The Centre for Mineral Biogeochemistry (CMBG) at the University of the Free State’s (UFS) support and partnership of the Tritech National Science and Technology Fair reached new heights this year with the event set to be featured in a new television series.

CMBG has been a proud sponsor and partner of the Tritech National Science and Technology Fair for the past four years. Established in 2008, Tritech is a renowned competition that allows Grade 7 to Grade 12 learners from across South Africa to showcase their research abilities. The Tritech National Science Competition serves as a beacon of opportunity for young minds, fostering their passion for scientific exploration and igniting their curiosity. It is designed to enhance scientific literacy, encourage innovation, and nurture the next generation of scientists and inventors.

“The CMBG has consistently demonstrated its commitment to promoting education and empowering young individuals. As a result, we have partnered with Tritech since 2021, and I believe that this partnership has opened new doors and possibilities for our young scientists. We are incredibly honoured to be part of such a dynamic and inspiring environment,” said Dr Mariana Erasmus, Vice Director: CMBG and Tritech EXCO member.

Power of science and technology

According to Dr Erasmus, at the CMBG, they believe in the power of science and technology to transform our world. Their involvement in this event aligns perfectly with the centre’s commitment to fostering innovation, encouraging critical thinking, and nurturing the next generation of scientists and innovators.

“We are excited about the opportunities Tritech presents to the university to engage with cutting-edge projects, to exchange ideas, and build lasting collaborations. The spirit of curiosity and exploration that Tritech embodies is exactly what drives our institution’s mission forward.”

In addition to assisting with the judging of projects during the National Science Competition at the Merensky Agricultural Academy in Tzaneen, the CMBG presents a fun but intellectually stimulating activity, showcasing various STEM-related disciplines that UFS offers to inspire students from across South Africa to celebrate scientific discovery. Each year, the CMBG collaborates with a different department for these activities, and this year, in October 2024, the collaboration was with the UFS Department of Chemistry.

‘Science Olympics’

The theme for Tritech 2024 was “Science Olympics”, and after the formalities of the project presentations were completed, the fair kicked off with a grand procession led by bearers of flaming torches and flags reminiscent of Olympic ceremonies. “Learners marched proudly, symbolising their commitment to science, with representatives from UFS and Tritech EXCO leading the way, an unforgettable visual display honoured the learners’ passion for exploration,” said Dr Erasmus.

The event transitioned into a video presentation explaining the misuse of performance-enhancing drugs in sports, followed by interactive activities focused on analysing possible doping agents. Thereafter, the UFS team guided learners through hands-on experiments, demonstrating the science behind identifying performance-enhancing drugs. Through engaging, real-world applications, learners were not only able to detect these substances but quantify their findings, making the learning experience both fun and educational.

As the night closed, the Chemistry team mesmerised the audience with a ‘magic show’. Explosions of colour, booming sounds, and flashes of light filled the sky, leaving everyone in awe. The show combined entertainment and chemistry, showcasing the wonders of science through spectacular reactions.

On TV

The fair concluded the next day with activities like kart building and livestock showcases, ending with a prize-giving ceremony to reward the learners for their hard work throughout the year. Adding to the excitement, the event is set to be featured in a new television series, with the pilot episode filmed during the weekend of Tritech Nationals 2024.

“The series promises to bring the Tritech experience to life for a wider audience, aiming to capture the incredible spirit, creativity, and innovation that defines Tritech. It will be an incredible opportunity to gain recognition, inspire others, and highlight the importance of science and technology in solving real-world challenges,” Dr Erasmus concluded.

This year’s fair was a celebration of knowledge, creativity, and the endless possibilities of science, leaving a lasting impact on all who attended.

Science and goodwill meet drought-stricken communities
2016-03-02

Description: Disinfecting tankered water  Tags: Disinfecting water

“Everyone should contribute to the delivery of clean water to every individual,” says UFS researcher.

The drought in South Africa has impacted the country in many ways. Apart from its economic and environmental implications, the drought also has social implications, leaving some communities without water.

Since 21 January 2016, the Department of Water and Sanitation (DWS) is working together with the Department of Microbial, Biochemical, and Food Biotechnology at the University of the Free State. Dr Mariana Erasmus, post-doctoral fellow in the department, was appointed to lead a project for disinfecting tankered water supplied by the DWS to communities without water in the Qwaqwa area - which falls under the Maluti-a-Phufung Local Municipality.

She is working on the project with Robbie Erasmus from BioSense Solutions and Martin Bambo from DWS. A total of 53 trucks, 91 tanks, and 420 500 litres of water was disinfected so far, using sodium hypochlorite. “This is standard practice around the world,” Dr Erasmus said.

The work done by the UFS and DWS, who is monitoring the water quality as well as the process of water delivery, is very important. Disinfecting the trucks used to deliver water to drought-stricken communities decreases the formation of biofilm inside the tanks. “The biofilm could contain harmful bacteria such as E-coli. It is important to note that this is mostly the result of secondary pollution, since the water quality from the source where it was taken from, proved to be good. Drinking water with this harmful bacteria that has not been properly managed, can lead to health issues in humans when consumed,” Dr Erasmus said.

The Department of Microbial, Biochemical, and Food Biotechnology, interacting with the DWS on several water-related issues, volunteered to get involved in the project. They strongly believe that everyone should contribute to the delivery of clean water to every individual.
