Cymatics are the study of wave phenomena, especially sound waves, and their visual representation. A friend’s son saw the video below in class and I’m so glad she shared the link. What an amazing way to discuss wave functions. It is visual and auditory and really, quite stunning overall.
I would love to utilize this video in a class some day – if nothing else to show students that science is indeed all around us – even in our music.

That is a pretty neat cymatics video. There’s another science lesson that involves using a speaker and dripping water and, well, I’ll share a link that explains everything very well. I for sure want to perform this in my future physics classroom.
