Complete source
Ordinary fictional town-display record, not real local soil data. The same described spoon size, 20 mL water addition, filter setup and 2-minute collection window were used for samples labelled R and S. Collected-water entries in mL are R: 6, 8, 7; S: 12, 10, 11. Six separate trials are shown. The notebook does not record plant growth, drinking-water quality, organism counts or long-term field conditions. The display reader asks how much was collected in each recorded trial, not which soil is always best. The adult can use the supplied record without conducting this physical procedure.

Evidence
Faithful complete table, graph subset/unit/scale and a source-limited pattern. Supplied-data organisation can support I04; it does not establish conduct or real instrument use.
Moves
- Invite, 3 minutes: offer a notebook repair or a gallery-column job. Say, “Let's make the record useful to someone else.”
- Read, 6 minutes: read every trial and matched condition. Explain collected water as the measured output named in this record. It does not equal everything water does in soil.
- Model, 5 minutes: organise all six entries in Sample, Trial, Collected water/mL columns. Model a graph for Trial1 only with zero baseline, equal 2 mL intervals and columns at 6 and 12; label the selection.
- Try together, 6 minutes: read Trial2 and compare with Trial1. Notice that selecting a trial changes particular values without altering the complete table. Ask what missing evidence would address plants or field soil.
- Make, 12–15 minutes: choose a route. Keep all six table records available and identify any graph subset clearly. A paper token column is a model of supplied quantities, not a conducted soil experiment.
- Return, 5 minutes: ask the reader to trace one column back to its sample/trial/number. If no reader participates, record a self-check rather than inventing peer agreement.
Next teaching
For a missing or wrong unit, read complete C13: sample A/trial1 collected8 mL and sample B/trial1 collected12 mL, with no centimetres supplied. Help the child repair Length/cm to Collected water/mL before making a paper graph. For “best soil” or tomato growth from collected-water entries, read the complete C14 P4/Q9 mL garden record and its missing-growth question. Offer actual safe paper graph construction and a source-bound explanation; do not relabel these water entries as parcel lengths.
Ordinary staff model
Possible ordinary account: “These six supplied collected-water records put R at 6–8 mL and S at 10–12 mL. The R entries are lower in this setup. This is not a plant-growth or drinking-water result.” A one-trial column graph must label the selected trial rather than silently pretending to represent an average.
Question
What can a small table and graph show without promising too much?
Routes
Complete instruction
Make the complete six-row table from the supplied record. Circle or mark the trial you want a reader to inspect. Add an explanation of what was collected and one question the notebook cannot answer. Use raised lines/large labels or helper scribing without dropping sample or unit.

Notebook rescue
Complete instruction
Build two columns for one named trial using oversized paper units representing 2 mL each, or draw a scale from zero. Label both sample names and the chosen trial. Discuss the all-six table afterwards so the selected pair is not mistaken for the whole study. Keep uncertain interpretations open.

Column studio
Complete instruction
Choose the Desk's explicitly supplied ordinary town record drawer, not a held source. Inspect all six unchanged entries, then consciously select a Trial1/2/3 view. Add your own explanation in the blank fields. The display changes which record is shown; it does not generate soil outcomes or tell you what to write.
