-Students will then learn about biological soil crust its benefits to the ecosystem through video and images
-We will then discuss the impacts that human activity can have on biological soil crust
-The class will then be divided into groups and given an activity sheet documenting a current problem facing natural resources in the southwest, and be given a chance to create a management strategy. Students will present their ideas to the class.
-Time will be saved at the end for questions.
