I am forgetting to take pictures! Aargh! We started by playing with tuning forks, seeing them splash in the water, and how the tines feel very weird when you touch it to your nose. I showed them how to get from s = d/t to the wave equation. We played with beats, which I taught without giving them any reason to believe it. And we modeled the Doppler Effect with this Desmos graph. I also learned how to make a Desmos gif today, so that was cool.
Today was also a day where my class felt comfortable. We're coming together as a group, and for me, that often happens when we move being silly to being serious quickly.
