KONOS Attentiveness - Sound Experiments

Here's the pics from our sound experiments from July....

Here the kids are finding out how sound travels by using a bowl that is wrapped with cellophane and then salt is added to the top.  As the yell it vibrates the cellophane.

Here they're using rubber bands over the top of an open container to make an instrument and to tell which one will vibrate and make the higher or lower tone... and yes we shop at Trader Joe's ;)
