This three-dimensional demonstrator creates a water cycle as it occurs in nature. A fascinating, ingenious experimental model that actually causes the rain to fall on the terrain, flow down the slopes, form a body of water, then evaporate in a continuous cycle. It also graphically shows distillation of water as it changes to gas. Students can examine the evaporation and condensation process within the plastic model. Study cards encourage hands-on learning.
Teacher developed activity notebook also includes a full-color overhead transparency and basic understandings to support classroom activity.
