3—The Water Cycle
Before you learn about saving water, let's take a look at how the water cycle works. Did you know that the glass of water you drank today may have been the same water a dinosaur drank millions of years ago? It's true! The water on earth changes form from water to vapor to ice or snow, but there is the same amount of water now as when T Rex was strutting around, and the water has been continually recycling all this time. This cycling is called the water cycle. Click here for a water cycle activity. To get back to this page from the activity, just click the Return to Tour button on the control panel to the right.
