The need to teach students about alternative energy will continue to gain importance given the increasing growth and demands of the renewable energy industry. This article describes an activity focused on wind energy that the author introduced at the Annual STEM Symposium sponsored by Texas's Region One Education Service Center that can be implemented by teachers in the STEM (science, technology, engineering, and mathematics) fields. The author developed the activity specifically to introduce the concepts of harnessing wind energy, exploring wind energy as power, and the representation of wind energy using multiple forms--tabular, graphical, and numeric. The activity allows for working with the following measurements and investigations: (1) Measurement of wind speed; (2) Measurement of the effects of design on power output; (3) Measurement of optimal wind direction; and (4) Measurement of wind speed over land or water. (Contains 3 figures, 3 tables, 8 photos and 2 online resources.)
