Question 1

The sound happened because the guitar was in a music room.
Every time the string moved, sound happened; stopping the string stopped sound too. (correct answer)
Touching the string made it quieter because fingers are soft.
The musical sound made the string move back and forth.

Explanation: This question tests 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times (every time the string vibrates, it makes sound), that's strong evidence. The pattern in observations helps us explain: vibrating makes sound. Keisha observed that when she plucked the guitar string, she saw it move back and forth fast and heard a musical sound. She also observed that when she touched the string, it stopped moving and the sound stopped too. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "Every time the string moved, sound happened; stopping the string stopped sound too" which uses Keisha's observations as evidence. This answer identifies the pattern (every time moving then sound, when stopped moving then stopped sound) which proves vibration causes sound. The observations support the explanation. An incorrect answer like "The musical sound made the string move back and forth" is wrong because it reverses cause-effect - vibration causes sound, not the other way around. Students might choose this if they don't understand cause-effect relationships and think they can see sound making things move. After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the string moved, we heard sound - the moving MAKES the sound." Use stop-evidence: "When we stopped the moving, sound stopped too - this shows moving causes sound." Practice multiple trials to see patterns. Chart observations: [Trial 1: move? sound?] [Trial 2: move? sound?] to visualize pattern.

Question 2

Read about Keisha. She plucked a guitar string and saw it move fast. She heard music. When she touched the string, it stopped moving and the sound stopped. Why does Keisha think moving makes sound?

Keisha saw the string move, so guitars always make music sounds.
Keisha found evidence: when the string stopped moving, the sound stopped too. (correct answer)
Keisha found evidence: the guitar was brown and had six strings.
Keisha found evidence: plucking the string made sound because her finger was strong.

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 - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times (every time the drum shakes, it makes sound), that's strong evidence. The pattern in observations helps us explain: vibrating makes sound. Keisha observed that she saw the string move fast and heard music. She also observed that when she touched the string, it stopped moving and the sound stopped. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "Keisha found evidence: when the string stopped moving, the sound stopped too." which uses Keisha's observations as evidence. This answer identifies the pattern (when X stopped, Y stopped) which proves vibration causes sound. The observations support the explanation. A generalization error like "Keisha saw the string move, so guitars always make music sounds." is wrong because it states observation without explaining connection and overgeneralizes without citing evidence from observations. Students might choose this if they can describe what happened but don't connect observations to explanation, don't recognize patterns as evidence, focus on action not vibration result, don't understand cause-effect. After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the drum shook, we heard sound - the shaking MAKES the sound." Use stop-evidence: "When we stopped the shaking, sound stopped too - this shows shaking causes sound." Practice multiple trials to see patterns. Chart observations: [Trial 1: shake? sound?] [Trial 2: shake? sound?] to visualize pattern. Watch for: students who can observe but can't yet explain patterns or use observations as evidence.

Question 3

Read about Emma. She hit a triangle with a stick. The triangle shook and rang. The ringing lasted a long time. When she grabbed the triangle, it stopped shaking and the ringing stopped too. What explains why the triangle made ringing?

The stick made the ringing sound all by itself.
When the triangle shook, it rang; grabbing stopped shaking and ringing together. (correct answer)
The triangle was shiny, so it rang longer.
She heard ringing once, so shaking must not matter.

Explanation: This question tests 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times (every time the triangle vibrates, it makes sound), that's strong evidence. The pattern in observations helps us explain: vibrating makes sound. Emma observed that when she hit the triangle with a stick, the triangle shook and rang. She also observed that when she grabbed the triangle, it stopped shaking and the ringing stopped too. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "When the triangle shook, it rang; grabbing stopped shaking and ringing together" which uses Emma's observations as evidence. This answer identifies the pattern (when shaking then ringing, when stopped shaking then stopped ringing) which proves vibration causes sound. The observations support the explanation. An incorrect answer like "She heard ringing once, so shaking must not matter" is wrong because it uses single observation not pattern and draws conclusion not supported by evidence - actually, the evidence shows shaking does matter. Students might choose this if they don't recognize patterns as evidence and make incorrect conclusions from limited observations. After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the triangle shook, we heard sound - the shaking MAKES the sound." Use stop-evidence: "When we stopped the shaking, sound stopped too - this shows shaking causes sound." Practice multiple trials to see patterns. Chart observations: [Trial 1: shake? sound?] [Trial 2: shake? sound?] to visualize pattern.

