I'm a college junior and I have a class for physics majors where we need to come up with an experiment to do over this semester (and he's giving us only 1 day to come up with possible ideas). I really don't know where to begin. He says we can look up experiments and sorta replicate them and use the internet for ideas if we can't think of one already. Are there any good sites where maybe I could get ideas from or any basic ideas I can work off of? It can be anything that involves some sort of measurement that can be done by December (I'm not sure what our budget is). Any ideas/websites/etc would be greatly appreciated.
