I was home sick today and provided AP Physics 2 with a series of practice problems to work on individually and then confer with their group. I would have otherwise incorporated these problems into peer instruction. Most of the problems were from the Ohio State University PER group. It will be interesting to compare how they justify their answer to a question like the following based on what they’ve explored so far and how that changes after they complete the mapping electric potential lab and visualize electric potential surfaces.
