Day42 · A resource is not the finished thing

Complete source

Fictional repair-display notes. Four cards read: bauxite ore; alumina from refining; aluminium metal from smelting; thin aluminium foil from rolling. The cards describe an industrial route from F1; they are not a recipe for children. Another display card says minerals contribute to rocks, following the historical national U02 E3 reference. A labelled composite-rock drawing shows pale and dark components, but does not name them. A red wrapper is nearby and has no material label. The visitor wants to know why the first card and final foil card have different names.

Evidence

A purposeful distinction between source resource and manufactured product; an explicitly labelled model. Recognising a diagram alone does not prove observation of real components.

Moves

• Invite, 3 minutes: ask “Can a shop thing have a long backstory?” Let children choose a card rather than recite industrial vocabulary.
• Read, 5 minutes: read all four source-labelled stages, the rock drawing statement and the unlabelled-wrapper limit. Keep source identity F1 beside the industrial sequence.
• Model, 5 minutes: place the four making cards in their supplied order. Describe refining and smelting as industrial changes, without demonstrating heat, extraction or tasting. Separate a rock-components model from the metal-production trail.
• Try together, 6 minutes: replace the foil picture with a deliberately ordinary paper square and ask whether its presence changes the named industrial route. Return to the actual source rather than guessing from colour.
• Make, 10–15 minutes: build or direct one complete trail through a route. Label it “source-described making trail”; a blank branch marks the mine or exact manufacturer we do not know.
• Return, 4 minutes: ask what was supplied, what was made as a model, and one useful question for the display. Give vocabulary support only after recording the child's initial meaning.

Next teaching

If order dominates meaning, use C03 and ask for one source-supported name at the beginning and end. If meaning is secure, discuss an unknown material without inventing its production history.

Ordinary staff model

Possible ordinary explanation: “The source trail names several stages. Bauxite is an ore used in making aluminium; foil is a made metal product. The picture's pale and dark parts aren't enough to identify their minerals.” A drawing may model a rock's components without being a specimen or a chemical result.

Question

How can one resource be part of a longer making trail?

Routes

Use four large paper cards headed Bauxite ore, Alumina, Aluminium metal, Foil product. Arrange the source-described order and add arrows labelled industrial processing, then rolling. Write or dictate why the first and last names differ. Add a separate open branch for the manufacturer; do not draw a local mine as if known.

Stage concertina

Use oversized paper pale/dark tiles in a rock outline; do not use loose powdered minerals. Explain that this is a model of components, not an identification key. Next to it make the separate four-stage making trail. Point to one difference between showing components and showing manufacturing stages.

Components tray

In Trail Desk or on paper, enter your own resource label and explanation after reading F1 in place. Preview your literal caption. Compare it with a plain caption “Same thing all the way” supplied as an ordinary discussion card; explain what you would clarify. Keep a version only by explicit choice; no automatic rewritten caption appears.
