Soil Erosion Demonstration
 Fill plastic bottles with "hot" water and peel the labels off. |
 Cut bottles to make the erosion model and pierce cap with hot needle. |
 Experiment by applying different mulches to the surface or by using soils with different percent organic matter. (Garden vs. Forested Soils) |
 Soils high in organic matter and soils covered with mulch will yield clearer runoff than bare soils or soils low in organic matter. |
