This part of the ear collects sound waves.
What is the outer ear?

Of these, it is the one that is not a scientifc observation: Some tuning forks produce higher pitched sounds Water will vibrate when a vibrating tuning fork is placed in it. Some tuning forks produce sound that is not too pleasant. If you strike a tuning fork hard, it produces a louder sound.
What is some tuning forms produce sounds that are not too pleasant?
300
It is the first part of the ear to vibrate from sound waves.
What is the eardrum?
300
This can be used to show an example of a sound wave compression
What is a slinky spring?
300
Bats and dolphins use this to navigate and find food.
What is echolocation?
300
We can describe the pitch of sound being this if it's source is vibrating quickly.
What is high-pitched?

Erika has ten slices of bread from the same loaf. She places five of them in a dark closet. She places five on a windowsill. Mold grows on all ten pieces. We can make this conclusion from this data.
What is mold can grow without light?

This is the correct path that sound travels through our ear.
What is the outer ear, eardrum, and inner ear?
400
This property of sound describes the loudness of a sound wave.
What is amplitude?

This causes sounds.
What are vibrations?
