Students of Grade IV yet again proved the power of collaboration. For their third PBL Inquiry, “How do we create a System that provides Safe Drinking Water to all at a Low Cost?”, students were taken back to the era of Jungle book through a song and a video. The video helped teachers create a scenario where Mowgli’s human friend Shanti is visiting him in the jungle and he is trying to collect water from a stream to offer her. The students were put into online and offline groups and challenged with a task to filter the dirty water and make it fit for Shanti to consume. Putting on their thinking caps, students came up with different ideas to design a water filter with bare minimum materials available in the jungle. On 17th December, 2021 students came forward and presented their ideas to their classmates.
