[General Science] My science project

Alright, I really need some help here :confused: . I'm in ninth grade, and I'm doing my first science project, but I'm really in need of some help here. I'm having trouble coming up with a good field and project. I think I'd like to do something in either General Physics or Meteorology, but I'm not entirely sure of anything. Does anybody have any good ideas for a science project? Or, has anybody here done a good science project before? My teacher says we're allowed to do the same science project as anyone else, as long as we don't copy the entire project investigative report and presentation. So, I can use the same project topic/idea that one of you used, as long as I don't copy your report or presentation.

I'll keep this unlocked ONLY if the answers posted are ideas, NOT procedures, data, or materials. Part of the whole Science project idea is to develop your own experiment.

Ex: (you can use this if you wish)
"Effects of acid rain on the environment"
"How Lake Effect precipitation occurs."

Kapeesh?
