Describe the function of the tiny hairs inside the cochlea.

The tiny hairs in the cochlea wiggle in response to soundwaves and send signals to the brain.

Explain how the middle ear helps with hearing.

The middle ear amplifies soundwaves and moves the stronger signal to the inner ear.

I can describe how the ear helps us hear sounds.

1
The auricle, or the flappy part of the ear, helps to collect soundwaves and directs them into the auditory canal.
2
The middle ear amplifies soundwaves and moves the signal to the inner ear using three tiny bones.
3
The cochlea, which is shaped like a snail shell, contains liquid and tiny hairs that send signals to the brain.
