The students decided to create an awareness campaign about water pollution in their local area. They focused on a pond that was already polluted and used by the community. They put up posters near the pond to educate people about water pollution. They then went door-to-door, asking people questions about their water usage and providing suggestions to reduce pollution, such as not washing clothes in the pond. They cleaned the pond and surrounding area, removing trash. While initially hesitant, the students felt happy and satisfied that they helped the community after receiving recognition for their work.
