# Twenty worked domain swaps · two per day

These original short cases can extend or replace context after the main lesson. All named situations below are **fictional model practice** unless an adult obtains a school-approved real dated source and logs what actually happened. The worked answer models a bounded claim; it is not supplied local data. No family purchases, personal disclosures, animal handling or fixed learning-style assignment.

## Day 21

1. **Community garden sign:** A drawing shows three long lines beside a plant icon. **Worked:** say “the drawing has three lines”; do not report three stems on a local plant without a live source.
2. **Library nature shelf:** Someone says “the leaf must be soft because it looks pale.” **Worked:** colour alone does not establish feel; use a locally safe permitted sense route or leave texture unknown.

## Day 22

1. **Window box:** Plant A's actual dated view shows two broad leaf outlines; B is blocked by a curtain. **Worked:** compare A only; do not count or classify unseen B leaves.
2. **Picture-book pair:** Two invented plant drawings show different line lengths. **Worked:** the drawings differ in shown line length; that does not establish a difference between actual live plants.

## Day 23

1. **Park poster:** A licensed photograph shows one visible wing outline. **Worked:** label PHOTO and say it shows the outline; do not claim the child saw a live bird or knows its diet.
2. **Night story:** An invented creature picture has three pointed marks. **Worked:** describe the marks only; no real species or behaviour has been observed.

## Day 24

1. **Museum drawing tray:** Three invented cards can sort by “has an oval” then “has a long line.” **Worked:** different rules move cards while marks stay unchanged; this is model grouping only.
2. **Safe view notebook:** Two dated plant feature cards show an actually visible long stem in one and no stem visible in the other's view. **Worked:** place second in CANNOT TELL, not “has no stem”, unless source supports absence.

## Day 25

1. **Garden map:** A child draws one branch line and asks whether another safe live plant has a branch. **Worked:** good next question; the drawn line is not evidence about that other plant.
2. **Animal puzzle:** A toy has four legs and a tail. **Worked:** a toy is not a live animal source; it can teach words but cannot supply real external-feature observation.

## Day 26

1. **Theatre sign:** A fictional black circle should be seen behind a cover. **Worked:** choose a testable visibility question for a locally approved actual panel; the fictional scene gives no result.
2. **Guessing game:** A fictional symbol should be hidden from view. **Worked:** the job changes the useful choice, but test the exact real panel before claiming it hides the symbol.

## Day 27

1. **Art folder:** An adult reports seeing the filled circle through an approved panel while the child hears the report. **Worked:** write ADULT REPORT with exact source/date/conditions; do not relabel direct sight.
2. **Craft label:** Model H3 has no symbol record. **Worked:** “not recorded” is different from “could not be seen”; an actual trial is still needed.

## Day 28

1. **Stage screen:** Two approved real panels differ in material *and* colour. **Worked:** record actual views if tested, but do not say material alone caused a difference.
2. **Shop display model:** A drawing puts CLEAR over COVER and prints no symbol. **Worked:** it is a model of two layers; cannot prove what any classroom composite permits us to see.

## Day 29

1. **Reading corner:** A dated approved panel test showed the printed symbol visible under stated conditions. **Worked:** that exact panel is a candidate for a visible-sign job; record the actual log and don't generalise to all panels.
2. **Paper mystery:** Only invented H2 is available. **Worked:** it can inspire a hiding-screen design question, but mark ACTUAL RESULT NOT TESTED and make no local material recommendation.

## Day 30

1. **Bus timetable cover:** A clear-looking drawing has no verified actual panel. **Worked:** a drawing cannot verify material or visibility; source and safe trial remain needed.
2. **Art-box divider:** Adult selects two broad panels but one must be held closer to the card. **Worked:** note the changed distance, compare exact observed outcomes only and avoid assigning cause to material alone.
