AP Physics 1: Torque Board Meeting
We had our board meeting to get to the definition of torque. As expected, in the class where I had students plot the ratio of the forces on one axis and the ratio of the radii on the other, results were rough and I had to step in. In my other section, results came out beautifully and students were quick to figure out why their graphs had intercepts. I also introduced students to Brian Frank’s area models for torque, which students seemed to grasp.
We used slinkys to start figuring out some ideas about longitudinal waves. Students were pretty successful at noticing the things I wanted them to notice. As with transverse waves, we tied some ribbons on the spring to help track the particle motion.
Chemistry Essentials: Molar Mass Lab
I got out samples of several different materials, and had students weigh a sample and figure out how many moles they had. Not the most dramatic lab, but it was some good practice.
