The CCC Systems and System Models is explicitly named as a unit-level crosscutting concept [E1] and is intentionally developed throughout: students build and update a class Carbon System Model and water-system model [E7][E8], construct a causal diagram that unifies the carbon and water systems to explain how fossil fuel use affects water resources [E4][E6], and use systems thinking to reason about subsystems (individuals, families, schools) nested within the larger community system [E9]. This structural evidence—named CCC, teacher-guidance prose describing system modeling, and assessment look-fors tied to system components [E3][E10]—shows the materials deliberately support this indicator across all its required components.
