The Wellington School in Upper Arlington welcomed 115 new students when classes resumed Aug. 21, swelling enrollment to one of the largest in school history.

Head of School Robert Brisk said this year's enrollment is 650 students.

"This created a need for an additional kindergarten class as well as wait pools for multiple grade levels," he said.

The school held a Back to School Sundae ice cream social Aug. 18, during which families could meet teachers and students could check out new classrooms.

Brisk said Wellington will "proudly continue its commitment to foster fearless learning."

A new Upper School science curriculum will be implemented this year that includes research opportunities through the Wellington Research Institute.

"Our Head of Upper School, Dr. Jeff Terwin, will officially open the Wellington Research Institute by teaching marine biology," Brisk said.

Terwin said the school will debut four new science courses: ecology of Ohio, infectious disease microbiology, atmospheric chemistry and marine biology.

"Marine biology figures to be a popular selection, with its SCUBA training and optional SCUBA certification and trip to the Grand Caymans," Terwin said. "These trimester courses and the yearlong upper-level courses will all count toward the science graduation requirements."

He said another new course on independent science research will lead students through the development and execution of an authentic research investigation with an outside mentor.

"With authentic research comes the opportunity to pursue publication, a prospect which is very exciting," he said.

"We have plans in place to expand this research-based approach as we continue to develop the Wellington Research Institute, where students will have the opportunity to maintain ongoing research, develop publications and interact with scientists and research organizations beyond the Wellington campus."

Terwin said science teachers decided the usual sequence of biology in ninth grade and chemistry in 10th grade did not adequately prepare students to study or to pursue research in the scientific fields of their choice.

He said the sequence limited students' exposure to physics classes until 11th grade.

"We have developed a new mixed course that will provide a solid grounding in biology, chemistry and physics," he said.

He said freshmen in the mixed course will have a new science faculty member each trimester to guide them through scientific concepts and research skills.

Brisk said Wellington's Enrichment Series this school year will present a wide scope of topics for parents and students "to learn and discuss how we as a community raise resilient children in an ever-changing world."

One of the featured speakers will be Yong Zhao, an internationally known scholar and author, who will discuss essential elements of entrepreneur-oriented education.

"The start of every new school year in Wellington is always exciting, with the vast potential for each student in these halls," Brisk said. "It is both our duty and our reward as educators at the Wellington School to prepare students not just for the days we can see ahead, but for the ones we can't yet imagine."
