# Day 37 · A turn, a month and a year

**Child start:** “Choose the time story. A turn? A longer Moon record? A trip around the Sun?”

**Useful finish:** A three-question time menu. **Prerequisite:** Day 13 turning; Day 32 about-month appearance; Day 35reference. **Prepare:** Paper Earth mark +fixed guide, separate orbit route outline and four caption cards; no model distance/ speed measurement. **Opportunities:** U01/H01/I04/I06.

**Complete model:** Card D describes one day/night turn of the same Earth place; M is the original about-month lit-appearance archive from Day 32; Y says Earth completes a trip around the Sun in about a year; a separate miniature paper orbit is only a model. A ten-session attendance list is not evidence that a Moon phase cycle or Earth orbit has been observed. About a month is not always an exact calendar month. Do not teach the simplified “every fourth year” leap rule or 23.9-hour sidereal figure here. Year and day are different motions; seasons are not explained by Earth being nearest the Sun.

**Run:**2 min choose one interesting time question;3 min contrast the two Earth motions using separate paper operations;7 min route;3 min choose which records would answer it. Extension label what would require a longer plan outside this bank rather than pretend to have completed it.

**Route1 — Direct two separate model jobs:** First turn the marked disk, then separately move an Earth token around the Sun route; child narrates the different purpose/time meaning. **Route2 — Fix a calendar exhibit:** A draft says “ten lessons make one whole Moon cycle”; replace it with the archive's actual scope and a longer collection plan. **Route3 — Make an audience menu:** Give a visitor three question cards and let them select an appropriate record/time span. Don't require memorised numerical durations.

**Notice/next:** Motion/time/question matched, model not observation. If turn/orbit collapse, teach one token action at a time. If calendar month treated as exact phase cycle, compare named calendar dates with an approximate cycle statement, without making a forecast. A-later after this teaching. Home H07; C13–14; X07.
