Day 154: Curved Mirror Equation & Percent Composition

Physics: Curved Mirror Equation

Students collected a little more data from yesterday’s lab, then whiteboarded the results to get to the curved mirror equation. The graphs were not as consistent as with some labs, but students were still able to get where I wanted them to.

Chemistry: Percent Composition

Last trimester, a lot of my students struggled what they knew about percents from their math classes to percent composition in chemistry. This tri, before giving any instruction, I asked students to  answer a few questions like “What percent of this class is male?” Giving students those questions, then asking them to talk about the process they used, got students to bring the math into the class themselves, which lead students to make sense of percent composition much more easily than last trimester.
