    Ecosystems: Interactions, Energy, and Dynamics

Students who demonstrate understanding can:

Performance Expectations

  1. Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere. HS-LS2-5

    Clarification Statement and Assessment Boundary

A Peformance Expectation (PE) is what a student should be able to do to show mastery of a concept. Some PEs include a Clarification Statement and/or an Assessment Boundary. These can be found by clicking the PE for "More Info." By hovering over a PE, its corresponding pieces from the Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts will be highlighted.

By clicking on a specific Science and Engineering Practice, Disciplinary Core Idea, or Crosscutting Concept, you can find out more information on it. By hovering over one you can find its corresponding elements in the PEs.

  • This is one of 30 lessons from the NSTA Press book Scientific Argumentation in Biology.  The lesson engages students in an argumentation cycle in which they evaluate three alternative claims regarding where most of the matter that makes up the s ...

  • Trends in Atmospheric Carbon Dioxide is one of a series of Data Point resources from HHMI Biointeractive.  Data Points engage students in analyzing and interpreting data from primary literature in the biological sciences.  The resources pro ...

  • This is one of the many interactive labs provided by Annenberg Learner, and it is part of a course for high school teachers called, The Habitable Planet.  While the full course is designed for teachers, the labs are appropriate for use with high ...

  • This is one of 14 Virtual Labs from McDougal Littell.  In this interactive simulation, students work to answer the guiding question, “Why might Elodea plants be important in maintaining a healthy ecosystem?”, as they set up an aquari ...
