Treatment of waste generated as a result of human activity is essential for our sustainability. Hence, it is imperative to know the nature of waste materials around us. Waste materials primarily are of two kinds - Biodegradable and Non-biodegradable waste. Students of Grade 4 learned about the segregation of Biodegradable and Non-biodegradable waste under the theme -Waste Management. The students presented a collage wherein they learned that the sorting of waste materials as biodegradable and non-biodegradable could help in reducing the menace of waste management. The purpose of the enrichment activity was to generate awareness among the students towards environmental protection. They were also made aware of how we can handle any environmental issue as an individual and at the community level.
