This teacher's manual was developed to provide information on environmental education issues in the Pacific to teachers, extension officers, and other trainers to help make conservation an integral part of their teaching and training activities. The main focus of the activities contained in this manual is to achieve sustainability and enhance the long-term quality of life in the South Pacific. The emphasis throughout is on learning by doing. The manual is divided into four units. The first unit, "Teacher Training for Environmental Education", gives suggestions for teacher training, describes a teacher training workshop and activities, and offers tips for integrating environmental education activities into existing curricula using an interdisciplinary approach. Many of the teacher education activities in this manual may also be appropriate for use in the classroom. The other three units--"Marine Environment", "Pollution", and "Agriculture"--are comprised of classroom activities on those themes and include an overview and activities. Activities address such topics as coastal environment, coral reefs, nuclear pollution, pesticides, development, and changing agricultural practices. Scientific concepts addressed include tides and waves, soil erosion, and water salinity. (PVD)
