Overview

In this lesson, students review each step of the water-treatment process used to make water potable and analyze the order in which the steps occur.

    Science (2015) Grade(s): 09-12 - Environmental Science

    SC15.ES.10

    Design solutions for protection of natural water resources (e.g., bioassessment, methods of water treatment and conservation) considering properties, uses, and pollutants (e.g., eutrophication, industrial effluents, agricultural runoffs, point and nonpoint pollution resources).*

    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.
