In this study, 10th-grade students` conceptions concerning acid rain, ozone layer, and greenhouse effect were investigated. A conception test that asked to explain about the three concepts and the relationships among them was administered to 137 students. Analysis of their responses indicated that students had lack of understanding about the definition of acid rain, the difference between greenhouse effect and global warming, and how to prevent the increase in greenhouse effect. They also confused ozone layer with greenhouse effect. Many students thought that there were causal relationships among the increase of acid rain, the destruction of ozone layer, and the increase in greenhouse effect.
