The first 3-Day Biotechnology Tasting Programme for PLK Chee Jing Yin Primary School was successfully held on 20, 27 November and 4 December 2021. Our students are responsible for introducing and teaching the primary school students how to conduct experiments. The programme includes the introduction of Biotechnology, micro-organisms, DNA & RNA, DNA electrophoresis and the theory of DNA fingerprinting, which is widely used in forensic science. All the primary school students and our student helpers enjoyed this activity. And we are all looking forward to the coming 3-day tasting programme.
