# Foundation / Prep Science · ten 25-minute scripts, Days 131–140

Read [complete K/L/M/N fictional sources and the adult material gate](MATERIALS.md) first. Each day totals **3 + 4 + 5 + 7 + 4 + 2 = 25 minutes**. Use [thirty flexible routes](LEARNER-CARDS.md) and [worked optional swaps](OPTIONAL-PRACTICE.md) to offer access and interest choices, not fixed “learning style” labels. The adult may use locally approved large known materials after pretest, or teach a complete FICTIONAL MODEL paper route. If no actual inspection happens, mark **REAL OBSERVATION NOT AVAILABLE**. A child may decline touch; a sourced **ADULT REPORT** stays attributed. Do not treat a drawing of ribs as a verified fabric sample. Keep the [fresh Day 135/140 cases](ASSESSMENT.md) and [separate keys](TEACHER-KEY.md) unseen until first independent responses.

## Week 27 · Day 131 — Two regions in one picture

**Goal:** describe two pictured regions without naming an unverified material. **Proposed codes:** AC9SFU03 (model only), AC9SFH01, AC9SFI03. **Prepare:** [split sign picture](split-sign.svg), exact Model K, Card 131.

1. **Source · 3 min.** Label K FICTIONAL MODEL and the class actual line REAL OBSERVATION NOT AVAILABLE.
2. **Notice · 4 min.** Read left plain-looking region, right six drawn lines and the divider. No touch/material is provided.
3. **Model · 5 min.** Say “I can see drawn lines. I cannot tell which real materials a sign would contain from this picture.”
4. **Child try · 7 min.** Card 131 routes identify both pictured regions and one unknown material fact, preserving first words.
5. **Probe · 4 min.** Ask whether two printed colours prove two materials; prompt a source-based correction if needed.
6. **Exit · 2 min.** Save PICTURE ONLY description, not a physical property result.

## Week 27 · Day 132 — What a maker's note adds

**Goal:** identify two reported components of one invented object while distinguishing appearance from material provenance. **Proposed codes:** AC9SFU03 (model reading), AC9SFH01, AC9SFI03. **Prepare:** full Model L, [three pictorial swatches](three-swatches.svg), Card 132.

1. **Label · 3 min.** L is an invented maker note; materials named in it are not a classroom inspection.
2. **Read · 4 min.** Read A plain card, B ribbed woven fabric, C ribbed corrugated paper-based card, and the A+B fictional sign.
3. **Model · 5 min.** Point to drawn regions, then to L's *words* that identify card and fabric; say “The drawing did not prove that.”
4. **Child try · 7 min.** Card 132 routes place CARD BASE / FABRIC PATCH on the invented sign from L and leave hidden join UNKNOWN.
5. **Probe · 4 min.** Ask if the same-looking rib pattern proves B and C have the same material. Child names L's different labels.
6. **Exit · 2 min.** Save source: FICTIONAL MAKER NOTE, not actual local composition.

## Week 27 · Day 133 — Look at approved real surfaces, if available

**Goal:** record one actual visible feature and separately record how material identity was verified. **Proposed codes:** AC9SFU03, AC9SFI02 (actual only), AC9SFI03. **Prepare:** locally approved known large A/B/C surfaces or L paper route, [safe source gate](safe-source-gate.svg), [blank two-source record](two-source-record.svg), Card 133.

1. **Adult gate · 3 min.** Record approval, local date, exact large samples, material provenance, safe access and stop plan; otherwise REAL OBSERVATION NOT AVAILABLE.
2. **Prior question · 4 min.** Ask “What visible surface mark can we actually notice?” No one is asked to identify by touch.
3. **Inspect/read · 5 min.** Adults present broad real sample(s) safely without pressure or forced touch, or read L as FICTIONAL MODEL; record direct access versus neutral ADULT REPORT.
4. **Child raw record · 7 min.** Card 133 routes record exact visible feature for each actual viewed sample, plus material identity source or UNKNOWN; never copy L into a local log.
5. **Probe · 4 min.** Ask whether the drawn swatch picture itself verifies the material of this real sample. Child separates depiction and verified source.
6. **Exit · 2 min.** Store actual date/feature/provenance or a model-only record.

