Water Cycle Model Activity Set In Stock Now

Water Cycle Model Activity Set includes ten 8-1/2 in x 11 in full color study cards, a teacher-developed activity notebook with lesson plans and a full-color overhead transparency. Fully-functional 3-D model allows the students to duplicate individual processes of evaporation, condensation and precipitation of the water cycle. Set broadens the understanding of water cycle and enhances the awareness of various states of water. To make the model work, "clouds" are filled with ice cubes, "ocean" reservoirs are filled with water and a strong heat lamp is needed for simulation of the "sun". In demonstrations the water evaporates, saturates the air, is cooled and finally condenses to form rain.