Question 4

The guitar was brown, so it made a musical sound.
When the string moved fast, she heard sound; when it stopped, sound stopped. (correct answer)
Plucking the string made sound because hands are loud.
The string was long, so it made music.

Explanation: This question tests 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times (every time the string vibrates, it makes sound), that's strong evidence. The pattern in observations helps us explain: vibrating makes sound. Keisha observed that when she plucked the guitar string, she saw it move back and forth fast and heard a musical sound. She also observed that when she touched the string, it stopped moving and the sound stopped too. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "When the string moved fast, she heard sound; when it stopped, sound stopped" which uses Keisha's observations as evidence. This answer identifies the pattern (when moving then sound, when stopped then no sound) which proves vibration causes sound. The observations support the explanation. An incorrect answer like "Plucking the string made sound because hands are loud" is wrong because it doesn't cite evidence from observations and incorrectly attributes sound to hands rather than string vibration. Students might choose this if they focus on their own action (plucking) rather than observing what happens to the string (vibrating) and don't recognize patterns as evidence. After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the string moved, we heard sound - the moving MAKES the sound." Use stop-evidence: "When we stopped the moving, sound stopped too - this shows moving causes sound." Practice multiple trials to see patterns. Chart observations: [Trial 1: move? sound?] [Trial 2: move? sound?] to visualize pattern.

Question 5

Read about Carlos. He pushed a ruler on the desk edge and let go. The ruler moved up and down very fast and made a buzzing sound. He tried three times. Every time the ruler vibrated, he heard buzzing. What evidence did Carlos find?

The ruler buzzed because desks are made of wood.
He pushed the ruler down, so pushing made the buzzing.
Each time the ruler moved fast, he heard buzzing at the same time. (correct answer)
The buzzing sound made the ruler move up and down.

Explanation: This question tests 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations.

He tried it three times and every time the ruler vibrated, he heard buzzing. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "Each time the ruler moved fast, he heard buzzing at the same time" which uses Carlos's observations as evidence. This answer identifies the pattern (each time moving fast then buzzing) which proves vibration causes sound. The observations support the explanation. An incorrect answer like "The buzzing sound made the ruler move up and down" is wrong because it reverses cause-effect - vibration causes sound, not the other way around. Students might choose this if they don't understand cause-effect relationships and think sound can make things move (which is possible but not what Carlos observed). After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the ruler moved fast, we heard sound - the moving MAKES the sound." Use stop-evidence: "When we stopped the moving, sound stopped too - this shows moving causes sound." Practice multiple trials to see patterns. Chart observations: [Trial 1: move? sound?] [Trial 2: move? sound?] to visualize pattern.

Question 6

Look at what Yuki found out. She stretched a rubber band and plucked it five times. Every time, the rubber band moved fast and made a twang sound. When the rubber band was still, no sound. How did Yuki know vibration causes sound?

Rubber bands are stretchy, so they always make twang sounds.
She plucked it, so plucking made the sound, not moving.
Every time it moved fast, she heard twang; still meant no sound. (correct answer)
The twang sound made the rubber band move fast.

Explanation: This question tests 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times (every time the rubber band vibrates, it makes sound), that's strong evidence. The pattern in observations helps us explain: vibrating makes sound. Yuki observed that when she plucked the rubber band five times, every time the rubber band moved fast and made a twang sound. She also observed that when the rubber band was still, there was no sound. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "Every time it moved fast, she heard twang; still meant no sound" which uses Yuki's observations as evidence. This answer identifies the pattern (every time moving fast then sound, when still then no sound) which proves vibration causes sound. The observations support the explanation. An incorrect answer like "The twang sound made the rubber band move fast" is wrong because it reverses cause-effect - vibration causes sound, not the other way around. Students might choose this if they don't understand cause-effect relationships and think they can see sound making things move. After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the rubber band moved fast, we heard sound - the moving MAKES the sound." Use stop-evidence: "When we stopped the moving, sound stopped too - this shows moving causes sound." Practice multiple trials to see patterns. Chart observations: [Trial 1: move? sound?] [Trial 2: move? sound?] to visualize pattern.

