HS-ESS3-4 Evidence Statement
Earth and Space Science: Earth and Human Activity – Evidence Statement 4 HS-ESS3-4: Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.* [Clarification Statement: Examples of data on the impacts of human activities could include the quantities and types of pollutants released, changes to biomass and species diversity, or areal changes in land surface use (such as for urban development, agriculture and livestock, or…
HS-ESS3-3 Evidence Statement
Earth and Space Science: Earth and Human Activity – Evidence Statement 3 HS-ESS3-3: Create a computational simulation to illustrate the relationships among management of natural resources, the sustainability of human populations, and biodiversity. [Clarification Statement: Examples of factors that affect the management of natural resources include costs of resource extraction and waste management, per-capita consumption, and the development of new technologies. Examples of factors that affect human sustainability include agricultural…
HS-ESS3-2 Evidence Statement
Earth and Space Science: Earth and Human Activity – Evidence Statement 2 HS-ESS3-2: Evaluate competing design solutions for developing, managing, and utilizing energy and mineral resources based on cost-benefit ratios.* [Clarification Statement: Emphasis is on the conservation, recycling, and reuse of resources (such as minerals and metals) where possible, and on minimizing impacts where it is not. Examples include developing best practices for agricultural soil use, mining (for coal, tar…
HS-ESS3-1 Evidence Statement
Earth and Space Science: Earth and Human Activity – Evidence Statement 1 HS-ESS3-1: Construct an explanation based on evidence for how the availability of natural resources, occurrence of natural hazards, and changes in climate have influenced human activity. [Clarification Statement: Examples of key natural resources include access to fresh water (such as rivers, lakes, and groundwater), regions of fertile soils such as river deltas, and high concentrations of minerals and…
HS-ESS2-7 Evidence Statement
Earth and Space Science: Earth’s Systems – Evidence Statement 7 HS-ESS2-7: Construct an argument based on evidence about the simultaneous coevolution of Earth’s systems and life on Earth. [Clarification Statement: Emphasis is on the dynamic causes, effects, and feedbacks between the biosphere and Earth’s other systems, whereby geoscience factors control the evolution of life, which in turn continuously alters Earth’s surface. Examples of include how photosynthetic life altered the atmosphere…
HS-ESS2-6 Evidence Statement
Earth and Space Science: Earth’s Systems – Evidence Statement 6 HS-ESS2-6: Develop a quantitative model to describe the cycling of carbon among the hydrosphere, atmosphere, geosphere, and biosphere. [Clarification Statement: Emphasis is on modeling biogeochemical cycles that include the cycling of carbon through the ocean, atmosphere, soil, and biosphere (including humans), providing the foundation for living organisms.]
HS-ESS2-5 Evidence Statement
Earth and Space Science: Earth’s Systems – Evidence Statement 5 HS-ESS2-5: Plan and conduct an investigation of the properties of water and its effects on Earth materials and surface processes. [Clarification Statement: Emphasis is on mechanical and chemical investigations with water and a variety of solid materials to provide the evidence for connections between the hydrologic cycle and system interactions commonly known as the rock cycle. Examples of mechanical investigations…
HS-ESS2-4 Evidence Statement
Earth and Space Science: Earth’s Systems – Evidence Statement 4 HS-ESS2-4: Use a model to describe how variations in the flow of energy into and out of Earth’s systems result in changes in climate. [Clarification Statement: Examples of the causes of climate change differ by timescale, over 1-10 years: large volcanic eruption, ocean circulation; 10-100s of years: changes in human activity, ocean circulation, solar output; 10-100s of thousands of years:…
HS-ESS2-3 Evidence Statement
Earth and Space Science: Earth’s Systems – Evidence Statement 3 HS-ESS2-3: Develop a model based on evidence of Earth’s interior to describe the cycling of matter by thermal convection. [ClarificationStatement: Emphasis is on both a one-dimensional model of Earth,with radial layers determined by density, and a three-dimensional model,which is controlled by mantle convection and the resulting plate tectonics. Examples of evidence include maps of Earth’s three-dimensional structure obtained from seismic…
HS-ESS2-2 Evidence Statement
Earth and Space Science: Earth’s Systems – Evidence Statement 2 HS-ESS2-2: Analyze geoscience data to make the claim that one change to Earth’s surface can create feedbacks that cause changes to other Earth systems. [Clarification Statement: Examples should include climate feedbacks, such as how an increase in greenhouse gases causes a rise in global temperatures that melts glacial ice, which reduces the amount of sunlight reflected from Earth’s surface, increasing…
