Sienna Spurling learnt about embryonic stem cell research in biology class at the Bermuda High School.

The 14-year-old was intrigued by the controversy. Embryonic stem cells are the building blocks of the body and can become any kind of cell. Scientists want to use them to research a range of diseases but harvesting them kills the embryo.

“There is a global debate with so many different views political, religious, and scientific,” she said. “It is very similar to the abortion debate in that there are opposing pro-life and pro-choice camps.”

Two thousand words on the topic won her a distinction in the prestigious John Locke Institute 2023 Global Essay Competition, based in Oxford, England.

Her classmate, Joy Yammine, also received a distinction in the Under-15 category; 13-year-old Aditi Varwandkar was shortlisted.

Each year 19,000 students from around the world enter the competition; 100 are shortlisted. Three winners are chosen; the top 15 per cent receive distinctions.

Essays were judged on the writer’s understanding of the relevant material, the use of evidence, quality of argumentation, originality, structure, writing style and persuasive force.

The contest was named for the English philosopher John Locke and asks students 18 and under to ponder questions such as why John Locke is considered the father of liberalism; why safety is more important than fun; and if you had $10 billion, how would you use it to make the world better.

Sienna and Joy wrote in response to the question, what is something important that people are often wrong about?

Joy took a philosophical angle, making her essay about happiness.

“It is something I have been interested in for a while,” she said. “My essay was about how people pursue happiness. Often happiness is looked at as a destination, when it is really a journey. It is not a tangible feeling. You do not know if you have reached happiness.”

The 14-year-old looked at the correlation between money and happiness.

“Beyond the point where all your basic needs are met and you are comfortable with food and shelter, there is no correlation with happiness,” she said. “Money does not make you any more happy.

“In my conclusion, I said that if you want to pursue happiness over a long period of time, you first need to find fulfilment, and contentment.”

Aditi tackled the question what, if anything, do parents owe their children?

“My take on it was that a parent owes their child the best life possible and the tools to succeed in life,” she said.

The teenager discussed central things that children need, such as food, water, clothing, and love. She felt they also needed practice for the real world and tools such as education.

“All children deserve a parent but not all parents deserve a child,” Aditi said. “It’s just about making sure that you’re in the position where you can give your child that better life.”

Their prize was a weekend seminar at Oxford University and admission to a prizegiving reception and gala dinner there.

The girls were scheduled to be in England for the weekend of September 16, but Hurricane Lee intervened, brushing past Bermuda with high waves and power cuts.

“Our flights were pushed back,” said Sienna. “Joy and I arrived a day late.”

That meant they missed the gala dinner and workshops arranged for the Saturday morning.

“At least we got to go to most of the seminars and the main award ceremony on Saturday evening at the Sheldonian Theatre,” Joy said. “That was really great.”

The awards ceremony was very formal.

“They don’t make you walk across the stage to receive your certificate [but] they call your name,” Sienna said. “It is very exciting to see so many people from around the world.”

It was her second time attending after she was shortlisted last year for an essay on taxes.

“We were told we were in the room where students take exams,” Sienna said. “There was a giant clock on the wall. The instructor told us that if we went to Oxford this would be one of the most stressful places for us.”

Seminar topics covered everything from essay writing, to tips on the United Kingdom university application process, to application to Oxford and Cambridge. The winning students also shared their essays.

“Getting into Oxford or Cambridge is not my main goal but that was very interesting,” Sienna said. “There were lots of people at the awards ceremony. It was good that BHS could be represented.”

Students took part in the competition with the help of BHS global politics and history teacher Amy Dingley-Jones.

“I’ve directed students to the John Locke essay prize for the last eight or nine years while working in different countries,” she said.

She added that the competition was a great opportunity for students to explore subjects they were interested in.

“They have to cut it down and structure it in a way that is readable but also different to the other thousands of entries,” Ms Dingley-Jones said. “They also have to give references. It is really impressive that they have been not only shortlisted but received distinctions, as well.”

Reading and writing about embryonic stem cell research cemented Sienna’s fascination with science. “I might go into biology or medicine,” she said.

Joy would like to take courses in psychology. “As a career, I might go into medicine or dentistry,” she said.

Meanwhile, Aditi was also considering psychology, or law.
