All questions

Question 1

Look at what Emma did. The ruler is still first. Then she lets go; it wiggles and buzzes. What did Emma see and hear?

  1. The ruler wiggles fast, and Emma hears a buzz. (correct answer)
  2. The ruler stays still, and Emma hears a buzz.
  3. Emma hears a buzz, and then the ruler wiggles.
  4. Emma sees the desk shake, and it makes the buzz.
Explanation: This question assesses the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - questioning part. When objects vibrate, which means they shake or move back and forth quickly, they create sound waves that we can hear. Vibration is like a fast wiggling motion, and we can often see it happening, such as with a plucked string or a shaking ruler. In this scenario, Emma lets go of the ruler, which was still before, causing it to wiggle fast and produce a buzz sound that she hears, showing vibration leads to sound. The correct answer says 'The ruler wiggles fast, and Emma hears a buzz' which shows the student understands that the ruler's vibration caused the sound she heard, correctly applying the concept that vibration generates sound. A distractor like 'Emma hears a buzz, and then the ruler wiggles' is wrong because it reverses the sequence, implying sound precedes vibration; students might choose this if they didn't observe the timing of events. To help students, conduct hands-on experiments like plucking a rubber band or tapping a drum, asking 'What do you see?' (shaking) and 'What do you hear?' (sound), then connect them: 'When it shakes, we hear sound; when shaking stops, sound stops.' Have students touch vibrating objects to feel the movement, and watch for those who describe what they hear but don't link it to the visible wiggling.

Question 2

Read about Jamal. The rubber band twangs. Why did it make a sound?

  1. Jamal smiled, and the rubber band made a sound.
  2. The rubber band moved back and forth and made sound. (correct answer)
  3. The rubber band was still when it made sound.
  4. The twang sound made the rubber band start moving.
Explanation: This question tests understanding of 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically questioning why sound occurs. When objects vibrate (shake, move back and forth quickly, wiggle), they make sound. Vibration means moving back and forth fast. We can see some vibrations like a rubber band moving. In this story, Jamal's rubber band made a twang sound. The rubber band moved back and forth and made this sound. This shows vibration makes sound. The correct answer says "The rubber band moved back and forth and made sound" which shows the student understands that the rubber band vibrating/moving back and forth caused the sound. This is what happens - vibration creates sound. An incorrect answer like "The rubber band was still when it made sound" is wrong because it states sound without explaining vibration - things must move to make sound. Students might choose this if they didn't connect vibration to sound. Help students by doing hands-on experiments - pluck a rubber band, tap a drum, use a ruler on desk edge. Have students gently touch vibrating objects to feel the vibration. Watch for: students who describe the action but don't observe or describe the vibration that causes sound.

Question 3

Read about Jamal. He plucks a rubber band. What caused the twang sound?

  1. The rubber band moved fast and made a twang sound. (correct answer)
  2. Jamal plucked the rubber band with his finger.
  3. The rubber band was still and made a twang sound.
  4. Jamal's finger made the twang sound by itself.
Explanation: This question tests understanding of 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically questioning what causes sound. When objects vibrate (shake, move back and forth quickly, wiggle), they make sound. Vibration means moving back and forth fast. We can see some vibrations like a ruler shaking or a guitar string moving. In this story, Jamal plucked the rubber band. The rubber band moved fast back and forth and made a twang sound. This shows vibration makes sound. The correct answer says "The rubber band moved fast and made a twang sound" which shows the student understands that the rubber band vibrating/moving fast caused the sound. This is what happens - vibration creates sound. An incorrect answer like "Jamal plucked the rubber band with his finger" is wrong because it doesn't mention vibration, it only describes the action that started the vibration. Students might choose this if they only noticed what Jamal did, not what happened to the rubber band. Help students by doing hands-on experiments - pluck a rubber band, tap a drum, use a ruler on desk edge. Ask "What do you see?" (shaking/moving) and "What do you hear?" (sound). Connect the two: "When it shakes, we hear sound. When shaking stops, sound stops."

Question 4

Read about Marcus and a guitar. He pulls a string; it moves back and forth and makes sound. What caused the sound?

