MS-ESS2-4 Earth’s Systems
|
Students who demonstrate understanding can: Develop a model to describe the cycling of water through Earth’s systems driven by energy from the sun and the force of gravity. |
Clarification Statement: Emphasis is on the ways water changes its state as it moves through the multiple pathways of the hydrologic cycle. Examples of models can be conceptual or physical.
|
Assessment Boundary: A quantitative understanding of the latent heats of vaporization and fusion is not assessed.

Science & Engineering Practices
|
Disciplinary Core Ideas
|
Energy and Matter:
- Within a natural or designed system, the transfer of energy drives the motion and/or cycling of matter.
|
Developing and Using Models:
- Modeling in 6–8 builds on K–5 experiences and progresses to developing, using, and revising models to describe, test, and predict more abstract phenomena and design systems.
- Develop a model to describe unobservable mechanisms.
|
The Roles of Water in Earth’s Surface Processes:
- Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land.
- Global movements of water and its changes in form are propelled by sunlight and gravity.
