Electrical energy is a vital part of modern living. It powers a vast number of devices that we use daily, from lightbulbs, televisions, and computers to vacuum cleaners, refrigerators, and air conditioners. Although students may come to the unit with seemingly limited experience with electrical energy, they actually use it routinely—playing with battery-powered toys, watching television, listening to MP3s, and playing video games. Our increasing reliance on electrical energy and the need to generate more electrical power underscores the need for students to understand the nature of electricity. The term “electricity” is used to describe many phenomena associated with electrical energy and electrical circuits. As students participate in the inquiries in this unit, they begin to develop their own understanding of the meaning of electrical current, voltage, power, and electrical energy. They investigate how electrical energy is transferred in electrical circuits and how devices transform electrical energy into other forms of energy.
