    Knowledge

    Students know:
    • National and global patterns of energy consumption and production.
    • State and federal regulations for mining and reclamation of mined land, and the environmental consequences of mining.
    • Factors that influence the value of a fuel.
    • The advantages and disadvantages of the following: fossil fuels, nuclear energy, and alternative energies.
    • The uses of mineral resources as well as how they are formed.
    • The components of a cost-benefit of ratio.
    • The basic economic principle of supply and demand.
    • When evaluating solutions, it is important to consider cost, safety, reliability, and aesthetics, as well as cultural, social, and environmental impacts

    Skills

    Students are able to:
    • Evaluate the evidence for each design solutions, including societal needs for the energy or mineral resource, the cost of extracting or developing the energy reserve or mineral resource, the costs and benefits of the given design solutions, and the feasibility, costs, and benefits of recycling or reusing the mineral resource.
    • Use logical arguments, based on empirical evidence, evaluation of the design solutions, costs and benefits (both economical and environmental), and scientific ideas, to support one design over the other.

    Understanding

    Students understand that:
    • All forms of energy production and other resource extraction have associated economic, social, environmental, and geopolitical costs and risks as well as benefits. New technologies and social regulations can change the balance of these factors.
    • Scientific knowledge indicates what can happen in natural systems - not what should happen. The latter involves ethics, values, and human decisions about the use of knowledge.
    • Modern civilization depends on major technological systems. These systems are continuously modified to increase benefits while decreasing costs and risks.
    • New technologies can have significant impacts on society and the environment, including some that were not anticipated.
    • Analysis of cost-benefit ratios is an essential component to making decisions regarding the use of technology.

    Cause and Effect

    Knowledge

    Students know:
    • There is a dynamic relationship between natural resources and the biodiversity and human populations that depend on them.
    • Resource availability has guided the development of human society.

    Skills

    Students are able to:
    • Identify factors that affect the management of natural resources, including but not limited to cost of resource extraction, per capita consumption, and waste management.
    • Identify factors affecting human sustainability and biodiversity, including but not limited to agricultural efficiency, conservation, and urban planning.
    • Analyze evidence describing relationships among natural resources, human sustainability, and biodiversity.
    • Make a qualitative and/or quantitative claim regarding the relationships among management of natural resources, human sustainability, and biodiversity.

    Understanding

    Students understand that:
    • The sustainability of human societies and the biodiversity that supports them requires responsible management of natural resources.
    • Factors affecting one component of a system also have the potential to impact the other components of the system, thus it is critical to seek to understand the relationships among the components (i.e., management of natural resources, biodiversity, and human sustainability).
    • New technologies can have significant impacts on society and the environment, including some that were not anticipated.
    • Feedback (negative or positive) can stabilize or destabilize a system.

    Vocabulary

    • solid waste — biodegradable, landfill, leachate, municipal solid waste
    • agricultural efficiency — no till farming, compost, contour plowing
    • waste management — source reduction, recycling, compost
    • hazardous waste — deep well injection, surface impoundment
    • urban planning — urbanization, urban sprawl, infrastructure, heat island, land use planning, global information system (GIS)
    • resource extraction
    • per capita consumption
    • conservation
