# Motion and Stability: Forces and Interactions

### Students who demonstrate understanding can:

#### Performance Expectations

1. 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 and Assessment Boundary

A Peformance Expectation (PE) is what a student should be able to do to show mastery of a concept. Some PEs include a Clarification Statement and/or an Assessment Boundary. These can be found by clicking the PE for "More Info." By hovering over a PE, its corresponding pieces from the Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts will be highlighted.

### Science and Engineering Practices

#### Engaging in Argument from Evidence

Engaging in argument from evidence in 6–8 builds on 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(s).

### Connections to Nature of Science

By clicking on a specific Science and Engineering Practice, Disciplinary Core Idea, or Crosscutting Concept, you can find out more information on it. By hovering over one you can find its corresponding elements in the PEs.

## Resources & Lesson Plans

• More resources added each week!
A team of teacher curators is working to find, review, and vet online resources that support the standards. Check back often, as NSTA continues to add more targeted resources.
• This lesson plan and student worksheet have students use an online simulation to explore the relationship between gravitational pull, masses, and distance.  An optional assessment has students write one or two claim-evidence-reasoning paragraphs ...

• Students enter a weight on Earth, and view the equivalent weight on other planets, Pluto, Earth’s moon, some of Jupiter’s moons, and a few types of stars. The calculator/model is followed by a reading about the difference between mass and weight, ...
