Day 117: Kirchhoff’s Laws, Problems, & Balancing

AP Physics 1: Kirchhoff’s Laws

Students used PhET’s circuit construction kit to look for patterns in series and parallel circuits. Students were pretty successful at noticing the things I wanted them to notice and I’m looking forward to tomorrow’s discussion of the results.

Physics: Problems

Students worked on some problems using the spring period equation. We also spent some time on whole-class discussion about the motion graphs for an object on a spring, and tested a lot of ideas using a motion encoder cart hooked to a force sensor with a spring.

Chemistry Essentials: BalancingĀ Reactions

Students used PhET’s balancing chemical equations simulation to start figuring out what it means for a reaction to be balanced. Students were pretty successful at working out the significance of each of the tools the PhET activity provided, along with what it means to be balanced. Even though I didn’t assign the game, a few students decided to play and ended the hour with a lot of confidence and enthusiasm for balancing problems.
