SCIENCE CURRICULUM Earth Science 2009 Revision Team Jenny Groh Central Office David Wade Stuarts Draft High School Chase Hughes Stuarts Draft High School Rob Killmon Fort Defiance High School Augusta County, Virginia Rob Maxwell Buffalo Gap High School Dane Barr Wilson Memorial High School Philosophy for Teaching Science in Augusta County: All of us have a stake, as individuals and as a society, in scientific literacy. An understanding of science makes it possible for everyone to share in the richness and excitement of comprehending the natural world. Scientific literacy enables people to use scientific principles and processes in making personal decisions and to participate in discussions of scientific issues that affect society. A sound grounding in science strengthens many of the skills that people use every day, like solving problems creatively, thinking critically, working cooperatively in teams, using technology effectively, and valuing life-long learning. And the economic productivity of our society is tightly linked to the scientific and technological skills of our work force. Acknowledgements: National Science Education Standards, 1998.

Minerals may be identified by their physical properties such as hardness, color, luster, and streak. Most rocks are made of one or more minerals. Some major rock-forming minerals are quartz, feldspar, calcite, and mica. Ore minerals include pyrite, magnetite, hematite, galena, halite, graphite, and sulfur. The major elements found in the Earth’s crust are oxygen, silicon, aluminum, and iron. The most abundant group of minerals is the silicates, which contain silicon and oxygen. Igneous rock forms from molten rock that cools and hardens either below or on the Earth’s surface.

Sedimentary rocks form from rock fragments or organic matter bound together, or are formed by chemical precipitation. Metamorphic rocks form by the effects of heat, pressure, or chemical action on other rocks. Sedimentary rocks are clastic or nonclastic. Clastic sedimentary rocks are made up of fragments of other rocks and include sandstone, conglomerate, and shale. Non-clastic sedimentary rocks include limestone and gypsum. Metamorphic rocks can be foliated or unfoliated. Foliated metamorphic rocks have fine layers and include slate, schist, and gneiss. Unfoliated metamorphic rocks have few or no layers and include marble and quartzite. Interpret the rock cycle diagram. Classify the following rock types as igneous, metamorphic, or sedimentary: pumice, obsidian, basalt, granite, sandstone, conglomerate, shale, limestone, gypsum, slate, schist, gneiss, marble, and quartzite. Renewable resources can be replaced by nature at a rate close to the rate at which they are used. Renewable resources include vegetation, sunlight, and surface water. Nonrenewable resources are renewed very slowly or not at all. Nonrenewable resources include coal, oil, and minerals. Fossil fuels are nonrenewable and may cause pollution, but they are relatively cheap and easy to use. In Virginia, major rock and mineral resources include coal for energy, gravel and crushed stone for road construction, Alternative Energy Poster/Activity and limestone for making concrete.

The Coastal Plain is a flat area underlain by young, unconsolidated sediments. These layers of sediment were produced by erosion of the Appalachian Mountains and then deposited on the Coastal Plain. The Piedmont is an area of rolling hills underlain by mostly ancient igneous and metamorphic rocks. The igneous rocks are the roots of volcanoes formed during an ancient episode of subduction that occurred before the formation of the Appalachian Mountains. The Blue Ridge is a high ridge separating the Piedmont from the Valley and Ridge Province. The billion-year old igneous and metamorphic rocks of the Blue Ridge are the oldest in the state. Some metamorphism of these rocks occurred during the formation of the Appalachian Mountains. The Valley and Ridge province is an area with long parallel ridges and valleys underlain by ancient folded and faulted sedimentary rocks. The folding and faulting of the sedimentary rocks occurred during a collision between Africa and North America. The collision, which occurred in the late Paleozoic, produced the Appalachian Mountains. The Appalachian Plateau has rugged irregular topography and is underlain by ancient, flat-lying sedimentary rocks. The area is actually a series of plateaus separated by faults. Most of Virginia’s coal resources are found in the plateau province.

