MEANDER CURVE: Why the River Bends
Science Concept:
Friction between water and stream banks causes water to move in a corkscrew fashion. This helical flow is called a water spiral. Gravity and the water spiral are responsible for erosion and deposition in streams.
Alaska Standards
Science Content SD2 Students develop and understanding of the origins, ongoing processes, and forces that shape the structure, composition, and physical history of the Earth.
Science Process SA1 Students develop an understanding of the processes of science used to investigate problems, design and conduct repeatable scientific investigation s, and defend scientific arguments.
Math A6 A student should understand mathematical facts, concepts, principles, and theories. A student who meets the content standard should collect, organize, analyze, interpret, represnet, and formulate questions about data and make reasonable and useful predictions about the certainty, uncertainty, or impossibility of an event.
