In this lesson, students investigate the economics of wind farms, their environmental impacts, and wind turbine blade design. Students consider the advantages and disadvantages of using wind energy, and then use the engineering design process (EDP) and the scientific method to create and test models of various blade designs. We recommend reading Chapter 3, which is included in this book selection and provides a module overview and summary. A materials list, teacher background information, safety notes, standards, assessment, resources, and references are provided. This book selection also includes the Table of Contents, About the Editors and Authors, Acknowledgments, Appendix, and Index.
