Recognize that electricity in circuits can produce light, heat, sound, and magnetic effects.
Energy is necessary for change to occur in matter. Energy can be stored, transferred and transformed, but cannot be destroyed.
No resources have been tagged as aligned with this standard.
Explain how electrical circuits can be used to transfer energy in order to produce heat, light, sound, and chemical changes.
Demonstrate how to produce a magnetic force with an electric current, such as an electromagnet, and how to produce an electric current with a magnet, such as a generator.
Recognize that just as electric currents can produce magnetic forces, magnets can cause electric currents.
