Websites

i am in a advanced science class and i need to come up with a science fair idea
i looked around the web, but i could not find any good websites. i am in 9th grade so it is like a 10th grade science class, i really need a good project that is easy to do, i dont want to buy a lot of things and it needs to prove something, tell me the procedures adn the materials needed

thank you
i would like to do it on something with dry ice or fir, but any easy project is ok
