Goal: name one external mark in each of two paper figures and separate drawn feature from actual organism. Proposed codes: AC9SFU01 (model reasoning only), AC9SFH01, AC9SFI03. Prepare: complete N1–N4 source, four figures, Card 141.
- Source · 3 min. Say “These are my invented notebook drawings. They are not photographs or living things.” Set the actual-source line to REAL OBSERVATION NOT AVAILABLE unless a separately approved view occurs.
- View · 4 min. Show N1 and N3 in order. Read N1's three round-ended leaf marks and N3's two pointed ear marks without asking for species names.
- Model · 5 min. Point to a leaf outline and an ear outline: “Both are outside marks; they are not the same body part. A drawing shows only what was drawn.”
- Child try · 7 min. Card 141 routes identify one exact external mark on each picture and label both FICTIONAL MODEL; save child's own wording.
- Probe · 4 min. Ask, “Does the paper prove a real animal has those ears?” Accept “No, it is a puppet drawing,” then ask what genuine source would be needed.
- Exit · 2 min. Save two model marks plus source limit, not a real biological result.
