requires only basic mathematics and some knowledge of optics.