  1. The string moves back and forth and makes the sound. (correct answer)
  2. Marcus looks at the guitar and hears a sound.
  3. The string stays still and makes the sound.
  4. The sound makes the string start moving back and forth.
Explanation: This question assesses the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - questioning part. When objects vibrate, which means they shake or move back and forth quickly, they create sound waves that we can hear. Vibration is like a fast wiggling motion, and we can often see it happening, such as with a plucked string or a shaking ruler. In this story, Marcus pulls the guitar string, causing it to move back and forth and produce sound, demonstrating the link between vibration and sound creation. The correct answer says 'The string moves back and forth and makes the sound' which shows the student understands that the string's vibration caused the sound, reflecting the correct scientific concept that vibration generates sound. A distractor like 'The sound makes the string start moving back and forth' is wrong because it reverses the cause-effect, suggesting sound initiates vibration; students might pick this if they only noticed the sound without connecting it to the movement. To help students, conduct hands-on experiments like plucking a rubber band or tapping a drum, asking 'What do you see?' (shaking) and 'What do you hear?' (sound), then connect them: 'When it shakes, we hear sound; when shaking stops, sound stops.' Have students touch vibrating objects to feel the movement, and watch for those who describe the pulling action but don't link the vibration to the resulting sound.

Question 5

Look at what Jamal did. He plucks a rubber band. It wiggles fast and makes a twang sound. What caused the twang sound?

  1. The rubber band wiggles fast and makes a twang sound. (correct answer)
  2. Jamal smiles and the rubber band makes a twang.
  3. The rubber band is still and makes a twang sound.
  4. The twang sound makes the rubber band wiggle fast.
Explanation: This question tests the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically the questioning part about what causes sound. When objects vibrate (shake, move back and forth quickly, wiggle), they make sound. Vibration means moving back and forth fast. We can see some vibrations like a rubber band wiggling when we pluck it. In this story, Jamal plucked the rubber band. The rubber band wiggled fast and made a twang sound. This shows vibration makes sound. The correct answer says "The rubber band wiggles fast and makes a twang sound" which shows the student understands that the rubber band vibrating/wiggling caused the sound. This is what happens - vibration creates sound. Wrong answers like "The twang sound makes the rubber band wiggle fast" are wrong because they reverse cause and effect - vibration causes sound, not the other way around. Students might choose this if they don't understand that vibration happens first, then sound. Help students by doing hands-on experiments - pluck a rubber band and watch it wiggle. Ask "What do you see?" (wiggling/moving) and "What do you hear?" (twang sound). Connect the two: "When it wiggles, we hear sound. When wiggling stops, sound stops."

Question 6

Look at what Jamal did. The rubber band was still before. He plucks it and it moves fast. What did Jamal see and hear?

  1. The rubber band moves fast and makes a twang sound. (correct answer)
  2. The rubber band is still and makes a twang sound.
  3. Jamal's fingers make the twang sound by touching.
  4. The rubber band moves fast and makes no sound.
Explanation: This question tests the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically questioning what students observe. When objects vibrate (shake, move back and forth quickly), they make sound. Vibration means moving back and forth fast. We can see vibrations like a rubber band moving when plucked. In this story, Jamal plucked a still rubber band. The rubber band moved fast and made a twang sound. This shows vibration makes sound. The correct answer says "The rubber band moves fast and makes a twang sound" which shows the student understands that Jamal saw the rubber band vibrating/moving fast and heard the sound it made. This is what happens - vibration creates sound. Wrong answers like "The rubber band is still and makes a twang sound" are wrong because objects must vibrate to make sound - they can't be still. Students might choose this if they don't understand that movement/vibration is necessary for sound. Help students compare still and vibrating objects. Pluck a rubber band and ask "What do you see?" (moving fast) and "What do you hear?" (twang). Then hold it still and ask the same questions (still, no sound).

Question 7

Look at what Maya did. She taps a tuning fork; the ends wiggle and hum. She touches it and it stops. Why did it hum?

  1. Maya touches the fork, and that makes the hum.
  2. The fork ends wiggle fast, and it makes a hum. (correct answer)
  3. The fork stays still, and it makes a hum sound.
  4. The hum sound makes the fork ends wiggle fast.
Explanation: This question assesses the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - questioning part. When objects vibrate, which means they shake or move back and forth quickly, they create sound waves that we can hear. Vibration is like a fast wiggling motion, and we can often see it happening, such as with a plucked string or a shaking ruler. In this scenario, Maya taps the tuning fork, making the ends wiggle fast and produce a hum, then touches it to stop both, showing vibration causes sound. The correct answer says 'The fork ends wiggle fast, and it makes a hum' which shows the student understands that the fork's vibration caused the sound, in line with the principle that vibration produces sound. A distractor like 'The hum sound makes the fork ends wiggle fast' is wrong because it reverses cause and effect; students might choose it if they focused on the sound without observing the prior vibration. To help students, conduct hands-on experiments like plucking a rubber band or tapping a drum, asking 'What do you see?' (shaking) and 'What do you hear?' (sound), then connect them: 'When it shakes, we hear sound; when shaking stops, sound stops.' Have students touch vibrating objects to feel the movement, and watch for those who mention the tap but overlook describing the wiggling that leads to the hum.

