Day 82: Springs, Linearization, & Whiteboarding

AP Physics: Springs

Students started collecting data for variables that affect the period of a spring. I found it interesting that students were quick to suggest stretching the spring farther to change the period after seeing angle doesn’t matter for a pendulum; I suspect they just aren’t making the connection yet. A lot of groups used motion detectors to measure the period, and one student found the graphs so satisfying she snapped a photo of the LabQuest to show off.

Physics: Linearization

Students were pretty quick to treat yesterday’s data on the compression of a spring launcher vs. a cart’s change in height as linear, probably because we haven’t linearized any graphs in a while. We spent some time today talking about what intercept would make sense and why before a quick review of linearization. Afterwards, groups worked on making linearized graphs of their data.

Chemistry Essentials: Whiteboarding

Students did some whiteboarding the problems from yesterday. I had all groups whiteboard the same problem, when we shifted to whole group discussion. The physical space in my room lends itself pretty well to having whole group discussions with students at the lab tables, but a lot of students were having trouble with the transition to whole group discussion. Next time, I think I will have students physically move to give a clearer cue that we are changing the kind of activity.
