learn something about hydroelectric dams. Specifically, address these questions: What are the properties of a dam that allow large energy? What are the properties that allow large power? One way to study this is to look up examples such as the Hoover Dam, Kentucky Dam, and the Mother Ann Lee Hydroelectric station on the internet. Put this in paragraph form. Please site all references used. This info below is a definition for Energy and Power! Definition: Energy is what you have to add to make cold things warmer and slow things faster, or to lift something up. Energy comes in many forms. We add energy when we charge a battery or compress a spring. When we pay the gas bill or the electrical bill we are paying for the energy we used. Power means energy per unit time. To keep many lights on or many machines running at once, you need high power. Power is measured in watts. If you multiply the amount of time by the amount of power, you get the energy that was used or delivered. A thousand watt device running for one hour uses 1 kilowatt-hour, which is about 7 cents worth of energy. "kilo" is an abbreviation for 1000. A kilometer is 1000 meters, a kilogram is 1000 grams, a kilobyte is 1000 bytes (whatever those are), and a kilowatt is 1000 watts (but a killer whale is not 1000 whales, and the novel 'To kill a mockingbird' does not involve 2000 mockingbirds). "mega" is an abbreviation for 1,000,000. A megawatt is a million watts. You will also hear about megahertz, megabyte, and megabucks; you could invent units megasecond (a bit more than a day), megameter (1000 km = 621 miles), and megagram (1000 kilograms, which is more commonly called a metric ton or "tonne"; it's 10% more than a ton = 2000 pounds)
