Two different paper model jobs · full no-image alternativeYear 2 Science · T1 W7–8 · Aids / O03 two model jobs
Source review complete · local suitability still needs review.
TURN / day-night question: turn an unshaded marked Earth disk in place. Keep the separate Sun-facing guide fixed.
ORBIT / about-year question: move a separate Earth token around a Sun-labelled outline. Turning in place and travelling around are different operations.
These are explanatory paper models, not to scale. No lamp, calibrated time, sky distance, actual year collection or visibility prediction. About-month appearance is a separate question.
