Planets and the solar system
ScienceGrades 2–524 clues and answers
Twenty-four clues covering the eight planets, the Sun and Moon, and the words that come up in every space unit: orbit, gravity, comet, meteor, asteroid and eclipse. The clues describe rather than define, so students have to think about each object, which makes them good for bingo, a review race or a quiz.
