Students investigate the effects of a rising watertable on the soil and plants in an area.
This activity starts with some simple activities that illustrate two aspects of watertable management. The first activity shows how trees can lower the level of watertables by transpiration. The second activity shows how salt below the earth can be brought to the surface by a rising watertable. Both activities encourage students to consider the consequences of management strategies. A number of different plants would be suitable for this activity.
