![]() ![]() This activity focuses on the following Three Dimensional Learning aspects of NGSS:ĭevelop and use a model to describe phenomena.Īlignment agreement: Thanks for your feedback!Įarth and its solar system are part of the Milky Way galaxy, which is one of many galaxies in the universe.Īlignment agreement: Thanks for your feedback! The solar system consists of the sun and a collection of objects, including planets, their moons, and asteroids that are held in orbit around the sun by its gravitational pull on them.Īlignment agreement: Thanks for your feedback! The solar system appears to have formed from a disk of dust and gas, drawn together by gravity. Describe how gravity is still acting on an object that is in orbit.ĭevelop and use a model to describe the role of gravity in the motions within galaxies and the solar system.Ĭlick to view other curriculum aligned to this Performance Expectation.Articulate that to escape the Earth's gravity, engineers must design and build huge rockets.Relate the increase in velocity of an orbiting object with the object getting farther away.Explain that an orbit is the balancing of the object's velocity with the gravitational force.This requires that engineers think logically and use their math skills to forecast exactly where a planet will be located many months in the future.Īfter this activity, students should be able to: ![]() Since Earth and Mars are always orbiting in their own paths, space travel from Earth to Mars might be compared to shooting a basketball into a moving hoop while standing on a moving platform. Life in Space: The International Space Stationĭesign Devices to Help Astronauts Eat: Lunch in Outer Space!Įngineers and scientists make amazingly precise calculations so that a spacecraft's journey is timed exactly to reach the location where a planet will be at that time.
