Okay, here's a few:
1. What are the forces produced by electrical and magnetic fields?
2. Why does force cause some objects to change shape?
3. How do hot air ballons become inflated?
4. Why do bicycle tires become flat?
5. Why is it more dificult to ride a bicycle with flat tires than with inflated tires?
That oughtta keep 'em going!

Define "gravity" and how it relates to centrifigul force.
