CONDUCT RESEARCH
Use your resources! It's very likely that someone else, somewhere in the world, is wondering the exact same things you are!
Scour the Internet, your local or school library, course textbooks, a media center in a school, and credible online databases to see what information people already know about your topic.
Maybe your question is already answered - this is a good time and place to move forward with the scientific method and use your research to design your own experiment or try out someone else's.
