There can be no sound without?
Vibrations
What transmits energy from one place to another, resulting in sound?
Waves
Match the following
How high or low a sound is Amplitude
How loud or soft a sound is percieved. Frequency
the number of vibrations in a given amount of time Pitch
The height of a sound wave Volume
How high or low a sound is pitch
How loud or soft a sound is percieved. volume
the number of vibrations in a given amount of time frequency
The height of a sound wave amplitude
What does sound need to travel?
Draw how particles move in (solid, liquid, gas)
which does sound move the quickest and why?
Solid because the particles do not move as fast or as long as liquid and gas
Match the Medium to the correct Speed>
Solid 1, 077 ft/second
Air 4, 539 ft/second
Water 16, 960 ft/second
Air 1,077
Water 4,539
Solid 16,960

Student conduct an experiment to see which drum will have the lowest pitch, on a snare drum and a bass drum, what are the variables for the experiment?(Hypothesis, Independent Variable, Dependent Variable, Constants)
Hypothesis: If you hit a mallet on a snare drum than it will maker a higher pitch than when you hit a bass drum.
IV: the drum size
DC: the pitch
Constant: The mallet and the type of surface on the drums
