Dr. Natalie Batalha tells children how astronomers of the NASA Ames Research Center find Earth-like planets. She invites students for the lesson: http://whybluesky.net/lesson-plans/lesson-plans/science/how-to-weigh-the-earth made available by WhyBlueSky.

During the class students will learn experimentally what the force of gravity is and how it acts. They will also drop different objects and check whether they fall equally quickly. Finally, they will calculate the mass of the Earth.
