Day 96: Compound Circuits & Empirical Formulas

Physics: Compound Circuits

Students continued to work on yesterday’s compound circuit problems. A few students yesterday traced different paths through the circuits using colored arrows to provide a visual cue for which currents should add up, and a lot of students today found it helpful to add that representation. I was really pleased when a student insisted that the last problem, with the most complicated circuit, was the easiest in the set.

Chemistry: Empirical Formulas

Students finished up the lab from yesterday, then worked on some written problems finding empirical formulas. I didn’t take the time to discuss the connections between what the lab represented and what they were doing in the problems, and many students struggled to not only transfer ideas from the lab, but to bring back skills like converting mass to moles. I need to make sure I take the time to help students build those connections.
