## Primary-source factual checks

- [Bureau of Meteorology water assessments](https://www.bom.gov.au/water/waterassessments/) reports Australian water resources, variability and uses. Our catchment and neighbourhood maps are **invented schematics**, not observations of an Australian site. Do not infer water safety, local supply or access from them.
- [British Museum: Early Egypt](https://www.britishmuseum.org/collection/galleries/early-egypt) supports the narrow claim that Nile flooding helped create fertile land for ancient Egyptian farming communities. The lesson paraphrase identifies the museum as a **modern secondary source**. No museum image or text passage is copied; no claim is made about all ancient Egyptians or other ancient societies.
- [Parliamentary Education Office: separation of powers](https://peo.gov.au/understand-our-parliament/how-parliament-works/system-of-government/separation-of-powers-parliament-executive-and-judiciary) supports the simplified Parliament/executive/judiciary roles in the civics cards. The fictional school assembly is not an actual constitutional or legal process.
- [ACCC consumer rights and guarantees](https://www.accc.gov.au/consumers/buying-products-and-services/consumer-rights-and-guarantees) is the current official source learners are directed to for real consumer questions. The invented “guaranteed forever” flyers cannot establish a legal entitlement or specific remedy. No purchasing or complaint advice is given.
- [eSafety Commissioner: consent for sharing photos and videos](https://www.esafety.gov.au/young-people/consent-sharing-photos-videos) informs the no-real-photo, ask-permission, respect-no approach. The fictional voice/image requests collect no personal data.
- [CDC guidance on choosing water filters](https://www.cdc.gov/drinking-water/prevention/about-choosing-home-water-filters.html) confirms that filter functions differ and filtration alone does not establish all harmful substances are removed. The sand-water filtrate in this pack is **never for drinking**; appearance is not a safety test. The cited page is used for this narrow safety correction, not as an Australian treatment protocol.

Science’s food-web, particle and force cards are invented classroom models; filtration uses only teacher-approved clean material under school lab rules. Actual local organisms, water systems, historical artefacts and laws need their own verified sources and permissions. Historical First Nations content-description rows about continuity, culture, knowledge and heritage are **not claimed** by this pack. A future addition would need First Nations authority, cultural and intellectual property review, appropriate Country/Place permissions and provenance.

## Scope and safety holds

These are ten **optional** 12-minute blocks in each of five areas, not the full weekly subject allocation, a state/territory sequence, year-long coverage, endorsed resource or measured outcome. Science, Geography, History, Civics and Economics descriptions are official **Year 7** records; HPE, Technologies and all five Arts subjects use the official **Years 7 and 8** band. Practical making, physical participation, Arts performance/presentation, filtration and general-purpose programming are claimed only when actually observed under school conditions. A diagram, script, score, trace or paper plan is labelled accordingly. No state-specific legal advice, local ecosystem/catchment, First Nations knowledge/language, translation or classroom effectiveness is claimed. Teacher/school reviews for safeguarding, equipment, access, privacy and local curriculum remain required.
