Students discover that topsoil is a nonrenewable resource and use an apple to represent how Earth’s land resources are used. Through critical thinking, students study agricultural land use and consider the sustainability of current land use practices including the use of land to feed and graze livestock animals. Grades 9-12

Using various forms of maps, students will analyze public lands in the western United States, describe how ranchers raise food and fiber on federally owned land, and discuss different points of view concerning public lands use and public lands grazing. This lesson covers a socioscientific issue and aims to provide students with tools to evaluate science within the context of social and economic points of view. Grades 9-12
