Teacher draft · ten distinct 25-minute sessions, Days 131–140. Week 27 asks how a real object may have more than one visible material and why a shared surface feature does not prove the same material. Week 28 asks what we can learn from a direct safe inspection and what requires an attributed, verified maker/source answer. The focus follows the integrated Week 27 objects alike/different and Week 28 asking someone while keeping Science evidence distinct from maths mass/length, HASS interview and English report claims. It advances past Weeks 25–26's movement-source work and does not repeat the earlier water investigation.
Start with complete original K/L/M/N sources and safe material preflight. Use the ten scripts, thirty flexible learner routes, twenty worked optional swaps, three narration-ready read-alouds and ten no-burden family choices. Keep the fresh Days 135/140 cases unseen until first independent responses, then use the separate keys. The exact national/Queensland crosswalk, source/rights ledger and four-view desk run show the evidence limits.
Quick start for a teacher: print the split-sign and three-swatch pages. Read K first and ask what is drawn. Read L's fictional maker note separately to reveal its A/B/C labels and the ribbed paper-based counterexample. For genuine Science inspection, prepare only locally approved, broad clean verified materials with no loose fibres or forced touch; record source/provenance, local date, raw visible feature, direct access versus attributed ADULT REPORT, hidden joins and any interruption. If safe known materials are unavailable, write REAL OBSERVATION NOT AVAILABLE and use the complete FICTIONAL MODEL reasoning route. A paper stripe does not identify a real material.

Status: original SubjectNest draft. Human educator, accessibility, local state/territory syllabus, materials/safety, privacy and classroom review remain pending. The read-only verifier checks completeness, seven exact pinned official rows, local links, print geometry/text and hash receipt; it does not prove classroom effectiveness. No pilot, measured gain, universal access certification, state approval or ACARA/QCAA endorsement is claimed.
