Abstract
This paper describes the outcome of the study that was conducted to evaluate the impact of green chemistry experiments on environmental values of pre-service teachers. A total of 110 undergraduate student teachers enrolled in the Chemistry Teaching Methods Level II course were involved in the study. The study employed a one sample pre-post test design. The students were assigned to do five green chemistry experiments for five weeks with one experiment per week. Discussions relating the chemistry concepts to environmental issues were conducted as part of the post-lab discussion. The experiments were conducted in groups of 2-3 students and supervised by the course instructor and tutor. The questionnaire on environmental values was administered at the beginning of the semester and again at the end of seventh week. The results showed that the pre-service teachers were found to be more ecocentric and less homocentric and egocentric. Egocentric values revolve around concern for personal well-being. Homocentric values revolve around concern for other human beings. Ecocentric or biocentric values revolve around concern for the whole ecosystem or biosphere. As an indication for sustainable lifestyle the values should move towards the ecocentric end of the continuum or hierarchy.
