Water, water, everywhere. Fresh water is one of Earth's most precious natural resources. All living things need water to survive, but humans also use water in many other ways. We cook with water. We clean with water. We use water to make paper and medicine. We even use it to make electricity. Natural resources are gifts that Earth gives us. The more we use it, the more important it is to take care of this supply. Color photographs, fact boxes, a hands-on activity, and Words to Know are also included in this earth science title.
