Sound!

We are just beginning to discuss sound. Yesterday we discussed common sounds in our environment. They listened to a tape of sounds from around the house and had the children had to guess what they thought they were. Everyone laughed at the sound of a toilet flushing and knew immediately what it was. Other sounds were a bit trickier. Only a few recognized a blender and a blow dryer. Today we introduced a new word..." Vibrate". We tried to make observations about how sound is made. We gently pressed our hands on our throats as we sang a song. Many felt our vocal cords moving or vibrating! They were moving back and forth quickly. Here is a song we learned today:

When things vibrate,
They wiggle back and forth,
They wiggle back and forth,
They wiggle back and forth,
When things vibrate,
They wiggle back and forth,
That's how sounds are made.

We watched an elastic vibrate!
