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 8 1/2" x 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 x 12"W x 2 1/2"D.*Not provided.
