Day 38 · Follow a public water-supply clueYear 4 Science · T1 W7–8 · Lessons / Day 38

Start: “Where does this town's supply story begin?”

Purpose: Use a dated public source for a bounded local example and separate natural cycle from human water supply.

Prepare

Read today's complete model and two contexts before the session. Paper, a pencil and the full written picture words are sufficient. Optional actual water work follows ordinary preparation; the teacher chooses suitable familiar materials/instruments. Use today's three routes without assigning a fixed learning-style label.

Run the session

1. Reconnect: a tap delivers water; it does not identify the original source by itself.

2. Model: read F5 with its Council URL and 9 October 2026 review date. Build Barrage → Glenmore Water Treatment Plant → Rockhampton/Gracemere supply. This is the stated public system example, not a verified household connection.

3. Try: children label a human supply route beside a natural-cycle model. Treatment is a human process; the source here does not teach detailed treatment chemistry or verify current water quality.

4. Compare: replace the named places with a made-up town. Ask which facts would need a new publisher/source before calling the result real. A review date is not a page publication date.

5. Make: a visitor card states one useful named fact, the responsible publisher/date reviewed and one limit. Adult source help carries the full links/rights and local replacement procedure.

6. Exit: “This source tells us __. It does not tell us __.” No addresses, household survey or outdoor trip is requested.

Three ways in

Public-route mapper

Arrange the three named source cards with supply-route arrows; compare to the process-labelled natural model.

Worked ordinary reasoning: The Council names the Barrage, Glenmore plant and Rockhampton/Gracemere service; these supply arrows are not evaporation or precipitation.

Visitor caption

Write, dictate, sign or type a two-line public information caption and a limit; a helper can read the Council fact aloud.

Worked ordinary reasoning: A Council example names Glenmore's Barrage source. It does not prove my home's current connection or water quality.

Source checker

Use a complete adult-approved broad public source card from another locality, or the supplied F5 card; separate stated/reviewed/unknown dates.

Worked ordinary reasoning: I name the publisher and reviewed date; if no publication date is stated I keep “not stated”.

Look and choose the next teaching

Named bounded fact, sensible source/date distinction and no unsupported household/Queensland-wide claim.

If supply and natural arrows are mixed, rebuild one of each with their exact named jobs.
