The ear?

• The ear is a fabulous combination of passages and small bones which allows us to hear voices, music, the noise of the wind and the song if the birds: it is a simply marvellous organ.

The ear has three parts:

The outer ear –pinna

The middle ear – canal

The inner ear

What is you ear for:

Balance & Hearing

Hearing is an external sense, because the provide information

about the outside world.

• Balance is an internal sense because it provide information the

body needs.

How do we hear:

• Your ears pick up sounds and send hearing messages to the brain. Sound travel through the air in waves. The outer ear catches sound waves, then it travels through the ear canal and hit the eardrum this cause vibrations (like a real drum). These vibrations are send to the brain. And our brain tells us the message.

• This happens very quickly.

Fun activities1. Paper Cup Phones Give each child a pair of paper cups and a length of string. Have

them make a hole in the bottom of each cup with a sharp pencil. Thread the ends of the string through the holes in the cups from the outside in, making a knot at each end of the string to keep the string ends from slipping out of the holes. Have one child stand at one end of the room while the other child moves as far away as needed to make the string taut. Each child will take a turn speaking into the "phone" while the other listens at the other end. This only works if the string is taut.
