Support an argument that the gravitational force exerted by Earth on objects is directed down. 5-PS2-1
Clarification Statement: “Down” is a local description of the direction that points toward the center of the spherical Earth.
Assessment Boundary: Assessment does not include mathematical representation of gravitational force.
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).
Support an argument with evidence, data, or a model. (5-PS2-1)
PS2.B: Types of Interactions
The gravitational force of Earth acting on an object near Earth’s surface pulls that object toward the planet’s center. (5-PS2-1)
Cause and Effect
Cause and effect relationships are routinely identified and used to explain change. (5-PS2-1)
