This course is included in the geography course for students of Grade 4. The purpose of this course is to make the students aware of sustainable landfill when certain people decide how to use a particular piece of land, the decision can involve and affect many people in many ways. Therefore, students will learn to establish processes for planning and resolving conflicts about land usages. In this simulation, students will develop a plan to address a land-usage issue. Students will survey the area around their school (or their house) to look for the components of the human community in which they live. While this activity focuses on land use, the process can be adapted to examine other issues in their community. Total time allocated for this lesson is 24 hours.
