Title
Lunchbox making trail
Complete source
Fictional lunchbox display: a clean foil sheet package says aluminium. The sheet is folded, and no maker or mine location is listed. F1 links bauxite to the industrial aluminium-making route. No food-contact, heat or leak trial is supplied.
Invitation
Make a tiny resource-to-object trail for a lunchbox-label reader. Choose paper drawing, spoken/AAC or a literal Desk note.
Ordinary possible response
The package names aluminium; F1 links its production with bauxite. I see a fold in this sheet.
Boundary
A fold is not a food-safety or local-mine result.
Next try
Try a different useful job for the same named metal, keeping its actual evidence boundary.

Title
Costume star clue
Complete source
Fictional costume studio: a shiny star drawing is labelled made-paper model; a separate foil scrap has an aluminium package label. The star has no material certificate.
Invitation
Choose which statement belongs to which object and put a source label next to it.
Ordinary possible response
The model star is paper in the source; the labelled scrap is aluminium. Shine alone does not identify either.
Boundary
Do not identify material from colour or shine; do not infer real wearability.
Next try
Offer a dull-looking supplied aluminium drawing and ask what a label can establish that appearance cannot.

Title
Repair-museum sequence
Complete source
Fictional museum cards list bauxite ore, alumina, aluminium metal and rolled foil; order and process are supplied from F1. A fifth manufacturer-space is empty.
Invitation
Arrange the four cards and explain one name change to a visitor.
Ordinary possible response
The ore and foil have different names because the source describes processing and making stages.
Boundary
The display does not reveal a manufacturer or demonstrate refining.
Next try
Choose one question for the empty manufacturer-space without inventing a supplier.

Title
Rock components postcard
Complete source
Fictional postcard has a rock outline filled with big pale/dark paper blocks. Historical U02 E3 describes minerals as rock components; no component names are given here.
Invitation
Write or direct a components caption and a question about the unnamed blocks.
Ordinary possible response
The paper blocks model components; this picture cannot name their minerals.
Boundary
A paper block is not a real grain or identified mineral.
Next try
Compare a second differently coloured model while keeping both identities open.

Title
Folded desk sign
Complete source
Fictional shop sign plan records a labelled foil strip bent into a curve. It needs a curved label, and the source records bending into that drawn curve only.
Invitation
Link the recorded property to the chosen sign job in one explanation.
Ordinary possible response
The supplied strip bends into the planned curve, which matters for this curved label.
Boundary
No strength, outdoor life or food-use evidence is supplied.
Next try
Choose a new need that bending does not answer, such as standing in wind, and leave a test question.
Id
C06
Title
Lamp-wire diagram
Complete source
Fictional reading-corner drawing labels a coil copper and shows no powered circuit. F2 links copper's electrical conduction to wiring.
Invitation
Give a source-supported wiring explanation without pretending the drawing is a test.
Ordinary possible response
F2 describes copper as a good electrical conductor used for wiring; this diagram did not measure it.
Boundary
No mains, disassembly, battery experiment or observed conductivity is invited.
Next try
Explain the difference between a provider property and a feature you can actually see in the diagram.

Title
Pot label with more than plants
Complete source
Fictional balcony display sketch shows leaf bits and spaces in sealed soil material. F3 describes soil roles for organisms and water as well as plants.
Invitation
Choose two roles for a visitor's fold-out card and one specimen question.
Ordinary possible response
Soils can provide habitat and regulate water; the source supports the general roles.
Boundary
The drawing gives no organism count, local water result or growth result.
Next try
Ask what observation would help tell who lives in one actual pot, without opening it now.
Id
C08
Title
Empty habitat window
Complete source
Fictional nature-table card shows a sealed soil view with no visible worm. The accompanying F3 role card describes soil habitats.
Invitation
Make a careful caption for the empty-looking view.
Ordinary possible response
No worm is visible in this supplied view; that does not show that soil cannot be habitat.
Boundary
Absence in a small view is not a survey of all organisms.
Next try
Offer a separate fictional close-up with a labelled organism and compare only the recorded views.
Id
C09
Title
Rain-role notice
Complete source
Fictional display writer says soil can regulate water, citing F3, and wants a water-role note. No filtered-water safety record is present.
Invitation
Make a useful role note with a clear open question.
Ordinary possible response
Soil water roles matter, but this record does not show our water is safe to drink.
Boundary
No tasting, filtration-for-drinking activity or pot-specific claim.
Next try
Choose what a suitable adult expert source would need to report for a different water question.

Title
Graphite industrial clue
Complete source
A fictional electronics exhibition uses a source-labelled text card F5. The 2017 USGS publication describes graphite properties relevant to electronics and lubricants. No mine/rank or current-market data is adopted.
Invitation
Give one source-described use relationship for the exhibition reader.
Ordinary possible response
F5 links graphite properties with industrial uses; the exhibit is a text explanation, not a working device.
Boundary
No battery disassembly, powder handling or pencil composition claim comes from this card.
Next try
Ask for a more specific safely readable product-source label instead of guessing every device contains natural graphite.

