2.1.4: Some changes in the earth can be described as the ?rock cycle.? Rocks at the earth?s surface weather, forming sediments that are buried, then compacted, heated, and often re-crystallized into new rock. Eventually, those new rocks may be brought to the surface by the forces that drive plate motions, and the rock cycle continues.
2.2.1: Water, which covers the majority of the earth?s surface, circulates through the crust, oceans, and atmosphere in what is known as the ?water cycle.? Water evaporates from the earth?s surface, rises and cools as it rises to higher elevations, condenses as rain or snow, and falls to the surface where it collects in lakes, oceans, soil and in soil and rocks underground.
2.2.3: Natural and human forces can contribute to contamination of surface water and groundwater.
2.3.1: The earth processes we see today including erosion, movement of tectonic plates, and changes in atmospheric composition are similar to those that occurred in the past.
2.3.3: Fossils provide important evidence of how life and environmental conditions have changed.
2.5.1: The earth is the third planet from the sun in a system that includes the moon, the sun, seven other planets and their moons, and smaller objects, such as asteroids and comets. The sun, an average star, is the central and largest body in the solar system.
2.5.2: Gravity is the force that keeps planets in orbit around the sun and governs the rest of the motion in the solar system. Gravity alone holds us to the earth?s surface and explains the phenomena of the tides.
2.5.3: The sun is the major source of energy for phenomena on the earth?s surface, such as growth of plants, winds, ocean currents, and the water cycle. Seasons result from variations in the amount of the sun?s energy hitting the surface, due to the tilt of the earth?s rotation on its axis and the length of the day.
2.5.4: Most objects in the solar system are in regular and predictable motion. Those motions explain such phenomena as the day, the year, phases of the moon, and eclipses.
3.2.1: Energy is a property of many substances and is associated with heat, light, electricity, mechanical motion, sound, nuclei, and the nature of a chemical. Energy is transferred in many ways.
3.2.2: Heat moves in predictable ways, flowing from warmer objects to cooler ones, until both reach the same temperature.
3.2.3: Light interacts with matter by transmission (including refraction), absorption, or scattering (including reflection). To see an object, light from that object- emitted by or scattered from it- must enter the eye.
3.2.6: The sun is a major source of energy for changes on the earth?s surface. The sun loses energy by emitting light. A tiny fraction of that light reaches the earth, transferring energy form the sun to the earth. The sun?s energy arrives as light with a range of wavelengths, consisting of visible light, infrared, and ultraviolet radiation.
3.3.1: The motion of an object can be described by its position, direction of motion, and speed. That motion can be measured and represented on a graph.
4.1.1: Living systems at all levels of organization demonstrate the complementary nature of structure and function. Important levels of organization for structure and function include cells, organs, tissues, organ systems, whole organisms, and ecosystems.
4.1.2: All organisms are composed of cells. Most organisms are single cells; other organisms, including humans are multi-cellular.
4.2.1: Every organism requires a set of instructions for specifying its traits. Heredity is the passage of these instructions from one generation to another.
4.2.2: Hereditary information is contained in genes, located in the chromosomes of each cell. Each gene carries a single unit of information. An inherited trait of an individual can be determined by one or by many genes, and a single gene can influence more than one trait. A human cell contains many thousands of different genes.
4.3.1: Living systems at all levels of organization demonstrate the complementary nature of structure and function. Important levels of organization for structure and function include cells, organs, tissues, organ systems, whole organisms, and ecosystems. Organisms are classified according to common characteristics.
4.4b.3: Behavior is one kind of response an organism can make to an internal or environmental stimulus. A behavioral response requires coordination and communication on many levels, including cells, organ systems, and whole organisms. Behavioral response is a set of actions determined in part by heredity and in part from experience.
4.4b.6: For ecosystems, the major source of energy is sunlight. Energy entering ecosystems as sunlight is transferred by producers into chemical energy through photosynthesis. That energy then passes from organism to organism in food webs.
4.5.2: The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. Given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid rates. Lack of resources and other factors, such as predation and climate, limit the growth of populations in specific niches in the ecosystem.
4.6.1: The human organism has systems for digestion, respiration, reproduction, circulation, excretion, movement, control, and coordination, and for protection from disease. These systems interact with one another.
