Younger innovators earn huge prizes at Eskom Expo International Science Fair

Friday, 10 October 2025: The 2025 Eskom Expo International Science Fair (ISF) ended on a excessive observe as excellent younger scientists have been rewarded with beneficiant money prizes for his or her rigorous and revolutionary analysis initiatives.

The honest, held on the Convention Centre at Emperors Palace in Kempton Park from 6 to 10 October 2025, introduced collectively the brightest younger scientists from South Africa, Lesotho, Namibia, Zimbabwe, Ireland, India and Russia.

The 2025 Top Senior Scientist, successful a R100,000 money prize, was Christopher May from Otto du Plessis High School, representing the Port Elizabeth Region with the analysis challenge, “Differential Geometric Modelling of Sound Signals and Ultrasound Imaging”. The Grade 12 learner was chosen because the Top Senior Scientist by a panel of Chief Judges who have been impressed along with his sound reasoning, logical arguments, and grasp of complicated arithmetic ideas. May designed a technique to analyse the properties of sound utilizing differential geometry. He created a geometrical mannequin of a sound wave and thereafter utilized differentiation methods to analyse its properties. He then went on to use this methodology to ultrasound imaging the place he efficiently enhanced options comparable to delicate edges and the textures of anatomical constructions. This resulted in enhanced medical imaging and improved diagnostic accuracy. May’s analysis highlights the worth of arithmetic as a device to enhance well being care.   

Khushi Lall from Tyger Valley College, representing the Northern Gauteng Region with the analysis challenge, “Garlic: Nature’s Secret to Food Preservation”, was the 2025 Top Junior Scientist recipient, successful a R75,000 money prize. Food preservation has change into a problem globally due to the rise of resistant microbes. This was the motivation behind Lall’s analysis challenge. The Grade 9 learner impressed the Chief Judges along with her outstanding understanding of micro organism comparable to Staphylococcus aureus and her distinctive precision when executing laboratory methods. According to the Chief Judges, such scientific investigative expertise mixed with reasoning and logical considering, is the mark of a scientist within the making.  

Lethabo Kgwete from Moleshatlou Secondary School, representing the Capricorn Region with the analysis challenge “The Effect of Livestock Green Compost Tea”, was awarded Top Development School and acquired a money prize of R75,000. The Grade 11 learner investigated the impact of compost on crop yield. Motivated by the challenges confronted by small scale farmers in rural areas comparable to entry to reasonably priced and sustainable fertilisers, Kgwete developed a cheap and eco-friendly compost referred to as the Livestock Green Compost Tea. This Compost tea was ready by combining fruit peels, dry grass, leaf litter, water, wooden ash, eggshells, and different natural matter in a steeping container. The combination was brewed for a number of days, producing a nutrient-rich liquid. The handled crops (tomatoes, spinach, and onions) persistently confirmed larger top will increase and quicker total development. Lethabo’s analysis holds a lot promise for growing crop yield via sustainable inexperienced fertilisers.

Eskom Development Foundation Acting Chief Executive Officer, Mologadi Motshele, stated: “Eskom is incredibly proud of the young scientists who have participated in the Eskom Expo initiative this year, gaining valuable knowledge, skills, and insights as they explore the dynamic fields of science, technology, engineering, mathematics, and innovation (STEMI).”

“Each year, thousands of learners benefit from Eskom Expo, gaining access to opportunities that would otherwise be out of their reach. We encourage other like-minded school learners to take an interest in this initiative and consider pursuing careers in STEMI fields. By doing so, they can become the architects of a brighter and more prosperous South Africa for future generations. Over time, Eskom’s sustained support has not only empowered individual learners but has also strengthened the nation’s future skills base, driving transformation and excellence in science education.”

A complete of 30 Gold, 77 Silver and 131 Bronze medals have been awarded on the Grand Awards ceremony, whereas the a lot sought-after alternative to characterize South Africa at outstanding worldwide science gala’s in Taiwan, Tunisia, China, Indonesia, the USA, and Türkiye was awarded to deserving learners with the assistance of assorted long-standing sponsors of the Eskom Expo. These will likely be introduced within the coming months.

Eskom Expo Executive Director, Parthy Chetty, stated, “We extend our heartfelt congratulations to the brilliant winners of the International Science Fair. Your ingenuity, perseverance and passion for discovery inspire us all. This achievement is not only a celebration of scientific excellence but a powerful reminder of what’s possible when curiosity meets opportunity. To students everywhere: let this be your spark. STEM subjects open doors to solving global challenges, shaping the future, and making a lasting impact. Whether in labs, classrooms, or communities, your ideas matter. Keep asking questions, keep exploring and know that your journey in science starts now.”
