AP Physics: Physics Puzzle
My classes were pretty thin today since the senior social studies classes were watching the inauguration. I gave students who were here the opportunity to do some in-class retakes. I also picked out a couple of fun puzzles from Mad About Physics that students could work on. Students got pretty into the puzzles, especially one where they can get a marble to roll “upwards” by adjusting the space between some straws in a v.
