Goal: describe what a viewpoint conceals and avoid claiming an unseen feature is absent or changed. Proposed codes: AC9SFH01, AC9SFI03, AC9SFI05. Prepare: Model F, viewpoint-model, optional safe second real view if locally approved, Card 63.
- Source · 3 min. Label F FICTIONAL. For real plant work, adult approves any changed viewing place/access and records both actual views/dates; never require a child to move unsafely.
- Read · 4 min. Compare FRONT and SIDE in F. In the story, the grey paper panel hides a mark; it does not erase a real leaf.
- Model · 5 min. Teacher covers/uncover one broad fixed raised oval in a paper model and says “not visible from here” rather than “gone”.
- Child try · 7 min. Card 63 routes identify one visible, one hidden/unknown feature in the model or carefully compare two actual approved views if available, with access attribution.
- Check · 4 min. Present “I see two ovals from SIDE, so the plant lost one leaf.” Child corrects source/visibility and names a safer view needed.
- Exit · 2 min. Save a claim bounded to the actual view or MODEL ONLY.
