   4. Ms. Mihalek's unit goals
3. LS2.C: Ecosystem Dynamics, Functioning, and Resilience
   1. SWBAT list factors that can impact an ecosystem, both naturally occurring and those influenced by anthropological effects.
      1. HS-LS2-2.Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales
         1. Decline of one species can affect entire ecosystem
      2. HS-LS2-7. Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.
         1. Human activity has an impact on ecosystems
4. LS2.A: Interdependent Relationships in Ecosystems
   1. SWBAT analyze and graph a predator- prey relationship in their ecosystem
      1. HS-LS2-1.Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
         1. Analyzing data, population predictions can be made.
         2. As prey decrease predators decrease.
         3. As predators decrease prey increases.
   2. SWBAT describe the different cycle of a nutrient (carbon & water) as it moves through an ecosystem.
      1. 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.
         1. Photosynthesis uses carbon.
         2. Cellular respiration releases carbon
      2. HS-LS2-4.Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
         1. Carbon and water cycles through the ecosystem
      3. HS-LS2-3.Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
         1. Decomposers break down dead organisms
5. LS2.B: Cycles of Matter and Energy Transfer in Ecosystems
   1. SWBAT describe how energy flows through ecosystems (autotrophs and heterotrophs) and provide specific description of how energy flows through your ecosystem
      1. Energy is passed from prey to predator.
      2. Energy decreases as you move up the trophic levels.
      3. Energy is given off by the sun.
      4. Sun is the ultimate source of energy
