Title Gravity and Orbits
Description This activity was developed for 5th and 6th grade classrooms, though can probably be used in a variety of settings. Students will be able to: • Draw motion of planets, Moons and satellites. • Draw diagrams to show how gravity is the force that controls the motion of our solar system. • Identify the variables that affect the strength of the gravity. • Predict how motion would change if gravity was stronger or weaker. The Student Activity includes pre- and post-labs, but these can be excluded.
