Grade 5 students of Orchids The International School – Koparkhairane, a leading CBSE school around Airoli, had a lesson on the ‘Solar system’ in Science. An activity was conducted in the classroom in which students depicted the structure of Earth using clay. They made a small ball with one colour clay and then used two other layers of colour to depict the layers. They then cut through the ball and were explained the structure of Earth- crust, mantle and core. Students were excited to observe their creations and were able to relate it with their lesson.
