# Foundation / Prep Science · ten 25-minute scripts, Days 21–30

Use the [local source and safety protocol](MATERIALS.md). Each day has six steps totalling **3 + 4 + 5 + 7 + 4 + 2 = 25 minutes** and three [same-target routes](LEARNER-CARDS.md). A real living-thing or panel claim needs an approved, dated, actually accessed source. A photo is labelled PHOTO, an adult's description ADULT REPORT, and an invented drawing MODEL. With no safe real source write **REAL OBSERVATION NOT AVAILABLE**; the paper task then samples source reasoning only. The [teacher-held checks](ASSESSMENT.md) must stay unseen until the first independent response is recorded.

## Week 5 · Day 21 — What is a visible feature, and whose source is it?

**Goal:** distinguish one externally visible feature of an approved live plant from a guess and name the observation route. **Proposed codes:** AC9SFU01, AC9SFH01, AC9SFI01, AC9SFI02. **Prepare:** safe live plant A view, [living-safe poster](living-safe.svg), [feature log](feature-source.svg), Model J, Card 21.

1. **Source gate · 3 min.** Adult confirms a safe accessible view of live plant A, date and broad location. If unavailable, use Model F as MODEL ONLY and mark no real observation.
2. **Notice · 4 min.** Child looks from an approved place or hears an exact attributed adult report. Ask about an externally visible part; no touching, picking or species guess.
3. **Model · 5 min.** Teacher uses Model J to contrast “I saw”, “the adult described” and “the drawing has”, then names a real plant feature only if actually visible today. Roots under soil, age and health remain unknown.
4. **Child try · 7 min.** Child chooses Card 21 route to give one exact visible feature and ask one new safe question; adult writes source/date/access and the child's words.
5. **Check · 4 min.** Offer “This plant is happy because its leaf points up.” Child distinguishes the noticed leaf position from unsupported feeling; next evidence remains open.
6. **Exit · 2 min.** Save a feature card for later grouping, or label the model feature as drawing-only.

## Week 5 · Day 22 — Compare two live plant views without guessing

**Goal:** compare features actually available from two safe live plant sources and mark what remains unseen. **Proposed codes:** AC9SFU01, AC9SFI02, AC9SFI03. **Prepare:** distinct preflighted live plant B plus Day 21 A source/card, feature log, Card 22.

1. **Preflight · 3 min.** Confirm A/B are two distinct safe living plants in accessible approved views; log each date/broad location and any different viewing distance.
2. **Look · 4 min.** View B or hear attributed neutral description. Identify two externally visible details on B without touching or naming species by appearance.
3. **Model · 5 min.** Put Day 21 A and today's B dated cards side by side. Teacher models “I can see a broad outline on this source; I cannot tell the hidden roots.” If an earlier feature was guessed, correct the card transparently.
4. **Child try · 7 min.** Card 22 routes ask one same/different visible-feature comparison with each source cited. If A is unavailable, use actual B plus a clearly labelled photo/model and do not claim two live plant observations.
5. **Check · 4 min.** Ask whether “plant B has fewer leaves” is justified if half its view is blocked. Child marks CANNOT TELL FROM THIS VIEW or narrows to “in the part I can see”.
6. **Exit · 2 min.** Keep two source-labelled cards for Day 24; no universal plant claim.

## Week 5 · Day 23 — What can an animal source actually show?

**Goal:** name two external features from an approved safe live animal view or licensed photograph and attribute the source accurately. **Proposed codes:** AC9SFU01, AC9SFH01, AC9SFI02, AC9SFI05. **Prepare:** safe live distance/window view if genuinely available; otherwise teacher-selected rights-cleared photograph with creator/licence/source; feature log, Card 23.

1. **Safety/source · 3 min.** Confirm view without chase, feed, approach or touch. If using photo, name PHOTO and its source. If neither exists, use fictional Model F2 for marks-only practice.
2. **View · 4 min.** Allow child to access the live animal or photo, or hear an exact attributed adult description. Record actual date and source type; don't infer species, sex, diet or feelings.
3. **Model · 5 min.** Teacher says “The source shows [exact visible feature]” only if it does. Contrast F2's oval/triangle marks: that drawing does not establish a real animal or actual body part.
4. **Child try · 7 min.** Card 23 asks two source-bounded features and one thing not shown. Adult scribes and labels LIVE / PHOTO / ADULT REPORT / MODEL.
5. **Check · 4 min.** Offer “This animal must sleep in a tree because its outline has a pointed part.” Child identifies behaviour/home as unknown from the observed appearance.
6. **Exit · 2 min.** Save the source card only with accurate provenance; leave a real-animal view open for later if absent.

