The groundwater model is available for classroom demonstrations for grades 4-12. The model is designed to show  the concepts of groundwater flow and pollution potential.
The model is a cross-section of a soil profile, highlighting the different textures (sand, silt, clay and rock) which make up our soils. Dye is added to the model to demonstrate various types of groundwater pollution. This allows the students to see how pollution can enter into the groundwater supply and the speed at which it travels.

If you are doing a unit about soils or water movement in our soils, the groundwater model would be an excellent tool to relate this concept to your students.  To schedule a classroom demonstration, please contact Deb Bigelow at 393-6724.
