AP Physics: Central Force Whiteboarding
Students whiteboarded some problems dealing with a central net force. My students who have taken Astronomy are pretty excited with the connections they are seeing to orbits. I also pulled up a simulation of Newton’s Cannon to talk about a problem that asks why the ISS doesn’t crash into the earth.
Physics: Projectile Motion Mistakes
We did the mistakes game, focusing on the diagrams and initial set-up for problems rather than all of the math. There are a lot of long silences, so I might try giving students some structure for additional pre-discussion with their lab groups next time. Maybe students could do a gallery walk and jot down some potential questions for each whiteboard. There are a lot of groups opting to use “vertical” energy to solve for key values, which is pretty cool.
Chemistry Essentials: Balancing Mistakes Game
We did the mistakes game with yesterday’s problems on balancing chemical equations. I’ve got the opposite problem of my physics class, where lots of students have things to say, which leads to too many people talking at once. Most of my contributions end up being to re-focus the discussion or redirect students, rather content-related questions to move things along. I’m okay with this problem, even if I’m not sure how to solve it yet.
