Rain that falls onto the land either soaks into the ground or runs off. Water that runs off follows tiny channels, or streams. These little streams flow into bigger streams and rivers. Some flow into lakes or wetlands. All the land from which this water flows is called a watershed. Let's build one!
That food coloring could represent pollution. Did it move through the rest of the watershed? How might that pollution affect the rest of the watershed? How would you feel if you lived downstream from that pollution? How would you feel if you lived upstream from that pollution?
You might be glad that the pollution didn't flow past you. But did you ever hear the saying, "We all live downstream"? Each of us lives in a watershed. Watersheds are connected. Things that we do to the water in one area affect the water many, many miles away.
In the real world, many things change the water in our watersheds. Make a list of the natural and human things that shape the water habitats in the watershed.
