This is one of a series of units for environmental education developed by the Highline Public Schools. The unit for elementary students in intermediate grades is concerned with nutrition, basic food groups, food production careers, future trends in food production and population growth, and ecology. The unit of 18 lessons is to be used over a six week time span with lessons each day. The length of each lesson varies from 30 minutes to several hours. Each lesson includes the concept of the lesson, materials needed, notes to the teacher, procedure, evaluation activities, and suggested extra activities. The materials were tried and evaluated; evaluation data may be obtained from the Highline Public Schools. (RH)
