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.

Crosscutting Concepts

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.
