Two teams of Sachem High School North student-scientists recently showcased their scientific prowess as they secured top finishes at the 21st Annual Long Island Envirothon on April 30. 

Out of 32 teams participating in the regional competition, Sachem North Team-1 earned a first place finish in oral presentation and first place overall for both Nassau and Suffolk counties. The winning team featured senior Emily Gelardi, juniors Kaya Monolt, Alena Thotam and Caitlin Tucker, and sophomore Catalina Vera, who navigated hands-on tests in five environmental science categories which included aquatics, forestry, wildlife, soils and this year’s current issue, “Agriculture and the Environment: Knowledge and Technology to Feed the World.”   

Additionally, Sachem North Team-2, composed of juniors Anika Banerjee, Miranda Garcia-Cassani and Madison Tutone paired with sophomores Grace McGowan and Andzelika Tislenko, earned second place in Suffolk County. 

Also included in the challenging competition is an oral presentation for which students are given an environmental problem and are required to research the issue, prepare a solution and orally present their results to a panel of judges. The reference materials that students must master for each content area are extensive, and the preparation for the 10-minute, project-based-learning style presentation requires an enormous amount of extracurricular time and commitment.

As first place winners, each team member received $500 and a local field guide and was awarded an all-expenses-paid trip to compete at the New York State Envirothon in Geneva, New York, on May 22 and 23.

Technology Helps Create Connections to Curriculum

Curriculum connections were plentiful for students at Sachem High School North during a recent visit from the Sachem Public Library, as students engaged in several activities utilizing high- and low-tech educational tools.

During science and math classes, students across grade levels experimented with educational technologies that emphasized science, technology, engineering and math. Students used Magical Magnets to create three-dimensional figures, structures and shapes in addition to testing their design abilities using Strawbees and Legos. 

Exploring more complex technologies, students used the Autodesk program to improve their freehand drawing skills and fuel interests in digital art. Additionally, students tried on virtual reality headsets and used iPads to control mBot robots. 

The visit from the public library allowed students to explore current curriculum concepts using a versatile selection of educational materials.   


Annual Internship and Career Connection Opens Doors to Opportunity

Sachem high school students recently explored an eclectic assortment of future opportunities during the second annual Internship and Career Connection hosted at Sachem High School North.

The expansive event featured 28 local businesses and organizations that provided junior and senior students with information on future career and internship opportunities. The long list of groups who participated in the event included the New York Jets, Sachem Public Library, Nichols College, Fashion Institute of Design and Merchandising, Seeds of Achievement, the Boy Scouts of America, Splish Splash, RE/MAX Real Estate, Techworks, Civil Air Patrol, the United States Marine Corps, Long Island Community Hospital, the United States Army, RG Financial Investment Solutions, the United States Navy, Ronald McDonald House, Bob’s Stores, National Tax and Financial Services, New York City Police Department, American Pools, Keiser University, RFC Fence, Suffolk County Police Department, Accucare Health, the National Guard, First National Bank, FDNY and the Guitar Guy.

During the event, which was organized by the Sachem Business Department, hundreds of students conversed with business representatives to further their knowledge in their areas of interest. Assisting with the daylong event were a group of Sachem High School North business students, who arranged tables and escorted the representatives to the gymnasium. 

Once the event had concluded, business teacher William Ward reflected on how it impacted the students. "The beautiful thing about having success as a business teacher and creating an event with students, colleagues and professionals is that the impact, like waves, continues to manifest and pay dividends further than the eye can see."

Sachem Hosts Conference Led by Prestigious Geneticist

Students and staff from multiple Long Island school districts converged on the Sachem High School North auditorium for a genetics program presented by nationally renowned genetics educator Dr. Sam Rhine.

In its 14th year at Sachem High School North, the one-day genetics conference designed for community members, high school students and their teachers provided key insight for students interested in careers in medicine, biological research or other life science careers.

This year’s conference spanned topics that included the genetics of common single-gene disorders such as cystic fibrosis and sickle cell anemia, to more complicated polygenic conditions, such as obesity, cancer, arthritis and Alzheimer’s disease. In addition, recent advances within the field of genetics and information regarding the widely popular ancestry testing, currently directly available to consumers, was also discussed.

Additionally, Amy and a partner were selected to advance to the second round of the prestigious Long Island Science and Engineering Fair. 

Approximately 1.6 million juniors from high schools across the country entered the 2019 National Merit Scholarship program by taking the Preliminary SAT/National Merit Scholarship Qualifying Test. The 15,000 finalists now continue in the competition for some 7,500 National Merit Scholarships worth more than $31 million. Those who have been selected as Merit Scholarship winners will be announced between March and June.
