Abstract
In this study, the learning of science outside the classroom is believe to be an added value to science learning as well as it offers students to interact with the environment. This study presents data obtained from two days’ workshop on Lichen as Biological Indicator for Air Quality. The aim of the workshop is for the students to gain an understanding on various aspects on Lichens and its role as a biological indicator. Students are exposed to the following concepts and skills in the workshop: characteristics of algae, the concept of Lichen, causes of polluted air, the concept of quadrant, how to measure the frequency of Lichen, types of Lichen, determining the air quality index, factors determining the quality of air, the role of Lichen, the function of Lichen as a biological indicator and determining the level of air pollution. Four schools participated in the two day workshop whereby two schools were located in rural and urban areas respectively. A total of 125 students were given a pre-test on the concept of Lichen before the workshop followed by brief lecture sessions, hands-on and field work activities, presentation by students. At the end of the workshop, students were given a post-test. Overall, from the pre and post-test results, there is a significant difference in terms of students’ performance from all the four schools, in knowledge and skills relating to Lichen and its role as a biological indicator in determining the quality of air.

Summary
The World’s Earth Day which was introduced in 1970 is the beginning of the era of environment. It is necessary to create awareness of environmental problems and issues for the masses. Education plays an important role in providing and creating awareness about environment and the problems associated with it. Awareness of environmental issues is seen as a catalyst to behavioural change towards environment. The main aim of environmental education at school is to create awareness among students about and on environment and the problems as well as inculcation of positive attitudes towards environment. This is to ensure that the students are able to play a more effective role in managing the environment. It is necessary to understand to what extent students are aware of their environment, environmental problems and species that are available in their environment
