This question aligns with the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - investigation planning part. An investigation is a test to find out something. In this investigation, students test if vibrating (shaking) materials make sound. A good investigation plan has: question, materials, steps, and what to observe. Students should observe two things: does the object vibrate (shake/move)? Does it make sound? This plan tests a triangle. The steps are: hold the triangle by the string, tap it with the stick, watch and listen. The student should observe if the triangle shakes and if it rings. The correct answer says "It tests if vibrating can make sound from a triangle." which correctly identifies the investigation purpose is to test vibration-sound connection. This matches what the investigation plan is designed to show. A distractor like "It tests if ringing sound makes the triangle shake." is wrong because it reverses cause-effect. Students might choose this if they only focus on one part of investigation, don't understand purpose is to connect vibration to sound, think touching alone makes sound without vibration. Before investigation, ask "What do you think will happen?" After, ask "What did you see?" (vibration) and "What did you hear?" (sound). Connect the two: "When it shook, we heard sound." Do multiple examples (drum, rubber band, ruler) so students see pattern: vibration always makes sound. Help students focus on cause-effect: action (tap) → vibration (shake) → sound (hear). Watch for: students who only attend to one sense (just watching OR just listening) without connecting both observations.

This question tests understanding of 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically predicting investigation results. An investigation is a test to find out something. In this investigation, students test if vibrating (shaking) materials make sound. A good investigation plan has: question, materials, steps, and what to observe. Students should observe two things: does the object vibrate (shake/move)? Does it make sound? Yuki's plan tests a guitar string. The steps are: pluck string, watch and listen, then touch to stop it. Yuki should observe if the string shakes and if it makes sound. The correct answer says "She will see the string shake and hear sound" which correctly identifies both expected observations - the string vibrating (shaking) and making sound. This matches what the investigation plan is designed to show. Wrong answers like "She will hear sound, but the string will not move" are incorrect because they separate sound from vibration - guitar strings must vibrate to make sound. Students might choose this if they can't see the fast vibrations of a thin string, or think sound happens without movement. Before investigation, have students gently touch a quiet guitar string: "Is it moving? Making sound?" (no to both). After plucking, use slow-motion video or put paper on the string to make vibrations visible. The stopping step is powerful: "When we stop the shaking, what happens to the sound?" This clearly shows vibration and sound are connected.

This question tests understanding of 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically identifying investigation purpose. An investigation is a test to find out something. In this investigation, students test if vibrating (shaking) materials make sound. A good investigation plan has: question, materials, steps, and what to observe. Students should observe two things: does the object vibrate (shake/move)? Does it make sound? This plan tests a rubber band stretched between fingers. The steps are: hold rubber band stretched, pluck it, then watch and listen. The student should observe if the rubber band vibrates and if it makes sound. The correct answer says "It tests if vibrating makes sound from the rubber band" which correctly identifies the investigation purpose is to test the vibration-sound connection. This matches what the investigation plan is designed to show. Wrong answers like "It tests if a rubber band can stretch far" are incorrect because they focus on the wrong property - stretching instead of vibrating and making sound. Students might choose this if they get distracted by the setup steps rather than understanding the main purpose of connecting vibration to sound. Before investigation, ask "What are we trying to find out?" Point to the question in the plan. After, ask "What did the rubber band do?" (vibrated) and "What happened when it vibrated?" (made sound). Connect the two: "The vibrating rubber band made a twang sound." Do multiple examples so students see pattern: all vibrating things make sound. Help students focus on the investigation question, not just the materials or setup.

This question aligns with the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound, focusing on the investigation planning part. An investigation is a test to find out something. In this investigation, students test if vibrating (shaking) materials make sound. A good investigation plan has: question, materials, steps, and what to observe. Students should observe two things: does the object vibrate (shake/move)? Does it make sound? This specific investigation tests a ruler on a desk. The steps are: put the ruler on the edge, push down and let go, then watch and listen. You should observe if the ruler vibrates and if it makes sound. The correct answer says "It tests if vibrating things make sound" which correctly identifies the investigation purpose is to test vibration-sound connection. This matches what the investigation plan is designed to show. A distractor like "It tests if sound makes the ruler shake" is wrong because it reverses cause-effect. Students might choose this if they don't understand the purpose is to connect vibration to sound, think touching alone makes sound without vibration. Before investigation, ask "What do you think will happen?" After, ask "What did you see?" (vibration) and "What did you hear?" (sound). Connect the two: "When it shook, we heard sound." Do multiple examples (drum, rubber band, ruler) so students see pattern: vibration always makes sound. Help students focus on cause-effect: action (tap) → vibration (shake) → sound (hear).

