Orchids The International School-Koparkhairane, one of the leading CBSE schools around Vashi, places great emphasis on the importance of experimental and investigative learning. Concepts across subjects are taught through practical approaches. Grade 5 students had the chapter ‘Air & Water’ in their Science curriculum. The teacher conducted various experiments to enable a practical understanding of the topics – sedimentation, decantation, filtration etc., during the Science class. Students got an opportunity to observe, explore and understand these topics through these practical experiments.
