An adult may read or describe exact source facts; use your usual communication. One meaningful first part can be captured before another part. You can choose an own question/source, vary or reject the idea. No unique wording, numerical shadow calculation, actual trial or finished project required. Apparatus work is optional and needs ordinary local review. An unfinished response means not yet observed; another short sitting is available, with no completion-speed score. These do not certify a whole code or Science year.
Fresh C — a new shadow question
Source S5-NEW-QUESTION-C-05. Original computer-created ideal point-source model, SubjectNest by NeuroForgeIO Pty Ltd with Codex assistance, 30 September 2026. Purpose: offer a new setup for an own investigable question/prediction/plan. No actual experiment, person/community account or achieved effect supplied.
The new C picture has point light source (0,0), opaque vertical bar at x=2 from y=-1 to y=1, and receiving screen at x=6. These are arbitrary model units and ideal rays, not centimetres or instructions for a room/body. No screen shadow answer or actual lamp observation is drawn. A real lamp may have a wide source/ambient light and unclear edges. Exact no-print description is in alternatives.
First: “What would you like to find out? What might you change?” Give one own question/change, prediction/reason or plan part, using any available mode. An own source/question or rejecting this model is welcome. The adult captures your first response/help before teaching examples or another component.
After first capture, if wanted: say what would stay and what you would notice, make a prediction/model, plan a locally reviewed actual try, or return in another sitting. No actual trial, measurement or permission comes with this brief. A plan stays a plan if unperformed; actual observations/operators are separately recorded when they occur.
Fresh D — a new comparison plan
Source S5-NEW-PLAN-D-06. Original computer-created ideal point-source proposal, same creator/date. Purpose: invite an own revision/reason about a new comparison. It is unperformed; no earlier child/adult trial, measured result, person/community account or local permission supplied.
The new D picture shows two configurations in the same arbitrary model scale:
| Configuration | Point source | Vertical opaque bar | Receiving screen |
|---|---|---|---|
| Before idea | (0,0) |
x=3, endpoints y=-1 and y=1 |
x=9 |
| Proposed after idea | (0,0) |
x=2, same endpoints/size |
x=6 |
Proposed claim: “It will be bigger because the bar is closer.” This is a claim about the idea, not a supplied observation. The drawings do not show a completed shadow answer. Ideal model rays do not promise actual lamp measurements, and these numbers dictate no real body direction/range/room distances.
First: “What could you change in this plan? Why?” Offer one own revision/question/reason or identify what evidence is missing. Several valid comparisons/own choices are possible; no particular position, left/right choice, numerical calculation, phrase or all-conditions checklist is required. Capture the first available component before further prompts/examples.
After first capture, if wanted: choose what would change/stay, predict or describe what to observe, make an own model, or plan an approved actual comparison later. Keep actual observations and operator roles separate. You can stop with a useful question/plan and return another time.
Teacher key and exact model data are separate teacher resources. A first independent/support-attributed response is not rewritten as if later teaching had already happened.
