This problem focuses on how the body changes the materials of things we eat into our own tissue. How do animals and plants use food? Why do we not become what we eat? Students often wonder if the saying “you are what you eat” makes sense. In this problem, students investigate how the body can break down the molecules that make up what you eat and turn it into the molecules that make up your own body. This problem can be modified to use any vegetable or fruit familiar to students. A materials list, teacher background information, safety practices, references, assessment, and outcomes are provided. This book selection includes the Table of Contents, Preface, Catalog of Problems, Acknowledgments, About the Authors, References, and Index.
