Sachem Leads the Way in Competitive ESports

For the Gamers Club at Sachem High School North, a tri-tournament competition this June for the game “Overwatch” provided students with a chance to compete in person against gamers from other school districts on Long Island.

Held on June 6 at Waypoint Gaming in Garden City, the tournament is the first of many where Sachem North will be competing as part of the High School Esports League. The tournament, which also featured teams from Bay Shore and St. Anthony’s high schools, allowed the student gamers to compete in the same area rather than over the internet. 

At the completion of the tournament, the Sachem North gamers tied for first place with the team from Bay Shore High School.

Sachem Students Attend Barcode Long Island Symposium

This June, four Sachem High School North students attended the annual Barcode Long Island Symposium led by Cold Spring Harbor Laboratory’s DNA Learning Center, in collaboration with Stony Brook University, Brookhaven National Laboratory and the American Museum of Natural History.

Barcode Long Island uses DNA barcoding to explore, document and track biodiversity on and around Long Island through experiments led by student research teams. Kaya Manolt, Caitlin Tucker and Madison Tutone developed a research project titled “The effect of vegetated buffer zones on aquatic biodiversity,” comparing both water quality and presence of indicator species at two local ponds. Nistha Boghra researched “The biodiversity of a restored estuary” by sampling water quality and organisms at Sunken Meadow State Park. As part of the symposium, each student presented a poster displaying their research and interacted with peers, educators and world-renowned scientists. Among the notable guests was Dr. James Watson, famous Nobel Prize laureate, molecular biologist, geneticist and zoologist, best known for being a co-discoverer of the structure of DNA in 1953.

To begin their rigorous research, the students first dedicated countless hours to refine the design of their projects before performing the procedures of professional scientists. To move forward with their research, the student scientists needed to meet the strict guidelines set by Barcode Long Island and receive approval from Cold Spring Harbor Laboratory’s DNA Learning Center staff scientists. 

The students collected up to 20 organisms from water samples for each project. Next, with guidance from Sachem High School North science teacher Monica Marlowe, Barcode Long Island educators, scientists from Brookhaven National Laboratory in 2017 and Stony Brook University in 2018, they worked to isolate and amplify the DNA of each organism to positively identify each species. Out of the seven viable samples that were submitted for sequencing, two came back with novel sequence data when aligned with available data on the genetic sequence database GenBank. The novel sequence data is significant because no other scientist has yet sequenced these organisms in the cytochrome oxidase I barcode region and these students will be credited with the publication of this sequence information.

“Caitlin, Kaya, Madison and Nistha have collectively dedicated an impressive amount of extracurricular time and energy in the completion of their projects and the pursuit of scientific advancement,” Marlowe said.

In March of this year, collectively, the Sachem scientists sequenced another 26 samples, resulting in seven additional novel sequences to be published in GenBank.

The Sachem science research department recently hosted its annual symposium at High School North in celebration of the tireless work displayed by the student-scientists throughout the school year. 

The symposium served as an opportunity to honor the science research students from grades 9- 12 for their continued dedication to science and their progressive research efforts. To begin the event, guest speakers Angelica Franqueiro and Daniel Waxman, seniors at Sachem High School North and East respectively, presented their research to an auditorium full of family and fellow research students. Next, Samantha Meadows, a Ph.D. candidate in neuroscience at Weill Cornell Medicine and a High School East alumnus, spoke about how Sachem shaped the beginning years of her academic experience, the importance of goal setting and how to effectively plan for the future.

“Science research is an important area of your academics because it allows you to fuel your own learning,” Meadows told the student-filled audience. “The power of your research is that you can do something that can change the world.” 

As the symposium concluded, 10 graduating seniors were recognized for their accomplishments in the science research program, and all attendees were welcomed to view posterboards of the students’ work on display in the gymnasium.

Family, friends and distinguished guests cheered as a sea of smiling graduates adorned in black caps and gowns filed onto the football field for the annual commencement ceremony honoring the Sachem High School North Class of 2018. 

As the ceremony began, members of the select choir beautifully performed “The Star-Spangled Banner” before High School North Principal Patricia Trombetta welcomed the Class of 2018 with a powerful speech that spoke to her belief in the graduates’ abilities to succeed. 

“There are going to be challenges and obstacles along the way, but I have the utmost confidence that you are prepared and able to accomplish anything you put your mind to,” Trombetta said. “Follow your dreams and let the world know that you are on your way.”

Continuing the ceremony, Superintendent of Schools Dr. Kenneth Graham delivered a speech on the value of the connections students have made during their experience in the Sachem Central School District and the tremendous accomplishments they have made thus far. 

“Graduates, we followed you as a class and watched with great pride as you have accomplished so much. The Class of 2018 should be incredibly proud of all they have done while here at Sachem,” he said. 

During an inspiring speech that followed, Class of 2018 valedictorian Abigail Bandl echoed her confidence in her fellow graduates and herself to accomplish great things as they begin the next chapter of their young lives. 

“One thing that I can say for sure is that our time at Sachem has prepared us for what lies ahead,” Abigail said. “All of us sitting here today are fully equipped with the knowledge and skills necessary to tackle the world and make an impact.”

As the ceremony came to a close, students moved their tassels from right to left, signifying their graduation. With pastel blue skies above, students threw their caps into the air with a celebratory cheer as they closed the chapter on their experience as students in the Sachem Central School District.
