# Separate teacher keys · fresh Days 75 and 80

Use after [first independent response](ASSESSMENT.md) is saved. The key supports formative next teaching, not numerical grading, diagnosis, classroom pilot claims or a full year judgment. There is **no fixed real-material response**: any actual sound/felt/not-discernible result depends on a verified local object, support, very gentle action, observer/access and date. An attributed **ADULT REPORT** is not the child's direct sense. A drawing or printed sound word is not an actual material observation.

## Day 75 · Case M

- **Strong bounded paper response:** the author drew a silver six-sided PAD outline and FINGER arrow, then wrote “SOFT SOUND EVERY TIME”. That is the author's paper claim, not a heard school result. Colour and PAD label do not verify a real material. No actual source/date/support/action/observer is supplied; “every time” is an unsupported universal claim.
- **Next safe question:** “For this one approved broad verified material on this stable support, what, if anything, can a consenting observer notice after a warned single very gentle adult action?” Record a genuine before prediction, local date, action, direct or attributed access and exact response. Quiet paper-only remains valid source reasoning.
- **Do not award:** any actual loud/soft outcome from M; AC9SFI02 investigation because a child read or touched paper; inference that all pads behave identically; a child's willingness to hear/touch as ability.
- **Next teaching move:** if paper/real is merged, revisit an arrow versus a dated actual record; if “always” is accepted, ask which different supports/materials have not been tested; if strong, plan one optional locally approved action.

## Day 80 · Case N

- **Strong bounded paper response:** A is drawn as a broad arch alone, B as the same arch with diagonal overlay. A layer is added in the drawing, but actual material, support, method and response are unknown. The printed “ALWAYS SILENT” sentence is an untested claim; a drawn overlay cannot prove silence, soundproofing or composition of a real object.
- **Next safe question:** verify one broad real card and a safe non-latex broad layer, same stable support/action point, permission/comfort, source/date, genuine prior prediction; if welcome, at most one warned very gentle tap for each condition with separate comfort check. Record exact actual observations or NOT DISCERNIBLE/NOT TESTED, plus other differences such as added thickness/mass. Do not claim a pure material cause from a single pair.
- **Do not award:** a fixed sound result, material verification from stripes, AC9SFI04 prediction-versus-observation without genuine before and after records, or a capacity/design/musical-performance result as Science material evidence.
- **Next teaching move:** if child names only a stripe, ask which real parts would need verification; if child assumes silence, practise claim versus evidence; if source discipline is clear, consider an approved genuine comparison or a new safe question.

**Interpretation:** A paper source can show question and source reasoning. AC9SFU03 actual composition/property evidence needs verified real material and actual observable response; the response is setup-bound. AC9SFI02 requires a safe genuine investigation; AC9SFI04 requires actual prior prediction and later observed result. If no optional action occurred, write **REAL OBSERVATION NOT AVAILABLE**, not learner inability or lack of progress. One held response cannot certify term/year learning.