Title
Interval walk on paper
Complete source
Fictional tape diagram has zero, 1, 2, 3, 4 cm marks and a paper label spanning zero to four. Five tick marks bound four intervals.
Invitation
Use large paper steps or pointing to show the measured length.
Ordinary possible response
The span is 4 cm: I count the intervals from zero, not all five marks.
Boundary
Diagram reading is not measurement of an actual rock or scaled instrument operation.
Next try
Measure a different actual paper strip with a familiar ruler if supervised and wanted; keep its own record.
Id
C12
Title
Drawn parcel bases
Complete source
Fictional parcel drawings P and Q have printed base labels 3 cm and 5 cm. Print-size changes do not change the supplied recorded labels.
Invitation
Compare the supplied drawn bases and label the evidence source.
Ordinary possible response
Q is 2 cm longer than P in this supplied record; I have not measured actual parcels.
Boundary
No weight, strength or actual object dimension follows.
Next try
Offer actual large paper shapes and write a prediction before obtaining their own ruler readings.

Title
Repair table units
Complete source
Fictional display notebook lists sample A, trial1, collected water8 mL; sample B, trial1, collected water12 mL. It supplies no centimetres.
Invitation
Repair a table that wrongly labels its last column Length/cm.
Ordinary possible response
The column is Collected water/mL because those are the quantities supplied.
Boundary
A numeric difference alone does not identify the measured quantity.
Next try
Try an unrelated parcel-length table and choose its actual quantity/unit before graphing.

Title
A question bigger than its data
Complete source
Complete original fictional garden card, not local soil data. In one supplied trial, samples P and Q use the same described spoon size, each receives20 mL water, and the same filter setup and2-minute collection window are used. The labelled collected-water entries are P4 mL and Q9 mL. A visitor asks which soil grows the tallest tomatoes. No plant-growth, soil-quality, organism-count or drinking-water entries exist; no real child conducted this trial.
Invitation
Give a useful response that shows both a supported comparison and missing evidence.
Ordinary possible response
In this supplied single trial, P collected4 mL and Q9 mL, so P’s recorded amount is5 mL less under the stated setup. These are collected-water outputs, not tomato heights. I cannot rank tomato growth from this record.
Boundary
Collected water is not a universal soil-quality score.
Next try
Propose a specific separate growth question and suitable longer evidence; no plant result is invented.

Title
Library signal plan
Complete source
Fictional library display code says Circle = shelf needs review and Square = review complete. The log shows Circle at10:00, future10:30 blank.
Invitation
Explain the current plan decision using the whole supplied code.
Ordinary possible response
Circle tells the reader to review this shelf under this fictional plan; later completion is unknown.
Boundary
This is an ordinary reasoning analogue, not a soil sensor or a real library event.
Next try
Choose a question for the next record that would distinguish planned from completed work.
Id

Title
Transport-board next record
Complete source
Fictional depot sign shows current red card = inspect the display label, blue = label inspected. The next row has no entry.
Invitation
Make a current decision and a next-record question.
Ordinary possible response
The red record supports the inspect-label plan; I need the later entry before saying it was inspected.
Boundary
Do not promise transport safety or identify an actual depot.
Next try
Use another invented code with an explicitly different legend and reread it before deciding.
Id

Title
Source-hidden revision
Complete source
Fictional two captions: version1 says “This rock came from here”; version2 says “The supplied drawing does not name a quarry.” Neither names an actual place.
Invitation
Choose a keep/change/open reason for a display reader.
Ordinary possible response
I prefer the bounded second caption because it does not invent a local quarry.
Boundary
No caption establishes real location or mining permission.
Next try
Add a reviewed public source date if one is actually available; otherwise keep location open.
Id
C18
Title
Silence is not a review
Complete source
Fictional show invitation has no reader response. The owner wonders whether the trail was useful.
Invitation
Write an honest feedback record and a possible invitation.
Ordinary possible response
No feedback was supplied. I could ask a willing reader what they understand about my source.
Boundary
A silent or imagined reader is not evidence of uptake, access success or agreement.
Next try
Use one actual consensual question if available, then distinguish that reply from your own design choice.

Title
Two jobs, same resource
Complete source
Fictional maker chooses a source-labelled aluminium foil backdrop or a source-labelled aluminium-can diagram; F1 names both general uses. No specific product performance is tested.
Invitation
Choose a job and explain what source and further observation would help.
Ordinary possible response
The same named metal has different uses; my chosen job needs its own evidence.
Boundary
Do not transfer a folding observation to can strength or recycling outcomes.
Next try
Make a second explanation for the other reader with a different open question.
Id
C20
Title
A trail worth keeping
Complete source
Fictional folio contains an owner-chosen soil-role card citing F3 and an empty local-observation page. It is ready for a private reader but not a completed field study.
Invitation
Give one supported feature to keep and a new question.
Ordinary possible response
I will keep the source-linked habitat role and leave local organism observations open.
Boundary
Keeping a feature is legitimate; no annual mastery or local result is claimed.
Next try
Choose one small future evidence job with adult review and a different product, such as a water-role bookmark.
