AP Physics: Final Project
Students continued to work on their final projects. In another class, two students built a pretty serious launcher for balsa wood planes and have decided to make their physics final project about explaining some of the things they’ve noticed with their launcher. The majority of students are making good use of their class time; I think it helps that I gave clearer expectations for what students should turn in partway at key points partway through the project.
I also had a free response problem for students to work on that we talked through at the end of class. I didn’t have a whole lot of students who opted to work through the problem themselves, I think partly because I used a secure practice test that students can’t take home.
Students did a qualitative lab experimenting with the images produced by lenses. I had electric candles to use as light sources, but students got really excited when I suggested they could try a picture on their phone. I loved the surprise when students covered up part of the lens and saw no change in the image.
Chemistry Essentials: Reaction Rates
Students worked on a lab to test how certain changes affect the rate of a reaction. The lab I used was pretty structured, but students had a lot of great ideas about how to effect the rate of a reaction during the pre-lab discussion. I think this lab would work very well as a modeling-style lab next time around.
