Earth and Space Sciences

Students demonstrate an understanding about how Earth systems and processes interact in the geosphere resulting in the habitability of Earth. This includes demonstrating an understanding of the composition of the universe, the Solar System and Earth. In addition, it includes understanding the properties and the interconnected nature of Earth’s systems, processes that shape the Earth and Earth’s history. Students also demonstrate an understanding of how the concepts and principles of energy, matter, motion and forces explain Earth systems, the Solar System, and the Universe. Finally, they grasp an understanding of the historical perspectives, scientific approaches and emerging scientific issues associated with the Earth and space sciences.

Benchmark A. Explain how technology can be used to gather evidence and increase our understanding of the universe.
The Universe
1. Describe how the early Earth was different from the planet we live on today, and explain the formation of the Sun, Earth and the rest of the Solar System from a nebular cloud of dust and gas approximately 4.6 billion years ago.
Benchmark B. Describe how Earth is made up of a series of interconnected systems and how a change in one system affects other systems.
Earth Systems
2. Analyze how the regular and predictable motions of Earth, Sun and Moon explain phenomena on Earth (e.g., seasons, tides, eclipses and phases of the Moon).
3. Explain heat and energy transfers in and out of the atmosphere and its involvment in weather and climate (radiation, conduction, convection and advection).
4. Explain the impact of oceanic and atmospheric currents on weather and climate.
5. Use appropriate data to analyze and predict upcoming trends in global weather patterns (e.g., el Niño and la Niña, melting glaciers and icecaps, changes in ocean surface temperatures).
6. Explain how interactions among Earth’s lithosphere, hydrosphere, atmosphere and biosphere have resulted in the ongoing changes of the Earth system.
7. Describe the effects of particulates and gases in the atmosphere including those originating from volcanic activity.
8. Describe the normal adjustments of Earth, which may be hazardous for humans. Recognize that humans live at the interface between the atmosphere driven by solar energy and the upper mantle where convection creates changes in Earth's solid crust. Realize that as societies have grown, become stable and come to value aspects of the environment, vulnerability to natural processes of change has increased.
10. Interpret weather maps and their symbols to predict changing weather conditions worldwide (e.g., monsoons, hurricanes and cyclones).
Benchmark C. Explain that humans are an integral part of the Earth's system and the choices humans make today impact natural systems in the future.
Earth Systems
9. Explain the effects of biomass and human activity on climate (e.g., climatic change, global warming).
11. Analyze how materials from human societies (e.g., radioactive waste, air pollution) affect both physical and chemical cycles of Earth.
12. Explain ways in which humans have had a major effect on other species (e.g., the influence of humans on other organisms occurs through land use, which decreases space available to other species and pollution, which changes the chemical composition of air, soil and water).
13. Explain how human behavior affects the basic processes of natural ecosystems and the quality of the atmosphere, hydrosphere and lithosphere.
14. Conclude that Earth has finite resources and explain that humans deplete some resources faster than they can be renewed.
Benchmark D. Summarize the historical development of scientific theories and ideas and describe emerging issues in the study of Earth and space sciences.
 Historical Perspectives and Scientific Revolutions
15. Use historical examples to show how new ideas are limited by the context in which they are conceived; are often rejected by the social establishment; sometimes spring from unexpected findings; and usually grow slowly, through contributions from many different investigators (e.g., global warming, heliocentric theory, theory of continental drift).
16. Describe advances in earth and space science that have important long-lasting effects on science and society (e.g., global warming, heliocentric theory, plate tectonics theory).
