# Day 34 · Two views of one night question

**Child start:** “Tell the view from the ground. Then show what your model is trying to explain.”

**Useful finish:** A paired ground-view/model explanation. **Prerequisite:** Day 13 turning disk with separate stationary facing guide; Day 33 reference. **Prepare:** Unshaded marked Earth disk, separate fixed Sun-facing guide and Sun label; three fictional ground-view star-pattern cards. No lamp. **Opportunities:** U01/H01/I04/I06; I02 actual model operation only.

**Complete model:** In invented ground frame T, same three-star group is low-left at early evening, higher-centre at later evening, and farther right at a still later named record on the same fictional night; group shape is unchanged over this model interval. Separate space-view model turns a marked Earth disk while its facing guide stays fixed. Explain that Earth's turning changes our ground view. The cards are not a real constellation, latitude, exact compass path, night date or visibility forecast. Stars have their own motions; the model does not prove they are fixed in space.

**Run:**2 min ask what a visitor needs explained;3 min use only one disk turn and match one ground record;7 min route;3 min ask which item is supplied record and which is explanatory model. Extend with one willing visitor4 min, correction3 min and a not-to-scale label3 min.

**Route1 — Act as model director:** Move/direct the disk, keep guide stationary and tell the same-place story; sit/point/speak options. **Route2 — Edit a comic:** A draft says “the stars circle a motionless Earth”; replace with a ground-view explanation linked to the separate turning model while preserving the supplied positions. **Route3 — Record two voices:** Dictate/sign a ground observer's supplied description and a model maker's explanation. The two roles are fictional; no recording file needed.

**Notice/next:** Describe the supplied positions and limit of the model. If ground/model are equated, add explicit source labels before another explanation. B-first after this teaching; remember all reference/turning mechanics are familiar from 03–04. Home H04; C07–08; X04.
