Unit 2: Sprawl

Students develop ecosystem literacy at the local scale of their familiar schoolyard ecosystem. They make a land-use decision regarding the addition of an athletic field to the school grounds and investigate how land use impacts hydrology, nitrogen flux, biotic factors, social factors, and ecosystem services. They build a case for their chosen land-use decision by constructing evidence-based arguments that take impacts, ecosystem services, and social factors into account.
