Sound Unit Review

A student is investigating how to produce a sound. The student taps a metal pot with a metal rod. Which of the following will MOST LIKELY happen?

• The rod vibrates and makes a sound.

• The rod does not vibrate or make a sound.

• The rod vibrates but does not make a sound.

• The rod does not vibrate but does make a sound.

Jamie and Donna were looking at two sound waves. Donna said that sound wave A would make a louder sound. Jamie disagrees with Donna and thinks that sound wave B would make a louder sound. Who is correct?

• Jamie is correct because the amplitude of sound wave A is lower than the amplitude of sound wave B.

• Donna is correct because sound wave A has a wider wavelength than sound wave B.

• Jamie is correct because sound wave B has more crests and troughs than sound wave A.

• Donna is correct because sound wave B is a longer wave than sound wave A.

A student uses a cardboard tube to make an instrument. When he blows on the tube, it makes a sound. He then uses a shorter tube to make a second instrument. What will happen when he blows on the second instrument?

• The two instruments will make different sounds, but there is no way of knowing what type of sound they will make until you blow on both instruments and make observations.

• Instrument 2 will have the lowest pitch sound because the air column is shorter than Instrument 1.

• The instruments will produce the same sound since the vibrations are traveling through the same type of gas.

• Instrument 1 will have the lowest pitch sound because the air column is longer than Instrument 2.

Fourth grade students all created different ways to investigate sound. Which of the following will both groups encounter when producing sound?

• Both groups will hear a sound, but only group 1 will observe vibrations.

• Only group 1 will hear sound because the straw will vibrate and create a sound.

• Both groups will move an object that will create a response with a sound and vibrating objects.

• Only group 2 will hear sound because rubber bands are used to create vibrations when pulled on.

Luke wants to blow on the straw in his harmonica that makes the sound with the lowest pitch. Which straw on the harmonica will produce the lowest pitched sound?

• Straw 1

• Straw 2

• Straw 3

• Straw 4

• Straw 5

If you change the amplitude of a sound wave, what will happen to the sound?

• The sound will get higher or lower.

• The sound will travel faster to your ear.

• The sound will get louder or softer.

• The sound will stop vibrating.

Two students wanted to investigate sound and vibrations with the same materials. One student plucked the rubber band every 10 seconds. The other student plucked the rubber band every 20 seconds. What will the students observe?

• Speed does not affect vibrations so the students will hear the same sound.

• Both students will hear the same sound, but the vibrations will speed up when the rubber band is plucked more.

• The students heard the highest pitched sound when the rubber band was vibrating the fastest.

• The students heard the highest pitched sound when the rubber band was vibrating the slowest.
