Wind is one of the most promising sources of clean, renewable energy available today. With this kit, you can assemble a realistic wind turbine complete with electric generator and adjustable rotor blades that are designed with complex aerodynamic curves to look and work like modern-day wind turbine blades. Then, conduct experiments to optimize the turbine’s performance by adjusting the angle of the blades and discover how to 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 the stored electricity.
The full-color, 32-page manual offers illustrated instructions and scientific information that explores the 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.

Have you ever wondered how a weather forecaster knows what the weather will be like? In All About Meteorology, young students will see how meteorologists can predict the weather for the upcoming week and even a few months down the road through scientific deduction and high-tech equipment. Students will visit with Dr. Jon Nese, chief meteorologist at The Franklin Institute Science Museum in Philadelphia, to get an up-close look at the equipment that meteorologists use to forecast the weather and explore such concepts as the water cycle and air pressure.
