Flow of Charge and Practice Exam

We started the day with one question on bellwork: Why can bird stand on a high-voltage power line without getting shocked?

This lead to a discussion of electricity, which is actually our next unit. When you don't have a potential difference, no charges flow and therefore there is no electricity. Watch this video of some kids touching an electric fence; until the last dude, all of those kids were at the same potential, insulated from a different potential (ground), so there was no electricity flowing through them.

After that we started working on the electrostatics practice exam.  Unfortunately some of the content is copyrighted, so although I CAN give it to my students I CANNOT post it on the internet. Email me at miss.volkening@gmail.com for a copy. 

Next week is sequential, so Monday will be a work day and Tuesday will be your test.
