Complete source

Ordinary fictional irrigation-story board. In this imagined garden only, a recorder code says BLUE = more water than this plan needs now; GREEN = enough for this plan now; RED = less than this plan needs now. At 09:00 bed L is BLUE and bed M is RED. Tomorrow is empty. The agreed fictional plan says pause adding water at BLUE and review/add the planned amount at RED with the supervising adult. This is not a calibrated local sensor or a rule for real plant care. F4 independently describes CSIRO's Chameleon research as helping farmers interpret soil water at different depths to make decisions; its page was last updated in 2022, not a 2026 result tally.

Evidence

A particular data-to-explanation-to-need chain, with fictional versus provider evidence and future result distinct. No physical sensor or local agronomic credit from the supplied board.

Moves

• Invite, 3 minutes: choose a “help the garden-plan reader” job. No watering of a real plant is required.
• Read, 6 minutes: read the full code, two records, plan and empty tomorrow. Read the short F4 paraphrase separately, keeping its provider, country context and 2022 publication status visible.
• Model, 5 minutes: join L's supplied code to the supplied plan. Leave the tomorrow field blank and explain why following a plan is not proof of a successful result.
• Try together, 6 minutes: use M instead. Ask how the information changes the proposed action and what further record would be useful. Accept different purpose-linked questions without inventing a forecast.
• Make, 12 minutes: choose a decision-flap, quiet briefing or Desk route. Separate code, evidence, explanation, need and next question in a purposeful product.
• Return, 5 minutes: compare two explanations if real partners participate. A quoted fictional second view can be analysed, but mark it fictional; no peer-comparison claim is earned merely by reading it.

Next teaching

If action is asserted without code, offer C15's library signal record. If a forecast is invented, offer C16's transport-display next-record lesson. Later held D remains separate.

Ordinary staff model

Possible ordinary explanation: “The fictional code makes the BLUE bed's current entry a reason to pause under this plan. We still need the next entry before saying what happened later.” F4 illustrates people linking information and decisions; the imagined class board is not CSIRO's device or data.

Question

How can information help with a need while leaving the next result open?

Routes

Make a two-panel flap with today's fictional L or M code and your own explanation for the supplied plan. The second panel is “Next record still open”. Put your own question there rather than an invented tomorrow colour. Keep the complete code beside the flap.

D48-1

Garden-plan flap

Use four large headings: Code, Record, Plan, Next question. Explain or direct a helper through one bed's entries by spoken words, signing, AAC or pointing plus read-back. An adult may be the intended reader. This is a planning explanation, not irrigation advice for the actual school.

D48-2

Quiet briefing

In Desk or paper make your own evidence→explanation→need trail with the complete fictional board drawer in place. Compare Source and Reader views to check attribution and audience. A manual record selection cannot create a sensor reading or a successful crop.
