30 Amazing Facts in Science (Download link below)

A : The brain is an organ inside the skull.It forms only about two per cent of our body weight, but it controls our feelings, movement, skills and every function necessary to live. The human brain is divided into three major parts; the cerebrum, the cerebellum,and the brainstem. The cerebrum gives us intelligence. It makes up 85 per cent of the brain and operates voluntary muscles that we have control over. The cerebrum is the area of the brain that allows us to dance, jump or solve puzzles. It also stores information, which we call memory. The cerebellum or ‘little brain’ is below the cerebrum and is just one-eighth of the size of it. The cerebellum controls balance and tells the muscles how to move. The brainstem connects the rest of the brain to the spinal cord, which runs down the neck and back. The brainstem controls involuntary muscles that work without us thinking about it, like the heart, the lungs and the stomach.
