MS-PS2-4 Motion and Stability: Forces and Interactions

Students who demonstrate understanding can: Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.
Clarification Statement: Examples of evidence for arguments could include data generated from simulations or digital tools; and charts displaying mass, strength of interaction, distance from the Sun, and orbital periods of objects within the solar system.
Assessment Boundary: Assessment does not include Newton’s Law of Gravitation or Kepler’s Laws.

Crosscutting Concepts

Science & Engineering Practices 

Disciplinary Core Ideas 

Systems and System Models:

  • Models can be used to represent systems and their interactions—such as inputs, processes and outputs—and energy and matter flows within systems.

Engaging in Argument from Evidence:

  • Engaging in argument from evidence in 6–8 builds from K–5 experiences and progresses to constructing a convincing argument that supports or refutes claims for either explanations or solutions about the natural and designed world. 
  • Construct and present oral and written arguments supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon or a solution to a problem. 

Types of Interactions:

  • Gravitational forces are always attractive.
  • There is a gravitational force between any two masses, but it is very small except when one or both of the objects have large mass—e.g., Earth and the sun.
