# Foundation / Prep Science · ten 25-minute scripts, Days 111–120

Read [complete fictional D/E and local adult safety gate](MATERIALS.md) before teaching. Each day totals **3 + 4 + 5 + 7 + 4 + 2 = 25 minutes**. Choose [three same-target access routes](LEARNER-CARDS.md) flexibly, not by fixed learning style; [twenty worked swaps](OPTIONAL-PRACTICE.md) are optional. No child must touch water or discuss feelings, family events or a spill. If no approved, actually performed, dated one-drop comparison exists, write **REAL OBSERVATION NOT AVAILABLE** and keep paper D/E **FICTIONAL MODEL**. A neutral **ADULT REPORT** stays attributed. Do not infer absorption or a water destination from a dark patch. Keep [fresh Days 115/120 checks](ASSESSMENT.md) teacher-held until first independent responses; [keys](TEACHER-KEY.md) are separate.

## Week 23 · Day 111 — What could we ask before a drop?

**Goal:** pose one observable surface question and record a prediction before any genuine result. **Proposed codes:** AC9SFU03, AC9SFH01, AC9SFI01. **Prepare:** D setup paragraph only, [question mat](drop-question.svg), Card 111.


1. **Source label · 3 min.** Mark D FICTIONAL MODEL. Record whether a locally approved actual source could be offered; otherwise REAL OBSERVATION NOT AVAILABLE.
2. **Read setup · 4 min.** Read D only through the two dry surfaces and planned one-drop action, not its after entries.
3. **Model question · 5 min.** Adult asks “What visible mark might appear after the same short wait on each surface?” and models a *possible* prior prediction, not a fact.
4. **Child try · 7 min.** Card 111 routes ask/select a question and prediction before the result is shown; adult records exact words/order and model/actual plan.
5. **Check · 4 min.** Ask whether “paper absorbs it” is already observed before any drop. Child changes it to a prediction or unknown.
6. **Exit · 2 min.** Preserve question/prediction separate from later evidence.

## Week 23 · Day 112 — What must stay steady?

**Goal:** plan one surface change and steady drop method, wait and viewpoint in a safe comparison. **Proposed codes:** AC9SFU03, AC9SFI01, AC9SFI05. **Prepare:** [surface plan](surface-plan.svg), D setup, broad fixed labels, Card 112.


1. **Safety gate · 3 min.** Adult confirms or declines local approval, known large materials, catch tray and cleanup; no child handles water.
2. **Read · 4 min.** Name plain paper and plastic mat as the planned surface difference; keep drop method/wait/view the same in the plan.
3. **Model confound · 5 min.** Adult changes a paper WAIT card for one imagined surface and shows why that adds a second difference.
4. **Child try · 7 min.** Card 112 routes select same/change labels and an interruption rule for run-off or spill; no paper diagram becomes a real test.
5. **Check · 4 min.** Ask whether a large drop on one sheet and a tiny drop on the other isolates surface. Child identifies drop amount as another change.
6. **Exit · 2 min.** Save child-controlled plan and adult safety decision.

## Week 23 · Day 113 — Before, during and after are different evidence

**Goal:** sequence exact visible states and adult action without asserting an unseen mechanism. **Proposed codes:** AC9SFU03, AC9SFI02 (actual only), AC9SFI03. **Prepare:** [three-moment mat](three-moment.svg), school-approved actual setup *if genuinely available* or D, Card 113.


1. **Choose source · 3 min.** Mark ACTUAL/local date/approval/materials if the adult truly runs the event, or D MODEL with REAL OBSERVATION NOT AVAILABLE.
2. **Before · 4 min.** Record only what the actual observer can see before action, or D's “no visible wet mark” as model text.
3. **During · 5 min.** Adult places safe tiny drops under approved conditions, or reads D's imagined action; record who did it and any interruption.
4. **After · 7 min.** Following the same real wait or D's described pretend wait, Card 113 routes record exact visible mark/drop on each surface, plus source/access.
5. **Check · 4 min.** Ask “Did you see water move inside the paper?” Child says only the visible mark was recorded; destination unknown.
6. **Exit · 2 min.** Keep before/action/after separate and any spill in adult procedure, not classroom inquiry.

