AP Physics 1: Ohm’s Law

Students used PhET’s circuit construction kit to find a relationship between current, voltage, and resistance. It was the first time students were asked to work with three variables at once on a pretty open-ended lab, but they were very successful at coming up with ways to approach the task.

Physics: Spring Period

Students finished their data collection and graphing for the period of a spring lab. A lot of groups went straight to a quadratic relationship to linearize their graph, which makes me think they were treating it as an automatic process, rather than thinking through what their graph suggests. It didn’t take much coaching to get students to switch to a square root linearization, but I’ll need to keep working on what it actually means to linearize a graph.

Chemistry Essentials: Mistakes Whiteboarding

We did some mistakes whiteboarding using yesterday’s problems on representing reactions. Students were very successful at figuring out the mistakes and they are gradually getting the hang of the various details they need to carefully represent.
