Educators throughout the country know The Franklin Institute Science Museum for its innovative teaching resources, both inside the museum and beyond its walls. Perhaps you have already used one of our units of study to teach science in your classroom. Our units of study are designed to stimulate critical thinking about the topic by both you and your students. Hands-on science with inquiry-based facilitation should motivate your students to achieve their goals. We have made our unit for Investigating Wind Energy available for you to use on your own. The activities take an inquiry approach. The series of activities is designed to be done in order, with each building on the previous. However, if you face time constraints, each activity can stand alone. Background The air of our atmosphere moves in many directions and at varying speeds. It can be as gentle as a spring breeze or as dangerous as a tornado. But did you ever wonder about wind? What forces cause air to move? What would Earth's environment be like without the global and local circulation of wind? Air is a fluid which moves in circuits, powered by unequal heating of large masses of air. As the Earth's surface is warmed differentially, the air above these surfaces absorbs different amounts of heat. Warmer air rises while cool air sinks which creates the environment for flowing air movement. Winds flow across parallels of latitude, taking heat from equatorial regions to polar regions. This equalizing process causes wind and is of major importance in determining the environments for life on land, global as well as local weather patterns, and a clean, inexpensive source of energy for humans.

A gentle breeze cools the home on a hot summer day. A colorful kite floats high above the heads of a picnicking family at play. The tinkling of chimes beneath a baby's bedroom window lulls the infant to sleep. With sails unfurled, a sailboat races toward the horizon. The wind is friend. A hurricane roars inland, destroying homes and communities. Without warning, a thunderstorm rolls into town, dampening picnic plans. The slamming of shutters outside a baby's bedroom window shatters the infant's sleep. Surf's up, and the waves pound wickedly, whipping the sailboat toward the rocks. The wind is fierce. Enemy or ally? Friend or foe? Our relationship with the wind is often uncertain. Learn more about our fierce friend by exploring the science of wind energy. Blustery Beginnings Set the scene for studying wind. Begin by selecting background material. Present some of the motivational resources that are available. Gather resources from the bibliography of wind. Once everyone is thinking windy thoughts, move on to the next phase: inquiry-based activities for investigating wind. Investigating Wind Energy A series of four inquiry-based activities provides a framework for investigating the effects of wind and the energy of wind. The first activity offers open-ended exploration of wind's effects on objects. The next activities build on the early exploration, with students building windmill blades to demonstrate their notions of wind. Finally, kinetic energy becomes mechanical when students actually use their windmill to do work.

28. Clean Energy Basics: Introduction To Wind Energy This page provides an introduction to wind energy. http://www.nrel.gov/clean_energy/wind.html

Credit: Warren Gretz Introduction to wind energy wind turbine Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor. A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is actually much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity. Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a photovoltaic (solar cell) system. For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form a wind plant . Several electricity providers today use wind plants to supply power to their customers. Stand-alone wind turbines are typically used for water pumping or communications. However, homeowners, farmers, and ranchers in windy areas can also use wind turbines as a way to cut their electric bills.

31. Residential Wind Energy: Q&A Brief overview on purchasing and operation of a residential wind turbine. http://www.awea.org/faq/rsdntqa.html

State-by-State Info CONTENTS Will I save money? Turbine Sizing Who should buy a turbine? Environmental Benefits ... Where to Buy See the AWEA Publications Catalog for books and videos about small wind turbine applications. What do I need to know to purchase a residential wind turbine? How do residential wind turbines work? A wind turbine, which is installed on top of a tall tower, collects kinetic energy from the wind and converts it to electricity that is compatible with a home's electrical system. In a normal residential application, a home is served simultaneously by the wind turbine and a local utility. If the wind speeds are below cut-in speed (7-10 mph) there will be no output from the turbine and all of the needed power is purchased from the utility. As wind speeds increase, turbine output increases and the amount of power purchased from the utility is proportionately decreased. When the turbine produces more power than the house needs, the extra electricity is sold to the utility. All of this is done automatically. There are no batteries in a modern residential wind system. Small wind systems for remote applications operate somewhat differently.
