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.”

Researchers international leaders in satellite tracking in the wildlife environment
2015-05-29

 

Ground-breaking research has attracted international media attention to Francois Deacon, lecturer and researcher in the Department Animal, Wildlife and Grassland Sciences at the UFS, and Prof Nico Smit, from the same department. They are the first researchers in the world to equip giraffes with GPS collars, and to conduct research on this initiative. Recently, they have been joined by Hennie Butler from the Department of Zoology as well as Free State Nature Conservation to further this research.

“Satellite tracking is proving to be extremely valuable in the wildlife environment. The unit is based on a mobile global two-way communication platform, utilising two-way data satellite communication, complete with GPS systems.

“It allows us to track animals day and night, while we monitor their movements remotely from the computer. These systems make possible the efficient control and monitoring of wildlife in all weather conditions and in near-to-real time. We can even communicate with the animals, calling up their positions or changing the tracking schedules.

“The satellite collar allows us to use the extremely accurate data to conduct research with the best technology available. The volume of data received allows us to publish the data in scientific journals and research-related articles.  

“Scientific institutions and the public sector have both shown great interest in satellite tracking, which opens up new ground for scientific research for this university. Data management can be done, using Africa Wildlife Tracking (AWT) equipment where we can access our data personally, store it, and make visual presentations. The AWT system and software architecture provide the researcher with asset tracking, GPS location reports, geo-fencing, highly-detailed custom mapping, history reports and playback, polling on demand, history plotting on maps, and a range of reporting types and functions,” Francois said.

Data can be analysed to determine home range, dispersal, or habitat preference for any specific species.

Francois has been involved in multiple research projects over the last 12 years on wildlife species and domesticated animals, including the collaring of species such as Black-backed Jackal, Caracal, African Wild Dog, Hyena, Lion, Cheetah, Cattle, Kudu, Giraffe, and Black Rhino: “Giraffe definitely being the most challenging of all,” he said.

In 2010, he started working on his PhD, entitled The spatial ecology, habitat preferences and diet selection of giraffe (Giraffa camelopardalis giraffa) in the Kalahari region of South Africa.

 

Since then, his work has resulted not only in more research work (supervising four Masters students) but also in a number of national and international projects. These include work in the:

  • Kalahari region (e.g. Khamab Nature Reserve and Kgalagadi Transfrontier Park)
  • Kuruman region (Collared 18 cattle to identify spatial patterns in relation to the qualities of vegetation and soil-types available. This project took place in collaboration with Born University in Germany)
  • Woodland Hills Wildlife Estate and Kolomella Iron Ore – ecological monitoring
  • A number of Free State nature reserves (e.g. Distribution of herbivores (kudu and giraffe) and predators (camera traps)

Francois is also involved with species breeding programmes and management (giraffe, buffalo, sable, roan, and rhino) in Korrannaberg, Rustenburg, Hertzogville, Douglas, and Bethlehem as well as animal and ecological monitoring in Kolomella and Beesthoek iron ore.

Besides the collaring of giraffes, Francois and his colleagues are involved in national projects, where they collect milk from lactating giraffes and DNA material, blood samples, and ecto/endo parasites from giraffes in Southern Africa.

With international projects, Francois is working to collect DNA material for the classification of the nine sub-species of giraffe in Africa. He is also involved in projects focusing on the spatial ecology and adaptation of giraffe in Uganda (Murchison Falls), and to save the last 30 giraffe in the DRC- Garamba National Park.

This project has attracted a good deal of international interest. In June 2014, a US film crew (freelancing for Discovery Channel) filmed a documentary on Francois’ research (trailer of documentary). Early in 2015, a second crew, filming for National Geographic, also visited Francois to document his work.
