Once Upon a Time Life is a series of videos from the 1970's created for kids to learn about the human body. By watching The Ear episode, the kids learned about the three bones in the ear which amplify vibration, the ear drum, and how the ear helps with balance.
Sound travels in waves, and the vibration of sound can be transformed into motion and be felt. To begin this lesson we discussed different types of waves.
Next the kids tried creating several loud noises to see the ear drum vibrate.
Our other Human Body projects can be found on our Science Page.
