In order to learn more about erosion caused by moving water, we will wait for a heavy rainfall. When it is over, we'll collect samples of the running, muddy water in glass jars. Label the jars in such a way as to indicate the location where the water was collected. Let the water stand for several hours until the contents have settled.

From your observations, you will realize that moving water carries materials and that the materials settle out of the water at different rates.

Compare the kinds of sediments collected from the different locations.

If possible, trace the source of the materials upstream from the places they were collected. There may be visible effects of erosion that could be recognized.
