NEXT GENERATION SCIENCE STANDARDS (NGSS)

The Snails and Ecosystems teaching resources support students in meeting the following middle school NGSS Performance Expectations:

Life Science

MS-LS2

Ecosystems: Interactions, Energy, and Dynamics
  • MS-LS2-2Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.
  • MS-LS2-3Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
  • MS-LS2-4Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
  • MS-LS2-5Evaluate competing design solutions for maintaining biodiversity and ecosystem services.
Earth Science

MS-ESS3

Earth and Human Activity
  • MS-ESS3-4Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth's systems.