## Week 27 · Day 134 — Sort one property and keep the counterexample

**Goal:** state one visible-feature rule, sort only viewed samples under it and retain an item whose material differs. **Proposed codes:** AC9SFU03 (actual if observed), AC9SFI03, AC9SFI05. **Prepare:** genuine Day 133 log if any or Model L, [one-property sort](one-property-sort.svg), Card 134.

1. **Source · 3 min.** Keep actual dated sample record and L MODEL in separate piles; no invented result fills a gap.
2. **Rule · 4 min.** State “visibly ribbed in this view / no visible ribs in this view”; place NOT VIEWED/UNCLEAR aside.
3. **Model · 5 min.** In L only, B and C both have reported ribs, but the maker reports fabric for B and paper-based card for C.
4. **Child try · 7 min.** Card 134 routes sort their actual viewed samples if available, or L's reported model features, and name a source-based counterexample.
5. **Probe · 4 min.** Ask whether “ribbed means fabric” still works with L's C or a genuine counterexample; record the child's revised rule.
6. **Exit · 2 min.** Save rule, raw placements, NOT VIEWED and source label; no universal claim.

## Week 27 · Day 135 — Fresh composition-and-source check

**Goal:** independently identify what a new picture can show and what verified material information it lacks. **Proposed codes:** AC9SFU03 (model reasoning), AC9SFH01, AC9SFI03. **Prepare:** unseen [teacher-held Case AD](ASSESSMENT.md), blank [two-source record](two-source-record.svg), Card 135 only after response.

1. **Preflight · 3 min.** Confirm the new case is unseen; prepare literal read-aloud, large print, AAC or broad secured tactile version.
2. **Present · 4 min.** Read the full FICTIONAL PAPER CASE once without naming the missing material source.
3. **Think · 5 min.** Offer quiet independent time and log any neutral exact reread.
4. **First independent response · 7 min.** Child names depicted parts, distinguishes appearance from material identity and asks for a safe verification source; capture exact first words/access.
5. **Bound · 4 min.** Ask what an approved real object's date, maker/provenance and direct view would add. Paper-only remains REAL OBSERVATION NOT AVAILABLE.
6. **Close · 2 min.** Consult the [separate key](TEACHER-KEY.md) only after first response; Card 135 follows later.

## Week 28 · Day 136 — Ask a material question without guessing

**Goal:** pose a neutral question that distinguishes a maker's material statement from a child's own feature observation. **Proposed codes:** AC9SFH01, AC9SFI01, AC9SFI05. **Prepare:** Model N, [ask/source/explain mat](ask-source-explain.svg), Card 136.

1. **Consent/source · 3 min.** N's maker is fictional; any real teacher-maker answer is optional, willing and locally recorded without identity.
2. **Listen · 4 min.** Read N's exact question and attributed answer, including the hidden join unknown.
3. **Model · 5 min.** Adult asks “Which part did you attach, and what is your source?” rather than “It is fabric, isn't it?”
4. **Child try · 7 min.** Card 136 routes form one neutral material/source question and attribute an answer to MODEL N or a genuinely willing maker.
5. **Probe · 4 min.** Ask if hearing a maker answer means the child directly felt a material; child separates report from own sense.
6. **Exit · 2 min.** Save the question, exact source answer or no answer; a pass needs no reason.

## Week 28 · Day 137 — Two sources may answer different parts

**Goal:** combine a direct visible-feature record and a properly attributed maker/material source without collapsing them. **Proposed codes:** AC9SFU03, AC9SFH01, AC9SFI03. **Prepare:** actual dated Day 133 source if any or L/N MODEL, [two-source record](two-source-record.svg), Card 137.

