Vibration
Sounds happen when something vibrates
Sound has to travel through something
We don't always see the vibration
Sounds are transmitted (travel) through air or other materials
Sounds can travel through brick, glass and even WATER!
Sound cannot travel through a vacuum
We hear sounds when vibrating air hits our ear drums
The vibration is then picked up by our brain.
The more energy (the harder you hit something) in the vibration the louder the sound
Its measure in decibals
Pitch
This is how HIGH or how LOW a note is
The shorter the vibrating object the HIGHER the Note
The tighter the string on an instrument the highter the pitch of note
Think of a small dog with a squeaky bark
The longer the vibrating object the LOWER the note
If the string on an instrument is looser it will have a lower pitch of note
Think of a big bear with a deep growl
