Sound Energy Experiment

This term in Room 2 we have been looking at energy.  Today we investigated sound energy.

Here is our description of what we did.

We had some spoons.  We had two each.  We tied string onto one spoon and then we put the ends of the string in our ears.  Then we hit the spoon with another spoon.

We sent energy into the spoon and it made a sound when it went up into your ears.  It traveled up the string and it echoes back in your ears.

Here's what we had to say after this experiment...

Connor
When you put the wool in your ears and someone hits the spoon that's tied to the wool with the other spoon, it sounds different.

Declan
When I put the wool in my ears I hear different noises.

Korah
The different sounds are different.

Sarah
It sounds like an old clock.

Tobias
It sounds like a haunted clock.

Zacqlin
It sounds very haunted and very scary, but once you put it up by your ear it sounds way higher, and if you put it down lower it sounds different.  But if you put it by the tippity-top it sounds very, very scary.

Thomas
If you put it higher by your ears it'll be like an old clock but it sounds like it was like a haunted one.

Reed
We hear it because we are putting energy into it.

Ashton
I heard a different noise when I put the spoon lower.

Zana
When you put it near your ear it sounds like in a deeper noise.

Marlin
It sounds cool because it is different.

Amber
It sounds different.

Reef
When you hit it, it sounds like a light noise but when you don't hit it it doesn't sound like anything, and when you put it in your ear and hit it it makes a deep noise.

Jack
When you hit the spoon very hard it makes a louder sound.

Niah
When you put it in your ears it sounds different and it sounds like an old clock.

Calla
It sounds like a monster clock.

Ava
If you tapped it with a stick it would probably be very loud.

Brooklyn
It sounds a bit different when you hit it with the spoon and if you hit it with a pencil it will sound quiet.

Charlize
When Sarah hit it with the spoon lightly it sounded louder than when she hit it hard.

Zara
When you hit it with the spoon it sounds cool.

Rhyot
When you hit it with the spoon it vibrates in my ears.

Aroha
When the people banged it I thought the noise goes through the yarn to your ear.
