Day 4 research

We have found many interesting facts about the human brain like the skin of the brain weighing twice as much as our brain.Our brain has a white and grey matter. We have 60% white matter and 40% grey matter.I also found out that our brain at birth was almost the same size as an adult's brain. Our brain will stop shrinking when we reach the age of 18.Another amazing fact that we found out was that our brain uses 20% of our oxygen.our project is going well we will begin designing it tomorrow.
