Day 54: Rotational Inertia & Big Bang

AP Physics: Rotational Inertia

We finally collected data and prepped whiteboards for the rotational inertia lab we’ve been working on. Tomorrow, we’ll spend part of the hour on a short whiteboard meeting to figure out what rotational inertia is proportional to. Students did a nice job of working through all the calculations they had to do to get from something they could measure to the rotational inertia, and it was a good review for the final exam later this week.

 

Earth Science: Big Bang

We discussed the lab from last Wednesday, where students made a graph to find Hubble’s Law. In the discussion, we focused on this result as evidence for the expansion of the universe. Afterwards, I ended up lecturing on the Big Bang Theory and some of the other evidence supporting it. I’m rushing a little bit as I try to cram material in at the end of the tri. Today was a reminder that over the summer, I want to spend some time with the curriculum, comparing it to the required state standards and the district-approved learning targets to get a better idea of what I can cut and where I can add build in more time for scientific practices.
