On 8 October 2022, CityU held the first-ever "HK TECH Tiger Tasting Class", inviting STEM outstanding students from Secondary 4 to Secondary 6 among 22 secondary schools in Hong Kong to experience university life for a day in CityU. Prof. Kenneth Leung, Director of the State Key Laboratory of Marine Pollution, warmly welcomed 10 students from 6 secondary schools in the afternoon session, and made a detailed introduction of the academic studies and significant achievements of the laboratory, giving them a preliminary understanding of marine ecological research. During the subsequent tour of the laboratory, the researchers prepared a wealth of graphic contents to help the students understand some more complex marine research projects, and gave them hands-on demonstrations of the advanced equipment, which greatly enriched the students’ knowledge of marine conservation in Hong Kong.
