• Physical Science
  • Interactions of energy and matter
    • Electromagnetic waves include radio waves (the longest wavelength), microwaves, infrared radiation (radiant heat), visible light, ultraviolet radiation, x-rays, and gamma rays. (9-12)

• Earth Science
  • Properties of earth materials
    • Earth materials are solid rocks and soils, water, and the gases of the atmosphere.
  • Objects in the sky
    • The sun, moon, stars, clouds, birds, and airplanes all have properties, locations, and movements that can be observed and described.
    • The sun provides the light and heat necessary to maintain the temperature of the earth.
  • Changes in earth and sky
    • Objects in the sky have patterns of movement.
    • The sun appears to move across the sky in the same way every day, but its path changes slowly over the seasons.
    • The moon moves across the sky on a daily basis much like the sun.
    • The observable shape of the moon changes from day to day in a cycle that lasts about a month.
  • Structure of the earth system
    • 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." (5-8)
    • Water evaporates from the earth's surface, rises and cools as it moves to higher elevations, condenses as rain or snow, and falls to the surface where it collects in lakes, oceans, soil, and in rocks underground. (5-8)
    • Water is a solvent. As it passes through the water cycle it dissolves minerals and gases and carries them to the oceans. (5-8)
    • The atmosphere is a mixture of nitrogen, oxygen, and trace gases that include water vapor. (5-8)
    • Oceans have a major effect on climate, because water in the oceans holds a large amount of heat. (5-8)
    • Living organisms have played many roles in the earth system, including affecting the composition of the atmosphere. (5-8)
  • Earth in the solar system
    • The earth is the third planet from the sun in a system that includes the moon, the sun, eight other planets and their moons, and smaller objects, such as asteroids and comets. (5-8)
    • The sun, an average star, is the central and largest body in the solar system. (5-8)
    • Most objects in the solar system are in regular and predictable motion. (5-8)
    • The motions of most objects in the solar system explain such phenomena as the day, the year, phases of the moon, and eclipses.
    • Gravity is the force that keeps planets in orbit around the sun and governs the rest of the motion in the solar system. (5-8)
    • Gravity alone holds us to the earth's surface and explains the phenomena of the tides. (5-8)
    • 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. (5-8)
    • 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. (5-8)
  • Energy in the earth system
    • The sun is the major external source of energy. (9-12)
    • Global climate is determined by energy transfer from the sun at and near the earth's surface. (9-12)
    • The greenhouse effect is the warming effect on the air caused by heat rising from the surface of the Earth and being trapped by gases in the troposphere. (9-12)
  • Origin and evolution of the universe
    • The origin of the universe remains one of the greatest questions in science. (9-12)
    • Early in the history of the universe, matter, primarily the light atoms hydrogen and helium, clumped together by gravitational attraction to form countless trillions of stars. (9-12)
    • Billions of galaxies, each of which is a gravitationally bound cluster of billions of stars, now form most of the visible mass in the universe. (9-12)
    • Fusion and other processes in stars have led to the formation of all the other elements. (9-12)

• Science as Inquiry
  • Abilities necessary to do scientific inquiry
    • Ask a question about objects, organisms, and events in the environment. (K-4)
    • Plan and conduct a simple investigation. (K-4)
    • Use data to construct a reasonable explanation.
    • Identify questions that can be answered through scientific investigations.
    • Design and conduct a scientific investigation.
    • Use appropriate tools and techniques to gather, analyze, and interpret data.
    • Develop descriptions, explanations, predictions, and models using evidence.
    • Think critically and logically to make the relationships between evidence and explanations.
    • Use mathematics in all aspects of scientific inquiry.
  • Understandings about scientific inquiry
    • Scientific investigations involve asking and answering a question and comparing the answer with what scientists already know about the world. (K-4)
    • Current scientific knowledge and understanding guide scientific investigations. (5-8)
    • Mathematics is important in all aspects of scientific inquiry. (5-8)
    • Scientific explanations emphasize evidence, have logically consistent arguments, and use scientific principles, models, and theories. (5-8)
    • Conceptual principles and knowledge guide scientific inquiries. (9-12)
    • Historical and current scientific knowledge influence the design and interpretation of investigations and the evaluation of proposed explanations made by other scientists. (9-12)
    • Mathematics is essential in scientific inquiry. (9-12)
    • In presenting data, graphs are used to convey comparisons or trends. (9-12)
