Modeling Erosion

Here are some pictures from our Modeling Erosion Lab. Students are trying to figure our how water can erode soil. We look used sand, humus, and a combination of the two. There was a lot of variation in the data depending how students set their experiment up, but that was important for the students to see, since there is a great deal of variety with erosion in real life too. Things such as soil type, temperature, soil depth, location, etc., can all effect how the soil erodes.
