AP Physics: Inertial Balance
Since about 60% of my students are taking the AP Physics 1 exam on the make-up date, I’m adding in some review activities along with working on the final project. Today, I set up the inertial balance and asked students to make a few predictions about the motion, as well as what should happen when the mass is supported vertically. At the end of the hour, we used a motion detector to check students’ predictions.
For the final project, students’ proposal was due at the start of the school day today, and a few students told me they were hesitant about moving forward before seeing my feedback. Next time around, a Friday afternoon deadline may be better since then I can get feedback before their next class period.
The other physics teacher and I decided to wrap up the year with some basic optics. Today, students made shadows and sketched ray diagrams to explain what they saw. A lot of students commented that the ray diagrams were a really useful tool to think about what was going on, which was nice to hear, since we’ve had to really work on buy-in on a lot of other diagrams this year.
Chemistry Essentials: Activity Series
Students did a simple lab to develop an activity series for several pure metals. Most of the solutions were 0.1 M, which wasn’t strong enough to get a very visible reaction in the time we had. Next time, I need to make sure I allow time to mix stronger solutions.
