Kids 8–10, new to the idea · Watch four short animations: the distance myth, a flashlight on a wall, Earth's tilted trip around the Sun, and day length. Then drag Earth around its orbit to give kids around the world the right season.
Earth's tilted axis leans each half toward the Sun in turn, which makes sunlight straighter and days longer there, so tilt (not distance) makes the seasons.
