This chapter is devoted to creating a cloth and paper model of the river valley that can be used for many lessons. The basic activity, "Changing River," provides a setting for the subsequent activities that explore the roles of animals, plants, cottonwood trees, agriculture, and change in the river of the past, the present, and the future. The River of Change model, which is designed for classroom use, is unique to this program and provides a hands-on approach to understanding river ecology.
