Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects and the distance between them.
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.

Performance Level Descriptions
Every Grade 8 Science Test question on MS-PS2-4 is written to match one of the performance level descriptions (PLDs) below.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of MS-PS2-4.
This section could be expanded upon. You can help out by adding to this section.
NGSS Dimensions
Performance expectation MS-PS2-4 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Engaging in Argument from Evidence
- Construct and present oral and written arguments supported by empirical evidence and scientific reasoning to support or refute an explanation or a model.
- PS2.B: 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.
- 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.
