Running water Erosion lab




This week I implemented a lab on running water erosion. I used a stream table, sand and a hose connected to a faucet. Students were put into groups of four for their lab groups. Each group took a turn at the stream table completing four trials. For the first three trials the angle of incline was increased. The students carved a river path and then ran water down the river while watching for erosion and deposition. On the fourth trial, the groups used rocks to try to prevent erosion.


I felt this lab was very sucessful. The students were actively engaged and by the end of the lab, they were able to correctly use the terms: erosion, deposition, oxbow lake and delta.
