Earth Science for Children: All About the Water Cycle

Product Description

Even though nearly three-fourths of the world’s surface is covered by water, only a very small portion of it is fresh water. So what happens when it’s all used up? It won’t, which is just one of the amazing facts children will learn in All About the Water Cycle. Discover the amazing process by which Earth’s water supply has been recycled over millions of years, centering on three stages: evaporation, condensation and precipitation. Follow the trail that water takes after it falls from the sky, and learn what steps scientists are taking to protect Earth’s water supply from the dangers of pollution. A visit to an underground cavern examines the role that water plays in creating these natural wonders, while a lively, hands-on demonstration shows how to create a mini-water cycle in a bowl. Part of the Earth Science for Children DVD Series.
