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…
HS-ESS2-1 Evidence Statement
Earth and Space Science: Earth’s Systems – Evidence Statement 1 HS-ESS2-1: Develop a model to illustrate how Earth’s internal and surface processes operate at different spatial and temporal scales to form continental and ocean-floor features. [Clarification Statement: Emphasis is on how the appearance of land features (such as mountains, valleys, and plateaus) and sea-floor features (such as trenches, ridges, and seamounts) are a result of both constructive forces (such as…
HS-ESS1-6 Evidence Statement
Earth and Space Science: Earth’s Place in the Universe – Evidence Statement 6 HS-ESS1-6: Apply scientific reasoning and evidence from ancient Earth materials, meteorites, and other planetary surfaces to construct an account of Earth’s formation and early history. [Clarification Statement: Emphasis is on using available evidence within the solar system to reconstruct the early history of Earth, which formed along with the rest of the solar system 4.6 billion years…
HS-ESS1-5 Evidence Statement
Earth and Space Science: Earth’s Place in the Universe – Evidence Statement 5 HS-ESS1-5: Evaluate evidence of the past and current movements of continental and oceanic crust and the theory of plate tectonics to explain the ages of crustal rocks. [Clarification Statement: Emphasis is on the ability of plate tectonics to explain the ages of crustal rocks. Examples include evidence of the ages oceanic crust increasing with distance from mid-ocean…
HS-ESS1-4 Evidence Statement
Earth and Space Science: Earth’s Place in the Universe – Evidence Statement 4 HS-ESS1-4: Use mathematical or computational representations to predict the motion of orbiting objects in the solar system. [Clarification Statement: Emphasis is on Newtonian gravitational laws governing orbital motions, which apply to human-made satellites as well as planets and moons.] [Assessment Boundary: Mathematical representations for the gravitational attraction of bodies and Kepler’s Laws of orbital motions should not…
