Cup Phones
How does sound travel? We learned sound travels via vibrations. Vibrations in the air are called sound waves. Today we experimented with sound by creating cup phones and talking to our neighbors! Here is a snapshot of our conversation after our experience.
We made cups and we talked in them and another person put their cup to their ear. Cariah
We made some echos in the cup. Hold it tight! Greyson
It works because of the vibrations on the strong. Lucas
Why do we need the cups? Could we just use the string? Mrs. Goldsmith
The cups are actually for you to put your eat and mouth on so you can make the echo sound come in. And when youre like on the other side its kinda similar. We don’t know how it does it. Its like magic. Dylan
Was it more important to be the listener or the talker today? Mrs. Argus
Listener, because you have to actually like, be quiet to hear… Dylan
Yeah, like you listen! Beatrice
If somebody’s talking, you don’t talk through it. Dylan
Listening is more important because you can learn more about the person that is talking. J’Den
An amazing conversation. 🙂
