GRADES OR AGES: K-6. SUBJECT MATTER: Science. ORGANIZATION AND PHYSICAL APPEARANCE: The guide is divided into six straight-text chapters. One chapter, which outlines curriculum units, is subdivided by grade level--primary, intermediate, or upper elementary. The guide is offset printed and spiral-bound with a paper cover. OBJECTIVES AND ACTIVITIES: A rationale and general objectives for science teaching are presented in the first two short chapters. Another chapter contains suggested curriculum units with specific suggestions for activities. Each group of activities is correlated with a scientific concept or phenomenon. A second chapter presents general guidelines for out-of-school activities such as hikes and field trips, and an appendix contains detailed descriptions of 45 experiments. INSTRUCTIONAL MATERIALS: Materials needed for the experiments are listed at the beginning of each description. Guidelines for the use of materials and resources and a list of selected references are also included. STUDENT ASSESSMENT: The guide includes sample rating forms for student reports and experiments and suggests guidelines for constructing written tests. (RT)
