I met with three out of four of my classes today and shared with all of them how a closed pipe resonator works. BecauseI had the parents playing with resonance in a closed pipe setup last night, I just left the setup out and started with that.
The kids were, like, “Whoa!” when they first heard the resonance.
Then I was all like, “Shut the font door! What just happened there?”
They were dying to understand the phenomena.
So, I was all like, here’s how it works (see board above).
What was the 4th, 5th, and 6th period warmup?
I handed out this image on 1/4 sheets of paper. My old Interactive Notebooking self kinda enjoyed that. Note to my next-year self: lay down a grid behind the image and include more than one repetition of the interference pattern. Was a nice lead-in to talking about beats. After warm up, we looked at this video.
