Each group developed their own research topics and collected their own data: one group studied how the plastic content in the sand changed with distance from the beach, while another group investigated how ocean winds and waves changed the shape of the beach and the growth of plants. The IB curriculum requires students to work on collaborative projects in science to develop critical and creative thinking and collaboration skills. This is called the Group 4 Project (G4P).

 In addition to the fieldwork, all the students cleaned up the beach together. As a sign of appreciation, the local people treated us to curry for lunch, making it a day full of both heart and stomach.
