AP Physics 1: Problems

Students worked on some conservation of momentum problems, including Michael Lerner‘s watermelon on wheels, that require them to be flexible about the system they are using. A lot of groups went straight for a whiteboard once the work time started, which lead to some great discussion and collaboration on the problems.

Physics: Board Meeting

We had a board meeting for yesterday’s force of gravity lab. This was actually the first traditional formula students got from a lab this year. During the discussion, I could tell my students are getting much better at making “for every” statements about the slope and describing the meaning of the intercept.

Chemistry Essentials: Assessment

Students took their quiz on phase changes. One problem talked about a generic chemical, rather than something specific, which threw several students off. It was a good reminder to keep problems firmly rooted in real situations. Afterward, we revisited the mystery tubes from the first day of class as preparation to start talking about the periodic table and atomic models.
