All aids are original computer-created A4 teaching diagrams/blank aids, not actual experiments or learner work. PDFs are searchable but untagged. An adult can read/sign/describe the following exact source order; no print, sound, touch or new materials required. Keep usual communication supports. Optional tactile representation uses only locally suitable familiar resources, preserves the named relationships and never turns an ideal model into actual light/observation. No direction/range/posture/grasp or numerical-projection target. Fresh aids remain unanswered; teacher key is separate.
light-parts
Exact geometry/status: Original broad lamp/torch icon at left, vertical opaque card at centre, pale rectangular screen at right; no measured diagram scale or actual apparatus.
Exact visible text in XML source order: Choose a shadow idea | Source, blocker and screen ideas; not supplied apparatus or a trial. | WHERE DOES THE LIGHT START? | LIGHT SOURCE | A familiar lamp/torch. | Use only if approved. | OPAQUE BLOCKER | Stops some light paths. | An adult can position it. | RECEIVING SCREEN | Shows an available shadow. | Other light may reach it too. | S5-LIGHT-PARTS-01 · ORIGINAL MODEL / BLANK AID | SubjectNest by NeuroForgeIO Pty Ltd with Codex assistance | Created 30 September 2026 · computer-created teaching source | Purpose: name roles; choose a shadow job or light question | No actual trial, learner result, permission or audience effect supplied. | SubjectNest original Year 5 Science W05-06 · CC BY 4.0
Linear/no-print/no-touch/no-sound/optional tactile route: Describe source, blocker and receiving surface by role. The learner chooses an own shadow job/question. No-print/no-vision: name roles one at a time using familiar communication; no direct observation implied by an adult account. Optional local tactile shapes can represent these roles, not real light sensed by touch.
straight-path
Exact geometry/status: Point source0; bar4 from -1 to1; screen8; same axis scale60px per arbitrary unit; ideal rays meet screen -2 and2, ideal span4. No actual data.
Exact visible text in XML source order: An idea about light paths | Arbitrary model units; ideal rays, not actual lamp measurements. | SHADOW WINDOW · IDEAL POINT SOURCE | source 0 | bar 4 | screen 8 | Ideal rays pass the bar's edges in straight paths. | The ideal screen span is 4 arbitrary model units. | A real lamp may have a wide source and unclear edges. | What does this idea help you ask? | S5-SHADOW-WINDOW-01 · ORIGINAL MODEL / BLANK AID | SubjectNest by NeuroForgeIO Pty Ltd with Codex assistance | Created 30 September 2026 · computer-created teaching source | Purpose: model blocking; distinguish idea and observation | No actual trial, learner result, permission or audience effect supplied. | SubjectNest original Year 5 Science W05-06 · CC BY 4.0
Linear/no-print/no-touch/no-sound/optional tactile route: Read positions and the two straight edge paths in order, naming the span as an ideal prediction only. Direct an adult line or optionally use familiar tactile lines. No count/ratio/arithmetic/handling target. Ask what a wide real source/ambient light might change; no sound needed.
change-one
Exact geometry/status: Two same-scale27px-unit idea diagrams: source0/screen8 fixed; bar4 then2, same height2. Ideal spans4 then8, not actual observations or fresh C/D.
Exact visible text in XML source order: Change one thing on purpose | Arbitrary model units; real outcomes remain to be observed. | SOURCE AND SCREEN STAY; BAR POSITION CHANGES | FIRST IDEA · bar 4, screen 8 | source 0 | bar 4 | screen 8 | Ideal span 4 | CHANGED IDEA · bar 2, screen 8 | source 0 | bar 2 | screen 8 | Ideal span 8 | S5-CHANGE-ONE-02 · ORIGINAL MODEL / BLANK AID | SubjectNest by NeuroForgeIO Pty Ltd with Codex assistance | Created 30 September 2026 · computer-created teaching source | Purpose: choose one comparison, not supply actual data | No actual trial, learner result, permission or audience effect supplied. | SubjectNest original Year 5 Science W05-06 · CC BY 4.0
Linear/no-print/no-touch/no-sound/optional tactile route: Describe first and changed bar position while retaining source/screen. Name predicted qualitative size difference or use the exact model values if helpful. No-print/no-touch/no-sound: dictate one comparison or keep a plan; optional tactile layouts preserve source/bar/screen identity and equal scale.
record-a-try
Exact geometry/status: Blank actual record fields and three-column table: condition/source; actual available result; unclear/missing. Two blank entry spaces; no supplied result or trial-count quota.
Exact visible text in XML source order: What did we actually notice? | Blank optional record; no data, trial or permission supplied. | ACTUAL RECORD, ONLY IF A TRY OCCURRED | Date / source / question: _____________________ | Who operated? Who observed? What help? | Quantity / unit / edge rule, if useful: ___________ | Condition / source | Actual available result | Unclear / missing | Repeat only if useful. No trial-count quota. | Keep ideal predictions separate from actual results. | No try? Keep a plan; leave actual-result spaces blank. | S5-RECORD-A-TRY-03 · ORIGINAL MODEL / BLANK AID | SubjectNest by NeuroForgeIO Pty Ltd with Codex assistance | Created 30 September 2026 · computer-created teaching source | Purpose: keep available observations and their provenance | No actual trial, learner result, permission or audience effect supplied. | SubjectNest original Year 5 Science W05-06 · CC BY 4.0
Linear/no-print/no-touch/no-sound/optional tactile route: Read fields in order or keep a spoken/signed record with source/operator/help named. Leave actual results missing where no try/observation occurred. Predictions are labelled separately. Optional broad tactile column cues identify categories only, not results; no print/sound/handling necessary.
my-shadow-message
Exact geometry/status: Open purpose/intended-viewer fields and one blank rectangular idea area; keep/change/pause/stop plus actual/model/plan attribution prompts. No supplied finished design or response.
