Sara, Fantastic question! I found the following information on a web site called "Neursocience for Kids", which is maintained by Eric H. Chudler, Ph.D., at the University of Washington. This is a great place to find information related to the brain. It has a lot of cool information, pictures and games. The main web address is: http://faculty.washington.edu/chudler/neurok.html The address for the brain weight facts is: http://faculty.washington.edu/chudler/facts.html The average brain weight of an adult human is 1,300 - 1,400 grams (about 3 pounds). The average brain weight of a newborn human is 350 - 400 grams.