Chapter 9 A View of Earth’s Past ES. 10 a,b,c,d A fossil is the remains, impressions, or other evidence of the former existence of life preserved in rock. Some ways in which fossils can be preserved are molds, casts, and original bone or shell. Almost all fossils are found in sedimentary rocks. In Virginia, fossils are found mainly in the Coastal Plain, Valley and Ridge, and Appalachian Plateau provinces. Most Virginia fossils are of marine organisms. This indicates that large areas of the state have been periodically covered by seawater. Relative time places events in a sequence without assigning any numerical ages. Fossils, superposition, and crosscutting relations are used to determine the relative ages of rocks. Absolute time places a numerical age on an event. Radioactive decay is used to determine the absolute age of rocks. Interpret a simple geologic history diagram using superposition and cross-cutting relations. Paleozoic, Mesozoic, and Cenozoic fossils are found in Virginia. Describe how life has changed and become more complex over geologic time.

Erosion is the process by which earth materials are transported by moving water, ice, or wind. Deposition is the process by which Earth materials carried by wind, water, or ice settle out and are deposited. Weathering accelerates erosion and thus increases the rate of deposition. The potential for erosion is greatest in areas of high relief. The potential for deposition is greatest in areas of low relief, especially standing water, and particularly the ocean.

Estuaries, like the Chesapeake Bay, are areas where fresh and salt water mix, producing variations in salinity and high biological activity. The stored heat in the ocean drives much of the Earth’s weather. The stored heat in the ocean causes climate near the ocean to be milder than climate in the interior of continents. Sonar Lab Some ocean currents are convection currents The tides are the daily, periodic rise and fall of water level caused by the gravitational pull of the sun and moon. Most waves on the ocean surface are generated by wind.

Topic: Atmospheric Forces (Chapters 22-25) Major Earth Curriculum Science Area SOL Chapter 22 The Atmosphere ES.12 a,b,c,d,e Essential Knowledge and Skills Convection is a current that is set up when hot, less dense material rises, cools, becomes denser, and sinks. Convection is the major mechanism of energy transfer in the oceans, atmosphere, and Earth’s interior. Convection in the atmosphere is a major cause of weather. The early atmosphere contained little oxygen and more carbon dioxide than the modern atmosphere. Early photosynthetic life (algae and blue-green algae) generated oxygen and consumed carbon dioxide. It was only after early photosynthetic life generated oxygen that animal life became possible. The Earth’s atmosphere is 21 percent oxygen, 78 percent nitrogen, and 1 percent trace gases. Human activities have increased the carbon dioxide content of the atmosphere. Man-made chemicals have decreased the ozone concentration in the upper atmosphere. Volcanic activity and meteorite impacts can inject large quantities of dust and gases into the atmosphere. The ability of the Earth’s atmosphere to absorb and retain heat is affected by the presence of gases like water vapor and carbon dioxide.

There are essentially two types of planets in our solar system. Water occurs on Earth as a solid (ice), a liquid, or a gas (water vapor) due to Earth’s position in the solar system. The four inner (terrestrial) planets consist mostly of solid rock. Four of the outer planets are gas giants, consisting of thick outer layers of gaseous materials, perhaps with a small rocky core. The Earth is the third planet from the sun. The fifth outer planet Pluto has an unknown composition, and appears solid. The atmosphere of Venus is mostly carbon dioxide and very dense. The Martian atmosphere is very thin and mostly carbon dioxide. The moon revolves around Earth, creating the moon phases and eclipses. Solar eclipses occur when the moon blocks sunlight from Earth’s surface, while lunar eclipses whrn earth blocks sunlight from reaching the moon’s surface. The tides are the daily, periodic rise and fall of water level caused by the gravitational pull of sun and moon. Moons are natural satellites of planets that vary widely in composition. Comets orbit the sun and consist mostly of frozen gases. Asteroids are rocky or metallic iron objects ranging in size from millimeters to kilometers. They are the source of most meteorites. The sun consists largely of hydrogen gas. Its energy comes from nuclear fusion of hydrogen to helium.

Movies: Constellations The Universe (BBC) Stellar Evolution Poster The Big Bang Theory states that the universe began as a dense sphere that expanded and eventually condensed into galaxies. The solar nebular theory explains that the planets formed through condensing of the solar nebula. Stars form by condensation of interstellar gas. The Hertzsprung-Russell diagram illustrates the relationship between the absolute magnitude and the surface temperature of stars. As stars evolve, there position on the H-R diagram moves. Galaxies are collections of large numbers (billions) of stars. The sun is in the Milky Way galaxy. The solar system is located in the Milky Way Galaxy. The basic types of galaxies are spiral, elliptical, and irregular. A light-year is the distance light travels in one year and is the most commonly used measurement for distance in astronomy. Much of our information about our galaxy and the universe comes from ground-based observations.
