Topic 6 "How heat moves from hot to cold" — your read (2 October 2026)
Skim first
The lessons in teaching order, each with its one rule sentence; then the intro script; then the question types. The review page follows.
The lessons and their rules
| Lesson | Atom | Rule sentence |
|---|---|---|
| L01 Which way heat moves | ENE4-020 | Heat moves from the hotter thing to the colder thing. The same temperature: no heat moves. |
| L02 What happens to the temperatures | ENE4-021 | The hotter thing's temperature goes down. The colder thing's temperature goes up. The same temperature: heat stops moving. |
| L03 Heat conductors and heat insulators | ENE4-022 | Metal lets heat through quickly: a heat conductor. Wood, plastic and cloth slow heat down: heat insulators. |
| L04 Why metal feels colder than wood | ENE4-023 | Metal and wood in one room: the same temperature. Metal moves heat out of your hand faster. So metal feels colder. |
The intro script (118 words, about 59 s)
Here's Carla coming in from the snow, into Miss Hughes's warm classroom. Her hands are cold. She wraps both hands around a mug of hot cocoa. Slowly her hands warm up, and the cocoa cools down. Then she touches the metal leg of her chair, and it feels so cold. But the wooden seat does not feel cold, and both have stood in the same warm room all night. Where did the heat from the cocoa go, and why does the metal feel colder than the wood? To find out, we will look at which way heat moves, what happens to the temperatures, and why metal feels so cold. Okay, so are you ready to follow the heat?
The question types (from TYPES_G4T06.md)
- Type 1 (easy (2 medium) · MCQ; three drawn as thermometer pairs · ENE4-020): two touching things, one hotter (or shown): which way does heat move — from A to B / from B to A / both ways at once / no heat moves
- Type 2 (medium · MCQ · ENE4-020, 021): a hand feels cold, or a temperature went down: what is moving / why — four happenings; "cold moves in" and "it has no heat" are the distractors
- Type 3 (easy (3 medium) · MCQ · ENE4-021): what happens to one thing's temperature; what the PAIR does; what the partner's temperature did when one reading moved — goes up / goes down / stays the same / up then down · "The milk gets colder and the water gets warmer." (four combinations, plain sentences)
- Type 4 (easy → hard · MCQ; one drawn · ENE4-021): when heat stops; what is true then; which number both could read at the end (between the starts) — as listed
- Type 5 (easy, medium · MCQ · ENE4-022): which material is a heat conductor / insulator; which part of a pan lets heat through quickly; what a pot handle getting hot tells you; which kind of material the pie pan / the clothespin is — four materials or objects, or conductor / insulator / maker / stopper (the sister set; "heat carrier" is Topic 4's coined word and never a distractor here)
- Type 6 (medium · MCQ · ENE4-022): pick the kind of material, or the container, for a job — conductor / insulator / maker / stopper; a thick foam bag against three metal containers
- Type 7 (medium, hard · MCQ · ENE4-022): why the stuffing / the blanket keeps a thing warm; why the pan lid burns and its wooden knob does not; which ice cube melts first (the stem says ice melts when heat moves into it) — four single-statement reasons or four outcomes
- Type 8 (hard · MCQ keyed on the term · ENE4-022): metal lets heat through quickly / cloth slows it: what kind of material is it called — a heat conductor / a heat insulator / a heat stopper / a heat maker
- Type 9 (easy → hard · MCQ; one drawn pair · ENE4-023): which feels colder; which is at the lower temperature; why; what two taped thermometers show; the reversed case (both hotter than the hand: which feels hotter, and why) — as listed
- Type 10 (medium, hard · typed text · 020, 021, 023): finish the rule: the missing word — colder (cooler) · down (lower) · same (equal)
Four lessons: heat moves from the hotter thing to the colder thing; the temperatures change as it moves, until they are the same; some materials let heat through quickly (heat conductors) and some slowly (heat insulators); why a metal thing feels colder than a wooden one in the same room. Every key agreed by two cold readers and every changed item re-read; the figure review (every thermometer reads true) and the guidance-and-accuracy review are applied. Pictures are placeholders until you answer.
The three the author put to you (built as recommended)
1. Does the L02 video say the end temperature sits between the two starts?
A learner may choose the video alone, and two items rest on the fact.
Built: the video says "After fifteen minutes, both read seventy degrees Fahrenheit, between forty and one hundred."
Recommendation: yes.
Yes / article only
2. Is "heat moves" the verb, never "heat flows"?
"Flows" pictures a liquid and feeds the heat-is-a-stuff belief; "moves" is plain and true. The atom's title keeps "flows" (your register wording, not student text).
Built: "moves" in every student line.
Recommendation: moves.
Moves / flows
3. Do thermometer chips keep "70 °F" while the prose says "degrees Fahrenheit"?
Grade 3 Topic 17's instrument card introduced the symbol, which is the exception the units rule allows; on-screen numbers are numerals by your 2 October refinement.
Built: the symbol on chips, the words in prose.
Recommendation: keep.
Keep / words on chips too
The lessons
4. L01 Heat moves from hot to cold — Carla's hand on the cold window: nothing moves into her hand; heat moves out of it into the glass. A cold spoon in hot soup, ice in water: the direction is always hotter to colder. page
5. L02 The temperatures change as heat moves — a cup of hot water in a bowl of cold water, a thermometer in each: 100 and 40, then 84 and 56, then 70 and 70, and heat stops moving. page
6. L03 Heat conductors and heat insulators — metal, wood, plastic, foil, cloth: which lets heat through quickly and which slowly; the terms coined last, after the sort. page
7. L04 Why metal feels colder — a metal chair and a wooden chair in the same room are the same temperature; metal moves heat out of your hand faster, so it feels colder. page
Applied without asking
Heat carries energy from a giver to a receiver (Topic 4's words); "cold" never moves except inside a claim a child judges; the material cards' chips now read QUICKLY / SLOWLY until the sort table coins the terms; the L01 video says "nothing moves into her hand"; the one bank item that tested another atom cut (bank 51); one TRUE claim added so the claim string is mixed; a scarf-style "heat maker" belief as a distractor, never a taught label; 51 items, 12 to 14 per atom; summary before practice; six picture placeholders with briefs.

After you answer
Nothing on the page changes if you keep all three; "flows" or "words on chips" is a one-hour text pass. Either way the picture pass starts, and the six-video batch goes with Topic 1's on your word.