Question 7

Look at what Emma found out. She hit a triangle and it rang while it shook. When she grabbed it, both stopped together. How does Emma know shaking causes ringing?

The triangle was a new instrument, so it rang.
When the ringing stopped, the triangle stopped shaking.
Hitting the triangle made ringing because the stick was hard.
When she grabbed it, shaking stopped and ringing stopped together. (correct answer)

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, using observations as evidence to explain the relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times, like when the triangle shakes it makes ringing, that's strong evidence; the pattern in observations helps us explain that vibrating makes sound. Emma observed that when she hit the triangle, it shook and rang at the same time; she also observed that when she grabbed it, both the shaking and ringing stopped together. The correct answer says 'When she grabbed it, shaking stopped and ringing stopped together' which uses Emma's observations as evidence; this answer identifies the pattern of shaking and ringing happening together and stopping together, which proves vibration causes sound, and the observations support the explanation. A distractor like 'When the ringing stopped, the triangle stopped shaking' is wrong because it potentially reverses cause-effect and doesn't fully cite the grabbing observation as evidence; students might choose this if they don't understand cause-effect or can describe what happened but don't connect observations to explanation. After investigations, ask 'What did you see?' 'What did you hear?' 'Did it happen every time?' 'What happened when you stopped it?' Help students connect observations: 'Every time the triangle shook, we heard ringing - the shaking MAKES the sound.' Use stop-evidence: 'When we stopped the shaking, sound stopped too - this shows shaking causes sound.' Practice multiple trials to see patterns; chart observations like Trial 1: shake? sound? Trial 2: shake? sound? to visualize the pattern; watch for students who can observe but can't yet explain patterns or use observations as evidence.

Question 8

Look at what Yuki found out. She stretched a rubber band and plucked it five times. Every time it moved fast and made a twang. When it was still, no sound. What explains why the rubber band made twang?

The rubber band twanged because Yuki looked at it very closely.
The rubber band twanged because it vibrated every time she plucked it. (correct answer)
The rubber band twanged because rubber is stretchy and colorful.
The rubber band twanged because plucking is louder than shaking.

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 - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times (every time the drum shakes, it makes sound), that's strong evidence. The pattern in observations helps us explain: vibrating makes sound. Yuki observed that she saw the rubber band move fast and heard a twang. Yuki tried it five times and also observed that when it was still, no sound. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "The rubber band twanged because it vibrated every time she plucked it." which uses Yuki's observations as evidence. This answer identifies the pattern (every time X then Y) which proves vibration causes sound. The observations support the explanation. An irrelevant property error like "The rubber band twanged because rubber is stretchy and colorful." is wrong because it doesn't cite evidence from observations and focuses on attributes not related to vibration. Students might choose this if they can describe what happened but don't connect observations to explanation, don't recognize patterns as evidence, focus on action not vibration result, don't understand cause-effect. After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the drum shook, we heard sound - the shaking MAKES the sound." Use stop-evidence: "When we stopped the shaking, sound stopped too - this shows shaking causes sound." Practice multiple trials to see patterns. Chart observations: [Trial 1: shake? sound?] [Trial 2: shake? sound?] to visualize pattern. Watch for: students who can observe but can't yet explain patterns or use observations as evidence.

Question 9

Read about Carlos. He put a ruler on the desk edge and pushed it down. The ruler moved up and down very fast and made a buzzing sound. He tried three times. Every time the ruler vibrated, he heard buzzing. What pattern did Carlos observe?

Every time the ruler vibrated, he heard buzzing at the same time. (correct answer)
The ruler was yellow, and yellow rulers buzz more.
Pushing hard always makes buzzing, even without vibration.
He tried one time and heard buzzing once.

