For you to hear sound, which events must take place first?
Your eardrum vibrates when the sound wave reaches it.
An object vibrates to make a sound.
Air particles vibrate as sound moves through the air
What is the best explanation for why sound travels faster in air at 45 °C than at 0 °C?
Warm air particles have less energy and vibrate more slowly.
Warm air particles have more energy and can vibrate faster.
Cold air particles have more energy and can vibrate faster.
Cold air particles have more energy and vibrate more slowly
Payton's cousin turned her speakers up so loud that it shook the walls and made a plant fall from a shelf to the floor. Her mom asked, “How can a loud sound make something fall?” What is the best explanation for Payton to give to her mom?
Loud music created a magnetic field that attracted the picture to the floor.
The electrical energy from the speakers transformed into thermal energy.
Vibrations from the music transferred mechanical energy through the walls.
The pitch of the music was too high to transmit energy
What could the student do if they want to add a higher pitch sound to the water xylophone?Select ALL correct answers.
Add water to glass #1
Remove water from glass #5
Add water to glass #5
Add glass #6 with 100 mL of water
Sound is the ___________ of energy between particles.
creation
destruction
transfer
frequency
Sound travels in compression waves. In the model, sound is traveling across a room from the speaker to someone’s ear. What is represented by the blue particles in this model?
sound particles
radiant energy
electrical energy
air particles
For you to hear sound, which events must take place second?
Your eardrum vibrates when the sound wave reaches it.
An object vibrates to make a sound.
Air particles vibrate as sound moves through the air
Why does sound travel slower through gases (air) than through liquids (water) or solids (gold and glass)?
Particles in gases are closer together than particles in liquids and solids.
Gas particles have less energy than particles in liquids and solids.
Particles in gases are further apart than particles in liquids and solids.
Gas particles transfer energy better than particles in liquids and solids
What is the best explanation for why rubber band E had the highest pitch?
It was vibrating the fastest.
It was vibrating the slowest.
It is purple.
It was closest to the student’s ear.
Which of the following are true statements about this model? Select ALL correct answers.
The model does not show the speed of the air particles.
The size of the air particles is too small.
The air particles do not have space between them.
The model does not show the direction in which the air particles move.
For you to hear sound, which events must take place third?
Your eardrum vibrates when the sound wave reaches it.
An object vibrates to make a sound.
Air particles vibrate as sound moves through the air

After research, Tony learned what is displayed in the chart. What can Tony conclude about how air temperature affects the speed of sound?
When air temperature increases, the speed of sound decreases.
When air temperature increases, the speed of sound increases.
Air temperature has no effect on the speed of sound.
When air temperature increases, the speed of sound remains the same.
The phone will ____________________ because _________________________.
ring at a higher pitch,
there are more air particles
ring at a lower pitch,
there are more air particles
will not make a sound,
there are no air particles to transfer energy
ring at a regular pitch,
the air particles have more energy
What is the best explanation for why the rubber bands had a different pitch?
The thinner rubber bands were longer.
The thicker rubber bands had more thermal energy.
The rubber bands vibrated at different speeds.
Sound traveled slower through thinner rubber bands.
Sound is a form of __________ energy produced and transmitted by __________ matter.
mechanical, musical
radiant,
vibrating
mechanical, vibrating
thermal,
musical
In the model, what is traveling from the speaker through the air and to the ear?
sound particles
negatively charged particles
music notes
energy
What would be a reasonable explanation of why sound travels faster through glass than gold?
Glass transfers energy better than gold.
Glass particles are further apart than gold particles.
Glass is gas but gold is solid.
Gold particles are closer together than glass particles.
Which of the rubber bands transferred energy when the student pulled on it?
Rubber band A
Rubber band B
Rubber band C and rubber band D
All rubber bands
Which of the instrument does not vibrate strings to form sound?
What would be the best way to cause vibrations in the water xylophone?
Wrap a rubber band around each glass
Add water to each glass.
Rearrange the order of the glasses.
Tap the side of each glass with a spoon.
