Any Suggestions for AP Chemistry Extra Credit Project?

[lovelylila]

I'm in AP Chemistry and I'd like to do an extra credit project for this marking period. My teacher welcomes all varieties of extra credit, from posters to videos to research papers to pictures of chemistry in the world, etc. Does anyone have any suggestions for a solid extra credit project that would definitely take effort and be at an AP-level?

Thank you in advance, I'm having so much trouble deciding what to do!

How about making different batteries, each using a different set of materials (electrolytes, cathodes, anodes); or design a simple exercise or demonstration for Thin Layer Chromatography for inks, or plant pigments? Maybe try a photometric titration?
