PS Physical Science

  • Energy

    • 1 Use evidence to explain the relationship of the speed of an object to the energy of that object.

    • 2 Plan and carry out investigations that explain transference of energy from place to place by sound, light, heat, and electric currents.

    • 3 Investigate to determine changes in energy resulting from increases or decreases in speed that occur when objects collide.

    • 4 Design, construct, and test a device that changes energy from one form to another (e.g., electric circuits converting electrical energy into motion, light, or sound energy; a passive solar heater converting light energy into heat energy).

    • 5 Compile information to describe how the use of energy derived from natural renewable and nonrenewable resources affects the environment (e.g., constructing dams to harness energy from water, a renewable resource, while causing a loss of animal habitats; burning of fossil fuels, a nonrenewable resource, while causing an increase in air pollution; installing solar panels to harness energy from the sun, a renewable resource, while requiring specialized materials that necessitate mining).

  • Waves and Their Applications in Technologies for Information Transfer

    • 6 Develop a model of waves to describe patterns in terms of amplitude and wavelength, and including that waves can cause objects to move.

    • 7 Develop and use models to show multiple solutions in which patterns are used to transfer information (e.g., using a grid of 1s and 0s representing black and white to send information about a picture, using drums to send coded information through sound waves, using Morse code to send a message).

    • 8 Construct a model to explain that an object can be seen when light reflected from its surface enters the eyes.
