The Reason for the Seasons: Tilt, Daylight and the Solstice

Is summer when Earth is closest to the Sun? Students test the idea with real 2026 orbit distances and city temperatures from both hemispheres, walk a human orbit, graph real solstice day lengths from the Arctic to Tierra del Fuego and work out why a high Sun heats more than a low one. Nothing to buy: just the printed sheets and the room.
