Sound is energy made by vibrations.

Sound waves keep going until they run out of energy.

Sound waves require a medium through which to travel.

Sound cannot travel through a vacuum or space.

Sound travels through solid 13 times faster than air.

Sound travels through a liquid 4 times faster than air.

Sound travels through mediums at different rates.

Sound travels faster through a solid and slower through air.

More volume = more amplitude

Amplitude = volume or intensity of a sound

Frequency (speed of wave)  = pitch

More frequency = higher pitch

Less frequency = lower pitch

Draw a wave and label all the parts. (crest, trough, resting point, wavelength, amplitude)
