Sound is usually heard. Sound can be felt, but it can also be visible. To help young learners see sound waves we used Apple Voice Memos to quickly capture sound and see the waves created. We used markup to annotate a screenshot to label where students thought it was the loudest, quietest and compare and contrast the sound waves they saw/ heard. Students then had a chance to record their own voices using the alphabet, counting or a sentence of their choice in various voice volumes. Teachers were able to check for understanding by having the students annotate their own screenshot or discussion.

What a great activity and a wonderful way to use voice memos! I'll be sharing this with my pre-service music educators. 👍🏼
I'm not sure what grade levels these students are, but this activity could also be expanded to measure duration (time or millimeters) of sounds and for students to try to guess which instruments made each audio waveform [snare drum 🥁 (short, no decay), guitar 🎸 or piano 🎹 (even decay), or trumpet 🎺 (likely a sustained block of sound)]. Also, students could determine if the beat is steady or unsteady by measuring the distance between transients/blips. You've ignited my creative mind with this. Thanks, TechZ! 😎🎵🎺
