HS-EVS1-1 (Resources and Resource Management)
5
Analyze and interpret data to identify the factors that affect sustainable development and natural resource management in Louisiana.
6
Clarification Statement
7
Evidence of Louisiana’s natural resource wealth is found in understanding functions and values of varied ecosystems and environments, supply of non-renewable mining products and profitable agricultural commodities. Examples of key natural resources include state waterways (such as rivers, lakes, and bayous) and the aquatic life found in them, regions of agriculture (pine forests, sugarcane and rice fields) and high concentrations of minerals and fossil fuels on and off shore. Factors to consider in reviewing the management of natural resources include a review of historical practices, costs of resource extraction and waste management, consumption of natural resources, ongoing research and the advancements in technology.

Analyzing and interpreting data:
Analyzing data in 9–12 builds on K–8 experiences and progresses to introducing more detailed statistical analysis, the comparison of data sets for consistency, and the use of models to generate and analyze data.

• Analyze data using tools, technologies, and/ or models (e.g., computational, mathematical) in order to make valid and reliable scientific claims or determine an optimal design solution.
LOUISIANA’S NATURAL RESOURCES
Ecosystem capital can be characterized as goods (removable products) and services such as the functions and values of wetlands. (HS.EVS1A.a)

STABILITY AND CHANGE
Change and rates of change can be quantified and modeled over very short or very long periods of time. Some system changes are irreversible.

Obtain, evaluate and communicate information on the effectiveness of management or conservation practices for one of Louisiana’s natural resources with respect to common considerations such as social, economic, technological, and influencing political factors over the past 50 years.

Clarification Statement

The rate of land loss and habitat conversion from a variety of forces results in stresses and constraints that influence decisions and carry consequences that affect quality of life and have a bearing on sustainability. Increases in commercial and recreational uses may result in the need for environmental policies and call for changes in long established practices. Community efforts to address changes to secure growth while preserving the resources depend on education and collaboration between groups. Examples may include groundwater conservation, erosion/ flood control, forestry stewardship, game and wildlife, commercial fishing, oil and gas industry, dredging, or regulatory factors.

Obtaining, evaluating, and communicating information:
Obtaining, evaluating, and communicating information in 9–12 builds on K–8 experiences and progresses to evaluating the validity and reliability of the claims, methods, and designs.

• Compare, integrate and evaluate sources of information presented in different media or formats (e.g., visually, quantitatively) as well as in words in order to address a scientific question or solve a problem.

• Gather, read, and evaluate scientific and/ or technical information from multiple authoritative sources, assessing the evidence and usefulness of each source.
RESOURCE MANAGEMENT FOR LOUISIANA
Population growth along with cultural and economic factors impact resource availability, distribution and use. (HS.EVS1B.a)

RESOURCE MANAGEMENT FOR LOUISIANA
Some changes to our natural environment such as the building of levees and hydrological modification have provided for economic and social development but have resulted in unintended negative impacts. (HS.EVS1.B.b)

SYSTEMS AND SYSTEM MODELS
When investigating or describing a system, the boundaries and initial conditions of the system need to be defined and their inputs and outputs analyzed and described using models.

HS-EVS1-3 (Resources and Resource Management)
76
Analyze and interpret data about the consequences of environmental decisions to determine the risk-benefit values of actions and practices implemented for selected issues.

Clarification Statement
79
Examples could be taken from system interactions: (1) loss of ground vegetation causing an increase in water runoff and soil erosion. (2) dammed rivers increasing ground-water recharge, decreasing sediment transport, and increasing coastal erosion. (3) loss of wetlands reducing storm protection buffer zones allowing further wetland reduction. (4) hydrological modification such as levees providing protection to infrastructure at a cost to ecosystems.

Analyzing and interpreting data:
Analyzing data in 9–12 builds on K–8 experiences and progresses to introducing more detailed statistical analysis, the comparison of data sets for consistency, and the use of models to generate and analyze data.

• Analyze data to identify design features or characteristics of the components of a proposed process or system to optimize it relative to criteria for success.

CAUSE AND EFFECT
Cause and effect relationships can be suggested and predicted for complex natural and human-designed systems by examining what is known about smaller scale mechanisms within the system.
