At the opening of the Science Education Centre on the Bloemfontein Campus, were, from the left: Prof Loyisa Jita, Prof Francis Petersen, Dr Cobus van Breda, and the Honourable Dr Tate Makgoe.

“Music is liquid architecture; architecture is frozen music.” – Johann Wolfgang von Goethe.

These were the words used by Marius Coetzee of the Odeion School of Music when he introduced a colleague from the same department, Prof Anmari van der Westhuizen, before she performed a cello solo (GYÖRGY LIGETI mov1) during the opening of the Science Education Centre (Sci-Ed) on the Bloemfontein Campus of the University of the Free State (UFS).

“A worthy piece of music to celebrate a signature building,” Coetzee stated. 

The building accommodates the only science education centre in central South Africa, with its mission the advancement of innovative and effective mathematics and science teaching and learning, which is beneficial to student teachers, in-service teachers, learners, parents, and the public at large. 

During the opening of the event, the Rector and Vice-Chancellor of the UFS, Prof Francis Petersen, said universities are about interactive spaces such as the Science Education Centre. He believes it is in spaces such as these where innovations and initiatives are created to tackle science (and the world) of the future.

“We must seek more of these spaces at the UFS. We must ensure that graduates from our university have a solid discipline – that they have their basis right – to prepare them to interact and engage in a multidisciplinary fashion, because that is what the world outside requires." 

Speaking about the role of universities in society, Prof Petersen said the purpose of a university is to engage with society. “If we can’t show the public the value of what we have here, the public will ask what the value of universities is. Why do universities exist in the first place? Our role is always to look at things that we do best: our intellectual ability to understand how things work; us challenging specific things and infusing that into society. It is for this reason that we have public lectures, science centres, and other platforms, allowing society to engage with us.”

“Universities are places that evolve continuously, and this centre is an excellent example.”

Referring to the UFS’ twelve-year strategic plan, Vision 130, he said besides visibility, the university will also focus on impact. “We can only show our impact through our graduates, the knowledge that we generate, the research that we conduct, and engaging with society. This centre is all about that.”

The Honourable Dr Tate Makgoe, the MEC for Basic Education in the Free State, shared the sentiment that the impact of universities must be felt by the community. “I am inspired to know that this facility is open to the public. Government will be the main beneficiary of this science centre and we will use it profitably. Among others, I will send our Foundation Phase teachers here,” he stated.

An aesthetic and educational added value

Dr Cobus van Breda, Manager of Sci-Ed and Programme Director of the Science-for-the-Future, an initiative hosted by the UFS Faculty of Education to address the challenge of mathematics and science teaching and learning in South Africa, said that the project had 289 884 participants between 2009 and 2022. 

He explained that this project implements mathematics and science teachers’ professional development and outreach programmes across the country.

“In order to extend its impact, it was decided to establish a Science Education Centre to not only enhance its teaching and learning programmes to student educators and in-service teachers, but also to provide a platform to include science communication and engagement with the public. Sci-Ed will be open to the public, and through outreach programmes as well as formal and non-formal visits to the centre, the community can make use of the benefits of the centre,” says Dr Van Breda.

He sees the promotion of parental and family involvement in children’s learning as a priority for Sci-Ed. “Programmes and events aimed at empowering parents and guardians to support their children will also be presented,” said Dr Van Breda.

The Science Education Centre’s main objective, he says, is to create a STEAM+ (Science, Technology, Engineering, Art, Mathematics, and related areas) environment in the South African context, where innovative and 21st century science education (Grade R to Grade 12) can thrive. “The intent of Sci-Ed is to expose, inspire, and empower users while engaging in STEAM experiences and interactive exhibits,” he added. 

Merging the old with the new

Dr Van Breda – the passion, drive, and dedication behind Sci-Ed – believes that teaching philosophy and facilities must complement each other. This resulted in the construction of the science centre, a realisation of a dream that started in 2005. 

The centre was built in three stages. Phase one of the development involved the construction of the building. An outdoor park area was created during phase two, and interactive exhibits, programmes, and events were planned, developed, and enhanced during phase three to serve the purpose of the facility. “The last part will continue for about six more months, as we want to develop authentic exhibitions that support the university’s teaching and learning philosophy,” said Dr Van Breda.

The Sci-Ed Building, designed to accommodate all the crucial elements of a modern science education centre, is an extension of the existing Winkie Direko Building. Dr Van Breda explained that the architect designed the new building to seamlessly merge with the Winkie Direko Building, which dates from an earlier era. “A conscious decision was made to use some cladding from the old building where it merges into the new facility. This architectural feature can also be seen as a metaphor for building a bright new future on sound foundations,” he said. 

With its interactive exhibits, Sci-Ed will make it possible for the numbers of students, student educators, in-service educators, learners, parents, other interest groups and the public who will enter its doors, to engage in a hands-on manner with activities, and as such experience a science principle. “Using interactive exhibits, we also hope to evoke questions that will stimulate discussion and enhance learning, especially coincidental learning,” said Dr Van Breda.

He added that Sci-Ed will also serve as a social space on campus, where all students can interact within a fun and exciting popular science environment.

Prof Loyiso Jita, Dean of the Faculty of Education, described the building as a dream come true. It is not just about the building, it is also about creating an intellectual space, both indoors and outdoors, to encourage students, staff, and the community to interact with science.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
