Day 137: Doppler Effect & Limiting Reactants

Physics: Doppler Effect

I tried something new to introduce the Doppler effect today. Students slid transparencies along a grid and sketched wavefronts to get a sense of how a moving source changes the frequency a stationary observer would hear.

Chemistry: Limiting Reactants

Students worked on some problems to identify limiting reactants. I shared a strategy one of my students came up with last tri to use reaction diagrams to help think through the problems, which seemed to help students wrap their heads around what the different numbers represent.
