I haven’t doted enough on 6th period. This class is ah-ma-zing — always inquisitive and up for any inquiry I throw their way.
So today I introduced the biggest part of our unit on sound — the musical instruments project. Students will work in pairs to build a wind or stringed instrument so they can play a song. Today I pulled out the sound tubes and select YouTube videos to get the kids thinking. With the sound tubes, kids found notes 2-3 octaves apart and the pictured student was able to play something resembling “Taps”.
What was today’s warmup in 6th period?
An interesting little rounding issue bit us in the butt today: if you write the wavelength of the third harmonic as 0.333… but then use 0.3 to find frequency, the frequency is off by a whole lot. Knowing that f3 should be 3f1, I knew something was off but it took me awhile to spot the error as rounding.
