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?
He tapped three times, so tapping caused sound without shaking.
Each time the drum shook, he heard boom; still drum made none.
The drum top was tight, so it made a boom sound.
The drum made boom because the room was quiet.
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.
Look at what Keisha found out. She plucked a guitar string and saw it move back and forth fast. She heard a musical sound. When she touched the string, it stopped moving and the sound stopped too. What did Keisha's observations show?
The musical sound made the string move back and forth.
Touching the string made it quieter because fingers are soft.
Every time the string moved, sound happened; stopping the string stopped sound too.
The sound happened because the guitar was in a music room.

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

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: hitting harder made it louder, so the stick made sound.
Emma found evidence: when shaking stopped, the ringing stopped at the same time.

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.

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

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

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."

Look at what Keisha found out. She plucked a guitar string and saw it move back and forth fast. She heard a musical sound. When she touched the string, it stopped moving and the sound stopped too. What evidence did Keisha find?
The string was long, so it made music.
Plucking the string made sound because hands are loud.
When the string moved fast, she heard sound; when it stopped, sound stopped.
The guitar was brown, so it made a musical sound.

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."

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

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.
The buzzing sound made the ruler move up and down.
He pushed the ruler down, so pushing made the buzzing.
Each time the ruler moved fast, he heard buzzing at the same time.

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