This On-Site Field Trip™ consists of a 60-minute session that combines lecture, discussion and activity. Students discuss various types of energy sources and learn renewable vs. non-renewable options. An overview of how wind is formed, captured and transformed into electrical power is presented. Wind power is put into historical and worldwide perspective. Discussion topics of wind, force, power, electricity, old style windmills vs. new technologies are reinforced when students build their very own Vertical Axis Wind Turbine (VAWT). Students keep their VAWT and are encouraged to decorate and personalize it after the class.
