6.
Describe the direction heat energy always moves.
a)
Heat always moves from a cooler area to a warmer area
b)
Heat always moves from a warmer area to a hotter area until they boil over.
c)
Heat always moves from a cooler area to another cool area
d)
Heat always moves from a warmer area to a cooler area, and this action continues until both areas are the same temperature.

8.
A guitarist strums two strings of the same thickness on a guitar. The first string vibrates more quickly than the second string. What is true about the pitch of the strings?
a)
The first string has a higher pitch than the second string.
b)
The second string has a higher pitch than the third string.
c)
The first string and the second string have the same pitch.
d)
The pitch of the second string depends on the energy of the first string.

Convection
c)
Radiation
d)
Reflection
10.
How would a drum played in outer space sound different from a drum played on Earth? Explain
a)
A drum playing in space sounds louder than a drum played on earth because the amplitude increases and the sound gets louder as you travel through space.
b)
A drum played on Earth would have a higher frequency, or pitch than a drum played in outer space because humans weigh more on Earth than in space.
c)
A drum played on Earth would create sound because vibrations can pass through air. However, since outer space is empty, playing a drum would create no sound.
d)
A drum played in outer space would create sound because there is no gravity in outer space, while a drum played on Earth creates sound because vibrations can pass through air.
11.
What happens when the amplitude of something increases?
a)
It sounds lower in pitch
b)
It sounds louder
c)
It has a higher pitch
d)
It has a higher frequency
12.
Which best describes a sound wave when the pitch of a sound is very high?
a)
It has a low frequency.
b)
It has a high frequency.
c)
It has no wavelength.
d)
It has no frequency.
13.
