Abstract
An ozone depletion model experimental device was developed to deepen understanding of students for the issue of ozone depletion and to give them concern. Both of “Instruction manual of the device” and “Text book about the issue of ozone depletion and the model experimental device” were edited. The experiment and an illustration of ozone depletion mechanism were taken up in classes of environmental education in elementary schools, junior high schools and senior high schools, questionnaires to students were carried out before and after the class. The questionnaire result of the student who carried out to the experiment, and the student to whom ozone layer depletion was explained using figures was compared, and the effect of the experiment was proved. The manual and textbook were improved by the questionnaire result of a teacher. Furthermore, the safety of the experimental device was examined and the important matter when advancing an experiment was also shown.
