Product Description

Video and lesson investigations on the topic of the ear. Key concepts include:

  • The ear is divided into three parts: the outer ear; the middle ear; and the inner ear.
  • The outer part of the ear funnels sound down the ear canal (a tube about three centimeters long) towards the middle ear where the eardrum is locate.
  • The eardrum vibrates when sound vibrations hit it.
  • The vibrations are then transmitted through three tiny bones in the middle ear known (because of their shapes) as the hammer, the anvil and the stirrup.
  • The stirrup bone pushes directly against the inner ear with is filled with fluid.
  • In the inner ear, the vibrations move through the fluid and cause tine hair-like cells to move.
  • These, in turn, are connected to other nerve cells which send messages to the brain.
