Secondary 2 students went on a geographical field trip to Punggol Waterway. The purpose of the visit was to study the impact of human activities in a nature reserve/park. The visit was a good opportunity for students to do applied learning and investigate if naturalized rivers support biodiversity, and to gather public opinion on the use of land resources for the construction of waterway parks. Students were able to engage in sampling and water testing using kits recommended by the PUB. They also practised their social and communication skills by interviewing members of the public based on questionnaires they prepared themselves.
