Fifth graders have made sense of how gravity plays a pivotal role in keeping the planets in orbit around the sun. In fact, the gravitational pull of the Sun keeps the planets in a circular orbit despite the planets wanting to go in a straight path.
But what else does gravity "do?" Knowing that if we were to jump up on the Earth anywhere, we'd always land "down." But is "down" the same for everyone? How can we explain how gravity plays a role on what happens to us when we jump? And is there a better way to explain this phenomenon?
