Inspiring hope: Young cancer survivor shines at Eskom Expo International Science Fair

Representing the Stellenbosch Region at the 45th Eskom Expo International Science Fair (ISF), 13-year old Zachary “Zhara” du Toit from Laerskool Lochnerhof in Strand stood out not only for her innovative thinking, but also for her incredible personal journey of resilience and hope.

Held at the Emperors Palace Convention Centre in Kempton Park, the 2025 Eskom Expo ISF brought together hundreds of brilliant young minds from across South Africa and several international countries. The event celebrated innovation and problem-solving in science, technology, engineering, mathematics, and innovation (STEMI). 

Cancer survivor, Zhara was awarded the first place SAICE Environmental Engineering Division Award, winning R7 000 and a Silver medal for the research project, “Designing a Reusable Crate for Sustainable Grocery Delivery”.

Zhara’s path to the ISF was not an easy one. 

“Two years ago, I faced a very difficult battle with cancer, but that experience taught me to never give up and to always stay hopeful,” she said. “It made me realise how powerful determination and positive thinking can be, and that I should make the most of every opportunity.”

Zhara first became involved in Eskom Expo when her school introduced a science project based on the Expo format. Her creativity and passion soon earned her a place at the Stellenbosch Regional Science Fair, and then the opportunity to compete at the Eskom Expo International Science Fair.

“It has been such an exciting journey where I’ve learnt so much,” she said.

For Zhara, the highlight of the ISF was meeting like-minded young scientists from across the country and beyond. 

“The best part of the ISF for me was meeting so many wonderful children from all over. I didn’t know anyone before arriving, but by the end of the week I had made so many new friends. We laughed a lot and supported each other. Those friendships and memories are what made the experience truly special for me,” she said.

On her first place win, Zhara said: “Just a few years ago, I was fighting for my life and missed my entire Grade 5 year of school while going through chemotherapy, radiation, and several operations. Standing on that stage, I felt so proud and deeply blessed, realising how far I’ve come. It meant so much more than just a medal, it was a symbol of hope and strength,” 

Outside of science, Zhara’s heart shines through in her many creative pursuits. She loves art, drama, and public speaking, and she channels her compassion into her project, “Zhara’s Little Lambs”, which supports children undergoing cancer treatment.

“The lambs are lovingly handmade by people from all over South Africa, and so far, we’ve been able to hand out more than 5 000 lambs to children in hospitals and treatment centres across the country,” she explained. “Each lamb is a small symbol of love, courage, and hope.” 

To other young scientists embarking on their own Eskom Expo journeys, Zhara offered heartfelt advice: “Choose a topic you really enjoy, it makes everything more fun. Believe in your idea and don’t give up, even if things don’t work out the first time. Be proud of yourself and just do your best. And if you ever get the chance to go to the ISF, grab it with both arms, it’s a life-changing experience,” she said.
