Things to think about:
1. What exactly *is* charge? How do we think of it? How does this relate to protons and electrons, etc.?
2. Why is it that electrons are the easiest particles to manipulate?
3. What does atomic number (Hydrogen = 1, Helium = 2, etc.) mean? Also - What does charging an atom entail - How can an atom be charged negatively or positively?
4. What are quarks?
5. Coulomb's law is an "inverse square law" - what does this mean exactly?
6. Why can a charged balloon stick to a wall?
7. What is "grounding"?
8. Recall the demonstration where I charged up the small suspended piece - what was I showing? Or the demo with the pie plates.
9. Is the charge of an electron a big or small number? Roughly, how many electrons would be needed to make 1 coulomb of charge?
