Grade 1 scientists performed their very first dissection last week as a culmination of their adaptations unit. The girls dissected a squid and observed the beak, ink sac, tentacles with suction cups, chromatophores for camouflage, fins, and siphon. They even used a part of squid anatomy called the pen to write with the ink. Squid pens, or gladii, are the vestigial internal shell of squid. They’re used primarily to support squids’ muscular tissues and organs. The flexible pen allows for jet propulsive swimming. Squeals of joy filled the room as several young scientists exclaimed, “this is the best day of my life!”
Another group of impressive young scientists completed their cow eye dissection last week. As part of the learning, we had an incredibly engaging guest speaker, Dr. Krista Ramonas. The girls were so inspired by her presentation. They asked many thought-provoking questions and approached the dissection with the maturity and interest of true scientists. They said their favorite parts were the tapetum lucidum, optic nerve, vitreous humor, and lens.
