Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.
Clarification statement: Emphasis for the model is on gravity as the force that holds together the solar system and Milky Way galaxy and controls orbital motions within them. Examples of models could include physical models (such as a model of the solar system scaled using various measures or computer visualizations of elliptical orbits) or conceptual models (such as mathematical proportions relative to the size of familiar objects such as students’ school or state).
Assessment boundary: Assessment does not include Kepler’s Laws of orbital motion or the apparent retrograde motion of the planets as viewed from Earth.
Grade 8 Science Test Questions
Released New York State Grade 8 science test questions that assess MS-ESS1-2 are listed here by test and question cluster. Each link opens the question with its answer key.
Performance Level Descriptions
Every Grade 8 Science Test question on MS-ESS1-2 is written to match one of the performance level descriptions (PLDs) below.
Level 1: Given a model, identify the force that controls motions within galaxies and/or the solar system.
Level 2: Given a model, describe the role of gravity in the motions within galaxies and/or the solar system.
Level 3: Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.
Level 4: Develop and use a model to describe the role of gravity, both qualitatively and quantitatively, in the formation and motions within galaxies and the solar system.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of MS-ESS1-2.
This section could be expanded upon. You can help out by adding to this section.
NGSS Dimensions
Performance expectation MS-ESS1-2 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
Science and Engineering Practices
- Developing and Using Models
- Develop and use a model to describe phenomena.
Disciplinary Core Ideas
- ESS1.A: The Universe and Its Stars
- Earth and its solar system are part of the Milky Way galaxy, which is one of many galaxies in the universe.
- ESS1.B: Earth and the Solar System
- (NYSED) The solar system consists of the Sun and a collection of objects, including planets, their moons, comets, and asteroids that are held in orbit around the Sun by its gravitational pull on them.
- The solar system appears to have formed from a disk of dust and gas, drawn together by gravity.
Crosscutting Concepts
- 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.
