In this global citizenship lesson plan, students play international detective as they read accounts of international pollution issues. Students also complete an activity tracing ocean currents and discussing the paths of pollution. These activities prepare students to identify the mindset of a global citizen and to define global citizenship. This lesson reinforces concepts from “Citizen Me” and can be followed by “Students Engage!” but can also be taught independently. Note: This lesson contains an optional PowerPoint presentation (see Lesson Prep).
