# Staff guide · The sculpture-room pans

Use only after the own attempt. These local criteria are examples of evidence, not an official grade or a unique required phrasing.

## 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.

**Partial national link:** AC9S4I04

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.

**Partial national link:** AC9S4H01

Actual response / support / next appointment: ______

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.
