Wednesday profitable

The morning session was really interesting. I learned a lot more about polarized lenses. Really liked the petri dish and vegetable oil illustration. It would be pretty cool to have polarized filters in my microscopes; difficult? price? Our chemistry class will definitely be doing the copper wire and silver nitrate exercise. It's very inexpensive and really illustrates single displacement nicely.
The afternoon was interesting. I think,with some practice, the high school kids could pair up with younger ones to make pretty cool thermometers. I can visualize these things placed strategically around the elementary school with daily readings being taken.
