What's in a brain? Room 5 finds out!
"What did the hippocampus say during its retirement party?" asked Arpa Ghazarian, one of Mirman School's science teachers. "Thanks for the memories!"
All joking aside, it was pretty serious business in the Lower School science lab this week when both Room 5 classrooms joined Ms. Ghazarian for a lecture and hands-on activity that was completely new to most (we're guessing!) students: dissecting sheep brains.
The brains, which were about the size of an adult's fist and had been preserved in formaldehyde, made their way onto dissection trays after Ms. Ghazarian walked the classes through both short- and long-term memory exercises as well as some diagrams that mapped out exactly what treasures can be found inside the brains.
First, the students familiarized themselves with the feel of the brain, which Ms. Ghazarian likened to tofu. The intrepid scientists then used their probes and scalpels to start getting acquainted. Though there were some moments of squeamishness, overall the students were eager to explore the inner-workings of their specimens, including the functions of dendrites, the corpus collosum, gray and white matter, and more.