Explanation: This question tests 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times (every time the ruler vibrates, it makes sound), that's strong evidence. The pattern in observations helps us explain: vibrating makes sound. Carlos observed that when he pushed the ruler down and let go, the ruler moved up and down very fast and made a buzzing sound. He tried it three times and every time the ruler vibrated, he heard buzzing. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "Every time the ruler vibrated, he heard buzzing at the same time" which uses Carlos's observations as evidence. This answer identifies the pattern (every time vibrating then buzzing) which proves vibration causes sound. The observations support the explanation. An incorrect answer like "Pushing hard always makes buzzing, even without vibration" is wrong because it states observation without explaining connection and incorrectly suggests pushing alone causes sound without vibration. Students might choose this if they focus on the action (pushing) rather than the vibration result and don't understand that vibration is necessary for sound. After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the ruler vibrated, we heard sound - the vibrating MAKES the sound." Use stop-evidence: "When we stopped the vibrating, sound stopped too - this shows vibrating causes sound." Practice multiple trials to see patterns. Chart observations: [Trial 1: vibrate? sound?] [Trial 2: vibrate? sound?] to visualize pattern.

Question 10

Look at what Marcus observed. He tapped a tuning fork on the table. He saw the fork ends wiggle very fast and heard a humming sound. When he touched the fork, the wiggling stopped and the hum stopped. What was Marcus's evidence?

The tuning fork was metal, so it always hummed.
Tapping the table made the humming sound, not the fork.
He saw wiggling and heard hum; touching stopped both at the same time. (correct answer)
He liked the sound, so it kept humming.

Explanation: This question tests 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times (every time the tuning fork vibrates, it makes sound), that's strong evidence. The pattern in observations helps us explain: vibrating makes sound. Marcus observed that when he tapped the tuning fork on the table, he saw the fork ends wiggle very fast and heard a humming sound. He also observed that when he touched the fork, the wiggling stopped and the hum stopped. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "He saw wiggling and heard hum; touching stopped both at the same time" which uses Marcus's observations as evidence. This answer identifies the pattern (when wiggling then humming, when stopped wiggling then stopped humming) which proves vibration causes sound. The observations support the explanation. An incorrect answer like "Tapping the table made the humming sound, not the fork" is wrong because it doesn't cite correct evidence from observations - Marcus saw the fork wiggling, not the table, and the fork made the sound. Students might choose this if they focus on the initial action rather than observing what actually vibrates and don't understand cause-effect. After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the fork wiggled, we heard sound - the wiggling MAKES the sound." Use stop-evidence: "When we stopped the wiggling, sound stopped too - this shows wiggling causes sound." Practice multiple trials to see patterns. Chart observations: [Trial 1: wiggle? sound?] [Trial 2: wiggle? sound?] to visualize pattern.

Question 11

Read about Amir. He tapped a drum three times. Each time he saw the drum top shake fast and heard a boom. When he held the drum top still, no sound came out. Why did Amir think shaking makes the boom sound?

The drum was round, so it made a boom sound.
He hit the drum, and hitting always makes sound.
Every time the drum top shook, he heard boom; still meant no sound. (correct answer)
He heard a boom one time and stopped the test.

Explanation: This question tests 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations.

Amir observed that each time he tapped the drum, he saw the drum top shake fast and heard a boom sound. He tried it three times and also observed that when he held the drum top still, no sound came out. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "Every time the drum top shook, he heard boom; still meant no sound" which uses Amir's observations as evidence. This answer identifies the pattern (every time shaking then sound, when no shaking then no sound) which proves vibration causes sound. The observations support the explanation. An incorrect answer like "He hit the drum, and hitting always makes sound" is wrong because it doesn't cite evidence from observations and doesn't connect vibration to sound - it just states hitting causes sound without explaining why. Students might choose this if they focus on the action (hitting) rather than observing what happens to the drum (vibrating) and don't yet understand cause-effect relationships. After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the drum shook, we heard sound - the shaking MAKES the sound." Use stop-evidence: "When we stopped the shaking, sound stopped too - this shows shaking causes sound." Practice multiple trials to see patterns.

Question 12

Read about Amir. He tapped a drum three times. Each time he saw the drum top shake fast and heard a boom sound. When he held the drum top still, no sound came out. What did Amir's observations show?

The drum top shaking caused the boom sound each time. (correct answer)
Drums are big, so they always make boom sounds.
Holding the drum made it heavier than before.
The boom sound caused the drum top to shake.

