In this lesson, students continue to address the Rainwater Roundup Challenge as they determine the best shape and dimensions for a storage container for rainwater collection. Students compare their rain gauge data with rainfall data from previous years and use graphing to track monthly rain totals using historical data. Students also research strengths and weaknesses of irrigation and water collection systems. 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.
