I had a sub today.

AP Physics 1: Circuit Problems

I introduced students to Trevor Register’s KVL diagrams yesterday. Today, I had them work on some problems using the diagram and Kirchhoff’s Laws.

Physics: Lab Practical

Students started a lab practical where they using a spring to find an unknown mass two different ways. I gave them some structure that should steer them to use Hooke’s Law, then the period of the spring. I’ll be curious to see how it went.

Chemistry Essentials: Balancing

Students worked on some problems balancing chemical reactions. At my co-teacher’s suggestion, we got some Mathlink cubes for students to use as a manipulative. I’m curious to see how it goes; when I used some on Tuesday, they seemed to help make balancing more concrete for students.
