Gravity from the moon creates ocean tides on earth that go out two times a day, every day of the year. This effect of the moon's gravity on the oceans can be harnessed and turned into power. In fact, people have been using the power of the tides to do work for centuries. This program explores how tidal power is generated and how it works. It illustrates how the tides are created, how watermills once used the tides to grind grain, and how modern power plants use turbines to turn this constant flow of water into electricity. It also discusses how tidal power plants can work without damming estuaries and rivers. Comes complete with online teachers guide which includes subject matter revision and suggestions on how to present material, questions to ask students, career possibilities and class projects to help illustrate the key concepts.
