The lessons and their rules
| Lesson | Atom | Rule sentence |
|---|---|---|
| L01 What the brain does: it takes in messages and decides | LIF5-058 | The brain takes in messages from the senses. It decides what the body does. It sends messages to the body. Thinking and remembering happen in the brain. |
| L02 The sensory organs: what each one gathers | LIF5-059 | The eyes, ears, nose, tongue and skin are the sensory organs. Each one gathers one kind of information. Each one sends it to the brain. |
| L03 What the skin does: a covering that keeps germs out | LIF5-063 | The skin covers the whole body. It keeps germs out. It gathers touch and warmth. It helps keep the body at the right warmth. |
The intro script (111 words, about 56 s)
Here's Cleo in the kitchen at home. The oven timer rings, and she turns toward the oven. She opens the oven door. Her face feels the warm air, and she smells the cookies. So she knows they are done. Her ears, her skin and her nose each noticed something. But how did what they noticed reach her hands and her feet, and what was the brain inside her head doing? To find out, we will look at what the brain does, what your eyes, ears, nose and tongue do, and the jobs of your skin. Okay, so are you ready to find out how your body finds out about the world?
The question types (from TYPES_G5T32.md)
- Type 1 (easy · MCQ, the four-organ set · 058): a scene with a sense and an action: which organ decided — the brain / the heart / the stomach / the lungs (the key is always the brain, so the set rotates its order)
- Type 2 (easy · MCQ · 058): where the message from a named sense goes; where the brain sends a message — four destinations (to the brain / to the feet / to the heart / to the hands; to the arms and legs / to the ears …)
- Type 3 (easy · MCQ, the four-organ set · 058): which organ is doing the remembering or the thinking — the four body organs
- Type 4 (medium, hard · MCQ · 058): which step of the chain happens second; which sentence about a thinking brain is true; three jobs chained in one scene — four statements of one shape
- Type 5 (medium, hard · MCQ drawn (the stacked chain card with one box blank) and typed · 058): what goes in the empty box (first or last); the organ typed from its whole job; the word for what travels to and from the brain — four one-sentence steps; accept lists BRAIN / MESSAGE
- Type 6 (easy · MCQ, four of the five organs · 059): a fresh scene names a sense: which organ gathers it — four of the eyes / ears / nose / tongue / skin
- Type 7 (easy · MCQ, four of the five kinds · 059): which kind of information a named organ gathers — four of what things look like / sounds / smells / tastes / touch and warmth
- Type 8 (easy, medium · MCQ · 059): where an organ sends its information; two kinds of information in one moment, which organ gathered the named one — four destinations; four organs
- Type 9 (medium · MCQ drawn (an item table, one cell '?') · 059): the missing organ or the missing kind of information — four organs or four kinds
- Type 10 (medium, hard · MCQ and typed · 059): which organ did the deciding after a sensory organ gathered; where two organs' information goes; the term applied to a fresh organ among sister names (RECALL_BY_MCQ, medium); the definition applied to four organs (hard); an organ typed from the information it gathers — four organs; a sensory organ / a food organ / a pumping organ / a breathing organ; accept lists NOSE / TONGUE / EYES
- Type 11 (easy · MCQ · 063): which organ covers the whole body; what whole skin does about germs; what gets in through a cut — four organs; four happenings; germs / sweat / warmth / messages
- Type 12 (easy, medium · MCQ · 063): which organ made the sweat; why a break in the skin is washed; what is true of germs on whole skin; what happens as sweat dries; why the skin makes sweat — four single-statement reasons or happenings
- Type 13 (medium · MCQ · 063): the skin as a sensory organ: which organ gathers the warmth or the cold; where it sends it; which job is lost at a scratch — four organs; four destinations; four jobs
- Type 14 (hard · typed and MCQ · 063): the organ typed from its three jobs; 'germs' typed from its description; two cases judged against both halves of the rule; the bandage's job inferred; two jobs ordered in time — accept lists SKIN / GERMS; four single statements
Three lessons for three atoms, in Miss Fontaine's class with Cleo, Dalia and Eli.
Cleo's bike stops in less than a second when a dog runs out, so L01 teaches that what her eyes saw went to her brain as a message, her brain decided to stop, and her brain sent a message to her hands; thinking and remembering happen in the brain too.
Dalia sits by a campfire and five things reach her at once, so L02 builds a table one row at a time — the eyes gather what things look like, the ears sounds, the nose smells, the tongue tastes, the skin touch and warmth — and each one sends it to her brain; then the name: an organ like this is called a sensory organ.
Eli scrapes his knee at soccer practice and the coach washes it at once, so L03 shows the same knee whole and scraped: whole skin keeps germs out, a gap lets them in; the skin gathers touch and warmth (and cold), and when he gets hot his skin makes sweat, and he cools down as it dries.
The register's hot-pan example is not used — a hand pulled off a hot pan is a reflex, not the brain deciding — and nothing about nerves, brain regions or reflexes is said.
