Curriculum and evidence scope
National binding
The owned fixed prior authority selection contains all 96 Year 4 Science records: level context, strand/substrand descriptions, twelve core descriptions, all selected illustrative elaborations and the whole achievement standard. The exact 481 present raw typed XML cells include 479 nonempty and two present-empty values. Absent worksheet cells remain absent. The normalized selection is the29September 2026 source snapshot; the inherited9October 2026 acquisition reports the same 2,049,917-byte workbook body with SHA256 db446882d2c00cf7c085a03e250e2442fda6c44011fc114680c46c1dc7a822c3. The proposal author used the inherited whole selection and raw records, not a new download or independent workbook parse. NATIONAL-CHECK verifies their full internal row/cell/attribute/plain-text binding; it cannot independently reacquire source truth.
Principal work and honest limits
| Code | Work in these lessons | Evidence boundary |
|---|---|---|
| AC9S4U02 | Days 31–34 explicit sources/stores, evaporation, condensation, precipitation and sky/land/ocean models;39 explanatory use | Fresh A/B/D may show process understanding; no full-year completion claim |
| AC9S4H01 | Separate observation/data from explanation, use supplied clues and valid records | Source tasks show interpretation; actual data use must be documented |
| AC9S4H02 | Useful visitor explanation and bounded Council supply example | Match scientific explanation to a stated need, not a claim of verified supply quality |
| AC9S4I01 | Questions and cautious predictions based on supplied or actual observations | Record which basis was used; model choices do not establish observation |
| AC9S4I02 | Explicit scaffold, one change, matched conditions, safe feasible steps | Paper plan may support planning; actual conduct stays unobserved unless observed |
| AC9S4I03 | Day 36 teaches familiar scaled instrument/unit/procedure; optional supervised actual use | A paper scale/source reading is not actual formal measurement. Record actual instrument/support/action/value |
| AC9S4I04 | Water models, tables and taught simple column graph with equal labelled axis | Correct source representation differs from observing/collecting its data |
| AC9S4I05 | Compare matched records, assess fairness, ask further questions, draw limited conclusions | Fresh C samples interpretation; no inferred conduct/fairness attainment from a supplied plan alone |
| AC9S4I06 | Audience/purpose-based explanatory products, appropriate vocabulary and optional digital tool | Written/dictated/drawn alternatives remain meaningful; no mandatory recording/share/account |
| AC9S4U01 | Earlier habitat prerequisite/context only | No new principal biological coverage claimed |
| AC9S4U03 | Earlier forces/scaled-distance context only | No new principal forces coverage claimed |
| AC9S4U04 | Earlier materials/function context only | No new principal materials coverage claimed |
Illustrative elaborations offer possible approaches. They do not form a checklist requiring these ten lessons to conduct water-use surveys, reproduce First Nations knowledge, make a model of every hydrological path or cover every Year 4 topic. General capabilities and cross-curriculum links arise where genuinely used: critical source/data thinking, accessible communication and sustainability discussion. No claimed cultural translation or blanket cultural practice is authored.
Queensland
The complete current QCAA Year 4 Science alignment (1page), standard elaborations (5pages), and Years 3–4 suggested assessment conditions (3pages) were read on 9October 2026. The alignment connects the official national understanding/inquiry with the achievement standard. Standard elaborations guide on-balance folio judgment; this local 32-component bank is neither the official A–E matrix nor a full folio. Conditions and adjustments must be selected for the real class/task and actual evidence opportunities. Planning a supported observation is not evidence that it occurred. Later forms offer a similar small criterion in a different source, not proof of a statistically calibrated equivalent test.
This source edition establishes a QLD-informed sequence only. It has no verified state-by-state equivalence map for NSW/Victoria/other jurisdictions, no Years11–12 syllabus accreditation and no teacher/classroom effectiveness result. Adult local-source replacement and flexible routes are available design requirements, not proof of universal individual customisation.
