A Parent’s Choice Recommended Award Winner! Hydropower has been used for hundreds of years in watermills & is now commonly used to generate electricity in applications such as hydroelectric dams & tidal power plants. Explore the power of water by building models & conducting experiments with them. Learn about how different devices are used to extract useful energy from moving water — from a waterwheel in a small stream to a giant turbine in a tidal power station. Build a waterwheel, a sawmill, & a hammer mill to harness the energy of moving water to do different types of physical work. Investigate the intriguing properties of water by performing experiments involving surface tension, adhesion, & cohesion. Learn about water pressure by building a water tower, communicating vessels, & a water fountain. Construct a hydroelectric power station to generate electricity & light an LED. Learn about where the energy in ocean waves, tides, & rivers comes from, & discover how we can generate electricity from them. The full-colour, 32-page experiment manual offers illustrated instructions & scientific information. Ages 8 & up.