Question 8

Look at what Chen did. He taps a triangle. What caused the ringing sound?

  1. Chen tapped the triangle with a small stick.
  2. The triangle was still and made a ringing sound.
  3. The ringing sound made the triangle shake fast.
  4. The triangle shook and made a ringing sound. (correct answer)
Explanation: This question tests understanding of 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically questioning what causes sound. When objects vibrate (shake, move back and forth quickly, wiggle), they make sound. Vibration means moving back and forth fast. We can see some vibrations like a triangle shaking after being tapped. In this story, Chen tapped the triangle with a stick. The triangle shook fast and made a ringing sound. This shows vibration makes sound. The correct answer says "The triangle shook and made a ringing sound" which shows the student understands that the triangle vibrating/shaking caused the sound. This is what happens - vibration creates sound. An incorrect answer like "Chen tapped the triangle with a small stick" is wrong because it doesn't mention vibration, it only describes the action that started the vibration. Students might choose this if they only noticed what Chen did, not what happened to the triangle. Help students by doing hands-on experiments - pluck a rubber band, tap a drum, use a ruler on desk edge. Connect the two: "When it shakes, we hear sound. When shaking stops, sound stops." Have students gently touch vibrating objects to feel the vibration.

Question 9

Look at what Chen did. He taps a triangle. It shakes and makes a ring sound. What happened when Chen tapped it?

  1. Chen taps the triangle with a stick.
  2. The triangle shakes and makes a ringing sound. (correct answer)
  3. The triangle is still and makes a ringing sound.
  4. The ringing sound makes the triangle shake.
Explanation: This question tests the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically questioning what happens when objects are tapped. When objects vibrate (shake, move back and forth quickly), they make sound. Vibration means moving back and forth fast. We can see and feel vibrations like a triangle shaking when tapped. In this story, Chen tapped a triangle. The triangle shook and made a ring sound. This shows vibration makes sound. The correct answer says "The triangle shakes and makes a ringing sound" which shows the student understands that the triangle vibrating/shaking caused the sound. This is what happens - vibration creates sound. Wrong answers like "Chen taps the triangle with a stick" are wrong because they only describe the action but don't mention that the triangle's vibration causes the sound. Students might choose this if they only noticed what Chen did, not what happened to the triangle. Help students by tapping a real triangle and watching it shake. Ask "What do you see?" (shaking) and "What do you hear?" (ringing). Have students gently touch the vibrating triangle to feel it shake.

Question 10

Look at what Chen did. He grabs the triangle. What happened when he grabbed it?

  1. The triangle shook more, and the ring got louder.
  2. The triangle stopped shaking, and the ringing stopped. (correct answer)
  3. The triangle stayed still, but it kept ringing.
  4. Chen's hand rang, and the triangle stayed quiet.
Explanation: This question tests understanding of 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically questioning what happens when vibration stops. When objects vibrate (shake, move back and forth quickly, wiggle), they make sound. Vibration means moving back and forth fast. When vibration stops, sound stops too. In this story, Chen grabbed the triangle after tapping it. The triangle stopped shaking, and the ringing sound stopped too. This shows vibration makes sound, and no vibration means no sound. The correct answer says "The triangle stopped shaking, and the ringing stopped" which shows the student understands that stopping vibration stops sound. This is what happens - when vibration stops, sound stops. An incorrect answer like "The triangle stayed still, but it kept ringing" is wrong because it states sound without vibration, which is impossible. Students might choose this if they didn't understand that movement must continue for sound to continue. Help students by doing hands-on experiments - pluck a rubber band, tap a drum, use a ruler on desk edge. Show them: "When shaking stops, sound stops." Have students gently touch vibrating objects to feel the vibration stop.

Question 11

Look at what Emma did. The ruler buzzes. What did Emma see and hear?

