This is one of a series of units for environmental education developed by the Highline Public Schools. The unit has been constructed for use by intermediate grade elementary school pupils. The seven lessons are designed to inform students about the land to develop a land ethic. The unit should be able to be completed in two to three weeks. The fifth lesson is a three hour field trip; the other lessons occur in the classroom and should take from one-half to one hour each. (RH)
