Two young Pretoria learners have achieved an unprecedented milestone in South African science fair history, proving that innovation knows no age limit. Gustav Heesen of Afrikaans Hoër Seunskool and Johan Vorster of Pretoria Boys High School, both formerly from Laerskool Anton van Wouw, made history in 2025 when they became the
first Grade 7 learners in 39 years to be named Overall Winners of the Gauteng-North iMBEWU Science Fair. Competing against learners up to Grade 12 level, the pair also secured gold in the Artificial Intelligence (AI) category, outperforming projects across multiple grades.
Their award-winning project focused on developing an accessible, AI-driven solution to support teachers in overcrowded classrooms. By addressing a real and pressing challenge in South African education, their work demonstrated both technical capability and meaningful social impact. The project stood out for its practical application of artificial intelligence and its potential to improve learning environments in resource-constrained settings.
Their success at regional level marked a historic moment for the iMBEWU Science Fair and highlighted the growing importance of STEM innovation among younger learners.
Their journey continued in January 2026, when they competed at the National iMBEWU SA-YESS (South African Youth Environmental and Science Symposium). Once again, they
excelled, achieving Gold and Second Runner-Up overall among the country’s top young scientists.
As a result of their exceptional performance, Johan and Gustav have been selected to represent both South Africa and the iMBEWU Science Fair internationally at the prestigious Genius Olympiad, to be held in Rochester, New York, in June 2026. This global competition brings together outstanding learners from around the world to showcase innovative solutions.
The opportunity represents more than just competition. It allows them to represent South Africa internationally, engage with global peers, learn from leading young scientists, and bring valuable knowledge back to their communities. However, participation comes at a high cost. Expenses such as international travel, accommodation, registration, visas, and insurance present a financial challenge.
