Knowledge

Students know:
  • The types and uses of natural water resources.
  • Structure of a watershed and its functions through time.
  • Strategies for water management and conservation.
  • Sources of freshwater and ocean water pollution.
  • Legislation that addresses the protection of natural water resources.
  • Methods of water treatment.

Skills

Students are able to:
  • Identify sources of point and nonpoint contamination.
  • Identify natural water resources and factors that affect them.
  • Obtain, evaluate, and communicate information on the properties, uses, and pollutants of natural water resources.
  • Analyze and interpret data to evaluate water resources and EPA standard limits.
  • Make a quantitative or qualitative claim regarding the relationship between a natural water resource and a factor that negatively impacts its use/function.
  • Investigate and assess the health of natural water resources.
  • Design or refine a solution to protect natural water resources, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and trade-off considerations.
  • Identify costs, safety, aesthetics, reliability, cultural and environmental impacts of proposed solution.

Understanding

Students understand that:
  • Resource availability has guided the development of human society.
  • Scientists and engineers can develop technologies that produce less pollution and waste and that preclude ecosystem degradation.
  • When evaluating solutions, cost, safety, reliability, and aesthetics must be taken into consideration, as well as any social, cultural, and environmental impacts.
  • The sustainability of human societies and the biodiversity that supports them requires responsible management of natural resources.
