• Physical Science
  • Position and motion of objects
    • The position of an object can be described by locating it relative to another object or the background. (K-4)
    • An object's motion can be described by tracing and measuring its position over time. (velocity) (K-4)
    • The size of the change of position and motion is related to the strength of the push or pull. (K-4)
    • The position and motion of objects can be changed by pushing or pulling. (K-4)
  • Motion and Forces
    • Objects change their motion only when a net force is applied. Laws of motion are used to calculate precisely the effects of forces on the motion of objects. (9-12)
    • The magnitude of the change in motion can be calculated using the relationship F = ma, which is independent of the nature of the force. (9-12)
    • Whenever one object exerts force on another, a force equal in magnitude and opposite in direction is exerted on the first object. (9-12)
    • Gravitation is a universal force that each mass exerts on any other mass. (9-12)
    • The strength of the gravitational attractive force between two masses is proportional to the masses and inversely proportional to the square of the distance between them. (9-12)
    • Unbalanced forces will cause changes in the speed or direction of an object's motion. (Acceleration) (5-8)
    • The motion of an object can be described by its position, direction of motion, and speed. (5-8)
    • An object that is not being subjected to a force will continue to move at a constant speed and in a straight line. (inertia) (5-8)
    • If more than one force acts on an object along a straight line, then the forces will reinforce or cancel one another, depending on their direction and magnitude. (5-8)

• 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)
    • Employ simple equipment and tools to gather data and extend the senses. (K-4)
    • Use data to construct a reasonable explanation.
    • 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.
    • Identify questions and concepts that guide scientific investigations. (9-12)
  • 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)
    • Types of investigations include describing objects, events, and organisms; classifying them; and doing a fair test (experimenting).
    • Simple instruments, such as magnifiers, thermometers, and rulers, provide more information than scientists obtain using only their senses.
    • Scientists develop explanations using observations (evidence) and what they already know about the world (scientific knowledge). Good explanations are based on evidence from investigations. (K-4)
    • 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)
    • Scientific explanations must adhere to criteria such as: a proposed explanation must be logically consistent; it must abide by the rules of evidence; it must be open to questions and possible modification; and it must be based on historical and current scientific knowledge. (9-12)

• History and Nature of Science
  • Nature of science
    • Scientists formulate and test their explanations of nature using observation, experiments, and theoretical and mathematical models. Those ideas are not likely to change greatly in the future. (5-8)
  • Nature of scientific knowledge
    • Science distinguishes itself from other ways of knowing and from other bodies of knowledge through the use of empirical standards, logical arguments, and skepticism, as scientists strive for the best possible explanations about the natural world. (9-12)
    • Scientific explanations must meet certain criteria. (9-12)
    • First and foremost, scientific explanations must be consistent with experimental and observational evidence about nature, and must make accurate predictions, when appropriate, about systems being studied. (9-12)
    • Scientific explanations should be logical, respect the rules of evidence, be open to criticism, report methods and procedures, and make knowledge public. (9-12)