The non-author review found two things that had to change (the skin lesson called the skin "the one organ you can see" a lesson after the eyes, ears, nose and tongue were shown as organs; one bank item had two defensible "second" steps) and fourteen worth fixing, all fixed. Two cold readers then agreed every key but one: a bank item whose answer hung on a verb ("took in the message") rather than on where remembering and deciding happen; it is re-written and its key changed, and their seven smaller flags are applied (one two-defensible item re-asked, self-made organ labels replaced, a typed item's accept list widened, a heating chain straightened, two retrievals marked). A re-read of the changed ids is owed. Pictures are the seven cartoon placeholders until the text is through review.
Questions for James
None. Every call the author made (the capstone in the middle because the row fixed the order; the long skin and senses articles; "germs" explained but not coined; the skin named as an organ Topic 30's "inside the body" definition misses; the hot-pan reflex left out; the title taking "the") is one his answer would not change a student's learning by, or is a ruling he has already given. The author's note that the knowledge graph's LIF5-058 example (the hot pan) is a reflex is filed as PROPOSED for that session, not applied.
Applied without asking
8 Oct 2026, the non-author review (text is cheap; nothing scientifically contested): the skin lesson's line "the one organ you can see" became "It covers Eli's whole body, from his head to his feet"; a line "The skin gathers warmth, and it gathers cold too" sits before the ice pack; the skin video now says some germs can make you sick (149 words); the campfire return reads in short sentences; three brain-quiz stems say "which part of" where the options are a tail, a neck or hands; the rabbit item asks what happens next after the message reaches the brain; the fox and goalkeeper cards' distractors no longer repeat boxes drawn on the card; the planning item's four options are all about her brain; the muddy-soil item names what its options are about; the kitten-scratch stem is active; the playground item's four options share one shape; the one-step definition pick tagged hard became a fresh case (a bear's ears) tagged medium and moved into its block; the summary still puts each heading chip over its own thing and uses this topic's message card; the side-by-side skin pair is readable on a phone.

After you answer
Nothing waits on you. The re-read of the changed ids runs now on blind/2026-10-08-adjudicated/ (ids in its CHANGED_IDS.md); once those agree, the picture pass starts on the seven placeholders, and the five-video batch (built and checked, not sent) goes on the coordinator's word after your Grade 5 sample.
What the review found, and what changed
The blind read (two readers, 8 October) and the adjudication
Two readers answered 101 items cold and agreed every key but PP-43, where both read "her ears took in the message" as fair; the item now opens every option "Her ears gathered the sound" and differs only on where the remembering and the deciding happened (key changed). Their flags, all applied: the rabbit item re-asked from the decide step; "food / pumping / breathing organ" labels replaced with plain wrongs in the practice and the bank; the four-organs item no longer prints the ears' job; the hot-sand item is a heating, sweat, cooling chain; the typed "message" item accepts "information" and "signal"; the two retrievals name an earlier topic in their why; ⟂ draw constraints on the type sheet. Order item and typed answers all matched. Section "Adjudication" in REVIEW_G5T32_2026-10-08.md.
The non-author review (8 October): two must-fix, fourteen worth fixing, ten left as simplifications
The science is right at the Florida 5.L.14.1 level, the reviewer said: the brain takes in messages, decides and sends messages; the five sensory organs each gather one kind of information and send it to the brain; whole skin keeps germs out, gathers touch and warmth, and cools the body as sweat dries. The hot-pan reflex was rightly left out (a spinal reflex, not the brain deciding — a biologist would strike it). The ten Grade 4 faults are absent; no child voices a claim; nothing is lettered.
Fixed: the skin called "the one organ you can see" (false after L02's visible organs) now covers the whole body head to feet; cold is said to be gathered before the ice pack appears; the skin video says some germs make you sick, so the washing has a reason a viewer hears; the campfire return in short sentences; three "which organ" stems over non-organ options; the rabbit "second step" item with two defensible answers; the fox and goalkeeper cards' restated distractors; the planning item's eyes option; the muddy-soil ask; the kitten-scratch passive; the playground key that alone lacked "only"; the one-step definition pick retagged medium on a fresh case and moved (PP-33–PP-42 are now PP-34–PP-43); the summary still's chips over the wrong boxes; the skin pair's phone size; two stale key strings on the For James box; a stale bank header.
Left: the eyes and skin as "organs" against Topic 30's "inside the body" definition (the member named, the definition not widened); "touch and warmth" as the skin's kind of information (pressure and pain are beyond the benchmark); the hot-sand order item (true in time); the two long articles (a subtitle or figure every five lines); the rule card re-printed under the rule block (17 of 34 Grade 5 topics do it); "got the message"; the typed MESSAGE item marking "information" wrong (the word for both directions); "his mouth" as an organ option; no figure in L03's return; the 25 unusual words.

The bank, in brief
52 items in content/G5T32_pp100_bank.py: 45 four-option MCQs and 7 typed words (brain, message, nose, tongue, eyes, skin, germs). Per atom: LIF5-058 14 · LIF5-059 22 · LIF5-063 16. Easy 20, medium 20, hard 12, sorted easy to hard; the capstone carries the most items, the last atom the hardest share. MCQ keys A 10 · B 13 · C 12 · D 10. Fourteen question types, one exemplar each on the type sheet. No claim item anywhere (the register names no belief for these atoms). Every scene is fresh against the lessons, quizzes and practice (the scene-noun grep is in the build record; the review's bear is new).
