In this lesson, suggested for grades K-2, students take two virtual visits to a zoo—one by reading a book and the other by conducting online research. Students are asked to use their observational skills to spot the ways that parents and offspring are alike and different and to look for those protective behaviors that support the survival of young animals. This lesson also raises the controversial question of whether we need zoos. Before beginning the lesson, we recommend reading Units I and IV, which are included in this book selection. A list of materials, teacher background information, safety notes, standards, assessments, references, and resources are provided. This book selection also includes the Table of Contents, Dedication, About the Author, Acknowledgments, Appendix, and Index.
