This guide for teaching nutrition is Book Three in Project Life Lab's (Santa Cruz, California) three-part curriculum for a garden-based science and nutrition program for grades 2-6. The curriculum is designed for use as an integrated program, but the books can be used independently. It is suggested that the use of student journals can greatly enhance the effectiveness of the curriculum by providing a place for students to record data and observations as well as feelings. The use of journals is referred to in many of the lessons. Divided into six units, this book contains lessons on: (1) food choices; (2) the basic four food groups; (3) nutrients; (4) digestion; (5) food consumerism; and (6) recipes for snacks based upon information learned in the preceding lessons. Each lesson provides the stated purpose of the lesson, a list of all necessary materials, the type of activity to be carried out along with needed background information, discussion questions for tying the lesson together, and additional activities and follow-up lessons.
