Bill Nye the Science Guy demonstrates the phases of the water cycle, from evaporation to condensation to precipitation to collection, in this classroom edition episode of the Emmy Award-winning Disney Channel series. Featuring an interactive question-and-answer format and hands-on activities, the program follows Bill as he builds a model of the water cycle by using a tiny staircase, wind-up penguins and a bicycle tire, before hitting the streets to show children easy ways to help protect the Earth's water supply. Designed to correlate with National Science Standards, the program includes a teacher's guide filled with suggestions for extension activities and classroom experiments.
