While ozone in the stratosphere protects us from the harmful effects of ultraviolet radiation (UV), ozone at ground level causes several damages, destroying plants, causing respiratory diseases and irritation in the human eyes. The main objective of the present work was to simulate an atmospheric ambient containing high concentration of ozone (O3 ), which is one of the substances generated during a photochemical smog event. This experiment can be reproduced at school where students will be able to observe the harmful effects of ozone in plants during a period of several days under O3 exposition. The results of the experiment can be approached with an interdisciplinary context and several other environmental issues can be worked with the active participation of the students.
