Goal: describe an actually observed property of two approved broad objects and name the access/safety route. Proposed codes: AC9SFU03, AC9SFI02, AC9SFI05. Prepare: preflighted paper sheet and fabric square or local equivalents, source/date log, Card 2.
- Safety choice · 3 min. Offer look, agreed touch of a clean broad object, adult movement demonstration or pass; no unknown smell/taste.
- Source · 4 min. Record actual item identity and teacher-verified material label or UNKNOWN. Show both objects separately, without assuming surface feel from a picture.
- Model · 5 min. Teacher describes one feature they actually access (“this sheet has a straight edge”) and records whether that was sight/touch/report. Avoid “all fabric feels…” generalisation.
- Child try · 7 min. Child chooses art-table, book-cover or quiet-table route on Card 2 and compares one feature of two real objects under safe conditions. Adult scribes exact observation and child access route.
- Check · 4 min. Present “The fabric square must always bend more than paper.” Child says the claim requires a specific gentle try; if a try happened, name its conditions and result only for these items.
- Exit · 2 min. Share one question/observation with a consenting adult or privately record it; public peer sharing is optional.
