These direct primary pages were read for the narrow meanings below on 9 October 2026. Our explanations and diagrams are original SubjectNest work. Provider links are references, not a grant to copy their media or proof of local visibility.
- Moon phases: Moonlight is reflected sunlight; the visible lit part changes, with a cycle of about a month. The Moon can be visible in daytime. A sparse fictional strip is not an exact cycle measurement or Australian orientation chart.
- Earth facts: turning/day and orbit/about-year are different motions. These paper jobs do not measure those durations. Exact sidereal/calendrical figures and simplified leap rules are not taught here.
- Reference systems: Earth rotation changes the ground view; a reference has a particular purpose. This bank does not teach telescope coordinates or a real constellation path.
- ARPANSA Sun/eclipses: direct Sun viewing and optical aids can damage eyes. No Sun-viewing or eclipse experiment belongs to these lessons.
Make it relevant locally
Choose a real question, then ask a grown-up to review the current source and local context. Use exact source/title/version/update/check dates, timezone, reference, units, identity and limits. A prediction is not a sighting; a missing record is not proof nobody tried. Keep child/private location data out of generic teaching examples. Any wanted actual viewing is a separate adult decision; the complete indoor notes remain available.