  1. The ruler moved up and down, and she heard a buzz. (correct answer)
  2. The ruler was still, and she heard a buzz.
  3. The ruler moved up and down, but she heard nothing.
  4. Emma heard a buzz, so the ruler started moving.
Explanation: This question tests understanding of 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically questioning observations of vibration and sound together. When objects vibrate (shake, move back and forth quickly, wiggle), they make sound. Vibration means moving back and forth fast. We can see vibrations and hear sounds at the same time. In this story, Emma's ruler buzzed on the desk edge. The ruler moved up and down, and she heard a buzz sound. This shows vibration makes sound happening together. The correct answer says "The ruler moved up and down, and she heard a buzz" which shows the student understands seeing vibration and hearing sound happen together. This is what happens - we see vibration and hear sound at the same time. An incorrect answer like "The ruler was still, and she heard a buzz" is wrong because it states sound without vibration, which doesn't happen. Students might choose this if they only noticed the sound, not the movement. Help students by doing hands-on experiments - pluck a rubber band, tap a drum, use a ruler on desk edge. Ask "What do you see?" (shaking/moving) and "What do you hear?" (sound). Connect the two: "When it shakes, we hear sound."

Question 12

Look at what Marcus did. He plucks a guitar string. How did it make sound?

  1. Marcus plucked the string, and the guitar made sound.
  2. The string moved back and forth and made a sound. (correct answer)
  3. The string was still and made a sound.
  4. The sound made the string move back and forth.
Explanation: This question tests understanding of 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically questioning how sound is made. When objects vibrate (shake, move back and forth quickly, wiggle), they make sound. Vibration means moving back and forth fast. We can see some vibrations like a guitar string moving. In this story, Marcus plucked a guitar string. The string moved back and forth and made a sound. This shows vibration makes sound. The correct answer says "The string moved back and forth and made a sound" which shows the student understands that the string vibrating/moving back and forth caused the sound. This is what happens - vibration creates sound. An incorrect answer like "Marcus plucked the string, and the guitar made sound" is wrong because it doesn't mention vibration, it focuses on the action not the result. Students might choose this if they only noticed what Marcus did, not what happened to the string. Help students by doing hands-on experiments - pluck a rubber band, tap a drum, use a ruler on desk edge. Connect the two: "When it shakes, we hear sound. When shaking stops, sound stops." Have students gently touch vibrating objects to feel the vibration.

Question 13

Look at what Sofia did. She taps a drum. The drum top shakes and makes a boom. What made the boom sound?

  1. Sofia taps the drum with her hand.
  2. The drum is still and makes a boom sound.
  3. The drum top shakes back and forth and makes a boom. (correct answer)
  4. The boom sound makes the drum top shake.
Explanation: This question tests the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically questioning what makes sound. When objects vibrate (shake, move back and forth quickly), they make sound. Vibration means moving back and forth fast. We can see vibrations like a drum top shaking when we tap it. In this story, Sofia tapped the drum. The drum top shook back and forth and made a boom. This shows vibration makes sound. The correct answer says "The drum top shakes back and forth and makes a boom" which shows the student understands that the drum top vibrating/shaking caused the sound. This is what happens - vibration creates sound. Wrong answers like "Sofia taps the drum with her hand" are wrong because they only describe the action but don't explain that the drum's vibration causes the sound. Students might choose this if they only noticed what Sofia did, not what happened to the drum. Help students by tapping a real drum and watching the top shake. Ask "What do you see?" (shaking) and "What do you hear?" (boom). Put rice or sand on the drum to see it jump when the drum vibrates.

Question 14

Read about Sofia and a drum. She hits it gently. Why did it make sound?

  1. Sofia's hand made the boom sound by itself.
  2. The drum was still and made a boom sound.
  3. The drum top shook back and forth and made a boom. (correct answer)
  4. The drum made a boom sound, but nothing moved.
Explanation: This question tests understanding of 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically questioning why sound occurs. When objects vibrate (shake, move back and forth quickly, wiggle), they make sound. Vibration means moving back and forth fast. We can see some vibrations like a drum skin shaking. In this story, Sofia hit the drum gently. The drum top shook back and forth and made a boom sound. This shows vibration makes sound. The correct answer says "The drum top shook back and forth and made a boom" which shows the student understands that the drum top vibrating/shaking caused the sound. This is what happens - vibration creates sound. An incorrect answer like "The drum was still and made a boom sound" is wrong because it states sound without explaining vibration - things must move to make sound. Students might choose this if they didn't connect vibration to sound. Help students by doing hands-on experiments - pluck a rubber band, tap a drum, use a ruler on desk edge. Ask "What do you see?" (shaking/moving) and "What do you hear?" (sound). Watch for: students who describe the action (hitting, touching) but don't observe or describe the vibration that causes sound.

