Siweya was among three more learners who were showcasing their scientific research at the grand final of the Indonesia International Science, Technology and Engineering Competition (ISTEC) in Bali recently. He received a silver medal for his research project, “Does weight affect piezoelectric output on shoe insoles”.

Siweya used three tests to measure the voltage produced and the durability of the shoe sole to find a sustainable power source to keep the lights on. He said: “I was in disbelief when I heard my
name being called to receive a silver medal. A surge of joy flowed through me, and I was so grateful.

“Taking part in the competition was an educational experience because, in the engineering category, learners could incorporate computer science projects, so I learned a lot. I will surely do the same on my next Eskom Expo project,” he said. The other three learners were Luke Boswell from Port Elizabeth who received a gold medal for his project, Matthew Crouch from Stellenbosch also received a gold medal for his project, and Zariah Parker from Cape Town who received a silver medal.

Siweya’s Physical Science teacher and mentor at KLC, Mathildah Musingarimi, told the Herald that she is proud of his achievements. “It gives me great pleasure to have been Ndzhaka’s mentor to the point of him going international. He was a pleasure to work with. His focus and zeal helped him, and I wish him all the best in whatever he does. Well done Ndzhaka and keep shining,” she concluded.
