“Low Carbon, No Carbon” was conducted on 13 Oct 2011 from 4:30pm to 5:45pm in our school. It was organized by PSH society with the support from World Wildlife Fund (WWF). About 60 students joined the treasure hunt and poster competition in this activity. Students know more about the consumption of carbon in our school and raise their awareness to protect the environment. Posters displayed on campus can remind students and teachers the importance of living with low carton.
