CCSD SCI 4 Unit 7 Interim - Sound

A bell makes a sound when it is hit by the clapper. When the clapper hits the bell slowly, a low pitch is heard. When the clapper hits the bell quickly, a high pitch is heard.

Which statement BEST explains why the bell can provide a low pitch sound and a high pitch sound?

• A. The vibrations in the bell are faster when the clapper hits the bell slowly.

• B. The vibrations in the bell are slower when the clapper hits the bell quickly.

• C. The vibrations occur at the same speed.

• D. The vibrations occur at different speeds.

Anna is shaking a sheet of metal to make the sound of thunder for her school play. What will happen if she shakes the sheet of metal more quickly?

• A. The vibrations will be faster and produce a quieter sound.

• B. The vibrations will be faster and produce a higher sound.

• C. The vibrations will be slower and produce a lower sound.

• D. The vibrations will be slower and produce a louder sound.

A student noticed that the sound of a fork tapping on an empty glass changed when water was added to the glass. Why did the sound change?

• The thickness of the glass interferes with the vibration of the fork.

• Sound quality varies with the type of liquid used.

• Sound travels faster in water than through the air.

• The amount of water in the glass affects how fast the glass vibrates.

Members of a band have different musical instruments, as seen below. In which way are all of the musical instruments alike?

• They all use a vibration to make sound waves.

• They all send sound waves in only one direction.

• They all make sound waves with the same amplitude.

• They all make sound waves when two objects strike one another.

During a science investigation, students explore the production of sound by varying the strength and speed of vibrations in everyday objects. As part of the investigation, they observe that a tightened guitar string produces a higher-pitched sound compared to a loosely tightened string. What conclusion can be drawn from this observation?

• The weight of the guitar affects the pitch of the sound.

• The color of the guitar influences the pitch of the sound.

• The speed and strength of vibrations impact the pitch of the sound.

• The temperature of the surrounding air determines the pitch of the sound.

When you drop a spoon on the floor, it makes a loud sound. When you drop a spoon on a soft chair, it does not make a sound. What is the difference between the floor and the chair that accounts for the sound?

• The floor vibrates more than the chair.

• The floor is more reactive than the chair.

• The floor is more insulated than the chair.

• The floor has more potential energy than the chair.

How is sound produced in a musical instrument like a guitar?

• by vibrating parts of the instrument

• by shining a light on the instrument

• by pressing buttons on the instrument

• by changing the color of the instrument

How sound is made?

• From vibration that disturbs the surround molecules

• Ultrasonic transmission from transmitter

• The ossicles detection pass into the inner ear

• The ability to perceive sounds by detecting vibrations
