AP Physics: Angular Acceleration

This year, I’m embedding circular motion concepts as we wrap up their linear motion analogues, so today students took their first look at angular acceleration. Students used a Direct Measurement Video to plot angle vs. time for a disk with a rocket motor attached. Students were quick to notice their graph looked a lot like position vs. time for an object with linear acceleration, and were able to extrapolate a lot from there.

Earth Science: Satellite Data

Students looked at some images of cloud cover produced by NASA’s GOES satellite to make some claims about the cloud cover and associated weather in a few areas of North America. I didn’t use my evidence-based reasoning graphic organizer today, and I don’t think its a coincidence that many students just stated their claims without any evidence. I need to keep being explicit about what good reasoning looks like and stay on students to keep including that in answers.
