Science Buddies: "Ask an Expert"

Hi there, I'm looking for an Investigatory Project that is interesting and not yet discovered or proven. I have made an Investigatory Project last-last year and I'm able to finish it but my professor told me that, that project was just for Elementary or Grade School Students. So now we're about to make a new project that is Environmental, Physical and Biological (any of the three) I need your help. Do you have any suggestions?

By-the-way, we need to finalize our topic next week(Monday).

Hello? Help me please??

Have you looked through Science Buddies' topic selection wizard, here? It has lots of great projects, including some that are appropriate for high school: http://sciencebuddies.com/science-fair- ... l?From=Tab
