AP Physics: Collisions

Today, we started expanding the momentum transfer model to cases where two objects are moving before the collision. We got out the photogates so students could find the velocity before and after various collisions of two carts. I got a kick out of how exciting it was for some students to use .

Physical Science: Presentations

Students presented their research projects on different energy sources. I like the sort-of-public forum to share their work, but it is tough for students to sit through a bunch of presentations, even though I never spend more than half the class period on them. For next year, I want to put some thought into other formats that might balance the public accountability with more active engagement. Maybe a poster session with some kind of task for students as they view each others’ work.
