MS-LS2-3: Matter Cycling and Energy Flow in Ecosystems
Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
Clarification Statement: Emphasis is on describing the conservation of matter and flow of energy into and out of various ecosystems, and on defining the boundaries of the system.
Assessment Boundary: Assessment does not include the use of chemical reactions to describe the processes.
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.
Living (biotic) parts
Nonliving (abiotic) parts (e.g. water, minerals, air)
