Energy is what causes things to happen. Simply stated, energy is the ability to do work. Energy exists in a number of different forms. The various forms of energy include: chemical, electrical, heat (thermal), light (radiant), mechanical, and nuclear. Fortunately energy can be transformed from one type to another. A battery operated car will transfer electrical energy produced either from nuclear or chemical (coal or gas) into chemical energy stored into its batteries, into mechanical energy as it moves. Energy can also transferred from place to place or between objects. When this happens, energy always flows from where it is at higher levels to where it is lowest.Conceptual StrandVarious forms of energy are constantly being transformed into other types without any net loss of energy from the system.Guiding QuestionWhat basic energy related ideas are essential for understanding the dependency of the natural and man-made worlds on energy?
Elements within this Standard
Grade Level Expectation
Distinguish among heat, radiant, and chemical forms of energy.
Explain how energy is transferred in a simple electrical circuit.
