On the 15th of August, the annual Eskom Expo for Young Scientists regional competition took place at Walter Sisulu University, showcasing student scientific research and engineering projects from across the region. Two learners represented Port Rex Technical High School: Grade 11 learner Milani Mjiji and Grade 10 learner Ahluma Vumazonke.
Milani entered the Chemistry and Biochemistry category with a comparative study evaluating the water purification properties of moringa seeds against pineapple peels. The project reflected two years of rigorous research and development, conducted under the dedicated mentorship and guidance of her Physical Sciences teacher, Mrs Daisy John.
Ahluma Vumazonke competed in the Energy category, designing and presenting a functional model of a power-generating trailer that converts kinetic energy into usable electricity. Applying principles from his Electrical Technology coursework, Ahluma developed the prototype to address the widespread challenge of affordable electricity access across South African communities, supported by mentors Mrs Lereen Goosen and Mr Stuart Harding.
Both learners achieved exceptional results, each earning a gold medal as well as special recognition awards for the top projects in their respective categories. Capping off her success, Milani was awarded a prestigious bursary from Rhodes University to pursue any degree within the Faculty of Science.
Bolstered by these individual triumphs, Port Rex Technical High School concluded the event by being awarded as the top-performing school in the region.
