PS Physical science

  • PS-1 Energy

    • PS-1.1 Use evidence to construct an explanation relating the speed of an object to the energy of that object.

    • PS-1.2 Make observations to provide evidence that energy can be transferred by heat, sound, light, and electric currents.

    • PS-1.3 Ask questions and predict outcomes about the changes in energy that occur when objects collide.

    • PS-1.4 Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.

  • PS-2 Waves

    • PS-2.1 Develop a model of a simple mechanical wave to describe patterns of amplitude and wavelength and that waves can cause objects to move.

    • PS-2.2 Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.

    • PS-2.3 Generate and compare multiple solutions that use patterns to transfer information.
