Information for Teachers
· There are three main parts of air. The outer ear consists of an oval portion and a long ear canal. There is an ear drum at the end of ear canal.
· The middle ear has 3 tiny bones. When ear drum vibrates, it produces vibrations in these bones. The internal ear transmits these information to the brain and we hear sound.
