PS Physical Sciences

  • PS1-4 Energy

    • PS1-4-1 Use evidence to construct an explanation relating the speed of an object to the energy of that object.

      • PS1-4-1.PS3.A Definitions of Energy

        • PS1-4-1.PS3.A.i The faster a given object is moving, the more energy it possesses.

    • PS1-4-2 Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.

      • PS1-4-2.PS3.A Definitions of Energy

        • PS1-4-2.PS3.A.i Energy can be moved from place to place by moving objects or through sound, light, or electric currents.

      • PS1-4-2.PS3.B Conservation of Energy and Energy Transfer

        • PS1-4-2.PS3.B.i Energy is present whenever there are moving objects, sound, light, or heat. When objects collide, energy can be transferred from one object to another, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air; as a result, the air gets heated and sound is produced.

        • PS1-4-2.PS3.B.ii Light also transfers energy from place to place.

        • PS1-4-2.PS3.B.iii Energy can also be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light. The currents may have been produced to begin with by transforming the energy of motion into electrical energy.

    • PS1-4-3 Ask questions and predict outcomes about the changes in energy that occur when objects collide.

      • PS1-4-3.PS3.A Definitions of Energy

        • PS1-4-3.PS3.A.i Energy can be moved from place to place by moving objects or through sound, light, or electric currents.

      • PS1-4-3.PS3.B Conservation of Energy and Energy Transfer

        • PS1-4-3.PS3.B.i Energy is present whenever there are moving objects, sound, light, or heat. When objects collide, energy can be transferred from one object to another, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air; as a result, the air gets heated and sound is produced.

      • PS1-4-3.PS3.C Relationship Between Energy and Forces

        • PS1-4-3.PS3.C.i When objects collide, the contact forces transfer energy so as to change the objects' motions.

    • PS1-4-4 Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.

      • PS1-4-4.PS3.B Conservation of Energy and Energy Transfer

        • PS1-4-4.PS3.B.i Energy can also be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light. The currents may have been produced to begin with by transforming the energy of motion into electrical energy.

      • PS1-4-4.PS3.D Energy in Chemical Processes and Everyday Life

        • PS1-4-4.PS3.D.i The expression "produce energy" typically refers to the conversion of stored energy into a desired form for practical use.

      • PS1-4-4.ETS1.A Defining Engineering Problems

  • PS2-4 Waves

    • PS2-4-1 Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.

      • PS2-4-1.PS4.A Wave Properties

        • PS2-4-1.PS4.A.i Waves, which are regular patterns of motion, can be made in water by disturbing the surface. When waves move across the surface of deep water, the water goes up and down in place; there is no net motion in the direction of the wave except when the water meets a beach.

        • PS2-4-1.PS4.A.ii Waves of the same type can differ in amplitude (height of the wave) and wavelength (spacing between wave peaks).

    • PS2-4-2 Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.

      • PS2-4-2.PS4.B Electromagnetic Radiation

        • PS2-4-2.PS4.B.i An object can be seen when light reflected from its surface enters the eyes.

    • PS2-4-3 Generate and compare multiple solutions that use patterns to transfer information.

      • PS2-4-3.PS4.C Information Technologies and Instrumentation

        • PS2-4-3.PS4.C.i Digitized information can be transmitted over long distances without significant degradation. High-tech devices, such as computers or cell phones, can receive and decode information-convert it from digitized form to voice-and vice versa.

      • PS2-4-3.ETS1.C Optimizing the Design Solution

        • PS2-4-3.ETS1.C.i Different solutions need to be tested in order to determine which of them best solves the problem, given the criteria and the constraints.
