      Constructing Explanations and Designing SolutionsMS.IRE.SEP.1

      1. a

        Construct an explanation that includes qualitative or quantitative relationships between variables that predict phenomena. (MS-LS2-2)MS.IRE.SEP.1a

      Engaging in Argument from EvidenceMS.IRE.SEP.2

      1. a

        Similarly, predatory interactions may reduce the number of organisms or eliminate whole populations of organisms. Mutually beneficial interactions, in contrast, may become so interdependent that each organism requires the other for survival. Although the species involved in these competitive, predatory, and mutually beneficial interactions vary across ecosystems, the patterns of interactions of organisms with their environments, both living and nonliving, are shared.

        (NYSED) Biodiversity describes the variety of species found in Earth’s ecosystems. The completeness or integrity of an ecosystem’s biodiversity is often used as a measure of its health. (MS-LS2-5)MS.IRE.DCI.LS2.C.1

      LS4.D: Biodiversity and HumansMS.IRE.DCI.LS4.D

      1. a

        Changes in biodiversity can influence humans’ resources, such as food, energy, and medicines, as well as ecosystem services that humans rely on—for example, water purification and recycling. (secondary to MS-LS2-5)MS.IRE.DCI.LS4.D.1

        (NYSED) Humans impact biodiversity both positively and negatively. (secondary to MS-LS2-5)MS.IRE.DCI.LS4.D.2

    Crosscutting ConceptsMS.IRE.CC

    1. 1

      PatternsMS.IRE.CC.1

      1. a

        Patterns can be used to identify cause and effect relationships. (MSLS2-2)MS.IRE.CC.1a

      Stability and ChangeMS.IRE.CC.2

      1. a

        Small changes in one part of a system might cause large changes in another part. (MS-LS2-5)MS.IRE.CC.2a

    3. 3

      Influence of Science, Engineering, and Technology on Society and the Natural WorldMS.IRE.CC.3

      1. a

        The use of technologies and any limitations on their use are driven by individual or societal needs, desires, and values; by the findings of scientific research; and by differences in such factors as climate, natural resources, and economic conditions. Thus technology use varies from region to region and over time. (MS-LS2-5)MS.IRE.CC.3a

      Science Addersses Questions About the Natural and Material WorldMS.IRE.CC.4

      1. a

        Scientific knowledge can describe the consequences of actions but does not necessarily prescribe the decisions that society takes. (MS-LS2-5)MS.IRE.CC.4a
