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.
