Complete selected source
Made-up practice record. A pretend sculpture room has matching pans, equal starting water amounts, the same place and the same 40-minute review interval. A taught mL procedure gives supplied water-loss readings U=5 mL, V=10 mL and W=0 mL. Pan X has no recorded reading; pan Y spilled and is invalid for this comparison. A second group's matched record gives V=5 mL. No cause for differences is supplied. These are invented records, not your own instrument use or observations.
Q1
Prompt: Represent U, V and W with their unit.
Minimum meaningful evidence: Correctly represents U5/V10/W0 on a common labelled mL basis with visible zero.
Worked example: Table: U5 mL,V10 mL,W0 mL; equivalent common-axis columns are acceptable.
Next teaching: Revisit a different common-axis table-to-columns example.

Actual response / support / next appointment: ______
Q2
Prompt: Which record is zero, which is missing, and which spilled?
Minimum meaningful evidence: Keeps W0, X missing and Y invalid/spill distinct.
Worked example: W is a supplied zero; X is missing; Y spilled and is invalid for comparison.
Next teaching: Sort a new trio before any further graph task.

Actual response / support / next appointment: ______
Q3
Prompt: Compare the two V readings and give a next check.
Minimum meaningful evidence: Compares10 versus 5 mL and names a relevant procedure/condition/instrument check.
Worked example: V is 10 mL in one supplied record and 5 mL in the other; check matching conditions/reading procedure/increments.
Next teaching: Use full written values and ask a question rather than supply an invented cause.

Actual response / support / next appointment: ______
Q4
Prompt: Do the records prove V always loses 10 mL? Why?
Minimum meaningful evidence: Limits conclusion to supplied records and recognises second V5/no always rule.
Worked example: No; the second V record gives 5 mL. These records cannot establish every future outcome.
Next teaching: Practise a source-bound conclusion with a new pair.

Use on Day 40 or later, after relevant teaching and exposure review. 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.
