The children learned about the ozone layer and its protection qualities. The main goal of the organizers was to inform the pupils of primary school about ozone, the problems concerned with preservation of the ozone layer and precautionary measures against the harmful influence of ultra-violet emanation.

Detailed talk, posters about environment, demonstration of the film ‘Ozzi Ozone’ with further discussion of it, questioning on understanding of this film allowed children to gain useful practical skill of being in the sun.
