AP Physics 1: Center of Mass
Students worked on a video analysis of two air pucks attached by a rod from the article by Taylor Kaar, Linda Pollack, Michael Lerner, and Robert Engles in The Physics Teacher. In the past, I’ve used LoggerPro, but there have been delays on getting it installed on student computers, so I took advantage of the video upload feature in Pivot Interactives. Pivot has a ruler with an adjustable length to get measurements to scale, but it was tricky to find a nice alignment, so students ended up skipping scaling the ruler and coming up with a conversion factor, instead.
Students whiteboarded some problems on drawing free body diagrams. In my 1st hour, we did mistakes whiteboarding; I was a little disappointed that no groups put a forward force on the objects moving forward, but not a lot of students made that mistake while they were working on the problems in the first place. My 6th hour is a little behind, so they mostly worked on the problems today and will do some abbreviated whiteboarding tomorrow.
Chemistry Essentials: Energy Bar Charts
Students worked on some LOL diagrams for energy transformations during phase changes. They had some trouble with the system flow part of the diagram, mostly because they are getting tripped up by the idea that it needs to list specific objects.
