PYP 5 Students are doing a unit under the trans-disciplinary theme ‘Who We Are’, and the central idea is ‘Health of our body and mind affects our well being’. Students were given case study related to different systems and they had to find the systems, organs associated with the system, how these systems are interconnected and the role of these systems in the well being of an individual. Students made models to display their understanding of the body systems. The models were realistic and their explanation very appropriate. Their enthusiasm shown through out the process was appreciable.
