Sense of Sound

Kindergarten scientists explored the sense of sound with several investigations. After striking tuning forks, we watched and felt the vibrations. The tuning forks were not all the same size, and therefore created different pitches (high and low). I placed a vibrating tuning fork on a drum head and in water. When we placed the tuning forks on the table, the sound was louder. Sound travels differently through solids.

 

We looked at the inside of an ear and learned the smallest bones in our body can be found there.

Then, we listened to our voices travel through whisper phones.

Finally, we watched the strings vibrate on my real guitar before we plucked the rubber bands of varying widths on our DIY string instruments.
