Materials

Full printed/readable source, blank paper guide and optional exact scribing/AAC; no required device/audio/material purchase.

Next teaching

If all motion becomes sound proof, use unrelated wind-up toy source notes: its wheels move but no bell report exists. Ask which extra source would be needed for a bell claim. Return to a different movement model.

Role

ordinary teaching/worked model; never independent held assessment evidence

Teacher moves

Read the caption no time measurement before stepping the frame.

Whole original context source and possible worked

C07 fictional toy-repair instructions show paper strip at centre, left, centre, right; caption “four selected positions, no time measurement”. Possible: “This is a movement model. It does not tell us the pitch, loudness or whether a listener heard a sound.” F2 fact card says incoming sound waves can make the eardrum vibrate; it is a reference account, not this child’s observation.
