Here are some PowerPoint slides I developed for teaching my students about the water cycle - also known as the hydrologic cycle. I introduced them to how important water is (although you don't need to be an environmental science teacher to know that), the terms used to describe how water moves around the Earth and the atmosphere, and what humans are doing to alter the natural movement of water.As always, feel free to use these slides however you would like. Knowledge should be open and free.
