Indicator

A.   Relate uses, properties and chemical processes to the behavior and/or arrangement of the small particles that compose matter.

1.   Investigate how matter can change forms but the total amount of matter remains constant.

D.   Describe that energy takes many forms, some forms represent kinetic energy and some forms represent potential energy; and during energy transformations the total amount of energy remains constant.

 

2.   Describe how an object can have potential energy due to its position or chemical composition and can have kinetic energy due to its motion.

3.   Identify different forms of energy (e.g., electrical, mechanical, chemical, thermal, nuclear, radiant and acoustic).

4.   Determine that energy can change forms but the total amount of energy remains constant.

5.   Determine the energy transformation(s) in a simple closed system (e.g., a flashlight).

 

C.   Describe renewable and nonrenewable sources of energy (e.g., solar, wind, fossil fuels, biomass, hydroelectricity, geothermal and nuclear energy) and the management of these sources.

6.   Explain that the energy found in nonrenewable resources such as fossil fuels (e.g., oil, coal, and natural gas) originally came from the sun and may renew slowly over millions of years.

7.   Explain that energy derived from renewable resources such as wind and water is assumed to be available indefinitely.

8.   Describe how electric energy can be produced from a variety of sources (e.g., sun, wind and coal).

9.   Describe how renewable and nonrenewable energy resources can be managed (e.g., fossil fuels, trees and water).
