Water is always flowing. It runs down your street after a rainstorm, or trickles in a brook near your house. The brook may join a stream, which feeds into a river, which winds its way to the ocean. What a journey! You can follow the water on its long journey to the ocean and learn how water shapes the earth, how people use water, and why it's important to keep our water clean.
