We experimented with tuning forks today, and our class had a lot of great insights. Because I’m not allowed to post student first names on our site, I have identified students by the first letter of their first names.
It sounds like it’s humming… It sounds like it’s someone screaming, like “oooooh†(X)- It sounds like a fan, when you’re close to it. (A)
- It sounds like a well when you call into it. (R)
I can feel it vibrating (R)- It’s like when you’re at the hospital and you can see the graph on the screen going up and down (E)
- It sounds like a bell when you hit it on your shoe (L)
The big one makes a different sound from the little on (K)- The small one sounds louder and the big one sounds deeper (E)
- When you look at it it looks blurry (L)
The big one is different because it’s taller (P)- It sounds like a vibrating coin going down a well (R)
- It sounds like when you hit the bell at a hotel (X)
Here’s a video of handbells, which are kind of like tuning forks with megaphones to make them louder. :)
You can see a tuning fork in super-slow motion here:
And here’s “Ode to Joy” in tuning forks.
