Grade 4 Sound Quiz

Anika, Emma, and David are in a science class. Their teacher explains that when she strums a guitar, they can hear the sound because of what?

• Sound is a form of liquid that travels from the guitar to their ears.

• Sound is a form of solid that travels from the guitar to their ears.

• Sound is a type of light that travels from the guitar to their eyes.

• Sound is a form of energy produced by vibrations traveling through a medium, like air, from the guitar to their ears.

Liam, Scarlett, and Abigail are in a band. When Liam strums his guitar, how does the sound reach Scarlett and Abigail's ears?

• Through the vibration of particles in the air

• Through the movement of clouds in the sky

• By the rotation of the Earth

• Via the reflection of light off of surfaces

Rohan, Mia, and Grace are conducting a science experiment. They are trying to categorize different types of sounds. Can you help them identify the correct categories?

• Visible, invisible, and translucent

• Loud, soft, and medium

• Audible, inaudible, and ultrasonic

• High, low, and medium

During a music class, Aria was playing a musical instrument and Olivia noticed a change in the perceived frequency of the sound when Aria played different notes. What is this change referred to as?

• A type of tar used in construction

• The angle of a slope

• The act of throwing a ball by Aiden

• Pitch

Michael is studying waves in his physics class. He comes across a term 'frequency'. Luna explains it to him as the number of occurrences of a repeating event per unit of time. Abigail, however, gives a different explanation. Which of the following is Abigail's explanation?

• The distance between two points

• The speed of an object

• The amount of energy in a system

• Number of occurrences of a repeating event per unit of time

Priya, Abigail, and Aiden are packing for a camping trip. They are trying to figure out how much space their camping gear will take up in their backpacks. Which of the following best describes what they are trying to calculate?

• The weight of their camping gear

• The quantity of three-dimensional space enclosed by their backpacks

• The length of their camping gear

• The color of their camping gear

Aiden, Henry, and Anika are studying physics. They are experimenting with a pendulum and observing its swings. According to their observations, what would they call the maximum extent of the pendulum's swing or oscillation?

• They would call it the amplitude

• They would call it the distance between two points

• They would call it the angle of the wave

• They would call it the speed of sound in the medium

Mia, Abigail, and Aiden are in a science class. Their teacher asks, 'If you shout in a tunnel, what kind of waves does your voice produce?'

• Electromagnetic waves that travel through a vacuum

• Transverse waves that travel through a medium

• Standing waves that do not travel through a medium

• Longitudinal waves that travel through a medium

Liam, Grace, and James are in a science class. Their teacher asks them, 'How would you measure the sound of a rock concert you attended last night?'

• Using a sound level meter to measure decibels

• Estimating the sound level based on the volume of the rock band

• Counting the number of people who could hear the concert

• Using a ruler to measure the length of the sound waves at the concert

Anika, Aiden, and Ethan are conducting a science experiment to measure the speed of sound in air. If they use the correct equipment and method, what speed should they expect to measure?

• 343 meters per second

• 100 meters per second

• 500 meters per second

• 700 meters per second
