• Physical Science
  • Position and motion of objects
    • An object's motion can be described by tracing and measuring its position over time. (velocity)
    • Sound is produced by vibrating objects.
  • Light, heat, electricity, and magnetism
    • Light can be reflected by a mirror, refracted by a lens, or absorbed by the object.
  • Transfer of Energy
    • 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.
    • 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.
    • The sun's energy arrives as light with a range of wavelengths, consisting of visible light, infrared, and ultraviolet radiation.
  • 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)
    • The electric force is a universal force that exists between any two charged objects. (9-12)
    • Opposite charges attract while like charges repel. (9-12)
    • The strength of the force is proportional to the charges and, as with gravitation, inversely proportional to the square of the distance between them. (9-12)
    • Electricity and magnetism are two aspects of a single electromagnetic force. (9-12)
    • Moving electric charges produce magnetic forces, and moving magnets produce electric forces. (9-12)
    • Unbalanced forces will cause changes in the speed or direction of an object's motion. (Acceleration)
    • The motion of an object can be described by its position, direction of motion, and speed.
    • An object that is not being subjected to a force will continue to move at a constant speed and in a straight line. (inertia)
    • 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.
  • Interactions of energy and matter
    • Waves, including sound and seismic waves, waves on water, and light waves, have energy and can transfer energy when they interact with matter. (9-12)
    • Electromagnetic waves result when a charged object is accelerated or decelerated. (9-12)
    • Electromagnetic waves include radio waves (the longest wavelength), microwaves, infrared radiation (radiant heat), visible light, ultraviolet radiation, x-rays, and gamma rays. (9-12)
    • The energy of electromagnetic waves is carried in packets whose magnitude is inversely proportional to the wavelength. (9-12)

• Science as Inquiry
  • Abilities necessary to do scientific inquiry
    • Think critically and logically to make the relationships between evidence and explanations.
  • Understandings about scientific inquiry
    • In presenting data, graphs are used to convey comparisons or trends. (9-12)

• Teaching Standards
  • Teachers provide students with the time, space, and resources needed to learn science.
    • Create a setting for student work that is flexible and supportive of science inquiry.
    • Make the available science tools, materials, media, and technological resources accessible to students.
