text: can anyone suggest a physics-related science fair project? our school is holding a sort of like science fair, actually, a contest between the grade 9 and grade 10 levels. it's not that i want to win this thing but my teacher's kind of pressuring the whole class to win this so being critical as she really is, rejected my science fair project idea. so please, i need help! suggest anything that is physics-related that is also appealing to grades 7 and 8 who will be our target audience since no one expects our competitors to drop by our booth. umm... i'm in physics right now also, trying to think of a great summer assignment for the class.  i would suggest something like rockets (7th and 8th graders always love rockets), or a trebuchet (catapult).  those are always fun to make, and everybody loves those projects.  so, have fun!
