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.

Inaugural lecture: Prof André Pelser

2004-06-04

Tendencies and changes in the South African population structure in future decades.

Within the next five years South Africa will for the first time in the past century enter a period where the death rate will exceed the birth rate, largely due to the impact of HIV / AIDS.

According to sociologist Prof André Pelser, sociologist at the of the University of the Free State’s (UFS) Department of Sociology, the death rate exceeding the birthrate is only one of three demographic trends which will fundamentally change South Africa’s population structure in the following decades.

He was speaking at the UFS in Bloemfontein during his inaugural lecture as professor this week.

Prof Pelser said that according to some models the South African population will decrease within the next five decades by between 10 and 26 percent.

A second important trend which will impact on the population structure is the progressive ageing of the population.

He said the group above 65 years is the only age category in the South African population which will witness sharp increases in the next few decades.

In the next 50 years, the group younger than 15 years will reflect a decrease of 39% and those older than 65 years in South Africa will increase by approximately 110% in the next two decades.

“The systematic “greying” of the South African population will create the same economic and welfare issues as those with which governments in some more developed countries are already grappling,” said Prof Pelser.

A third trend affecting the South African population structure is the constant decrease in life expectancy.

Life expectancy at birth for the total population is projected to decrease from approximately 62 years at the beginning of the 1990’s to 43 years in 2015-2020, with sharp differences between the various population groups.

These tendencies and changes to the South African population structure have serious implications, he said.

For example, he said, the reduction in life expectancy could compromise national development objectives.

“It is estimated that more than a quarter of the economically active population will be infected with HIV by 2006,” said Prof Pelser.

The increase in the population, in age category 65, will place a financial burden on government and the economically active sector.

“Especially worrying is the fact that ever-increasing proportions of the state budget will be allocated to health and welfare services and this at the expense of other priorities like education, infrastructure, criminal justice system and trade and industry, to name but a few,” he said

“A comprehensive and integrated strategy is thus vitally important in addressing the overarching issues caused by changes in the population structure,” said Prof Pelser.
