Science Buddies: "Ask an Expert"

Any ideas for a project starting with a mrble in motion?

I was looking through the other posters, and i see a thread that another student is doing the exact same thing, and one of the experts told the student, that, by what the rules said, we arents alowed to give directions...She said to search over at google, there might be some great site that might be helpful. Sorry I couldnt be more help