Explanation: This question tests 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times (every time the drum vibrates, it makes sound), that's strong evidence. The pattern in observations helps us explain: vibrating makes sound. Amir observed that each time he tapped the drum (three times), he saw the drum top shake fast and heard a boom sound. He also observed that when he held the drum top still, no sound came out. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "The drum top shaking caused the boom sound each time" which uses Amir's observations as evidence. This answer identifies the pattern (every time shaking then boom sound) and correctly states the cause-effect relationship that vibration causes sound. The observations support the explanation. An incorrect answer like "The boom sound caused the drum top to shake" is wrong because it reverses cause-effect - vibration causes sound, not the other way around. Students might choose this if they don't understand cause-effect relationships and think sound can make things move (which is possible but not what Amir observed). After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the drum shook, we heard sound - the shaking MAKES the sound." Use stop-evidence: "When we stopped the shaking, sound stopped too - this shows shaking causes sound." Practice multiple trials to see patterns.

Question 13

Read about Amir. He tapped a drum three times; each time he saw the top shake fast and heard boom. When he held it still, no sound. What did Amir's observations show?

The drum made boom because the room was quiet.
Each time the drum shook, he heard boom; still drum made none. (correct answer)
He tapped three times, so tapping caused sound without shaking.
The drum top was tight, so it made a boom 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, using observations as evidence to explain the relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times, like every time the drum shakes it makes boom, that's strong evidence; the pattern in observations helps us explain that vibrating makes sound. Amir observed that each time he tapped the drum, he saw the top shake fast and heard boom, and he tried it three times; he also observed that when he held it still and stopped vibrating, no sound came out. The correct answer says 'Each time the drum shook, he heard boom; still drum made none' which uses Amir's observations as evidence; this answer identifies the pattern of every time it shook there was sound and when still there was none, which proves vibration causes sound, and the observations support the explanation. A distractor like 'He tapped three times, so tapping caused sound without shaking' is wrong because it states multiple actions but reverses cause-effect and doesn't cite evidence from the shaking observations; students might choose this if they don't understand cause-effect or focus on the action not the vibration result. After investigations, ask 'What did you see?' 'What did you hear?' 'Did it happen every time?' 'What happened when you stopped it?' Help students connect observations: 'Every time the drum shook, we heard boom - the shaking MAKES the sound.' Use stop-evidence: 'When we stopped the shaking, sound stopped too - this shows shaking causes sound.' Practice multiple trials to see patterns; chart observations like Trial 1: shake? sound? Trial 2: shake? sound? to visualize the pattern; watch for students who can observe but can't yet explain patterns or use observations as evidence.

Question 14

Look at what Keisha found out. She plucked a guitar string and saw it move back and forth fast. She heard music. When she touched it, sound stopped. Why does Keisha think moving makes sound?

The moving string made music; when she stopped it, the sound stopped. (correct answer)
The guitar body made the sound because it was big.
She plucked it, so plucking made music without the string moving.
She saw the string and heard music, but not at same time.

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, using observations as evidence to explain the relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times, like when the string moves it makes music, that's strong evidence; the pattern in observations helps us explain that vibrating makes sound. Keisha observed that when she plucked the guitar string, she saw it move back and forth fast and heard music; she also observed that when she touched it and stopped the movement, the sound stopped. The correct answer says 'The moving string made music; when she stopped it, the sound stopped' which uses Keisha's observations as evidence; this answer identifies the pattern of moving string caused music and when moving stopped so did the sound, which proves vibration causes sound, and the observations support the explanation. A distractor like 'She plucked it, so plucking made music without the string moving' is wrong because it reverses cause-effect and doesn't cite evidence from the movement observations; students might choose this if they don't understand cause-effect or focus on the action not the vibration result. After investigations, ask 'What did you see?' 'What did you hear?' 'Did it happen every time?' 'What happened when you stopped it?' Help students connect observations: 'Every time the string moved, we heard music - the moving MAKES the sound.' Use stop-evidence: 'When we stopped the moving, sound stopped too - this shows moving causes sound.' Practice multiple trials to see patterns; chart observations like Trial 1: move? sound?

