HYDROPOWER

624811 AGES 8+ MSRP: $49.95 CASE PACK QTY: 5 EXPERIMENTS: 12 PIECE COUNT: 105 MANUAL PAGES: 32 Explore the power of water by building models and conducting experiments with them. Build a waterwheel, a sawmill, and a hammer mill to harness the energy of moving water to do different types of physical work. 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 capture energy from them.

WIND POWER

Build a realistic wind turbine to harness power out of thin air. Wind is one of the most promising sources of clean, renewable energy available today. Wind energy has been used for centuries to pump water and crush grain in windmills, and is increasingly being used to generate electricity to power our modern world.

Assemble a wind turbine complete with electric generator and adjustable rotor blades. The blades are designed with complex aerodynamic curves to look and work like modern-day wind turbine blades. Conduct experiments with your wind turbine, including experiments to optimize its performance by adjusting the angle of the blades and the placement of the turbine. Use the wind turbine to light up an LED and charge a rechargeable battery. Convert the generator into an electric motor and assemble a small electric car to demonstrate a tangible application for stored solar electricity.

Discover how the sun makes the wind, providing us with an endless source of energy. Read about different types of wind turbines and windmills, the history of this technology, and how wind energy can be used to power homes and electric cars. The full-color, 32-page manual offers illustrated instructions and scientific information.
