Among the activities, for example, students collect data on the rate of water absorption of local soils, use a block of ice containing sand and stones to simulate the abrasive action of a glacier, and use a model of a hillside to investigate how contour farming practices reduce erosion. This guide includes a collection of 18 readings that provide detailed explanations and additional examples of the concepts explored in the activities. The topics include glaciers, clouds, acid rain, soil erosion, the water cycle, water treatment, water conservation, and seawater. Each activity includes background information, detailed instructions, reproducible students sheets, extension ideas, and answers when needed. Most of the activities can be adapted for classroom demonstrations.
Audiovisual activities are an integral part of some activities.
