This marvelous teaching tool simulates the water cycle as it occurs in nature. A two-piece plastic terrain model is used with ice*, water* and a desk lamp*. Students can create and study firsthand—clouds, fog, rain formation, rivers and melting snow processes. Observe how water evaporates from a lake, collects and condenses on the cloud form, and precipitates onto the land areas. Ten 8½" × 11" color study cards are provided to show students how the water cycle influences our day-to-day life. Also includes an activity notebook with lesson plans and a color transparency for classroom presentation. Model size: 16" L × 12" W × 2½" D.
