Hmm... you should do a unique and interesting one that nobody else in the competition would think of. Best of luck to you. x
You could do the discovery of Type 3c diabetes, commonly misdiagnosed as type 2. :thonk: Or the discovery of radioactivity? Idk Science is fun.
Maybe you could do something that Stephen Hawking discovered? He was one of the greatest minds in science last time I checked.
