Recognize that energy has the ability to create change.

Given a specific example or illustration (e.g., simple closed circuit, rubbing hands together) predict the observable effects of energy (i.e., the bulb lights, a bell rings, hands warm up). A test item may ask, “What will happen when…?”

Recognize that energy, in the form of heat, is usually a by-product when one form of energy is changed to another, such as when machines convert stored energy to motion.

Identify the various forms of energy, such as electrical, light, heat, sound.

Compare a variety of forms of energy, including heat, light, sound, mechanical, electrical, and chemical energy.
