K1 children of Orchids The International School-Thane, the most famous CBSE school in Kalwa had the topic ‘Elements of Life’ as a part of their syllabus, in which ‘Water’ is listed as one of the most important elements. They were taught the sources of water and the process through which water reaches their homes. In order to provide a practical understanding of the topic, children were taken to the water purification plant ‘Zaraana’ at Manpada, Thane. Children were shown the equipment that is used in water purification and the purification process – right from extracting water from the ground and purification process (RO process) and bottling. The process interested the children and they were able to relate it to their lesson.
