It's hard to imagine--the molecules in the glass of water you just finished might have once been part of a water hole that dinosaurs drank from In this fascinating new book by Robert E. Wells about the water cycle, readers will find that while it might be hard to imagine, it's true. In a conversational tone, Wells tells us that water is the only substance found naturally in three states of matter--liquid, solid, and gas. He explains the complete water cycle and also discusses ocean currents, ocean and lake habitats, and hydroelectricity. Finally, the author touches on water pollution and our responsibility to keep our water clean. The author's bright cartoon illustrations make this information especially appealing to kids.
