Sound of silence

This week  we started our study of sound. The students learned that there are 4 things you need to hear a sound: a vibration which is a back and forth movement of energy , a medium for the vibration to move through, an ear to capture the sound wave ,and a brain to identify the sound that is being made.

Skyla is loving this experiment!

We had two days of experiments so far and there wasn't a voice to be heard. These children were so focused on hearing the sounds being made and categorizing the pitch of the sounds.  Pitch is the highness of lowness of a sound . The students learned that the slower the vibration the lower the pitch. Also the longer the vibrating column the lower the pitch. Conversely the oppsosite is true. Faster, shorter, higher. This information will be useful when the students engineer their own instruments. Details coming soon. Enjoy the view from Room 205
