In this example the source is......
The _______ is vibrating to produce the sound.
To make a quieter sound, you would need to ........
Write a paragraph to describing and explaining how different sounds are produced. (6 marks)
Use the key words and copy the sentence starters below to write your answer.
Sound waves are…. I know this because…
When a sound is produced the source… The sound that we hear depends on these vibrations.
If the vibrations are very quick ……… and if the vibrations are slow the ……
If the vibrations are very large the sound will… and if the vibrations are small the sound will…
Challenge: Describe the volume and pitch of a scream. What kind of wave pattern would this sound have

Kinetic energy is stored in hot objectsA water wave is a transverse wave
A sound wave is a transverse wave
The frequency tells us the distance between two corresponding waves
Energy can be created but not destroyedThe oscillations in a transverse wave are perpendicular to the direction of energy transfer
Perpendicular means at a right angle to.
