On 12 May, the Physical Education Department led 30 students and parents to participate in a snorkelling and beach cleaning experience organized by the Hong Kong Diving Adventure at the Sharp Island in Sai Kung. Through snorkeling activities, students not only learned snorkelling skills but also had the opportunity to learn about the marine ecology and coral reefs in Hong Kong waters. Through the beach cleaning activity, students gained an understanding of the impact of marine pollution and how we can preserve the beautiful scenery of the beach.
