This lesson begins with a student email to the teacher for the class bringing to their attention a big problem with the rainwater-recycling project—gravity! Students are challenged to help create solutions for this problem. To move forward with the project, teams must determine whether they should continue with the plan to harvest parking lot water or to consider capturing the rainwater that falls on the two buildings on either side of the garden. They create proposals for solving the problem and present them to stakeholders in an oral presentation. A materials list, safety notes, standards, teacher background information, assessment, and Internet resources are provided. This book selection also includes the Table of Contents, About the Editors and Authors, Acknowledgments, Appendix, and Index.
