4-PS Physical Science

  • 4-PS3 Energy

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

      • State assessment will be limited to analysis of kinetic energy.

      • Accounting for mass, quantitative measures of changes in the speed of an object, or any precise or quantitative definition of energy are not expected in state assessment.

    • 4-PS3-2 Make observations to show 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.

      • Analysis of forces or quantitative measurements of energy are not expected in state assessment.

    • 4-PS3-4 Apply scientific principles of energy and motion to test and refine a device that converts kinetic energy to electrical energy or uses stored energy to cause motion or produce light or sound.

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

    • 4-PS4-1 Develop a model of a simple mechanical wave (including sound) to communicate that waves (a) are regular patterns of motion along which energy travels, and (b) can cause objects to move.

      • Interference effects, electromagnetic waves, or non-periodic waves are not expected in state assessment.

    • 4-PS4-2 Develop a model to describe that light must reflect off an object and enter the eye for the object to be seen.

      • Specific colors reflected and seen, the cellular mechanisms of vision, angles of incidence and reflection, or how the retina works are not expected in state assessment.

    • 4-PS4-3 Develop and compare multiple ways to transfer information through encoding, sending, receiving, and decoding a pattern.
