This week as we continued our study of sound, we learned more about how the human voice works. We looked at diagrams of the parts of the body involved and watched a video of vocal cords at work as four people sang.

As we discussed resonance, we gathered in different spaces, including the bathroom, the classroom and outside and noted how the sound differed in each space.

We also welcomed a close friend of mine, Caitlin Lynch, who is a professional opera singer, to our Science class to share with us the ways she cares for and uses her voice.

Lisa then discussed resonant frequency with us using wine glasses and showed how one can use that understanding to break glass with sound alone.
