We finished standing waves today, for the most part. I had students gone to a concert, and I knew some of the pictures would be difficult to draw, so we did a lot of working in groups today. We also explained the results to our sound lab, and our results came out pretty darn close to what we expected.
When I went around the room today, trying to get a sense of where we were as a class, some students really liked this unit. Students told me that they liked how it applied to music, liked how it seemed to make sense, and liked that they could be successful with it. A few students didn't like the unit, but that came from the fact that it didn't feel like the rest of physics. Well, physics contains lots of different models. You're just going to like the beauty of some models more than others.
