I’m amazed at how quickly we could get to free body diagrams when I assume the kids remembered something of their physical science class last year. We’re already talking about the motion-related implication of balanced forces.

Today was the first day of 2nd semester for 2/3 of the classes I teach. Above is from one of them. I asked the kids to also list out all the types of forces they knew about, to tell me what they remembered of Newton’s Laws of Motion, and to roll a bowling ball across the tile foyer of our science building (all to prove we have few Jedi among us who can move the ball after it leaves their hands).