Question 15

Look at what Emma found out. She hit a triangle and it shook and rang. When she grabbed it, it stopped shaking and the ringing stopped too. What was Emma's evidence?

Emma saw the triangle was metal, so metal always makes ringing.
Emma heard ringing, but she did not watch the triangle move.
Emma found evidence: when shaking stopped, the ringing stopped at the same time. (correct answer)
Emma found evidence: hitting harder made it louder, so the stick made 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 - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times (every time the drum shakes, it makes sound), that's strong evidence. The pattern in observations helps us explain: vibrating makes sound. Emma observed that she saw the triangle shake and heard ringing. She also observed that when she grabbed it, it stopped shaking and the ringing stopped too. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "Emma found evidence: when shaking stopped, the ringing stopped at the same time." which uses Emma's observations as evidence. This answer identifies the pattern (when X stopped, Y stopped) which proves vibration causes sound. The observations support the explanation. An irrelevant attribute error like "Emma saw the triangle was metal, so metal always makes ringing." is wrong because it doesn't cite evidence from observations and focuses on material properties not the vibration pattern. Students might choose this if they can describe what happened but don't connect observations to explanation, don't recognize patterns as evidence, focus on action not vibration result, don't understand cause-effect. After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the drum shook, we heard sound - the shaking MAKES the sound." Use stop-evidence: "When we stopped the shaking, sound stopped too - this shows shaking causes sound." Practice multiple trials to see patterns. Chart observations: [Trial 1: shake? sound?] [Trial 2: shake? sound?] to visualize pattern. Watch for: students who can observe but can't yet explain patterns or use observations as evidence.

Question 16

Look at what Carlos found out. He pushed a ruler and let go three times. Each time it moved up and down fast and he heard buzzing. What pattern did Carlos observe?

Every time the ruler vibrated, Carlos heard buzzing at the same time. (correct answer)
The desk was flat, so the ruler stayed still and quiet.
Carlos pushed the ruler, so pushing made buzzing without any shaking.
Carlos heard buzzing once, but the ruler did not move again.

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 - using observations as evidence to explain relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times (every time the drum shakes, it makes sound), that's strong evidence. The pattern in observations helps us explain: vibrating makes sound. Carlos observed that he saw the ruler move up and down fast and heard buzzing. Carlos tried it three times and also observed that each time it vibrated, he heard buzzing. This pattern shows vibration and sound are connected - vibration causes sound. The correct answer says "Every time the ruler vibrated, Carlos heard buzzing at the same time." which uses Carlos's observations as evidence. This answer identifies the pattern (every time X then Y) which proves vibration causes sound. The observations support the explanation. An irrelevant detail error like "The desk was flat, so the ruler stayed still and quiet." is wrong because it doesn't cite evidence from observations and focuses on unrelated properties instead of the vibration-sound connection. Students might choose this if they can describe what happened but don't connect observations to explanation, don't recognize patterns as evidence, focus on action not vibration result, don't understand cause-effect. After investigations, ask "What did you see?" "What did you hear?" "Did it happen every time?" "What happened when you stopped it?" Help students connect observations: "Every time the drum shook, we heard sound - the shaking MAKES the sound." Use stop-evidence: "When we stopped the shaking, sound stopped too - this shows shaking causes sound." Practice multiple trials to see patterns. Chart observations: [Trial 1: shake? sound?] [Trial 2: shake? sound?] to visualize pattern. Watch for: students who can observe but can't yet explain patterns or use observations as evidence.

Question 17

Read about Carlos. He pushed a ruler and let go three times. Every time it moved up and down fast, he heard buzzing. What pattern did Carlos observe?

Every time the ruler vibrated, he heard buzzing at the same time. (correct answer)
The ruler was long, so it made a buzzing sound.
Pushing the ruler made buzzing, not the ruler moving.
He heard buzzing once, so it always happens.

