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.”

Migration is a developmental issue - experts

“Migration offers more opportunities for economic growth than constraints. It is an integral part of the processes of globalisation and regional integration.”

This was a view shared by one of the speakers, Dr Monica Juma from the Africa Institute of South Africa, during a panel discussion hosted by the Centre for Africa Studies (CAS) at the University of the Free State (UFS) last week as part of the celebrations of Africa Day on 25 May 2010.

The discussion was premised on the theme, Migration and Africa: From Analysis to Action.

Dr Juma said migrants could be assets for host countries or cities because of their resourcefulness. She said they brought along essential skills that could contribute immensely to the economic development of their host countries or cities.

“Governments are beginning to see migration as a tool for development and working together in developing immigration policies,” concurred another speaker, Mr Vincent Williams from the Institute for Democracy in South Africa (IDASA).

He said, if managed properly, migration could yield positive results. He said effective management of migration should start at local and provincial levels.
And for this to happen, he said, the current immigration laws should be amended as he felt they were no longer relevant, because they were based on what countries wanted to achieve in the past.

“Reform national immigration legislation to encourage permanent settlement and improve service delivery mechanisms and bureaucracy to match population movements,” Dr Aurelia Kazadi Wa Kabwe-Segatti, from the Forced Migration Studies Programme at the University of the Witwatersrand recommended.

However, Mr Williams pointed out that policy convergence was a difficult thing to achieve as migration was a politically sensitive issue. He said decisions that countries made on migration could have a negative or a positive bearing on their relations with one another.

Dr Juma also raised the issue of unskilled migrants which, she said, could be a burden to governments. This was reflected in the current South African situation where foreigners offered cheap labour and thus rendered South Africans who demanded higher salaries unemployable. This was a contributory factor to the xenophobic attacks of 2008. What was essentially a labour problem then manifested itself as a migration problem.

Prof. Simon Bekker from the University of Stellenbosch said South Africa was still losing a significant number of skilled professionals to Europe and North America due to an assumption that spatial mobility led to social or economic mobility.

He also suggested that the government should not restrict internal migration but should address the problem of migration across the borders into South Africa.

Senior Professor at the CAS, Prof. Kwandiwe Kondlo, said while the discussion covered a broad scope, there were some gaps that still needed to be filled in order for an all-inclusive view to prevail. One such gap, he said, was to also accord indigenous traditional institutions of governance space in such deliberations and not base discussions on this issue only on the Western way of thinking.

Africa Day is the day on which Africa observes the creation of the Organisation of African Unity (OAU) on 25 May 1963, to promote the unity and solidarity of African states and act as a collective voice for the African continent; to secure Africa’s long-term economic and political future; and to rid the continent of all remaining forms of colonialism. The OAU was formally replaced by the African Union in July 2002.
