Stream Explanations

The role of water in changing the Earth's surface was a fundamental conceptual outcome for this unit. As we continued our exploration into stream studies, the students were able to investigate how the speed of water affects and changes earth materials. The students discovered that water flows faster when it is at a steeper angle. Which in turn affects the amount of soil, rock and sand that that stream can carry. The students explored this concept by measuring the travel time of objects in fast (steep) and slow (level) water systems. From this experience they constructed that quickly moving water erodes and deposits earth material, thus changing the surface of the Earth.
