5-PS2-1 Motion and Stability: Forces and Interactions
Students who demonstrate understanding can: Support an argument that the gravitational force exerted by the Earth is directed down.
Clarification Statement: “Down” is a local description of the direction that points toward the center of the spherical earth. Earth causes objects to have a force on them that point toward the center of the Earth, “down”. Support for arguments can be drawn from diagrams, evidence, and data that are provided.
Assessment Boundary: Mathematical representation of gravitational force is not assessed.
Crosscutting Concepts	Science & Engineering Practices	Disciplinary Core Ideas
Cause and Effect: Cause and effect relationships are routinely identified, tested, and used to explain change.	Engaging in Argument from Evidence: Engaging in argument from evidence in 3-5 builds on K-2 experiences and progresses to critiquing the scientific explanations or solutions proposed by peers by citing relevant evidence about the natural and designed world(s).	Types of Interactions: The gravitational force of Earth acting on an object near Earth’s surface pulls that object toward the planet’s center.
