Carbon TIME: Human Energy Systems Unit

Download All Human Energy Systems Unit Materials

2018-19 Field Test Version

The Human Energy Systems Unit builds on student learning in Systems and Scale, Animals, Plants, Decomposers, and Ecosystems Units about organic and inorganic materials, how all systems exist at multiple scales, and transformation of materials and energy during chemical change. In the Human Energy Systems Unit, students focus on how three carbon–transforming processes (photosynthesis, cellular respiration, and combustion) work in global systems to balance carbon pools and fluxes. Overall, this Unit has four important goals for student learning:

  1. Using knowledge of representation, generalizability, short-term variation, and long-term trends to interpret large-scale data sets related to climate change;
  2. Relating changes in carbon pools to the balance of movement of carbon between these pools;
  3. Relating carbon emissions to energy use;
  4. Relating local systems, actions, and choices to global effects and future outcomes.
