Teacher draft, 29 September 2026. The question is: what changes when a broad flat object moves through a marked tabletop passage? Week 11 keeps one object and one passage while changing its orientation. Week 12 compares object width/shape and passage width. This extends the open-lane movement of Science Weeks 3–4. It complements the integrated Week 11 tool task and Week 12 sharing task; number arrangements and social fairness are separate learning goals, not Science evidence.
Start with ten distinct timed scripts, safe real-source gate and complete fictional models, 30 same-target access routes, 20 worked domain swaps, optional family conversations, and two fresh teacher-held checks with a separate key. Six original A4 SVG/PDF aids are linked below; exact linear text and tactile equivalents make every task usable without printing or a device.
| Aid | Purpose | |
|---|---|---|
| Safe passage | Adult setup and no-force boundaries | |
| Ask and predict | Question, source and before-try prediction | |
| Passage record | Actual result or clearly marked model | |
| Fictional model | Read an invented diagram without claiming a trial | |
| Change one thing | Compare object/orientation/passage conditions | |
| Explain and hand over | Source-bounded communication and next step |
Before each real try: an adult approves a flat, accessible, stable tabletop, two firmly fixed broad boundary strips, and a large smooth-edged card. Check the actual source, date, passage width, object dimensions/material, start/orientation, who moves it and whether touch is welcome. Do not force, flick or launch anything. If this is not available, mark REAL OBSERVATION NOT AVAILABLE and use the fictional model only to practise reasoning about a diagram. A paper drawing cannot establish that an object moved. No child photo, voice, personal story, upload or household purchase is needed.
Exact ACARA v9/QCAA crosswalk, source and rights ledger, desk QA and self-verifier/hash manifest make the claim boundary inspectable. National alignment is proposed and partial; local curriculum, safety, accessibility and classroom review remain due.
