For Grade 8 learner Denica Swartz, participating in Eskom Expo began four years ago with a fascination for research and discovery. In 2026, that journey culminated in her being named the Top Junior Scientist at the 46th Eskom Expo International Science Fair (ISF), where she received a R50 000 cash prize.
The Eunice High School learner, representing the Bloemfontein Region, also received a Gold medal and an FFS Refiners Award, earning an iPad for the practical application of chemical engineering principles in her research.
Swartz describes herself as naturally curious and particularly interested in how science can solve real-world problems. Her journey with Eskom Expo began long before her latest achievement. After seeing other young scientists participating in the programme, she knew she wanted to experience it herself.
“The first time I saw other learners taking part in Expo, I thought it looked really interesting and something I would love to be part of one day,” she recalled. “Once I took part myself in Grade 4, I really enjoyed the experience of doing research and learning new things.”
Four years later, Swartz found herself among young scientists from South Africa and abroad at the ISF. One highlight was not simply competing, but interacting with other participants who shared her enthusiasm for research.
“One of my most memorable parts of ISF was being surrounded by so many young people who are passionate about science and innovation,” she said. “I really enjoyed talking to other learners about their projects.”
That experience became even more memorable when Swartz was announced as the 2026 Top Junior Scientist. “Winning was an incredibly special and unexpected moment for me,” she said. “I felt proud, grateful and honestly a little overwhelmed because I knew how much work had gone into the project.”
For Swartz, the recognition represents far more than the awards she took home. “The award isn’t just about winning. It represents the journey and the challenges I overcame to get so far,” she said.
Her passion for science and innovation has been strongly influenced by her father, who introduced her to different areas of science from a young age.
“I think my passion for STEMI mostly comes from my dad,” she said. “He was the one who introduced me to more parts of science and innovation. That’s when I became more passionate about science.”
Despite her growing achievements in science, Swartz believes having interests outside research is equally important. Away from STEMI, she enjoys dance, which provides a different creative outlet and balance in her life.
“I think having interests outside of science is important because it gives me balance and allows me to develop different skills,” she said.
Having progressed from her first Eskom Expo experience in Grade 4 to becoming the Top Junior Scientist in Grade 8, Swartz encourages other young scientists not to begin their research journey with awards as their primary motivation.
“My biggest advice would be to choose a project that you genuinely care about. Don’t do a project just because you think it will win,” she said.
Instead, she believes young scientists should remain curious and embrace unexpected results as part of the research process.
“Be curious, don’t be afraid of results that aren’t what you expected, and learn from every step of your journey,” Swartz said. “Most importantly, believe in your research and enjoy the journey.”