## Week 23 · Day 114 — Are two pairs enough for a careful claim?

**Goal:** preserve raw paired observations, classify interruptions and compare a genuinely prior prediction when available. **Proposed codes:** AC9SFU03, AC9SFI02 (actual only), AC9SFI03, AC9SFI04 (prior prediction only). **Prepare:** [paired record](paired-record.svg), approved setup if still safe or full D, Card 114.


1. **Source/date · 3 min.** Use the true local record if obtained; otherwise D MODEL. Do not “complete” missing real entries from D.
2. **Prior status · 4 min.** Retrieve a prediction only if recorded before actual results; else NO PRIOR PREDICTION.
3. **Model raw · 5 min.** Read first pair exactly, preserving surface and appearance. Explain that run-off is INTERRUPTED, not a hidden mark.
4. **Child try · 7 min.** Adult safely performs another real pair if approved and feasible, or reads D's second pair and fifth entry. Card 114 routes record raw order/validity.
5. **Check · 4 min.** Compare the exact valid appearances with prior prediction if it exists; mixed or too few actual tries gives a limited/unclear conclusion.
6. **Exit · 2 min.** Save unchanged raw source and one cautious first statement.

## Week 23 · Day 115 — Fresh fair-drop check

**Goal:** independently identify a second changed condition in a novel paper case and bound what it can show. **Proposed codes:** AC9SFU03, AC9SFI01, AC9SFI03. **Prepare:** [teacher-held Case Z](ASSESSMENT.md), blank [surface plan](surface-plan.svg), Card 115 after response.


1. **Preflight · 3 min.** Confirm case unseen; prepare exact read-aloud, large print or broad secured tactile equivalent and private first-response capture.
2. **Present · 4 min.** Read the full FICTIONAL case once without cueing the extra change.
3. **Think · 5 min.** Independent quiet time; neutral reread is logged.
4. **First independent response · 7 min.** Child names planned surface change, another changed condition, what the paper can/cannot prove and a safer actual comparison; record first words/access before feedback.
5. **Bound · 4 min.** Ask for genuine approved source/date/raw appearances needed for a real property claim. Paper-only stays REAL OBSERVATION NOT AVAILABLE.
6. **Close · 2 min.** Use [separate key](TEACHER-KEY.md) for the next teaching move; Card 115 follows later.

## Week 24 · Day 116 — What can a dark mark actually tell us?

**Goal:** name exact source-backed appearance and separate it from a mechanism guess. **Proposed codes:** AC9SFU03, AC9SFH01, AC9SFI03. **Prepare:** actual dated source if any or D, [claim/unknown](claim-unknown.svg), Card 116.


1. **Source label · 3 min.** Mark ACTUAL/date or D MODEL on the record; adult report remains attributed.
2. **Re-read · 4 min.** Read the exact appearance entries, including different plastic shapes, without “soaked” or “waterproof” claims.
3. **Model · 5 min.** Adult says of D: “This invented paper entry is a DARK PATCH. I cannot see where the water went.”
4. **Child try · 7 min.** Card 116 routes give one appearance sentence with source and one unknown; a real result may be different or unclear.
5. **Check · 4 min.** Ask whether the dark patch proves water vanished inside. Child identifies that as a possible explanation needing more evidence.
6. **Exit · 2 min.** Save bounded description, not a fixed material rule.

## Week 24 · Day 117 — Which sentence reaches beyond the record?

**Goal:** distinguish D-supported description from E's untested mechanism and universal claim. **Proposed codes:** AC9SFH01, AC9SFI03, AC9SFI05. **Prepare:** full E, [claim/unknown](claim-unknown.svg), Card 117.


