On November 9, Peri Morenz’s 1B biology class dissected cephalopods as part of a unit lab. Students learned about squid reproduction, gender, organs, and functions. They were also given the opportunity to write notes out of squid ink while utilizing other parts of the body.
With the accelerated learning environment and fast-paced classes, the science department has very little time to complete all the desired labs otherwise planned for the curriculum. However, the students were quite keen on being given the time to dissect and explore the function of Teuthid, the scientific name for squid.
The dissection started with determining the squid’s biological sex and counting the number of tentacles and arms. Students were then asked to cut open the main body cavity and explore the insides, as well as pull out the beak, which is the animal’s sharp eating mouth.
Devon Jones, grade 11, was asked what he learned most about the Animalia unit while completing this dissection.
“I enjoyed learning what squid eat and how they eat,” said Jones. “It was fun doing a hands-on activity because I learned, first hand, what real life body parts of the animal are, and how they work with other organisms and their environment.”
Students were then asked to pull out the ink sac, cut it open, and write with it. The majority of the class was able to get a few words to a couple sentences down, taking several minutes for a few characters because the ink ran out quite quickly.
To conclude the dissection, the class was given further investigation questions and explorations to learn more about the lives of cephalopods. Students were grateful for the break from long classes and strict routines of everyday note taking for the chance to have fun with a real-life specimen. Morenz’s class looks forward to further labs before the quarter is over, and encourages new Gleneagle students to take biology in their junior and senior years.
