Learners will identify the essential components of a functioning circuit, distinguish between open and closed circuits, and explain how electrical energy transforms into light, thermal, motion, and sound energy in circuits.
investigate and describe the transformation of energy in systems such as energy in a flashlight battery that changes from chemical energy to electrical energy to light energy;
demonstrate that electrical energy in complete circuits can be transformed into motion, light, sound, or thermal energy and identify the requirements for a functioning electrical circuit; and
