All 23 grade 10 learners taking part in the University of the Free State’s (UFS) Creative Clubs Programme were awarded medals at the Bloemfontein regional Eskom Expo for Young Scientists (EYS) competition from 3 to 5 August 2023.

The learners, who attend Bloemfontein township schools, had been working on their projects for over a year as part of the Creative Clubs Programme, which is run by the UFS Faculty of Education. Guided by veteran Expo facilitators Dr Angela Stott and Coretha van den Heever, they attended 30 sessions on the UFS South Campus, with a total of 140 hours of face-to-face contact time, coupled with many hours of individual work at home, to prepare for the competition.

Their hard work paid off handsomely, with all 23 learners (who worked on 21 projects) achieving medals: six bronze, seven silver, and eight gold. Additionally, five of the learners won best-in-category awards, three won SA Youth Water prizes, and three were shortlisted for the international EYS competition.

“As an introvert, I found it difficult to explain my project to people, but I’ve developed communication skills and confidence through Expo,” said 15-year-old Nicolas Hugo, from Kagisho Secondary School, whose project won a gold medal. Nicolas studied water pollution levels at two inflow sites in the Bloudam catchment area, as well as the dam itself and its outflow, showing the astounding cleaning effectiveness of water reeds.

In addition to his gold medal he won the prize for the best project in his category, a special award in the category of water projects, and for the Best Development Project.

The UFS has a strong commitment to community engagement, and has been working with township schools throughout the province via school-university partnerships for over a decade. The 2023 Bloemfontein EYS competition celebrated the legacy of these partnerships not only through the 23 learners who were directly involved in the UFS programme over the past year, but also through the participation of 14 learners from two schools (Senakangwedi and Setjhaba Se Maketse) in Botshabelo as a direct result of the UFS’s work in those schools in the past. Before UFS ended its partnership with these schools, learners who had been involved in Expo programmes conducted by Dr Stott established science clubs in their schools. These clubs have continued to operate years after UFS exited the schools and the founding learners matriculated. This year these clubs yielded the winning project, Solar Power Stand, by Simthembile Hlahliso and Kabelo Sekoere from Senakangwedi High School.

Many of the learners said they have learned important skills through this process. “I didn’t know how to use a computer, but now I’m so good,” said Sylvia Hlangabeza, who won a gold award.

“I’m so proud of her, I cried,” said Sylvia’s proud mother.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
