Hydropower has been used for hundreds of years in watermills and is now commonly used to generate electricity in applications such as hydroelectric dams and tidal power plants. Explore the power of water by building models and 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 and 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 and cohesion. Learn about water pressure by building a water tower communicating vessels and a water fountain. Construct a hydroelectric power station to generate electricity and light an LED. Learn about where the energy in ocean waves tides and rivers comes from and discover how we can generate electricity from them.
