Made-up practice record. A museum display compares water lost from matching trays over the same 30-minute interval, using the same taught mL reading procedure. Start amounts, place and tray type are matched. Different display labels name trays J, K and L; the source does not specify a cause for differences. The valid supplied lost-water values are J=10 mL, K=0 mL, L=5 mL. Tray M has no recorded value. Tray N spilled, so its value is invalid for this comparison. Another group's matched record gives J=5 mL. These are invented supplied records, not measurements you made.
Q1
Prompt: Make a table or columns for J, K and L. Keep the unit.
Minimum meaningful evidence: Correctly represents J10/K0/L5 on a common labelled mL basis, including visible zero label.
Worked example: Table: J10 mL, K0 mL, L5 mL. A column graph uses a common 0/5/10 mL axis and a labelled zero for K.
Next teaching: Teach a new common-axis example before returning with later C.

Actual response / support / next appointment: ______
Q2
Prompt: Which record is zero, which is missing, and which had a spill?
Minimum meaningful evidence: Keeps K0, M missing and N invalid/spill distinct.
Worked example: K is a valid supplied zero; M is not recorded; N spilled and is invalid for the comparison.
Next teaching: Use three different written records and sort value/missing/invalid.

Q3
Prompt: Compare the two J readings. What could you check next?
Minimum meaningful evidence: Compares 10 versus 5 mL and proposes a relevant procedure/condition/instrument check without invented cause.
Worked example: The first J reading is 10 mL; the other is 5 mL. I would check matching conditions and reading procedure/instrument increments.
Next teaching: Read the two full values and model a further question that does not assert why they differ.

Actual response / support / next appointment: ______
Q4
Prompt: Can these records prove J always loses 10 mL? Explain.
Minimum meaningful evidence: Limits conclusion to these supplied records, recognising another J5 record and no universal forecast.
Worked example: No. One record gives J10, another gives J5; the source does not prove an always rule.
Next teaching: Replace “always” with “in this supplied record” using a new value pair.

Use after Day 37. Preserve the earlier response and what was subsequently taught. New complete stories have familiar taught process/representation components; do not claim all-unseen answers, matched statistical difficulty or automatic improvement. Fiction/source reasoning does not establish actual measurement or conduct.
