Teacher draft · 10 distinct 25-minute lessons, Days 91–100. Week 19 asks what a careful movement comparison can and cannot tell us. Week 20 turns a dated, source-labelled Science record into a private explanation and next question. This is a Science companion to the integrated Week 19 and Week 20 guides. The physical example here uses one large closed carton on its broad or narrow face on a shallow adult-controlled tray; it does not reuse the integrated ring and paper-surface trial. Do not run both physical tests merely to fill a timetable. Choose the approved local setup and teach the same reasoning with the paper-only route if no physical investigation is safe or available.
Start with materials and complete source texts, then daily scripts, learner cards, optional worked swaps, family bridges, and print/text/tactile aids. Keep fresh checks unseen until the first independent response; use the separate key afterwards. National/Queensland crosswalk, source and rights ledger, and honest desk review state the limits.
Non-negotiable evidence boundary
- REAL OBSERVATION NOT AVAILABLE is the result when the school has no approved, actually run, dated setup. A page model cannot show that a carton really slid, a material had a property, or a child made progress. Record actual equipment, source/date, access, prediction timestamp/order, each trial, interruptions and exact adult support. Do not retrofit a prediction after a result.
- A person can watch, listen to a neutral attributed description, use a broad secured tactile diagram, AAC/sign/pointing, or direct an adult scribe. These routes pursue the same question. ADULT REPORT is attributed information, not the child's direct sensory observation. No fixed learning-style label.
- Closed large carton only if school-approved: no staples, sharp edges, unknown fillings, small parts, elevated launches, fast objects or animal interaction. Adult controls the pretested shallow rimmed tray; children need not touch, hear or watch the test. A quiet paper route is always available and marked FICTIONAL MODEL.
- No child names, photos, family data, precise locations or private support details enter the public assets. Optional home prompts are conversation starters, not homework or a required home experiment.
Original A4 aids
Each linked vector has a one-page selectable-text PDF and a numbered exact-text/tactile construction route in MATERIALS.md. Blank fields are intentionally blank; none claims an actual run.

Status: original SubjectNest draft; adult educator, accessibility, local syllabus, equipment/safety and actual classroom review pending. The deterministic verifier checks structure, source rows, links, asset text and file hashes, not pedagogical effectiveness. No classroom pilot or child result is claimed.
