Students of class 6th presented a working model on ‘The steps of water purification’ in front of the students in the morning assembly. The model consisted of four levels containing different elements to aid the purification of water namely big stones for larger-sized impurities, small stones for small impurities, charcoal for dissolved impurities and cotton for absorption of final impurities. The model was observed to be a very interesting and creative way to teach the students about the methods and significance of purification.
