AP Physics: Problems
Students worked on some oscillating particle problems. Students had some really good discussion about a cart on an angled ramp oscillating on a spring; a lot of groups really dug into what should happen when the angle of the ramp changes. At the end of the hour, we tested their predictions. I wasn’t paying much attention to when I started data collection, but still got a set of graphs my 2nd hour considered applause-worthy.
Earth Science: Glaciers
I gave students a brief overview of some glacial features, then had them use some sand in the stream tables to make a recreational area with a variety of glacial features. Students liked the activity, but they did not connect the vocabulary to how the features form or how they are related. I think I’d prefer to do this at the end of a glacier unit, where students would have the background to tie the features they are using together. At this point in the unit, I’d rather focus on how these features form to give some basis for naming them.
