Sound Makes Materials Vibrate - 1st Grade Science

Which option is a correct observation statement: 'The plastic wrap ____ when sound is made.'?

vibrates. Sound waves from below cause the wrap to move.
Which statement is correct: Louder sounds usually cause stronger vibrations or weaker vibrations?

Louder sounds usually cause stronger vibrations. More sound energy creates bigger movements.
Which choice describes softer sound: larger vibrations or smaller vibrations?

Smaller vibrations. Less energy creates gentler movements in materials.
Which option is the best tool to observe vibration from sound on a surface: rice grains, a magnet, or a leaf?

Rice grains. Light grains jump and dance when sound vibrations reach them.
What is the name of the vibrating part of a drum that makes the sound?

The drumhead. This stretched surface vibrates when hit.
Which part of a sound source moves to create sound: the vibrating part or the still part?

The vibrating part creates the sound. Still parts don't move to produce sound waves.
Which choice describes louder sound: smaller vibrations or larger vibrations?

Larger vibrations. More energy creates bigger movements in materials.
What happens to nearby materials when a sound wave hits them?

They can vibrate back and forth. Sound waves transfer energy that makes materials move.
Choose the correct conclusion: If a ruler on a desk is plucked and the paper nearby shakes, sound caused what?

Sound made the paper vibrate. Sound waves from the ruler made paper move.
What word names the back-and-forth motion of a material caused by sound?

Vibration. Sound causes materials to move rapidly back and forth.
Identify the vibrating material in this setup: A loudspeaker plays music and a balloon held near it shakes.

The balloon surface. Sound waves from the speaker make the balloon move.
Identify the sense you use to detect sound made by vibrations.

Hearing. Ears detect sound waves from vibrations.
Which option best completes the idea: Softer sounds usually make nearby materials vibrate more or less?

Less. Weaker sound waves create smaller vibrations.
Identify what is vibrating when a speaker plays music: the speaker cone or the speaker case only.

The speaker cone. The cone moves back and forth to push air and create sound.
Which option best completes the idea: Louder sounds usually make nearby materials vibrate more or less?

More. Stronger sound waves create bigger vibrations.
Which option describes cause and effect correctly: "Vibrations make sound" or "Sound makes vibrations"?

Vibrations make sound. Objects must vibrate first to create sound waves.
Which observation shows that sound made a material vibrate: rice on plastic wrap jumps, or rice stays still?

Rice on plastic wrap jumps. Sound waves make the plastic vibrate, moving the rice.
Identify the best description: When you touch your throat while humming, what do you feel?

Vibrations in your throat. Your vocal cords vibrate to make sound when humming.
Which part of a drum moves (vibrates) when you hit the drum to make a sound?

The drumhead (stretched surface). Sound waves from the impact make the drumhead move back and forth.
Which option correctly completes this idea: Sound can make other materials ____.

vibrate. Sound waves transfer energy that causes movement.
Which option is a correct observation of vibration: "I see it move" or "I see no movement"?

"I see it move.". Seeing movement confirms vibration is happening.
Identify the part of a drum that vibrates to make sound when it is struck.

The drumhead. The stretched surface vibrates when hit to create sound.
Identify the vibrating material in this setup: You hum while holding your hand on your throat.

Your vocal cords (throat area). Humming creates vibrations you can feel in your throat.
Which observation best shows vibration: a ruler shaking, a ruler changing color, or a ruler growing?

A ruler shaking. Shaking shows the back-and-forth motion of vibration.
Which material can sound travel through: air, water, and solids, or only air?

Air, water, and solids. Sound waves can travel through any type of matter.
Which observation best shows vibration: a still object, or an object shaking slightly?

An object shaking slightly. Vibrating objects move back and forth repeatedly.
What is the best description of what happens to a paper cup when you speak into it?

The cup vibrates as sound waves hit it. Your voice creates sound waves that vibrate the cup.
What should you observe if you place plastic wrap over a bowl and make a loud sound nearby?

The plastic wrap vibrates (moves up and down). Sound waves cause the thin material to move.
Identify the sense you use to detect vibration by touching an object near a sound source.

Touch. Feeling lets you detect physical movement.
Which option best describes what you should see on water in a cup when a strong sound happens nearby?

Small ripples because the surface vibrates. Sound waves hitting water create visible vibrations.
What is sound in science when you describe how it affects objects?

Sound is a vibration that travels through matter. Vibrations move through materials as waves.
Which statement is correct: If you move farther from a sound source, vibrations in nearby materials usually increase or decrease?

They usually decrease. Sound energy weakens with distance traveled.
What should you observe if you hold a tissue near a speaker playing music loudly?

The tissue flutters because the air vibrates. Sound waves in air make lightweight materials move.
Which option is the correct observation: A ruler over a desk edge is plucked and makes sound because it ____.

vibrates. The ruler's vibrations create sound waves in the air.
Which sense is most used to detect vibration from sound: hearing or taste?

Hearing. Our ears detect sound vibrations in the air.
Which option best shows sound causing vibration: a drumhead moves when hit, or a drumhead never moves?

A drumhead moves when hit. The drum surface vibrates to create sound waves.
Which option is the correct cause-and-effect: 'Sound causes the paper to ____.'?

vibrate. Sound energy transfers to the paper, causing movement.
Which option best describes how sound can make another object move: push, pull, or vibration?

Vibration. Sound waves cause back-and-forth motion, not one-way forces.
Which option is a correct observation when you touch a vibrating object: "I feel buzzing" or "I feel nothing"?

"I feel buzzing.". Vibrations create a buzzing sensation when touched.
Choose the word that correctly completes the claim: 'If the sound stops, the vibration usually ____.'

stops. Sound and vibration are connected - one causes the other.
Identify the vibrating material in this setup: A tuning fork touches a cup of water and ripples form.

The tuning fork. The fork's vibrations transfer to water, creating ripples.
Identify the part of a guitar that vibrates to make sound when it is plucked.

The strings. Plucking makes strings vibrate to produce sound.
What is the name of the vibrating part of a guitar that makes the sound?

The string. Plucked strings vibrate to create sound waves.
Which part of a guitar vibrates to produce sound when the string is plucked?

The guitar string. Plucking creates vibrations that produce sound waves.
Which option best describes your throat when you hum: it vibrates or it does not vibrate?

It vibrates. Vocal cords vibrate to produce humming sounds.
Which statement correctly connects vibration to hearing: Your ears detect vibrations or colors?

Your ears detect vibrations. Your eardrums vibrate when sound waves reach them.
Which option best shows sound traveling through a solid: you hear a tap through a table, or you see light through it?

You hear a tap through a table. Sound vibrations travel through the solid table material.
Identify the sense you use to observe vibration when you see rice jump on plastic wrap.

Sight. You can see materials move when sound waves hit them.
Identify what is vibrating when you hear a bell ring after it is struck.

The bell metal. Striking causes the metal to vibrate and produce sound.
Which option is a correct example of sound making material vibrate: drumhead shaking or drumhead staying still?

Drumhead shaking. Sound waves make the drum surface move.
Identify the best conclusion: If a speaker plays music and a balloon held near it shakes, what is happening?

The balloon is vibrating from the sound. Sound waves from speaker cause balloon movement.
Identify the sense you use to observe vibration when you place a hand on a speaker.

Touch. You can feel vibrations as tingling or buzzing sensations.
What is vibration when you are describing what sound does to materials?

Vibration is fast back-and-forth movement. Movement repeats quickly in opposite directions.
