Introduction


Major Themes for the Unit

  • Scientific themes: Ecological Interactions, Climate Change, Nutrient Cycling, Energy Flow, Biodiversity
  • Scientific practice: modeling, argumentation
  • SSI: Climate change and its effect on ecosystems

Driving Question: How might climate change affect the complex interactions in local ecosystems?

Concepts needed to explore the driving question

  • Science concepts
    • Carbon Cycling
    • Photosynthesis
    • Relationship Between Photosynthesis and Cellular Respiration
    • Ecological Interactions
    • Energy Flow
  • What social ideas and concerns influence negotiation of the issue?
    • Economics
    • Politics
    • Energy Production and Consumption
    • Alternative Energy Sources

Unit-level performance expectations

  • Use an ecosystem model to make predictions regarding the stability/change of populations within a particular ecosystem in response to climatic changes. Engage in argumentation about the relative stability/change of an ecosystem (NGSS HS-LS2-6).
  • Develop and use multiple models, some of which include mathematical representations, to explain the cycling of matter and flow of energy among organisms in an ecosystem (NGSS HS-LS2-2, HS-LS2-4). 
  • Obtain, evaluate and communicate information about a specific climate change impact. Engage in argumentation regarding appropriate responses to this situation (NGSS HS-LS2-7).
  • Develop a qualitative model of the inputs and outputs of photosynthesis that accounts for/predicts impacts of climatic changes (NGSS HS-LS1-5).
  • Develop a qualitative model of the inputs and outputs of cellular respiration that accounts for the cycling of matter and transfer of energy (NGSS HS-LS1-7, HS-LS2-5).
  • Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere (NGSS HS-LS2-5).
