The outer ear acts like a funnel and directs
sounds waves into the ear canal.
Sound waves bump against your ear drum and
make it vibrate.
These vibrations get three little bones shaking.
The bones are called the hammer, anvil and
stirrup.
These bones
cause fluid
inside your
ear to move.
The fluid is
inside a part
of your ear called
the cochlea
(coke-lee-uh).
Inside the
cochlea are
tiny nerve endings
that send the
sound information to
your brain.
Follow the sound of the jingle bell to
find out how our ears work!
Standards Link: Life Science: Humans have structures that serve different functions.
Church bells, jingle bells,
Laughter,
Wrapping paper crinkles,
Holiday sounds from toots to tinkles.
How marvelous it is to hear,
All because of our two ears!
