Topic 15 "Light and warmth" — your read (28 September 2026, night)

Three lessons, one per atom: something that gives light is usually warm too · light carries energy to whatever it lands on · when two things rub together, both get warmer. Written by the author as you, then a non-author review (33 findings, 33 applied) and one cold read of every changed and new item (21 of 21 keys agreed; two flags fixed and re-read, both agreed again). Reply by number.

The three that need your word

1. Is the student's title "Light and warmth"?

The architecture calls this topic "Light and heat", and the three atoms' register titles say "heat" too.

Your Topic 11 ruling struck "heat" from every sentence a student reads; the lessons say warm, warmer, warms up, hot and warmth, and never "heat".

The reviewer and the coordinator settled on "Light and warmth" — a plain noun phrase in the topic's own word. The register's titles stay as they are.

Recommendation: "Light and warmth". Keep / allow "heat" as a title word / say the title you prefer

2. Do the seven question types stand — and the two typed hard items in particular?

Your ruling of tonight is applied without asking: the bank's hard items are text entry, not multiple choice. Each takes two steps and prints nothing it asks for:

• A wall faces the Sun all morning and gets warm. Nothing touches the wall. What carries the energy from the Sun to the wall? — types light (sunlight, the Sun's light and their spellings are accepted). Most children will type "the Sun", the source; the key is the carrier.
• Lorcan rubs two sticks together, fast, and the sticks warm up. What kind of energy did the moving sticks have? — types mechanical energy, Topic 11's term: the child supplies that the sticks were moving.

Five easy and medium types are four-option multiple choice. The reviewer caught that the first type was answered by "which thing gives light" alone; it now asks "Which thing is warm?" so a child who thinks light-givers are cool has no warm thing to pick. Every atom is tested on its own; no atom carries more than two types.

3. Does the glow stick stay as the "usually" case?

The atom says light-givers usually give heat. Lesson 1 shows one that does not — a glow stick gives light and stays cool — and adds that a firefly is another, so "usually" means something a child can check.

One quiz item and one practice item test it; the rest of the lesson is flames, a bulb and the Sun.

Recommendation: keep. Keep / strike

Applied without asking: the lesson order 020 → 033 → 021 (the two light lessons together, rubbing last) · the rubbing rule reads "When two things rub together, both get warmer." · a shaded seat is "in the shade — the Sun's light does not reach it", never "no light lands on it" (Topic 13 taught that light lands on everything you can see) · warmth is never a stuff that flows: the hot bulb "gives some of its energy to the air", and "there is no such thing as cold leaving your hands" · hard bank items are typed · every attached question stands alone with its own drawing · figures carry an image kind (drawn / cartoon / photo) · student names checked against every other topic.

The lessons

4. L01 Things that give light are usually warm too — a lamp's old glass bulb is hot after an hour; the same lamp switched off is dark and cool; a candle, a campfire, the Sun; then the glow stick that stays cool. Article · script · quiz Fine / say where

5. L02 Light carries energy — a bike seat left in the sunshine is hot; the same bike in the shade of a tree stays cool; a sun stripe on a floor is warm inside and cool beside; a lamp's light warms a stone; a cat finds the warm spot. Article · script · quiz Fine / say where

6. L03 Rubbing warms things up — cold hands rubbed warm; the same hands pressed still stay cold; the moving hands had mechanical energy (Topic 11) and gave some of it to the skin where they rub; an eraser on paper; a stick on a log. Article · script · quiz Fine / say where
