Complete source

Ordinary fictional pop-up workshop. Mina makes a foldable aluminium backdrop for a puppet scene; the labelled foil bends into a curve. A separate diagram shows a copper electrical wire in a reading lamp. F2 describes copper as a good electrical conductor and links this property to wiring. F1 describes aluminium foil as thin rolled aluminium. No child is asked to handle electricity or prove conductivity. Mina's curved backdrop stands only in the supplied drawing. Its strength, heat performance and suitability for outdoor weather have not been measured.

Evidence

A specific relevant property–use relationship and a bounded source attribution; a general “metal is good” is not equivalent to that relationship.

Moves

• Invite, 3 minutes: offer puppet backdrop or lamp clue as a job choice. Ask what each maker needs; no person has to perform publicly.
• Read, 5 minutes: read the complete workshop and facts. Say aloud which property is a supplied observation and which is a provider-described property.
• Model, 5 minutes: join job, property and evidence using the backdrop account. Keep “works outdoors” on an open card. Show that a useful property link can be conditional.
• Try together, 5 minutes: choose a different job, a bendable name-card holder. Decide what the bending record might support and what strength still needs checking. This is reasoning from a record, not a strength test.
• Make, 12 minutes: follow one route. Use one job, one relevant property and one evidence boundary. Children may choose a quiet prop, a short spoken note or a caption.
• Return, 4 minutes: let a partner or adult point to the supporting record if they actually do so. Record imagined feedback as imagined, not as a successful user test.

Next teaching

For a property named without a job, use C05's quiet sign-making task. For an unsupported performance claim, use C06's model-only flag, then invite one further question.

Ordinary staff model

A possible ordinary link is “The labelled foil can be folded into the curve shown, so the supplied bending observation matters for Mina's backdrop job.” Another is “F2 links copper's conduction to electrical wiring; our drawing did not test it.” A property-to-job explanation is more useful than calling one material best for everything.

Question

Why is a property useful for a particular job?

Routes

Make a paper puppet-scene plan with a curved-backdrop sketch and a property note drawn from the supplied foil account. Include one question about whether the actual prop will stand. You may make a safe paper prop, but its observed behaviour belongs to paper, not to aluminium by transfer.

D43-1

Puppet-maker note

One person chooses a job card, another reads the complete relevant source. Join them with an explanation by voice, AAC or a two-card sentence. Swap roles only if wanted. Use a helper's quiet reading instead of electrical or noisy equipment. Retain the property/source distinction in the record.

D43-2

Job and clue duet

Use the Desk or paper twin to write your own Useful job, Recorded property, Explanation and Evidence boundary. Choose the Claim view to check whether the property actually supports the chosen job. Its display is an organising view, not a recommendation engine.
