- Read about Chen. He tapped a drum; rice bounced. Why?
Answer: The drum's boom sound made the rice bounce.
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 - specifically the part where sound makes materials vibrate. Sound is vibrations traveling through air. When sound reaches other objects, the vibrations can make those objects vibrate too. We can see this when lightweight materials like paper, rice, sand, or water shake, bounce, or move because of sound, and loud sounds make bigger vibrations we can see more easily. In this story, Chen tapped a drum, which made boom sounds, and the sound vibrations traveled to the rice and made it bounce. This shows sound can make materials vibrate. The correct answer says "The drum's boom sound made the rice bounce." which identifies sound as the cause of the rice's vibration. This is correct - the boom made the rice bounce, as sound vibrations transfer to nearby materials. A distractor like "The rice bouncing made the drum boom loudly." is wrong because it reverses cause-effect. Students might choose this if they see two events but don't connect cause-effect. Do demonstrations students can see: put rice on drum and tap it, hold paper near speaker, watch water ripples near loud sound. Ask "What made the rice move?" Connect sound to movement. Try loud vs soft sounds - which makes more movement? Let students gently touch vibrating surface (table when drum plays on it) to feel sound vibrations. Explain: sound is invisible shaking air, when sound reaches other objects it can make them shake too. Watch for: students who only notice visible actions (tapping, touching) without connecting to sound's effect.

- Read about Chen. Quiet taps made little rice movement. Why?
Answer: The quiet drum sound made the rice move a little.
This question tests understanding of 1-PS4-1: Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate - specifically the sound makes materials vibrate part. Sound is vibrations traveling through air. Louder sounds make bigger vibrations, quieter sounds make smaller vibrations. We can SEE this difference when materials move more with loud sounds and less with quiet sounds. In this story, Chen tapped the drum quietly. This made a quiet drum sound. The quiet sound vibrations traveled to the rice and made it move just a little. This shows that quieter sounds make smaller vibrations. The correct answer says "The quiet drum sound made the rice move a little" which correctly identifies that quiet sound causes small movement. This is correct - quiet sounds make small vibrations that cause small movements. Answer C "The rice moved first and made the drum sound" is wrong because it reverses cause-effect. Students might choose this if they don't understand sound causes movement. Do demonstrations: tap drum softly and watch rice move a little, then tap loudly and see rice jump high. Ask "What's different?" Connect sound volume to movement size. This helps students see that sound strength affects how much things vibrate.
