You need to understand the differences between forms and sources energy to talk about and make informed decisions about energy choices.
Forms of energy are terms scientists use to classify the main types of energy— kinetic and potential. Radiant (light), thermal (heat), and mechanical (motion) energy are examples of forms of energy.
Sources of energy are resources that supply the energy needed to heat our homes, run our appliances, and move our automobiles. Petroleum, coal, and wind are examples of natural energy sources.
At the end of the lesson, students will:
- describe the main forms of energy and give examples
- explain what an energy transformation is and diagram the transformations that take place in an energy system, highlighting waste heat at each step
- state the major sources of energy and identify them as either renewable or nonrenewable
- differentiate between forms and sources of energy
- identify the form of energy stored or delivered in each of the major energy sources
