Purpose To help students understand that rivers flood, but not on a schedule. To introduce students to the difference between seasonal floods and great floods. Context This lesson was developed by Dr. Penny Firth, a scientist, Dr. Some of the lessons integrate topics that cross biological, ecological, and physical concepts.
Others involve elements of economics, history, anthropology, and art. Each lesson is framed by plain-language background information for the teacher. This is the second of a strand of three lessons entitled Great Rivers: Where Ecology Meets History.
The lessons address the concept of large rivers as dynamic ecological systems that have had vital influences on human history.
In Great Rivers 1: The Nature of Great Rivers, students are shown the basics of the water cycle. They are introduced to the concept that flowing water carries materials such as silt, plankton, leaves, and wood.
They also learn how rivers and the materials that they carry define how they look and act. The Ups and Downs of River Flooding focuses on flooding, both because of its importance to human history, and because it is often misunderstood.
Key to this lesson is the concept that while some floods may be predictable in a general way i. Great Rivers, Great Givers consists of a variety of brief sketches that illustrate for students how rivers have influenced human history from the dawn of civilization.
Students should know that precipitation is responsible for flooding. When the amount of water entering the river exceeds what it can carry in the channel, the river rises up onto its floodplain. The floodplain is the land on either side of the river banks.
Students may need to be reminded that the precipitation that causes flooding might be distant in either time or space from the flood itself.
For example, precipitation that falls as snow might cause flooding when it melts, long after the snowstorm. And precipitation may cause flooding far downstream from where it fell.
