Job: choose a shadow-picture/message or a question; notice one actual effect. Ready: approved gentle light, broad opaque card and pale screen, or light-parts description. Say: “What could our shadow do?”
- 0–3: Offer shadow-picture, a pretend doorway/message, inquiry alone or an own idea. Agree whether actual light is wanted; an adult can do all positioning. Stop remains available.
- 3–8: Make one brief actual shadow encounter in the approved setup. Invite “What do you notice?” Accept unclear/soft/dark/changed or no available observation. Ask the learner which part interests them; do not supply a measurement or pretend they operated equipment. Without apparatus, encounter the source description and choose an own question instead.
- 8–12: Name the light source, opaque blocker and receiving screen in this setup. Explain that blocked light can make a darker area; other light can still reach it. Introduce the ideal drawing only after the actual/source encounter, with its model label.
- 12–20: Follow one chosen idea: a broad shadow shape, a doorway-like gap between safely positioned broad cards, or a question about size/position. Learner observation/direction can be the meaningful work. Try only locally approved changes; a proposed change can stay a plan.
- 20–25: Ask “Keep, change or stop?” Notice one actual choice and one available observation/source response. Next invitation: ask which part makes the light. A nice supplied picture is not an observed learner result.
