Students answer questions in a small group.
Shape the clay so that it gradually slopes down to the body of water. Smooth the clay along the sides of the pan to seal the edges. You can also form meandering streams in the clay that led into the body of the water. Cut a piece of indoor-outdoor carpeting to completely fill the space cross the pan along the edge of the clay. The carpeting represents the wetland buffer between dry land and open water.
