Fourth Grade

Physical Science

Power Standards
  • Use evidence to construct an explanation relating the speed of an object to the energy of that object.  (4-PS3-1)
  • Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat and electric currents. (4-PS3-2)
  • Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move. (4-PS4-1)

Critical Content

Concepts and Skills

* Power Standard Content

PS3.A: Definitions of Energy

  • * The faster a given object is moving, the more energy it possesses. (4-PS3-1)
  • * Energy can be moved from place to place by moving objects or through sound, light, or electric currents. (4-PS3-2 and 4-PS3-3)

PS3.B: Conservation of Energy and Energy Transfer

  • * 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. (4-PS3-2),(4-PS3-3)
  • * 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. (4-PS3-2),(4-PS3-4)

PS4.A: Wave Properties

  • *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. (Note: This grade band endpoint was moved from K–2.) (4-PS4-1)
  • *Waves of the same type can differ in amplitude (height of the wave) and wavelength (spacing between wave peaks). (4-PS4-1)

PS4.B: Electromagnetic Radiation (Spectrum) (Visible Light Waves)

  • In order to see an object, light has to reflect off of that object into your eyes. (Make connection while teaching waves that visible light is a wave.)

PS4.C:  Information Technologies and Instrumentation (4-PS4-3)

  • Digitized information can be transmitted by waves over long distances without significant weakening (interference).  High-tech devices, such as computers or cell phones, can receive and decode information, convert it from digitized form to voice, and vice versa.

Critical Language (Science & Engineering Practices)

Language Usage

  • A student in fourth grade can demonstrate the ability to apply and comprehend critical language by creating and explaining models to represent energy.
