Energy Forms, States and Conversions

(Complete Item Description)

Abstract:: The students participate in many demonstrations during the first day of this lesson to learn basic concepts related to the forms and states of energy. This knowledge is then applied the second day as they assess various everyday objects to determine what forms of energy are transformed to accomplish the object's intended task. The students use block diagrams to illustrate the form and state of energy flowing into and out of the process.

Get Charged!

(Complete Item Description)

Abstract:: Students are introduced to the idea of electrical energy. They learn about the relationships between charge, voltage, current and resistance. They discover that electrical energy is the form of energy that powers most of their household appliances and toys. In the associated activities, students learn how a circuit works and test materials to see if they conduct electricity. Building upon a general understanding of electrical energy, they design their own potato power experiment. In two literacy activities, students learn about the electrical power grid and blackouts.
