MS-ESS2-1: Cycling of Earth's Materials

Develop a model to describe the cycling of Earth's materials and the flow of energy that drives this process. (Stability and Change)

Clarification Statement:  Emphasis is on the processes of melting, crystallization, weathering, deformation, and sedimentation, which act together to form minerals and rocks through the cycling of Earth’s materials.

Assessment Boundary: Assessment does not include the identification and naming of minerals.

The following assessments were created by science teachers hoping to better understand the NGSS. In most cases teachers went from standard to assessment in around an hour.  These are drafts and should be used accordingly. Feel free to improve these assessments or contribute to the collection. Learn more about assessment design here.
