 Getting a Feel for Gravity Download This Lesson (PDF, 590 KB) Topic: Grade Level: 5-8 Body: Our Solar System Mission: Science Education Standards: Physical Science: As a result of their activities in grades 5-8, all students should develop an understanding of Motions and Forces If more than one force acts on an objects along a straight lines, then the forces will reinforce and cancel one another, depending on their direction and magnitude. Unbalanced forces will cause changes in the speed or direction of an object's motion. Earth and Space Science: Earth in the Solar System Most objects in the solar system are in regular and predictable motion. Gravity is the force that keeps planets in orbit around the sun and governs the rest of the motion in the solar system. Short Description: In this kinesthetic activity, students use their own bodies to create a model of the solar system and the forces the sun and planets exert on each other and on passing objects such as spacecraft.
