Flashcard 1: Which choice describes louder sound: smaller vibrations or larger vibrations?
Answer: Larger vibrations. More energy creates bigger movements in materials.
Flashcard 2: Which choice describes softer sound: larger vibrations or smaller vibrations?
Answer: Smaller vibrations. Less energy creates gentler movements in materials.
Flashcard 3: Which observation shows that sound made a material vibrate: rice on plastic wrap jumps, or rice stays still?
Answer: Rice on plastic wrap jumps. Sound waves make the plastic vibrate, moving the rice.
Flashcard 4: Which option best shows sound causing vibration: a drumhead moves when hit, or a drumhead never moves?
Answer: A drumhead moves when hit. The drum surface vibrates to create sound waves.
Flashcard 5: Which option best shows sound traveling through a solid: you hear a tap through a table, or you see light through it?
Answer: You hear a tap through a table. Sound vibrations travel through the solid table material.
Flashcard 6: Identify what is vibrating when a speaker plays music: the speaker cone or the speaker case only.
Answer: The speaker cone. The cone moves back and forth to push air and create sound.
Flashcard 7: Which observation best shows vibration: a still object, or an object shaking slightly?
Answer: An object shaking slightly. Vibrating objects move back and forth repeatedly.
Flashcard 8: Which sense is most used to detect vibration from sound: hearing or taste?
Answer: Hearing. Our ears detect sound vibrations in the air.
Flashcard 9: What happens to nearby materials when a sound wave hits them?
Answer: They can vibrate back and forth. Sound waves transfer energy that makes materials move.
Flashcard 10: Which material can sound travel through: air, water, and solids, or only air?
Answer: Air, water, and solids. Sound waves can travel through any type of matter.
Flashcard 11: What word names the back-and-forth motion of a material caused by sound?
Answer: Vibration. Sound causes materials to move rapidly back and forth.
Flashcard 12: Identify the sense you use to detect sound made by vibrations.
Answer: Hearing. Ears detect sound waves from vibrations.
Flashcard 13: What is vibration when you are describing what sound does to materials?
Answer: Vibration is fast back-and-forth movement. Movement repeats quickly in opposite directions.
Flashcard 14: What is sound in science when you describe how it affects objects?
Answer: Sound is a vibration that travels through matter. Vibrations move through materials as waves.
Flashcard 15: Which part of a sound source moves to create sound: the vibrating part or the still part?
Answer: The vibrating part creates the sound. Still parts don't move to produce sound waves.
Flashcard 16: Which option is a correct example of sound making material vibrate: drumhead shaking or drumhead staying still?
Answer: Drumhead shaking. Sound waves make the drum surface move.
Flashcard 17: What is the name of the vibrating part of a drum that makes the sound?
Answer: The drumhead. This stretched surface vibrates when hit.
Flashcard 18: What is the name of the vibrating part of a guitar that makes the sound?
Answer: The string. Plucked strings vibrate to create sound waves.
Flashcard 19: Which option best describes your throat when you hum: it vibrates or it does not vibrate?
Answer: It vibrates. Vocal cords vibrate to produce humming sounds.
Flashcard 20: Identify the sense you use to detect vibration by touching an object near a sound source.
Answer: Touch. Feeling lets you detect physical movement.
Flashcard 21: Which option is a correct observation of vibration: "I see it move" or "I see no movement"?
Answer: "I see it move.". Seeing movement confirms vibration is happening.
Flashcard 22: Which statement is correct: Louder sounds usually cause stronger vibrations or weaker vibrations?
Answer: Louder sounds usually cause stronger vibrations. More sound energy creates bigger movements.
Flashcard 23: Which option describes cause and effect correctly: "Vibrations make sound" or "Sound makes vibrations"?
Answer: Vibrations make sound. Objects must vibrate first to create sound waves.
Flashcard 24: Identify the best conclusion: If a speaker plays music and a balloon held near it shakes, what is happening?
Answer: The balloon is vibrating from the sound. Sound waves from speaker cause balloon movement.
Flashcard 25: Choose the correct conclusion: If a ruler on a desk is plucked and the paper nearby shakes, sound caused what?
Answer: Sound made the paper vibrate. Sound waves from the ruler made paper move.
Flashcard 26: Which option is a correct observation when you touch a vibrating object: "I feel buzzing" or "I feel nothing"?
Answer: "I feel buzzing.". Vibrations create a buzzing sensation when touched.
Flashcard 27: Identify the part of a guitar that vibrates to make sound when it is plucked.
Answer: The strings. Plucking makes strings vibrate to produce sound.
Flashcard 28: Which observation best shows vibration: a ruler shaking, a ruler changing color, or a ruler growing?
Answer: A ruler shaking. Shaking shows the back-and-forth motion of vibration.
Flashcard 29: Which statement correctly connects vibration to hearing: Your ears detect vibrations or colors?
Answer: Your ears detect vibrations. Your eardrums vibrate when sound waves reach them.
Flashcard 30: Which option best describes what you should see on water in a cup when a strong sound happens nearby?
Answer: Small ripples because the surface vibrates. Sound waves hitting water create visible vibrations.
