Fifth Grade: The Science of Sound

March 1999



1 Sound travels fastest through which of the following?
gas
liquid
solid

2 A sound wave's amplitude determines:
How high the pitch is
How loud the sound is

3 A sound wave's frequency determines:
How high the pitch is.
How loud the sound is.

4 In a high frequency wave, the wave period will be:
close together
far apart.

5 In a low frequency sound wave, the wave period will be:
Close together.
Far apart

6 When you walk into an empty house, the echo you hear is because of the
Doppler effect
Acoustical effect

7 If a sound is high-pitched and soft, the sound wave is:
high frequency and high amplitude
high freuqency and low amplitude
low frequency and high amplitude
low frequency and low amplitude

8 If a sound is high pitched and loud, the sound wave is:
high frequency and high amplitude.
high freuqnecy and low amplitude.
low frequency and high amplitude
low frequency and low amplitude

9 If a sound is low pitched and quiet, the sound wave is:
high frequency and high amplitude
high frequency and low amplitude
low frequency and high amplitude
low frequency and low amplitude

10 If a sound is low pitched and loud, the sound wave is:
high frequency and high amplitude
high frequency and low amplitude
low frequency and high amplitude
low frequency and low amplitude

11 When a car or train passes you by and you hear the pitch of the engine appear to change as it passes, you are hearing an example of:
the Doppler effect
an Acoustical Effect

12 When your mother tells you to turn down the radio she is asking you to:
Lower the frequency of the sound wave
Raise the frequency of the sound wave
Raise the amplitude of the sound wave
Lower the amplitude of the sound wave

13 When you stretch a rubber-band tight, it makes a high pitched sound. Is the sound wave generated by this tight rubber band a higher frequency or a lower frequency sound than it was?
Lower frequency
Higher frequency

14 When an architect designs a house, he/she must consider the shape of the rooms and the materials the walls, floor, and ceiling are made of in order to prevent the house from being too loud. To do this, he/she must know about:
sound waves
acoustics
building materials
noise pollution
all of the above

15 A baby's voice produces sound waves with a higher or lower frequency than a man's?
lower frequency
higher frequency

16 The bass drum in the band produces a sound wave of a high or low frequency as compared to a snare drum?
High
Low

17 Tuning a musical instrument like a guitar changes the:
Amplitude of the sound waves
Frequency of the sound waves
