What is a Brain?

We brainstormed this question and came up with a definition....these are some of our ideas:

Something that controls every move you make.    (Addie)

It makes you talk and think.     (Louie)

Something that makes you think and act.     (Sophie)

Something that's in your head, protected by a skull.  It's pink, squishy and very delicate.    (Lockie)

It stores your memory.     (Ava)
