Class Update

Wednesday, March 24th. Today we puzzled through the details of the reading on voltage and current. The reading was pretty dense, we focused in on voltage, current and resistance. We defined each looked at how they affect circuits and then looked at Ohm's law (V = I x R) and how to calculate one part if you know the other two parts. For homework I gave everyone an excerpt from "The Way Things Work" by David MacCauley. It uses the analogy of water to explain an electrical circuit. Monday we discussed the film "Kilowatt Ours" by Jeff Barrie, that the class watched last week when I was in Philadelphia for the National Science Teachers Association conference. Tuesday we worked on our electric vehicles. They are looking for materials to use in building their cars and will get to work on them again on Friday.
