AP Physics: Free Response
We are starting to review proper for the AP Physics 1 exam. Today, I gave students the 2015 free response and asked each group to sign up for a problem they will become the experts on. There was lots of good discussion about reading carefully and parsing what the question is really asking.
Physics: Standing Waves
We got out the wave generator and a strobe light to get a few more ideas in place about standing waves. The strobe light helped a lot with talking about the particle motion since it became possible to track the movement of the string.
Chemistry Essentials: Whiteboarding
We spent some time whiteboarding yesterday’s problems. We spent a lot of time on the first problem, which had nice whole number mole ratios, so we could look at how the particle diagrams show what math needs to be done.
