Day 129: Wave Superposition & Stoich

Physics: Wave Superposition

We spent some time discussing the observations students had made about wave superposition yesterday. There was some good debate about whether pulses were reflecting off each other or passing through each other. Students then practiced sketching superpositions based on the original waves.

Chemistry: Stoich

We spent some time discussing the lab students did yesterday and really focused on how they knew when and what to multiply or divide. We also spent some time explicitly discussing what the hardware represented and how what they were doing was similar to a chemical reaction. Afterwards, I gave students some more traditional problems using actual chemical reactions.
