Description

Objects on the Moon weigh less than they do on the Earth because the gravitational field strength is much less. On the moon, astronauts can jump higher and leap farther than on Earth. Gravitational field strength is in direct relation to the size of a planet.

Classroom Ideas

This clip could be used to support lessons on space, weight and gravity. Students could discuss the weight of a given mass on different bodies in the solar system. While the clip mentions the size of planets, students should also consider the relationship between the mass of a planet and its gravitational field strength. The clip could lead into discussion of orbits, satellites and tides.
