Twenty worked optional swaps · varied contexts, cautious…Foundation Science · T2 W15–16 · Optional Practice

All examples are original fictional diagrams, claims or future plans. They are not local observations, material verification or held check cases. A real response would need a separate safe approved date/source/action/access record. No optional example asks a child to produce a sound, handle unknown material or complete home testing.

Day 71

1. Theatre cue sketch: A paper square and arrow are drawn beside a stage. Worked report: “The arrow proposes an action; it supplies no actual sound or material response.”
2. Library sign icon: A printed hand points toward a broad board. Worked report: “The icon gives direction only; I would ask what safe actual source could answer a material question.”

Day 72

1. Craft-board plan: An adult identifies an approved broad board and stable desk. Worked report: “Before any optional gentle action I would predict a possible response and record exact material/support/date.”
2. Garden-label sketch: A blue rectangle is labelled PLASTIC on paper. Worked report: “Colour and label do not verify a real material; paper result is NOT TESTED.”

Day 73

1. Quiet notice plan: A safe adult optional touch is cancelled for comfort. Worked report: “Write NOT TESTED; a cancelled action has no actual response.”
2. Display-card plan: If an approved broad card receives one gentle adult tap, observer notes nothing discernible. Worked report: “Record the exact actual local source/observer/conditions only if this really occurs; do not infer no physical effect.”

Day 74

1. Museum label claim: A label says “this board is always loud” without a source. Worked report: “One label cannot establish every setup; ask for exact actual action/support/observer.”
2. Parcel-pad note: A fictional writer says a pad made a soft noise but names no material. Worked report: “Material and comparison conditions are UNKNOWN; do not rank card versus pad.”

Day 75

1. Festival poster icon: A broad sheet outline has TAP written above it. Worked report: “TAP is a paper word, not a classroom sound; an optional safe observation is still needed.”
2. Boat-plan sketch: A finger arrow points to a cardboard-looking drawing. Worked report: “The drawing suggests a question; its appearance does not verify actual cardboard.”

Day 76

1. Book-cover plan: One drawing has a broad cover plus fabric-looking strip. Worked report: “It depicts two labelled parts; a real cover's material and response remain unverified.”
2. Exhibition-panel plan: An actual broad approved panel might have a removable broad layer. Worked report: “Verify each real part and record UNKNOWN when material identity is not established.”

Day 77

1. Art-card comparison plan: Same approved card is pictured alone and with one large safe cloth layer. Worked report: “A/B differs in layer; do not claim sound difference until gentle actual actions happen.”
2. Notice-board pair: Two different boards are compared, one with a layer. Worked report: “Both board and layer changed; any result could not isolate the added layer.”

Day 78

1. Two imagined classroom notes: A story claims one observer heard a faint response and another could not tell. Worked report: “These are fictional claims; only preserve them as actual observations if genuine dated school records exist, then check conditions before comparing.”
2. Paper rhythm score: Two marks labelled TAP/PAT repeat. Worked report: “A repeated Arts score is not repeated Science material evidence.”

Day 79

1. Shop-display drawing: A poster claims a layered sign is soundproof. Worked report: “The drawing cannot prove soundproofing; say only what is drawn and what safe actual test is missing.”
2. Private teacher explanation: An actual verified card+layer pair has one carefully recorded response each. Worked report: “Say ‘in this setup the observer reported …’, include access/date and other changed conditions.”

Day 80

1. Transport-map icon: A map shows two stacked shapes and a wavy line. Worked report: “The wavy line is a symbol, not a measured sound or verified material.”
2. Future library board plan: Teacher proposes a quiet A/B material inquiry later. Worked report: “Record a question, comfort check, before prediction and actual source later; result is NOT TESTED today.”