## Week 5 · Day 24 — Can a visible rule sort our sources?

**Goal:** group dated feature cards using a stated visible rule, change the rule and preserve uncertainty. **Proposed codes:** AC9SFU01, AC9SFI03, AC9SFI05. **Prepare:** Day 21–23 actual-source cards when available, [group-rule mat](group-rule.svg), fictional Model G, Card 24.

1. **Evidence gate · 3 min.** Separate live plant, animal photo/live, adult report and MODEL cards. Do not treat Model G as local living-thing evidence.
2. **Read · 4 min.** Review exact visible features for two plants and animal source if present. Put blocked/unseen feature cards in CANNOT TELL.
3. **Model · 5 min.** Sort fictional Model G by “has broad oval mark”, then change to “has long line”; explain that the drawings did not change, only the rule did. Do not call them species.
4. **Child try · 7 min.** Card 24 asks a child-chosen visible rule for actual source cards (or model-mark cards if real set incomplete), places each with a source reason, then changes one rule. Adult records placements and unknowns.
5. **Check · 4 min.** Offer “this one belongs here because I like it”. Child identifies preference and chooses a visible feature if aiming for Science grouping; preference itself is welcome but separately labelled.
6. **Exit · 2 min.** Child explains to teacher privately or consenting listener what changed in the sort, with actual response recorded.

## Week 5 · Day 25 — Fresh living-feature source check

**Goal:** independently identify source type, an externally shown feature, an evidence-based group rule and an unknown. **Proposed codes:** AC9SFU01, AC9SFI01, AC9SFI02, AC9SFI03. **Prepare:** unseen [Day 25 held sources](ASSESSMENT.md), blank feature/group mats, Card 25 only after check.

1. **Welcome · 3 min.** Explain the check chooses the next lesson. Offer safe live/photo/adult-report/model route or pass; no forced outdoor visit.
2. **Retrieve · 4 min.** Revisit Model G's known rule-change only, without showing held features.
3. **Fresh sources · 5 min.** Present the new approved plant and live animal/rights-cleared photo if available, or the distinct invented paper pair. Log date, source and access, not a guessed species.
4. **First independent response · 7 min.** Child names exactly what each source shows, asks a safe next question, offers a visible grouping rule and marks one unknown. Save first response and prompt before feedback.
5. **Bound · 4 min.** Child says whether evidence is live view, photo, adult report or drawing; paper-only path is REAL OBSERVATION NOT AVAILABLE for local living features.
6. **Close · 2 min.** Use separate [key](TEACHER-KEY.md) for next teaching; then release Day 25 practice.

## Week 6 · Day 26 — What property would help a privacy screen?

**Goal:** ask whether a specific approved layer lets a large symbol remain visible under stated conditions and predict before testing. **Proposed codes:** AC9SFU03, AC9SFI01, AC9SFI02. **Prepare:** large filled-circle card, one adult-preflighted broad rigid panel, stable desk, [layer-test mat](layer-test.svg), Model H, Card 26.

1. **Safety/source · 3 min.** Check panel edges, verified material or UNKNOWN, same room light, distance and no face covering. No bright torch or Sun viewing.
2. **Purpose · 4 min.** Explain a fictional classroom choice: should a sign be visible through a cover, or hidden for a guessing game? Both are purposes; no child privacy disclosure is requested.
3. **Model · 5 min.** Read Model H1/H2: drawn circles and panel words do not prove real see-through properties. Teacher asks a testable question for the actual approved panel.
4. **Child try · 7 min.** Child uses Card 26 to name exact source/material if verified, pose a visibility question and predict visible/not visible/unsure before an adult-held actual panel trial. Adult records the actual view or NOT TESTED.
5. **Compare · 4 min.** Compare prediction with actual result only if the safe trial occurred; record vision access or ADULT REPORT without upgrading one to the other.
6. **Exit · 2 min.** Name one condition such as distance or lighting that a next comparison should keep the same.

## Week 6 · Day 27 — Test one layer, record a specific result

**Goal:** investigate visibility through one approved material sample and separate observable result from material label. **Proposed codes:** AC9SFU03, AC9SFI02, AC9SFI03, AC9SFI04. **Prepare:** preflighted large filled-circle card, panel A, marked stable desk, layer-test mat, Card 27.

