Sound

Shari is using a tuning fork to learn about sound properties. She is tapping the tuning fork, placing it in the bowl of water (see image), and observing the waves created by the vibrations. Which is an observation Shari most likely made?

• The harder the tuning fork is hit, the larger the waves in the water.

• When the waves begin to slow down, the tuning fork vibrates faster.

• The longer the tuning fork is in the water, the higher the waves get.

• When the tuning fork is taken out of the water, it is completely dry.

As Maria and Carl stood in the kitchen talking, a car drove by the house. The music was blaring so loudly that Maria commented, "That loud music makes it seems like my heart is beating with the music! "Well, something is beating with the music," shouted Carl. "Look at the windows!" The windows in the kitchen were vibrating to the beat of the music from the car. What is the MOST accurate explanation of the vibration of the windows?

• Sound does not cause the vibration of matter.

• Sound waves echo through air.

• Sound waves will never push particles back and forth.

• Sound waves transmit energy as compression waves.

As the band passed by, the beating drums and trumpets made Billy feel like his body was beating with the music. He could hear the music and he could feel it!How would a scientist explain this to Billy?

• Sound waves are transmitted faster through gases than through solids.

• Sound waves cannot travel through the air

• The marching causes the ground to move which Billy feels

• Sound waves transmit energy through all forms of matter.

Keisha plays the drums in her class band. Every time she strikes the drums the audience hears the deep beat. The sound that the audience hears is created

• in the drumsticks as they vibrate every time she strikes the drums.

• when the surfaces of the drums vibrate after being struck by the sticks.

• by the vibration of the floor on which the drums are placed.

• due to the vibrations passed through the floor of the hall.

If you have ever plucked a guitar string, you know that it keeps making sound for a while after you pluck it. This is because the string keeps vibrating, and these vibrations keep producing sound.

• The vibration of the strings causes vibrations in the air, which reach your ears.

• The vibration of the strings causes sound particles to fly into your ears.

• The vibration of the strings causes your ears to vibrate, and this is known as hearing.

• The vibration of the strings is detected directly by your ears.

  The vibration of the strings is detected directly by your ears.
