# 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.

## Day

42

## 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

### Complete instruction

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.

### Complete instruction

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.

### Complete instruction

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.
