The International Day for the preservation of the ozone layer is observed on 16th September every year since 1995. At Presidium, students of Grade- 3 celebrated World Ozone Day with the view of creating awareness and sensitizing the students on the importance of the Ozone layer. Students actively participated by wearing green clothes, making colourful posters, and shouting slogans like "Earth without ozone, is like a house without a roof." Through the virtual assembly, the students were given the importance of the Ozone layer and its impact on Earth's forms of life. Presidians highlighted the importance of the day and students' role in contributing to protecting and preventing the Ozone layer from depletion. Further, to mark the day's significance, pupils were involved in various activities such as slogan writing, Speeches, PowerPoint presentation, Quiz, etc. Our young learners designed amazing posters in which the simple ways of protecting the ozone layer were depicted.
