Simulators

The Landscape Model is ideal for demonstrating both stormwater runoff and how a watershed functions. This sustainable watershed model made from wood with some ceramic props. Pollution sources such as leaking automobile fluids, car wash soaps, pet wastes, construction runoff, farm animal waste, and lawn chemicals are demonstrated with natural powders. The students can then simulate rain or wind and then visualize how the pollution ends up in the surface waters of the watershed. The model can hold water and is fun for students to demonstrate rain with a spray bottle and then watch were the pollution goes.$525


The Water Conservation Model demonstrates the importance of groundwater infiltration in addition to the importance of water conservation. This sustainable simulator is made of ceramics, where moss and tree limbs can be used to represent grass and trees. This model shows that the goundwater we use at home is linked to the nearby lakes and streams. Students use water pumps to simulate the use of water at home. The water slowly diminishes in the nearby lake and stream, leaving the the aquatic life without water. Then a spray bottle is uesd to simulate rain and then the water in the lake and stream are replenished. However, a driveway prop illustrates what happens when the ground is covered with impermeable surfaces. The water will not percolate into the ground and subsequenly the lake and stream will not fill back up. $195
