This lesson plan aims to teach students about water pollution through various activities. The objectives are for students to identify human practices that cause water pollution, role play ways to conserve water resources, and create a slogan campaigning against water pollution. The lesson will include a video on water pollution, a class discussion on the causes and effects of water pollution, and group activities listing human practices that pollute water and ways to minimize pollution. Students will then reflect on the importance of keeping water clean and not littering in rivers. The goal is for students to understand what water pollution is, its different sources, and how citizens can prevent it.
