Exploring the Connection Between Length & Sound

11/2/2014

0 Comments

 
First graders investigated a range of materials to see the effect that the length of an object has on the sound it makes.  By stretching rubber bands on pegboards and over recycled materials, we discovered that the longer the object, the lower the sound.  This was most pronounced when we used boomwhackers.  When students struck each one, it was easy to hear the effect that length has on sound.
