The students noticed that the local waste land was being used by children to play but it was covered in grass and rubbish. They decided to clean up the area to create a playground. They gathered the local children to help clean the area. To pay for cleaning tools, they collected and sold old newspapers and books. In the end, they spent an hour daily cleaning up the area. Now the children have a neat playground to enjoy and the local community appreciates having a cleaner space.
