After reading about brain, Kabir and Arjun made a model of their brain (copied it from the book) and labeled it as seen in the photos below.
Also, we did an experiment which shows that the fluid around our brain protects our brain. We put an egg (depicting our brain) in a tupperware and kids shook it. The egg broke.
Then, we took another egg, put it in a tupperware with water. It took violent shaking to break the egg. So, the fluid protected the egg. Similarly, the fluid around our brain prevents it from breaking in our skull.