Exact visible text in XML source order: Make my shadow idea useful | Open drawing/description space; no finished product or effect supplied. | My shadow-picture / message / question: | ____________________________________________ | My purpose or inquiry alone: __________________ | Who might view it, if I want? __________________ | Keep / change / pause / stop | Actual made / actual observed / model / untested plan? | Who made or operated? What did I choose? | A reader's response stays open unless it happened. | S5-MY-IDEA-04 · ORIGINAL MODEL / BLANK AID | SubjectNest by NeuroForgeIO Pty Ltd with Codex assistance | Created 30 September 2026 · computer-created teaching source | Purpose: make a child-owned idea with an honest status | No actual trial, learner result, permission or audience effect supplied. | SubjectNest original Year 5 Science W05-06 · CC BY 4.0
Linear/no-print/no-touch/no-sound/optional tactile route: Choose one own shadow job or inquiry alone, describe/direct a mark or retain a no-material plan. Record actual adult/learner making separately. A chosen private purpose needs no audience; intended/actual response differs. Optional tactile outline is blank idea space, not child art or a performed shadow.
source-and-idea
Exact geometry/status: Three broad named rectangles vertically: actual view; attributed account; idea model/plan. No supplied human/cultural account or mandatory sorting exercise.
Exact visible text in XML source order: Use the source honestly | Original source-status aid; not a supplied human/cultural account. | WHAT KIND OF SOURCE ARE WE USING? | ACTUAL VIEW | What the learner actually accessed; name the setup/help. | ATTRIBUTED ACCOUNT | Someone else's actual description; keep their source. | IDEA MODEL / PLAN | A diagram or proposal; no actual trial implied. | A model purpose is the maker's intent, not an achieved effect. | Missing observation or reader reply stays open. | S5-SOURCE-AND-IDEA-05 · ORIGINAL MODEL / BLANK AID | SubjectNest by NeuroForgeIO Pty Ltd with Codex assistance | Created 30 September 2026 · computer-created teaching source | Purpose: name the source when it helps, not audit every turn | No actual trial, learner result, permission or audience effect supplied. | SubjectNest original Year 5 Science W05-06 · CC BY 4.0
Linear/no-print/no-touch/no-sound/optional tactile route: Name the actual source kind when useful, then return to the child's work. Use a spoken/signed label or familiar symbol; no-print/no-vision/no-touch/no-sound alternatives retain attribution and missing-evidence meaning. Optional tactile rectangles identify categories, not source events.
fresh-c
Exact geometry/status: Unanswered new ideal source0/bar2 endpoints-1,+1/screen6. Same axis scale60px per arbitrary model unit. Receiving line extends y=-4 to4 (not a projected shadow); no rays/projected shadow/result/permission supplied.

Linear/no-print/no-touch/no-sound/optional tactile route: Describe all exact source facts and invite the learner's first own question/change/prediction/plan. No numerical projection or actual trial required. Optional familiar tactile positions preserve these relationships; do not add a shadow answer. Capture first component/help, then optional further work/later sitting; unfinished not yet observed, no speed score.
fresh-d
Exact geometry/status: Two unanswered same-scale24px-unit configurations: before source0/bar3/screen9; proposed after source0/bar2/screen6; same centred bar height2. Receiving lines extend y=-4 to4 (not projected shadows). No projected shadow or actual result. Proposed cause claim printed as a claim, not a finding.
Exact visible text in XML source order: Fresh D · a new comparison plan | Ideal model proposals; no completed shadow answer or actual result. | NEW D · AN UNPERFORMED COMPARISON PLAN | BEFORE IDEA · source 0, bar 3, screen 9 | source 0 | bar 3 | screen 9 | PROPOSED AFTER · source 0, bar 2, screen 6 | source 0 | bar 2 | screen 6 | Same bar height 2; same arbitrary model scale. | Claim: "It will be bigger because the bar is closer." | What could you change in this plan? Why? | S5-NEW-PLAN-D-06 · ORIGINAL MODEL / BLANK AID | SubjectNest by NeuroForgeIO Pty Ltd with Codex assistance | Created 30 September 2026 · computer-created teaching source | Purpose: invite an own revision; no trial/result/permission supplied | No actual trial, learner result, permission or audience effect supplied. | SubjectNest original Year 5 Science W05-06 · CC BY 4.0
Linear/no-print/no-touch/no-sound/optional tactile route: Read before and after positions, shared size/source, then the exact proposed claim. Invite one first own revision/question/reason; several valid changes and own sources welcome. Optional familiar tactile layouts keep equal scale but dictate no physical movement.
