AP Physics 1: Levers
Students did a lab with levers to introduce torque. I usually take 3-4 days on lever labs, so tried to shorten it. In my 2nd hour, I had students graph the ratio of the forces on one axis and the ratio of the radii on the other; the results so far are looking messy, so I think I tried to accomplish too much with that approach. In my other section, I had half the class keep the positions constant and graph the two forces, while the other half of the class keep the forces constant and graphed the distances from the pivot. The results are looking really nice, so I think that was a better abbreviation.
We whiteboarded and discussed a couple of wave problems from TIPERs. Students seemed to find the problems pretty straightforward.
Chemistry Essentials: Gallery Walk
We did a gallery walk to go over Friday’s problems that combined balancing with molar mass. Students are starting to be able to shift away from the blocks we’ve been using for balancing and rely more on their particle diagrams, which is great to see.
