Title: Mixed Vs Layerd

By:Charlise, Anthony, Seth, Layton


What would happen if we layerd the soil instead of mixed?


We think the mixed soil will erode more than the layred soil because we think the layred soil is thicker than the the mixed soil.


Clay, Sand, Gravel, Potting Soil, Stream Table, 2 Angle Blocks, Bowl, Cup(with one hole), Ruler.

Set Up:

The set up was were we had two stream tables and one had mixed soil and the other had layered.

the mixed soil eroded more than the layered soil because we think that the layered soil is thicker than the mixed soil. These pictures are our evidence.
