Day 160: Graphite Wire, Pendulum Review, & Energy Bar Charts

Today was the start of seniors’ last week of school.

AP Physics: Graphite Wire

Students continued to work on their final projects. One student used a graphite pencil to sketch “wires” on a sheet of paper and worked on collecting data on the potential difference at the LED. I wasn’t sure if a pencil would leave a thick enough layer of graphite, so got pretty excited when she got this to work.

Its hard to see, but the LED is glowing!

Physics: Pendulum Review

With the final exam starting on Thursday, we took some time today to start reviewing. I started with some pendulum questions that I expected to be pretty quick and easy, but it took a lot longer than I hoped. I didn’t do as nice a job of spiraling as I would have liked this spring, so students were very rusty on some of the concepts they needed.

Chemistry Essentials: Energy Bar Charts

Students worked on energy bar charts for chemical reactions. The hardest part for a lot of students was parsing what exactly was happening at each snapshot for the energy bar carts; in general, I haven’t pushed the idea that some representations are like a photo that shows a specific instant while others are like a movie that shows change over an extended period, which would have helped today.