Question 15

Read about Maya. She taps a tuning fork. What made the humming sound?

  1. The tuning fork ends wiggled fast and made a hum. (correct answer)
  2. Maya touched the tuning fork with her hand.
  3. The tuning fork was still and made a humming sound.
  4. The humming sound made the tuning fork wiggle fast.
Explanation: This question tests understanding of 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically questioning what makes sound. When objects vibrate (shake, move back and forth quickly, wiggle), they make sound. Vibration means moving back and forth fast. We can see some vibrations like tuning fork ends wiggling. In this story, Maya tapped a tuning fork. The tuning fork ends wiggled fast and made a humming sound. This shows vibration makes sound. The correct answer says "The tuning fork ends wiggled fast and made a hum" which shows the student understands that the tuning fork vibrating/wiggling caused the sound. This is what happens - vibration creates sound. An incorrect answer like "The humming sound made the tuning fork wiggle fast" is wrong because it reverses cause-effect - vibration causes sound, not the other way around. Students might choose this if they didn't understand that movement comes first, then sound. Help students by doing hands-on experiments - pluck a rubber band, tap a drum, use a ruler on desk edge. Ask "What do you see?" (shaking/moving) and "What do you hear?" (sound). Watch for: students who describe the action (hitting, touching) but don't observe or describe the vibration that causes sound.

Question 16

Look at what Chen did. He taps the triangle; it shakes and rings. After it stops shaking, the ring stops too. What happened when it stopped shaking?

  1. The ringing stops when the triangle stops shaking. (correct answer)
  2. The ringing starts when the triangle stops shaking.
  3. Chen's hand keeps ringing when the triangle is still.
  4. The triangle shakes, but it does not make sound.
Explanation: This question assesses the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - questioning part. When objects vibrate, which means they shake or move back and forth quickly, they create sound waves that we can hear. Vibration is like a fast wiggling motion, and we can often see it happening, such as with a plucked string or a shaking ruler. In this scenario, Chen taps the triangle, making it shake and ring, and when it stops shaking, the ringing stops too, showing that sound ends when vibration ceases. The correct answer says 'The ringing stops when the triangle stops shaking' which shows the student understands that the absence of vibration stops the sound, correctly linking vibration to sound production. A distractor like 'The ringing starts when the triangle stops shaking' is wrong because it incorrectly suggests sound begins without vibration; students might choose this if they misunderstood the sequence of events. To help students, conduct hands-on experiments like plucking a rubber band or tapping a drum, asking 'What do you see?' (shaking) and 'What do you hear?' (sound), then connect them: 'When it shakes, we hear sound; when shaking stops, sound stops.' Have students touch vibrating objects to feel the movement, and watch for those who observe the tap but miss how the stopping of shaking leads to silence.

Question 17

Look at what Chen did. He taps a triangle; it shakes and rings. Then he grabs it and it stops. What happened when Chen grabbed it?

  1. The triangle shakes more and the ringing gets louder.
  2. The triangle stays still and the ringing stops. (correct answer)
  3. Chen's hand rings loudly while the triangle stays still.
  4. The ringing makes the triangle start shaking fast.
Explanation: This question assesses the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - questioning part. When objects vibrate, which means they shake or move back and forth quickly, they create sound waves that we can hear. Vibration is like a fast wiggling motion, and we can often see it happening, such as with a plucked string or a shaking ruler. In this scenario, Chen taps the triangle, making it shake and ring, then grabs it, causing both the shaking and ringing to stop, illustrating that stopping vibration ends the sound. The correct answer says 'The triangle stays still and the ringing stops' which shows the student understands that without vibration, there is no sound, consistent with the principle that vibration is necessary for sound production. A distractor like 'The ringing makes the triangle start shaking fast' is wrong because it reverses cause and effect, claiming sound causes vibration; students might choose this if they didn't notice the sequence of stopping vibration leading to no sound. To help students, conduct hands-on experiments like plucking a rubber band or tapping a drum, asking 'What do you see?' (shaking) and 'What do you hear?' (sound), then connect them: 'When it shakes, we hear sound; when shaking stops, sound stops.' Have students touch vibrating objects to feel the movement, and watch for those who focus on the initial tap but miss how stopping the vibration stops the sound.

