  • 4-PS3 Energy

    • 4-PS3-1 Use evidence to construct an explanation relating the speed of an object to the energy of that object.

    • 4-PS3-2 Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.

    • 4-PS3-3 Ask questions and predict outcomes about the changes in energy that occur when objects collide.

    • 4-PS3-4 Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.

  • 4-PS4 Waves and Their Applications in Technologies for Information Transfer

    • 4-PS4-1 Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.

    • 4-PS4-2 Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.

    • 4-PS4-3 Generate and compare multiple solutions that use patterns to transfer information.