1. **Preflight · 3 min.** Adult verifies panel A's material source or UNKNOWN and positions symbol/panel/observer safely; log local date and conditions.
2. **Predict · 4 min.** Child predicts whether the filled circle will be visible through this exact panel; record before placing it.
3. **Model · 5 min.** Teacher leaves actual-result field blank while reading invented H3 “no symbol record”; H3 is missing data, not proof the layer hid the symbol.
4. **Child try · 7 min.** Adult places panel A at marked position for a safe viewing trial; child reports direct view, or hears neutral ADULT REPORT; adult logs visible / not visible / cannot tell and any glare/position change. No trial means NOT TESTED.
5. **Check · 4 min.** Child compares prediction/result if actual, then repairs “all panels of this material do this” to “this panel here today under these conditions”.
6. **Exit · 2 min.** Save source/date/result for a second sample rather than claiming a material law.

## Week 6 · Day 28 — Compare two layers and a possible composite

**Goal:** compare two actual safe panel views where possible and distinguish a composite layer arrangement from a single material. **Proposed codes:** AC9SFU03, AC9SFI01, AC9SFI02, AC9SFI03. **Prepare:** panel A record, distinct approved panel B with verified material or UNKNOWN, same card/desk/light/distance, Card 28.

1. **Match gate · 3 min.** Check both broad intact panels and material labels, same symbol and marked positions. Note colour, thickness, surface or light differences; do not isolate material cause if they vary.
2. **Predict · 4 min.** Child predicts view through B and, if safe, through A+B together; a prediction is not a result.
3. **Model · 5 min.** Show Model H's drawn CLEAR/COVER labels as invented. Explain two panels together form a layered object with parts; the drawing cannot establish its actual property.
4. **Child try · 7 min.** Adult tests B, then A+B if locally safe, with same filled-circle card and setup. Card 28 records exact direct view or attributed report for each; omit composite if glare/access makes it invalid.
5. **Compare · 4 min.** Child names verified material parts and actual observed visibility in these tries, or UNKNOWN/NOT TESTED. Explain other differences that limit a causal claim.
6. **Exit · 2 min.** Save which actual panel could serve a chosen visible/hidden purpose; no “best material for everything”.

## Week 6 · Day 29 — Choose a material for a stated job

**Goal:** share a source-bounded material choice for a visible or hidden symbol and one limitation. **Proposed codes:** AC9SFU03, AC9SFH01, AC9SFI03, AC9SFI05. **Prepare:** dated Day 27/28 actual records if any, [science-claim page](science-claim.svg), Card 29.

1. **Source gate · 3 min.** Choose an actual tested panel log or label MODEL ONLY; do not fill result from the fictional H cards.
2. **Job · 4 min.** Child chooses fictional public sign cover (symbol should be seen) or guessing-game screen (symbol should be hidden); no private sign or personal story needed.
3. **Model · 5 min.** Teacher makes a fictional-model report: “H1 draws a circle, but I cannot claim that our rigid panel lets light through.” State missing actual source.
4. **Child try · 7 min.** Card 29 routes invite source/date, verified material parts or UNKNOWN, actual view/NOT TESTED, choice for the chosen job, and an unknown. An actual listener may be teacher privately.
5. **Response · 4 min.** If a real listener asks something, record their actual words and child's answer. Otherwise write NO ACTUAL LISTENER RESPONSE. Change a claim only in response to evidence that actually exists.
6. **Exit · 2 min.** Ask what one condition to keep constant in a future test; no universal property claim.

## Week 6 · Day 30 — Fresh material property check

**Goal:** independently predict, source, compare and bound two new panel records for a stated purpose. **Proposed codes:** AC9SFU03, AC9SFI01, AC9SFI02, AC9SFI03, AC9SFI04. **Prepare:** unseen [Day 30 held check](ASSESSMENT.md), blank layer-test mat, Card 30 only after check.

1. **Welcome · 3 min.** Explain this formative check; offer direct/attributed report/model route and pass, with no unexpected touch.
2. **Retrieve · 4 min.** Revisit known H3's missing-data distinction only, without previewing held symbol or panels.
3. **Fresh source · 5 min.** Introduce new approved safe panels and symbol under fixed conditions, or the separate new invented two-record paper case. Record source/date/access.
4. **First independent response · 7 min.** Child predicts before any real try, records each actual result or reads model marks, chooses a panel for stated visible/hidden job and names a limit. Save first words/prompt before feedback.
5. **Compare · 4 min.** Prediction vs result only for actual trials; paper case remains NOT TESTED for local material evidence. Ask which condition was held the same or missing.
6. **Close · 2 min.** Use separate key to decide next lesson. One check does not certify the whole Foundation Science year.
