# Day 37 · A turn, a month and a year

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

## Your notes

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.

## Pick one way

**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.

You can ask a grown-up to read or write exactly what you tell them. Do a small useful part, rest or pass. A made-up note is not a real sky sighting.
