What are subatomic particles?
Atoms are too small to be seen, but scientists have learned much about their structure. Atoms are made of even smaller particles called subatomic particles. Make a slide-show presentation that describes the structure of an atom. Your presentation should include information about the size, mass, charge, and location of each type of subatomic particle. Show your presentation in class or post it to your class blog.