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, using observations as evidence to explain the relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times, like every time the ruler vibrates it makes buzzing, that's strong evidence; the pattern in observations helps us explain that vibrating makes sound. Carlos observed that every time he pushed the ruler and it moved up and down fast, he heard buzzing; he tried it three times and saw the same pattern each time. The correct answer says 'Every time the ruler vibrated, he heard buzzing at the same time' which uses Carlos's observations as evidence; this answer identifies the pattern of every time it vibrated there was buzzing, which proves vibration causes sound, and the observations support the explanation. A distractor like 'Pushing the ruler made buzzing, not the ruler moving' is wrong because it doesn't cite evidence from observations and reverses the focus from vibration to the initial action; students might choose this if they don't connect observations to explanation or focus on the action not the vibration result. After investigations, ask 'What did you see?' 'What did you hear?' 'Did it happen every time?' 'What happened when you stopped it?' Help students connect observations: 'Every time the ruler vibrated, we heard buzzing - the vibrating MAKES the sound.' Use stop-evidence: 'When we stopped the vibrating, sound stopped too - this shows vibrating causes sound.' Practice multiple trials to see patterns; chart observations like Trial 1: vibrate? sound? Trial 2: vibrate? sound? to visualize the pattern; watch for students who can observe but can't yet explain patterns or use observations as evidence.

Question 18

Read about Emma. She hit a triangle and it shook and rang. When she grabbed it, the shaking stopped and the ringing stopped. What explains why the triangle made sound?

The stick made the ringing sound because it hit the triangle.
The triangle rang because it was shiny and metal.
It rang once, so triangles always ring no matter what.
It rang when it shook; grabbed triangle stopped shaking and sound. (correct answer)

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, using observations as evidence to explain the relationship. Evidence is what we observe that helps us understand something. In science, we look for patterns in our observations. If we see the same thing happen many times, like when the triangle shakes it makes ringing, that's strong evidence; the pattern in observations helps us explain that vibrating makes sound. Emma observed that when she hit the triangle, it shook and she heard ringing; she also observed that when she grabbed it and stopped the shaking, the ringing stopped. The correct answer says 'It rang when it shook; grabbed triangle stopped shaking and sound' which uses Emma's observations as evidence; this answer identifies the pattern of when it shook there was sound and when shaking stopped so did the sound, which proves vibration causes sound, and the observations support the explanation. A distractor like 'It rang once, so triangles always ring no matter what' is wrong because it uses a single observation not a pattern and draws a conclusion not supported by evidence; students might choose this if they don't recognize patterns as evidence or don't understand cause-effect. After investigations, ask 'What did you see?' 'What did you hear?' 'Did it happen every time?' 'What happened when you stopped it?' Help students connect observations: 'Every time the triangle shook, we heard ringing - the shaking MAKES the sound.' Use stop-evidence: 'When we stopped the shaking, sound stopped too - this shows shaking causes sound.' Practice multiple trials to see patterns; chart observations like Trial 1: shake? sound? Trial 2: shake? sound? to visualize the pattern; watch for students who can observe but can't yet explain patterns or use observations as evidence.

Question 19

Read about Carlos. He tried a ruler three times. When it moved up and down fast, he heard buzzing every time. What evidence did Carlos find?

The ruler was on the desk edge, so it buzzed.
He pushed the ruler down, so pushing made the buzzing sound.
Every time it vibrated fast, he heard buzzing at the same time. (correct answer)
It buzzed once, so it always buzzes when you look.

The correct answer says 'Every time it vibrated fast, he heard buzzing at the same time' which uses Carlos's observations as evidence; this answer identifies the pattern of every time it vibrated there was buzzing, which proves vibration causes sound, and the observations support the explanation. A distractor like 'He pushed the ruler down, so pushing made the buzzing sound' is wrong because it focuses on the initial action without explaining the connection to vibration or citing evidence from the pattern; students might choose this if they focus on the action not the vibration result or don't connect observations to explanation. After investigations, ask 'What did you see?' 'What did you hear?' 'Did it happen every time?' 'What happened when you stopped it?' Help students connect observations: 'Every time the ruler vibrated, we heard buzzing - the vibrating MAKES the sound.'

Question 20

Look at what Keisha found out. She plucked a guitar string and saw it move fast. She heard music. When she touched the string, it stopped moving and the sound stopped. What evidence did Keisha find?

The guitar was brown, so it made a musical sound.
When the string stopped moving, the sound stopped too. (correct answer)
Plucking the string made sound because fingers are loud.
She heard a musical sound one time after plucking.