Question 18

Read about Marcus and a guitar string. Before, it is still and quiet. He pulls and lets go; it moves and makes sound. What happened when Marcus let go?

  1. The string moves back and forth and makes a sound. (correct answer)
  2. The string stays still and makes a sound.
  3. Marcus's hand makes the sound, not the string.
  4. The sound makes the string stop moving right away.
Explanation: This question assesses the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - questioning part. When objects vibrate, which means they shake or move back and forth quickly, they create sound waves that we can hear. Vibration is like a fast wiggling motion, and we can often see it happening, such as with a plucked string or a shaking ruler. In this story, the guitar string is still and quiet before Marcus pulls and lets go, then it moves back and forth and makes sound, illustrating vibration causing sound. The correct answer says 'The string moves back and forth and makes a sound' which shows the student understands that the string's vibration caused the sound, aligning with the principle that vibration generates sound. A distractor like 'The sound makes the string stop moving right away' is wrong because it incorrectly implies sound stops the vibration instead of being produced by it; students might select this if they didn't connect the movement to the sound. To help students, conduct hands-on experiments like plucking a rubber band or tapping a drum, asking 'What do you see?' (shaking) and 'What do you hear?' (sound), then connect them: 'When it shakes, we hear sound; when shaking stops, sound stops.' Have students touch vibrating objects to feel the movement, and watch for those who describe the pulling but overlook the back-and-forth motion producing the sound.

Question 19

Look at what Jamal did. He plucks a rubber band; it wiggles fast and makes a twang sound. What made the twang sound?

  1. The rubber band wiggles fast and makes the twang sound. (correct answer)
  2. Jamal's fingers make the twang sound by touching.
  3. The rubber band stays still and makes the twang sound.
  4. The twang sound makes the rubber band wiggle fast.
Explanation: This question assesses the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - questioning part. When objects vibrate, which means they shake or move back and forth quickly, they create sound waves that we can hear. Vibration is like a fast wiggling motion, and we can often see it happening, such as with a plucked string or a shaking ruler. In this scenario, Jamal plucks the rubber band, causing it to wiggle fast and produce a twang sound, demonstrating how vibration leads to sound. The correct answer says 'The rubber band wiggles fast and makes the twang sound' which shows the student understands that the rubber band's vibration caused the sound, aligning with the scientific principle that vibration creates sound. A distractor like 'The twang sound makes the rubber band wiggle fast' is wrong because it reverses the cause-effect relationship, suggesting sound causes vibration instead of the other way around; students might choose this if they didn't connect the sequence of events properly. To help students, conduct hands-on experiments like plucking a rubber band or tapping a drum, asking 'What do you see?' (shaking) and 'What do you hear?' (sound), then connect them: 'When it shakes, we hear sound; when shaking stops, sound stops.' Have students touch vibrating objects to feel the movement, and watch for those who focus on the action like plucking but miss describing the vibration that produces the sound.

Question 20

Read about Sofia and her drum. She touches it. What happened when she touched it?

  1. The drum shook more, and the boom got louder.
  2. The drum stayed still, but the boom kept going.
  3. The drum stopped shaking, and the sound stopped too. (correct answer)
  4. Sofia's hand made the boom sound without the drum.
Explanation: This question tests understanding of 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically questioning what happens when vibration stops. When objects vibrate (shake, move back and forth quickly, wiggle), they make sound. Vibration means moving back and forth fast. When vibration stops, sound stops too. In this story, Sofia touched her drum after hitting it. The drum stopped shaking, and the boom sound stopped too. This shows vibration makes sound, and no vibration means no sound. The correct answer says "The drum stopped shaking, and the sound stopped too" which shows the student understands that stopping vibration stops sound. This is what happens - when vibration stops, sound stops. An incorrect answer like "The drum stayed still, but the boom kept going" is wrong because it states sound without vibration, which is impossible. Students might choose this if they didn't connect vibration to sound. Help students by doing hands-on experiments - pluck a rubber band, tap a drum, use a ruler on desk edge. Ask "What do you see?" (shaking/moving) and "What do you hear?" (sound). Show them: "When shaking stops, sound stops."
