Power at its Source

The government has descriptive sites on
energy production. One of them is on producing electricity from water, that is, hydroelectric power. The process is illustrated in an easy to follow format.

Water can be used to produce power:
Look at a hydroelectric power system-

See a turbine-

Wind can also be used to generate power:

You can generate power by turning a crank:

It would be good to work with pin wheels, water wheels or crank generators in lab activities or experiments to help understand the points made. Similarly field trips to old mills, singing, "Old Mill Stream," or visiting a farm where a wind mill is used, or touring the windmills of New York State (part of the Dutch settlers' cultural heritage and positive influence on the state), or in several other other states (Illinois, Indiana,Ohio, Wisconsin, Michigan, Iowa ...), would also enhance learning about sustainable energy and power generation. (If you know a good website on windmills in your state, please add it to the comments.)
