Concept: Sound moves in waves.

When a drop of water falls into a container of water, how will the waves move?

Please draw what you see.

If a rock is dropped into the container of water, how do the waves move?

What happens when the waves hit the sides of the container?

If this were sound what would that be called?

Does the water move across the container?
(Watch the cork; does the cork move across the container?)

Explain what you see.

If sound works like the waves of water, does a vibration send a molecule of air to your ear, or does it bump into other molecules on its way to your ear?
