Strange Sounds

During Science Week Ms. Burke came in and did an experiment with us. 

We explored Sound!

We found out that sound is energy.

We did an experiment to see sound.

We needed:

A drum (we used boxes and tins!)

Clingfilm

A bowl

Rubber band

Rice.

How we did it:

1. First we stretched the cling film over the bowl and secured it with a rubber band.

2.  We sprinkled some rice on top of the cling film.

3.  Next we banged our drum beside the bowl with the rice on top.

   

 

 

Results:

We could see the sound. It moved the rice and made it dance. The closer the drum was the more the rice danced.

We also  felt sound. You can feel it too! Just put your fingers on the outside of your throat when you are talking. Can you feel it?

Next we tried another way to feel sound.

We used: a balloon.

How we did it:

We held the balloon against our ear and our partner pressed their lips against the balloon and spoke.

Results:

We could feel the vibrations through the balloon when they spoke.

Next:We decided to see how many balloons we could hear through.

 Rian could hear through 7 balloons.
