“Keep the frame steady. Move the marker or tell someone where it goes. Which notes can we compare?”

Your notes

Fictional frame F uses a tree-outline mark on its left and a low wall-outline across its base. At model time A an invented star triangle is above the left mark; at time B the same intact triangle is above the centre. F stays fixed. Record C uses a moved/different frame G and only says “above left”; no mapping between F/G is given. Compare A/B against F; C's word “left” does not by itself establish the same sky position. Star separations/real distances were not measured.

Pick one way

Route1 — Direct a paper observatory: Child gives the sequence for frame/triangle placement, then names what changed. This is actual paper modelling, not night observing. Route2 — Compare notebooks: Circle the named references in A/B/C; keep usable data and ask for the missing F/G relation before comparing C. Route3 — Make tactile or spoken instructions: Use broad raised paper edges if locally suitable or verbal frame labels; child supplies a fixed-reference instruction to a willing helper. No tactile-contact requirement.

You can ask a grown-up to read or write exactly what you tell them. Do a small useful part, rest or pass. A made-up note is not a real sky sighting.
