This is one of a series of units for environmental education developed by the Highline Public Schools. The emphasis of the 10 lessons in this unit is on energy, the earth's resources, and the use of earth resources, by man and other living things. The materials are designed for use at grade 1, but could be used in higher grades. Each lesson usually includes the concept of the lesson, materials needed, notes to the teacher, procedure, evaluative activities, and additional suggested activities. The materials were tried and evaluated; evaluation data may be obtained from the Highline Public Schools. (RH)
