- we began class by talking about what conservation of charge means
- no electrons are created or destroyed when we are talking about electricity, they just move from one spot to another
- we then reviewed a bit of previous concepts while going into some new things
- identified a shock as static discharge
- we then talked a little bit about lightning and how it is actually a form of static electricity
- explained to the students why we use lightning rods
- students were confused why we would build things to make lightning strike them
- explained that the rod is there as protection so the lightning can find its way to the ground
- lastly, we talked about why it is not safe to be in a wide open place during a lightning storm
- a car is actually a very safe place to be during a lightning storm
