Avista has available a one-hour hydropower presentation for grades 4-6. The presentation features a three-dimensional scale model of a complete hydroelectric system, including a miniature hand-crank generator. It also includes a ten-minute video on hydropower in the Northwest, a slide show, a question and answer session, and "hydro pop-ups" (paper cut-out models of a dam) for all students.

The program demonstrates how dams produce hydroelectric power. The scale model shows how more energy must be produced when additional electrical appliances are used ("peaking power"). To power more appliances, students must turn the hand crank faster, thus producing a greater amount of electricity.

As part of the presentation, the "hydrologic cycle" is described. Renewable versus non-renewable sources of electrical generation are discussed. Students are shown both the positive and negative impacts of hydroelectric power generation. The importance of heeding warning signs and other public safety devices around dams is also emphasized.

The preferred time to schedule this presentation is in the spring, prior to going on a tour of a hydroelectric dam. Upon request, dam tours are available for Avista’s Post Falls, Upper Falls, Cabinet Gorge, Nine Mile, Noxon Rapids, and Long Lake dams. Best time to take a tour is during the spring runoff (April and May), when spillgates are open and the students have a more spectacular view of the cascading water.

The presentation and/or hydroelectric dam tours can be scheduled by contacting Hydro Safety Coordinator Dave Ayres at either the phone number or e-mail address listed below:
