Fifth Graders Study Genetic Mutations at DNALC Laboratory

Earlier in the week, fifth graders spent the day at the Dolan DNA Learning Center of Cold Spring Harbor Laboratory.

The visit was conducted through our partnership with the DNALC for a several weeks' long DNA science unit. While at the Learning Center, the boys completed two rounds of investigations, met a scientist, and explored the Learning Center’s museum.

They learned about DNA mutations and their effects by examining microscopic roundworms and small fruit flies under the microscope, searching for differences in behavior or physical characteristics that could be explained by genetic mutations.

Dr. Molly Hammell, a scientist at the Cold Spring Harbor Laboratory who studies how melanoma spreads, and tests treatments that might help fight the cancer, spoke at length to the boys. She fielded many questions they asked about her research and how she came to be a scientist. Dr. Hammell discussed two genes that often are mutated in melanoma, which tied in nicely to the boys’ current study of genetics.

At the Learning Center's museum, the boys viewed a full-size, 3D printed replica of Otzi, the 5000-year-old ice man who was discovered by skiers in the Alps, and they learned how scientists discerned his age, health, occupation, and travel history using molecular biology.

They were fascinated by Otzi and his story. It is believed that he was shot in the back with an arrow, fell into a crevice and was quickly buried in snow. Our boys offered their own interpretations of what might have happened to him as well, including that he had accidentally stabbed himself with an arrow, or had fallen first and landed on the arrow.

The boys came home with many new ideas and great questions they will explore as they continue their study of DNA with their teachers and DNALC educators.

This unit in Fifth Grade, as well as the partnership with DNALC in Eighth Grade, which involves an original DNA research project, afford our boys the valuable opportunity to interact with and learn in a hands-on way from scientists at the forefront of exciting DNA research. Imagine how inspiring this is for our fifth graders!

OLIVER!

This morning our fifth graders continued a great year-end tradition at Saint David's, The Fifth Grade Musical. The boys performed Oliver! and they were fantastic, providing impressive performances and demonstrating great vocal ability. They have been mastering the dialogue and musical numbers for weeks, and clearly gave it their all. Congratulations to the cast on a job well done, and to their Producers/Teachers James Hubbard and Jamie MacNeille, Director Phyllis Clark, Musical Conductor Jeff Moore, and the Parent Committee of Cynthia Chapman, Susan Kissane, Tara Neumann, Joyce Restituto, and Ann Roberts. Musical theater is alive and well at Saint David's!

Fascinating Art Talk by Michelle Marder Kamhi at Grandparents Event

Yesterday evening, independent scholar and critic Michelle Marder Kamhi ( www.mmkamhi.com ), co-editor with husband Louis Torres of Aristos , an online review of arts; author of Who Says That's Art? A Commonsense View of the Visual Arts ; and grandmother of two Saint David's boys, gave a thought provoking talk on art for our grandparent community. An advocate of objective standards in arts scholarship and criticism, Ms. Kamhi focused her talk on the ways in which art critics such as Clement Greenberg promoted the shift from representational art to abstraction. Kamhi argues that the abstract and post-modern art prevalent today, which often requires explanation by docents in order to be understood, goes against art's purpose. Taking issue with Greenberg's contention that representation is an expendable convention of painting, she quoted the late art critic John Canaday: "Art is the tangible expression of the intangible values that men live by." ...

NE Patriot Tom Brady at Saint David’s

Last night, Saint David’s was honored to have one of the greatest quarterbacks of all time, four time Superbowl champion and three-time MVP winner Tom Brady, as the guest speaker for our Alumni Parents Council Lecture Series. Tom, who is the father of one of our Saint David's boys, addressed a standing-room-only audience in Hyman Hall comprised of our eighth graders, alumni, alumni parents and faculty. Friendly, introspective, witty, and wise, he directed his talk to the delighted eighth graders in the front of the room, and focused on the topic of leadership. “You are the young men and leaders of Saint David’s,” he noted. Tom debunked the perception that leaders are born not made, and credited his leadership abilities to “standing up to and facing fears” and to “cultivating a mental strength,” which he cited as “more important than being physically strong.” He also stressed the importance of working hard, honoring teamwork, believing in oneself and being a good lis...
