Ive fallen flat on science fair ideas. All the ideas Ive come up with have been shut down by my teacher saying "Oh, we already know that." I attempted 7 different ideas, but with no avail.
So Im all out of ideas. Im open to almost anything (besides plants), but would like to do something that related to heat and fire. Any kind of physics project would be great too. Just anything you guys have got, cuz Ive got nothing.
Please help,
Thanks in advance
