Topic 3 "Earth pulls things down" — your read of the rebuilt topic (28 September 2026, night)
Rebuilt to your review: six lessons over five atoms, two of them new in the register. A non-author reviewed the new lessons (20 findings applied) and read every item cold, 61 of 61 keys agreed. Your rulings already given are applied without asking: every atom tested alone and in a pair, four options on every MCQ, "gravity" names the happening and the force is Earth's pull, and (28 Sep, night) the bank's hard items are typed, not MCQs. Reply by number.
New since your typed-entry ruling
1. Do these typed hard types work for you? You said hard PP100 questions should be text entry, so both hard types are now typed: the student types the answer and an exact-match check reads it against a list of the lessons' own words. Type 8 is new (Omar's claim MCQ had no typed form; the claim itself stays in L05's quiz). Type 9 keeps its gymnast and loses its options. The topic has no numbers, so no numeric type.
- Type 8 (always pulling + a push beat it): "A grasshopper pushes off a leaf and jumps up. While the grasshopper is going up, what is pulling on it? Type your answer." Accepts Earth's pull / the Earth's pull / Earth / the Earth / gravity / Earth's gravity, with and without the apostrophe.
- Type 9 (straight down + every part): "A gymnast hangs upside down from the rings. Which way does Earth pull her hair? Type the direction." Accepts straight down / down / downward(s) / toward(s) the floor or the ground, and their joins ("straight down toward the floor").
The two typed exemplars, with their accept lists and hard-because lines Both work / change the scene / change the accept lists / one of them should be an MCQ after all
The one that unblocks the bank
2. Do the nine question types stand? Built from the lessons' own forms with four options, plus two harder types; the coverage table shows every atom tested alone and in a pair. Your thrown ball / traveling rocket / moving car item is type 3, testing "always pulling" and "straight down" together.

The two new lessons
3. L02 Earth is always pulling — a book on a table, a ball on its way up, a moving car, a falling leaf; rule last; the quiz asks "Is Earth pulling on it?" of still, up, sideways and down cases, always yes, with two children's wrong claims keyed no. Article · script · quiz Fine / say where
4. L03 Earth pulls straight down — rising ball, flying rocket, moving car, hanging lamp; "Which way does Earth pull?" always straight down toward the ground. Article · quiz Fine / say where
The changed lessons
5. L01 now says, right after the coining: "This pull happens because of something called gravity. You will find out more about gravity later in the course." L01 Fine / say where
6. L05 A strong enough pull — the hand-and-ball and every two-pull figure now draw the winning arrow longer; the hand is marked for David's image pipeline (the drawing is a placeholder). L05 Fine / say where
7. L06 Earth's pull is called gravity — the closer, then a quiz that retests the whole topic in the word gravity. L06 · quiz Fine / say where
One wording question, both sentences yours
8. L01 says gravity CAUSES the pull ("This pull happens because of something called gravity"); L06 says the pull IS gravity ("Earth's pull is called gravity"). Two relations for one word. Either is fine at grade 3, but you may want one. Keep both / L06's only / L01's only
After you answer
1 and 2 → bank of about 50 from the approved types (mostly easy MCQs; the hard items typed) with the coverage table, blind read, hand-over folder for David (his image pipeline gets 19 GENERATE briefs for the people and hands).
