The Centre for Mineral Biogeochemistry (CMBG) at the University of the Free State (UFS) was part of another successful Tritech National Science and Technology Fair 2023 – an exciting STEM (Science, Technology, Engineering, and Mathematics) research competition.

The UFS has partnered with Tritech and other sponsors since 2021 to bridge the gap between high school and tertiary education. Tritech, which started in 2008 and is open to all Grade 7-12 learners, aims to equip them for tertiary education by introducing them to scientific research and incorporating modern technology in research. This is an annual competition that starts at the regional level and goes all the way to the national level, with the national competition held at the Merensky High School, in Tzaneen, Limpopo from 20-21 October 2023.

Schools from across the country take part in the fair, but learners compete in groups rather than schools. 

Every year the Tritech Nationals are divided into four main activities over the weekend: 
  1. On the Friday afternoon the learners present their STEM projects in which they have identified a problem in a community, do research to find a solution, do experiments to test if the solution will solve the problem, then test the solution in the community, and lastly, present their findings to a group of judges and learners in similar fields. Fields include Life Sciences, Engineering and Design, Maths, Science and Technology, Environmental and Social Sciences, Health Sciences and Agricultural Sciences.
  2. Friday evening is usually a fun activity for the learners.
  3. On Saturday morning the learners are exposed to work-related activities that give them insight into professions they could pursue in the science field. This activity is sponsored and presented by the UFS. 
  4. The last activity of the weekend is the prize-giving on Saturday afternoon where the learners get rewarded for the quality of their projects and honour, celebrate, and encourage excellence. 

“Every year the CMBG includes different departments from the UFS in alignment with the theme for the event, to ignite a lasting passion for innovation toward promising careers in the STEM fields. In 2022 the theme for Tritech was “Crime Scene Investigators” and the CMBG team created a very realistic crime scene and laboratory setup to teach the learners about Forensic Science. The learners scored our CSI activity as the best for the weekend and we knew that for the 2023 Nationals, we had our work cut out to do even better,” says Dr Erasmus. 

Learning about food health and safety

This year, Prof Maryna de Wit and her students from the Department of Sustainable Food Systems and Development (SFSD) joined the CMBG team, to introduce learners to food health and safety, food preservation, food systems and development, as well as sensory analyses. 

Island, shipwrecks, and wilderness survival

Dr Mariana Erasmus, Deputy Director of the Centre for Mineral Biogeochemistry (CMBG), spearheads the Tritech team from the UFS. CMBG, as part of its community outreach programme, is not only a sponsor of the event but is also the organiser of the main activity together with another UFS department. 

Dr Erasmus says the theme for Tritech 2023 was “Survival MasterChef”, where for the two activity events, the Tritech learners were “stranded” on an island. This exercise was a great way to promote leadership qualities, encourage creativity and confidence, promote teamwork and active communication, and increase critical thinking in learners, while they got to know more about food health and safety practices.

“It was all island, shipwrecks, and wilderness survival at this year’s event where learners had to survive after being ‘stranded’ on an island. To escape, the learners had to build a boat and while they waited to be rescued, they needed to adapt to island life to survive by preparing healthy meals, as well as preparing meals and drinks to treat dehydration and scurvy,” says Dr Erasmus. 

“During the prize-giving, some of the learners received shadowing opportunities at the UFS and other sponsors to advance their education. Bronze, silver, and gold medals, together with participation certificates, were awarded to other deserving learners.”

SA cannot sustain momentum - Boesak

South Africa finds it increasingly difficult to live up to the challenges facing it as a nation because of its failure to meet its democratic ideals and possibilities, peace and lack of self-belief.

This was according to renowned cleric and former political activist, Dr Allan Boesak, who recently delivered the CR Swart Memorial Lecture, the oldest memorial lecture at the University of the Free State (UFS). His lecture was on the topic Creating moments, sustaining momentum.

He said South Africa had plenty of opportunities to show the whole world what was possible if all the people of this country joined hands and worked together to build a truly united society. However, he said, the country somehow invariably contrived to find its way out of these wonderful possibilities.

He cited events of historical significance like Codesa, the inauguration of Nelson Mandela as the first democratic president of South Africa, the assassination of South African Communist Party leader, Chris Hani; and the rugby and soccer world cups.
To drive his point home about this dismal failure of the country to “sustain momentum”, he alluded to the current public servants’ strike that is gradually crippling public service.

“The public servants’ strike was neither unexpected nor is it completely unjustifiable. Most of us have understanding for the frustration of teachers and health workers. Their demands resonate with most of us, and I think that it is scandalous of SACP fat cats to tell workers to “stop crying like babies,” he said.

He also added to the criticism of the much-maligned decision of the government to spend billions of taxpayers’ money to purchase weapons when there was “no discernible military threat” to the country. He said the greatest threat to the security of the country was poverty, inequality and social cohesion.

“As for the argument that arms sales bring in foreign exchange – how can we be instrumental in killing the poor elsewhere with the intention of feeding our poor, and then our ill-gained profits feed only the already well-fed?” he asked.
“Can we see the hopeless contradiction, the total impossibility of being both the apostle of peace and a merchant of death?”

He also lambasted the Black Economic Empowerment (BEE) policy of the government which he said benefited only those connected to the political aristocracy.

“It couples with the unashamed, in-your-face display of wealth by the privileged elite in this country, the crass materialism of the so-called “bling generation”, and the casual carelessness with which promises to the poor are given and treated. It is only the public symptom of the deep-seated scorn our political elites feel for the poor,” he said.

He said the government’s disdain to the poor was “setting fire to our future”.

“The anger of people on the ground can no longer be denied or ignored, and little by little, the leadership articulating and directing this anger is being estranged from politically elected leadership, and even more disturbing, from our democratic processes,” he said.

He concluded that the country’s difficulty in dealing with race and racism was putting the reconciliation process kick-started by Mandela just over a decade ago, under a threat.
