Students simulate a process of land development in a physically involving activity.
All around us, and all over the planet, wildlife habitat is being lost. Whenever an area of land is paved for a shopping center, divided and excavated for homes for people, and sometimes when it is plowed to grow a crop - small animals lose their homes, and frequently their sources of food and water. As these small animals disappear, so too do the larger animals that previously depended upon the smaller animals in the food chain as a source of food. Animals that cannot tolerate human intervention may also disappear without any direct relationship to the food chain. Students can observe this phenomenon near their homes and schools or at least in their region.
