- Disciplinary Core Ideas
- PS3.B Light also transfers energy from place to place.
PS3.B 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.
