Pearl the Raindrop: The Great Water Cycle Journey is meant to teach scientific facts to very young children, in a way that they''re able to grasp. Those facts represent the water cycle in which evaporation, condensation, and precipitation occurs. Pearl and Dewey begin as two drops of water within the vast sea. The heat from the sun begins the process of evaporation, wherein Pearl and Dewey become invisible as water vapor. Once the vapor touches the cold air far above, it condenses and becomes a cloud. This is explained as the "shivering" of the droplets of water and their assembling to form a cloud, becoming visible once again. When the cloud is large enough, which is the gathering of all clouds, precipitation then occurs. This is when Pearl follows Dewey from the cloud as rain on the way to meet Sage, the tree. This also explains that trees (and all other plants for that matter) use water to