1. **Sort sources · 3 min.** Put DIRECT FEATURE, ADULT REPORT and MODEL labels where they truly belong.
2. **Read/recall · 4 min.** Retrieve one exact visible feature and one exact material label/source; a missing source stays UNKNOWN.
3. **Model · 5 min.** Say “I noticed broad ribs in this view; the maker said this sample was fabric” only if both parts are genuinely documented; for L say “in the invented note”.
4. **Child try · 7 min.** Card 137 routes make a two-part source sentence with the correct actual/model label and hidden join unknown.
5. **Probe · 4 min.** Ask whether a conflicting or uncertain maker label can be silently fixed from a picture. Child keeps it unresolved.
6. **Exit · 2 min.** Save source labels separately, not a merged fact.

## Week 28 · Day 138 — Predict, inspect, and revise carefully

**Goal:** record a true prior prediction about a visible feature, compare with an actual approved view if available and preserve mixed/unknown outcomes. **Proposed codes:** AC9SFI01, AC9SFI02 (actual only), AC9SFI04 (actual prior/result only), AC9SFU03. **Prepare:** one new approved broad safe sample or L model only, [safe source gate](safe-source-gate.svg), Card 138.

1. **Gate · 3 min.** Teacher pretests material identity, safety and access for a genuinely new large sample; otherwise REAL OBSERVATION NOT AVAILABLE.
2. **Predict · 4 min.** Child predicts “I may see broad ribs / no visible ribs” **before** any actual view, or chooses NO PREDICTION.
3. **Inspect/model · 5 min.** Reveal/inspect only an approved real sample, or use an explicitly invented L drawing; no forced contact.
4. **Record · 7 min.** Card 138 routes log prior wording/order, exact observed feature or NOT VIEWED/UNCLEAR, material source and access. A model answer is not a real result.
5. **Compare · 4 min.** Compare prediction with later genuine direct feature only when both exist; otherwise CANNOT COMPARE. Do not treat a texture guess as material proof.
6. **Exit · 2 min.** Save one cautious next question, not a success label.

## Week 28 · Day 139 — Explain a counterexample to a real listener

**Goal:** share a bounded same-feature/different-material claim with source and one unknown. **Proposed codes:** AC9SFU03 (actual only if sourced), AC9SFI03, AC9SFI05. **Prepare:** actual approved records if present or L/M MODEL, [ask/source/explain mat](ask-source-explain.svg), Card 139.

1. **Choose source/privacy · 3 min.** Use a consented private actual class record or clearly marked L/M fiction; no child photos or public upload.
2. **Read M · 4 min.** Hear the broad false rule and compare with L's card counterexample in its invented note.
3. **Adult model · 5 min.** State only “In L, both B and C are reported ribbed, but the maker reports different materials”; name MODEL.
4. **Child share · 7 min.** Card 139 routes communicate feature, material identity source, counterexample and unknown to a chosen adult/willing peer.
5. **Listener · 4 min.** Record actual response only if it occurred; otherwise **NO ACTUAL LISTENER RESPONSE**. A rehearsal line is not feedback.
6. **Exit · 2 min.** Save child-controlled explanation and source labels, not an improvement score.

## Week 28 · Day 140 — Fresh material-rule check

**Goal:** independently sort a new source-labelled paper set by one stated property, preserve a counterexample and reject an overbroad material rule. **Proposed codes:** AC9SFU03 (model reasoning), AC9SFH01, AC9SFI01, AC9SFI03, AC9SFI05. **Prepare:** unseen [teacher-held Case AE](ASSESSMENT.md), blank [sort mat](one-property-sort.svg), Card 140 only after response.

1. **Preflight · 3 min.** Keep the held source unseen; prepare exact accessible equivalent and private first-response capture.
2. **Present · 4 min.** Read all novel FICTIONAL PAPER CASE labels and the claim once, without sorting for the child.
3. **Think · 5 min.** Allow independent time; log neutral reread, not a leading cue.
4. **First independent response · 7 min.** Child states the one-property sort, names the counterexample, distinguishes maker-reported material from drawn appearance and asks a safe next question.
5. **Boundary · 4 min.** Ask what local approval/date/actual view and material provenance are needed before a real-sample claim. Paper-only stays REAL OBSERVATION NOT AVAILABLE.
6. **Close · 2 min.** Use the [separate key](TEACHER-KEY.md) after first response to plan one next teaching move.
