Classroom demonstration shows how craters were formed on the moon.
Instructional Procedures Activity
Curriculum Extensions Activity
Big rocks from space hit the moon, leaving holes called craters. The moon is made up of lots of gray. There are no animals and plants because there is no usable water or air. What are those light and dark areas on the moon's surface? The light areas are called highlands or mountains. The dark areas are flat, low plains. Most of the small craters on the moon were formed by the impacts of meteoroids crashing into the moon's surface. The larger craters were probably formed by larger celestial bodies (like asteroids and comets) hitting the moon's surface. The largest crater on the moon, the Imbrium Basin, is 700 miles wide.
