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.”

The OSM Camerata received first place in the 2017 Ictus International Music Competition for bands and orchestras. Marius Coetzee from the Odeion School of Music at the University of the Free State said: “The award was announced in time for the celebration of the orchestra’s fifth birthday.”

OSM a catalyst for excellence
The OSMC was strategically founded in 2012 by Coetzee as the OSM’s flagship chamber ensemble, with the main objective of creating a catalyst for excellence.

Over the past five years, the OSMC has premiered 15 new works by South African composers specially commissioned for them. Highlights remain its participation in the 13th International Conservatory Festival in St Petersburg Russia, where the ensemble received a standing ovation during a gala concert in the Glazunov Concert Hall, as well as the world première of the Cello Concerto for an African Cellist by South African composer, Hans Huyssen, with South African cellist, Heleen du Plessis as soloist. The CD was released in 2014 on the New Zealand Classical Music label, Ode Records in Auckland, New Zealand and was one of five CDs nominated for the Listeners' Choice Award New York in March 2014.

Competition draws participation from Washington to Bloemfontein

The inaugural year of this annual competition drew applicants from Washington State in the US all the way to Bloemfontein in the Free State. Video submissions were judged and narrowed down to a final round from which prize winners were selected.

The OSM Camerata with conductors, Xavier Cloete and Gerhard De Jager, received first place in the University/Conservatory Orchestra category. 

The competition was founded to highlight the work that music educators, conductors, students, performers and community members make in ensembles at the university, community, youth, high school and middle school levels. 

Competition director, Alex Serio says that “many people do not realise the amount of work that it takes to make these ensembles run. What is more is that most of the public does not realise the level of artistic excellence that can be achieved in these ensembles. Ictus International Music Competition was founded to highlight this level
