Green Chemistry in the School Laboratory

Summary/Abstract: Despite the great contribution of chemistry, its negative image in society is a serious problem. Green Chemistry (or Sustainable Chemistry) addresses the efficient use of raw materials and waste management and issues related to health, safety and the environment. It offers the opportunity to put ideas of sustainability into school practice. This paper examines the effect of the application of green chemistry in laboratory activities on the study of chemical processes for students in grade 10. For this aim “green” alternatives of traditional experiments on the subject are selected and adapted. The quality and applicability of the experiments and didactic materials are validated through an expert evaluation of 16 teachers. After implementing some of the experiments into the laboratory practices of 70 tenth graders, a survey was conducted with them.The surveyed students gave a high rating to the green attempts: in terms of their: safety, economy, related to everyday life, accessibility, attractiveness. Experimental activities of students lead to their engagement in chemistry classes and Chemistry becomes more interesting, more comprehensible and more accessible to them. The emphasis on green chemistry in laboratory work contributes to the development of environmental awareness and behavior. The attitude of the students towards the subject is improved because they see science in a new, better perspective, as friendly to the environment. It is an effective method of motivating students to study chemistry and influencing their attitudes and emotions towards sustainability and environmental issues.
