# C13 · The school timetable and the orbit

Prepare a pretend attendance list and a source-linked “Earth orbit about a year” caption. Child makes a display that does not confuse the two. Worked reasoning: attendance tracks sessions; the caption describes a physical orbit timescale from a primary source. Ten attended lessons don't evidence a year of actual observing. Finish with a clear question beside each. Next help: separately turn a paper marked Earth disk and move a token on an orbit outline to name different model jobs, not calculate a calibrated orbital speed.
