Middle School Performance Expectations MS-LS16. MS-LS17. MS-LS2-3 MS-ESS21. Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms, including how chemical reactions form new molecules to support growth and/or release energy, as well as cycling between living and nonliving parts of an ecosystem. [Clarification Statement: Emphasis is on tracing movement of matter and flow of energy.] Examples we could use. . . MS-LS21. MS-LS24. Analyze and interpret data to provide evidence for the effects of resource availability, and other physical, or biological components of an ecosystem, on organisms and populations of organisms in an ecosystem. [Clarification Statement: Emphasis is on cause and effect relationships between resources and growth of individual organisms and the numbers of organisms in ecosystems during periods of abundant and scarce resources.] Examples we could use. . . MS-LS22. Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.[Clarification Statement: Emphasis is on predicting consistent patterns of interactions in different ecosystems in terms of the relationships among and between organisms and abiotic components of ecosystems. Examples of types of interactions could include competitive, predatory, and mutually beneficial.] Examples we could use. . . MS-LS25. MS-ESS33. Evaluate competing design solutions for maintaining biodiversity and ecosystem services and apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.* [Clarification Statement: Examples of ecosystem services could include water purification, nutrient recycling, and prevention of soil erosion. Examples of design solution constraints could include scientific, economic, and social considerations.] Examples we could use. . .
