Teacher draft, 29 September 2026. Week 15 asks, “What can one optional, very gentle tap tell us about this verified broad material in this setup?” Week 16 asks, “What can we observe when the same broad card has an added approved layer?” Children make predictions, keep source/conditions visible and accept “not discernible” as a result. This is a materials inquiry under AC9SFU03, separate from the Week 15 original music composition, the Week 16 dry design station, and the separate mathematics capacity comparison. A rhythm performance, dry design trial or paper sound symbol is not itself a Science material observation.
Start with ten distinct timed 25-minute scripts, complete original source models and safe local protocol, 30 flexible same-target routes, 20 worked context swaps, ten optional family bridges, and two fresh teacher-held formative checks with separate keys. Six original A4 SVG/PDF aids have exact linear text and broad tactile alternatives:
| Aid | Use | |
|---|---|---|
| Quiet source gate | Safety, consent and source | |
| Paper sound model | Diagram cannot supply a sound | |
| Ask and predict | Before an optional real check | |
| One-action log | Exact observed/reported response | |
| Layer comparison | Same card, layer added, limits | |
| Explain and next | Source-bounded idea/next step |
Quiet is the default. An adult checks school approval, material identity or UNKNOWN, clean broad intact surfaces, non-latex/allergy safety, stable support, access and each child's comfort before any demonstration. No sudden, loud or repeated tapping, compulsory hearing, touch or performance. A child can choose paper-only reasoning or a neutral attributed adult report. If anyone needs a quiet room, do not produce the sound there; use the model. For every actual optional action, log local date, exact object/material/layer, support, gentle action and direct or attributed access. If no safe genuine action occurs, write REAL OBSERVATION NOT AVAILABLE; paper arrows/onomatopoeia are not audible evidence.
Exact pinned ACARA v9/QCAA crosswalk, source/rights ledger, desk QA and deterministic verifier/hash manifest make claims reviewable. National alignment is proposed and partial; local educator, accessibility, sensory safety and classroom review remain due.
