**AP Physics: Toilet Paper**

Students started a lab practical I got from Frank Noschese’s blog. Students were given a height they will drop one toilet paper roll from and are tasked with figuring out where to drop an unrolling toilet paper roll so it hits the ground at the same time. I’m trying to emphasize the ways that students are using forces and constant acceleration in the practical to make sure this is doubling as a review for the final exam.

**Earth Science: Galaxy Sorting**

Students were given pictures of a dozen galaxies and tasked with putting them into categories and naming each category. Most groups came up with something pretty close to the three official categories. I can’t decide if I’m happy about that. On the upside, my students are very comfortable with the vocabulary. On the downside, the fact that so many groups got similar results tells me there was limited thinking required.
