Day 151: Space Yo-Yos & Volcano Types

AP Physics: Space Yo-Yos

Students continued work on their projects. I showed students Rhett Allain’s recent post on fidget spinner physics as a really strong example of what I’d like. Yesterday was also the last AP exam that a large percentage of seniors at my school take, and the combined result is a lot of students seemed much more focused on their projects today. In one hour, a student was talking through the physics behind some yo-yo tricks, and started trying to figure out which tricks should work in space and why. Turns out, there is video evidence for some of the tricks he said don’t require gravity!


Earth Science: Volcano Types

Today, I introduced students to the three main types of volcanoes. First, they predicted whether wet sand, ooblek, or a pile of scoria could make a taller volcano to get them thinking about the physical properties that lead to the shapes of the different types of volcanoes.