1. **Label source · 3 min.** E is FICTIONAL MODEL text, not a real witness or listener.
2. **Read · 4 min.** Read both E captions fully; one repeats drawn marks, the other asserts a mechanism and every-plastic rule.
3. **Model · 5 min.** Adult underlines exact D entries that support only the first caption and says the second needs new evidence.
4. **Child try · 7 min.** Card 117 routes sort SUPPORTED HERE / NOT SHOWN HERE and restate one cautious sentence without using “always.”
5. **Check · 4 min.** Ask if two invented pairs can establish what every real paper/plastic does. Child says no and names source limit.
6. **Exit · 2 min.** Keep exact child correction; never turn E's fake caption into actual feedback.

## Week 24 · Day 118 — What safe question comes next?

**Goal:** propose a new observable question and an adult-approved source while leaving unseen mechanisms unknown. **Proposed codes:** AC9SFH01, AC9SFI01, AC9SFI05. **Prepare:** [claim/unknown](claim-unknown.svg), D/E, current local safety decision, Card 118.


1. **Safety reminder · 3 min.** A real accidental spill goes to the school-approved adult procedure, not a child test.
2. **Revisit · 4 min.** Identify one D appearance and one E leap beyond the source.
3. **Model question · 5 min.** Adult asks “After another equal short wait, what visible mark would be present?” rather than “Where did water disappear?”
4. **Child try · 7 min.** Card 118 routes choose a safe next observable question, one condition to hold steady and an adult to approve it; no home experiment.
5. **Check · 4 min.** If question requires touching an unknown wet material, child switches to a no-contact adult observation route or leaves it unanswered.
6. **Exit · 2 min.** Save next question/approval status, not an invented result.

## Week 24 · Day 119 — Explain source, evidence and uncertainty

**Goal:** privately share an honest material observation or labelled model reading and one next question. **Proposed codes:** AC9SFU03, AC9SFI03, AC9SFI05. **Prepare:** [source handover](source-handover.svg), actual consented dated record if any or D/E, Card 119.


1. **Source/privacy · 3 min.** Choose genuine class record with consent or FICTIONAL MODEL. Teacher listener is enough; no child image/location shared.
2. **Order · 4 min.** Lay SOURCE, PRIOR PREDICTION IF REAL, EXACT MARKS, CLAIM, UNKNOWN in sequence.
3. **Model · 5 min.** Adult gives D-only example: invented dark paper patch, plastic visible drops, water destination unknown, safe next check needed.
4. **Child share · 7 min.** Card 119 routes communicate exact evidence/limit by speech, AAC, sign, pointing, drawing or adult-directed scribe; record actual independence/prompt.
5. **Feedback · 4 min.** Log actual listener response only if it occurred; otherwise **NO ACTUAL LISTENER RESPONSE**. A rehearsal line is not feedback.
6. **Exit · 2 min.** Keep private handover and next safe question, not a child-growth score.

## Week 24 · Day 120 — Fresh source-and-claim check

**Goal:** independently interpret a new paper surface record, interruption and overbroad conclusion. **Proposed codes:** AC9SFU03, AC9SFH01, AC9SFI01, AC9SFI03, AC9SFI05. **Prepare:** [teacher-held Case AA](ASSESSMENT.md), blank [source handover](source-handover.svg), Card 120 after first response.


1. **Preflight · 3 min.** Ensure unseen case and exact full oral/large print/broad secured tactile equivalent; prepare private record.
2. **Present · 4 min.** Read complete FICTIONAL paper case with all raw entries and caption.
3. **Think · 5 min.** Independent time; log neutral reread, never cue the answer.
4. **First independent response · 7 min.** Child names source, valid and interrupted entries, a supported sentence, unsupported universal mechanism and a safe next actual source; record first words/access.
5. **Bound · 4 min.** Ask what approved actual materials/date/wait/raw observations are missing. If absent, REAL OBSERVATION NOT AVAILABLE.
6. **Close · 2 min.** Use [separate key](TEACHER-KEY.md). This check cannot certify a term/year or child improvement.