Amir's plan tests a ruler. The steps are: put the ruler on the desk edge, hold it, push down the end, let go, watch and listen. Amir should observe if the ruler shakes and if it makes buzzing. The correct answer says "If vibrating things can make sound." which correctly identifies the investigation purpose is to test vibration-sound connection. This matches what the investigation plan is designed to show. A distractor like "If sound makes the ruler start to shake." is wrong because it reverses cause-effect. Students might choose this if they only focus on one part of investigation, don't understand purpose is to connect vibration to sound, think touching alone makes sound without vibration. Before investigation, ask "What do you think will happen?" After, ask "What did you see?" (vibration) and "What did you hear?" (sound). Connect the two: "When it shook, we heard sound."

A good investigation plan has: question, materials, steps, and what to observe. Students should observe two things: does the object vibrate (shake/move)? Does it make sound? Keisha's plan tests a guitar string. The steps are: pluck string, watch and listen, then touch to stop it. Keisha should observe the string vibrate and listen for sound. The correct answer says "Watch the string vibrate and listen for sound" which correctly identifies both observations needed to connect vibration with sound. This matches what the investigation plan is designed to show. Wrong answers like "Only watch the guitar body, not the string" are wrong because they direct attention to the wrong part - the string is what vibrates to make sound. Students might choose this if they don't understand which part to observe. Before investigation, point to the string: "This is what we'll watch." During investigation, guide observation: "See how the string moves back and forth? Hear the sound?" When touching stops both: "The vibration stopped, so the sound stopped too!"

Maya's plan tests a triangle. The steps are: hold the triangle by the string, tap it with the stick, watch and listen. Maya should observe if the triangle shakes and if it rings. The correct answer says "The triangle shakes and rings when Maya taps." which correctly identifies the expected result is vibration and sound. This matches what the investigation plan is designed to show. A distractor like "The triangle rings, but it does not shake." is wrong because it only mentions sound without vibration. Students might choose this if they only focus on one part of investigation, don't understand purpose is to connect vibration to sound, think touching alone makes sound without vibration. Before investigation, ask "What do you think will happen?" After, ask "What did you see?" (vibration) and "What did you hear?" (sound). Connect the two: "When it shook, we heard sound."

This question tests the skill 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound - specifically following investigation steps. An investigation is a test to find out something. In this investigation, students test if vibrating (shaking) materials make sound. A good investigation plan has: question, materials, steps, and what to observe. Students should observe two things: does the object vibrate (shake/move)? Does it make sound? Carlos's plan tests a ruler on a desk edge. The steps are: put ruler on edge, push down and let go, then watch and listen. Carlos should first put the ruler on the desk edge. The correct answer says "Put the ruler on the desk edge" which correctly identifies the first step in the investigation procedure. This matches what the investigation plan is designed to show. Wrong answers like "Listen for buzzing before you let it go" are wrong because they suggest doing steps out of order - you can't hear buzzing before making the ruler vibrate. Students might choose this if they don't understand that steps must be done in order. Before investigation, read steps together: "First we do this, then this." Practice following steps in order with other activities. Emphasize: "We can't skip ahead - each step prepares for the next one."

Jamal's plan tests a drum. The steps are: touch the drum top (it is still), tap the drum, look at the drum top and listen. Jamal should observe if the drum top shakes and if it makes boom. The correct answer says "Watch the drum top shake and listen for boom." which correctly identifies what to observe is both shaking and sound. This matches what the investigation plan is designed to show. A distractor like "Only listen for boom, do not watch." is wrong because it only mentions sound without vibration. Students might choose this if they only focus on one part of investigation, don't understand purpose is to connect vibration to sound, think touching alone makes sound without vibration.
