Science for the Future (S4F) summit

Teachers from across the country and representatives of six other universities recently gathered at the University of the Free State (UFS) to celebrate the achievements of the Science-for-the-Future (S4F) Teacher Professional Development programmes as well as the successful collaboration between the UFS and other universities.  

The Science-for-the-Future unit in the Faculty of Education hosted a summit in the Centenary Complex on the Bloemfontein Campus on 30 September 2022. The Rector and Vice-Chancellor of the UFS, Prof Francis Petersen, delivered the keynote address at the summit. Representatives from the South African National Roads Agency (SANRAL) – the official sponsors of the Science for the Future initiative – were also present, along with 300 teachers and representatives from the Department of Basic Education. 

In his welcoming address, Prof Patrick Mafora, Vice-Dean of the Faculty of Education, said the initiative exemplifies the UFS’ institutional goals, such as increasing our contribution to local, regional, and global knowledge.  It also supports development and social justice through engaged scholarship.

Improving the quality of teaching and learning for Math and Science 

Dr Cobus van Breda, Programme Director of S4F and Project Manager of the Universities Collaboration initiative, provided background regarding the programmes and stated that “… we know from research that there are many factors that prevent learners in rural areas from excelling in Mathematics and Science. These include subject content knowledge, lack of teaching resources at school and at home, along with a lack of parental involvement, among others.” He said the project aims to address the challenges related to Mathematics and Science teaching and learning in the country. One of the ways in which this goal can be accomplished, is by empowering teachers and learners with the necessary tools, including resources and knowledge, to create a successful learning space for Mathematics and Science. “Our mission is the advancement of innovative and effective Mathematics and Science teaching and learning,” he indicated.

Representatives from the DBE and other institutions were also given the opportunity to highlight the impact of the initiative in their respective institutions. “Our public schooling system, especially in poor and rural areas, is in crisis – more especially in the Eastern Cape. This is due to a lack of learning support and a lack of sufficient skills. This created a need for innovative, sustainable, and tactical solutions to improve the quality of teaching and learning for Math and Science. The Science for the Future initiative is exactly that,” explained Prof Jogy Alex from the Walter Sisulu University.

Making a difference and changing people’s lives 

During his keynote address, Prof Petersen indicated that he preferred the word ‘co-creation’ instead of ‘collaboration’, and he urged the “sponsors not only to contribute funding, but really contribute towards the intellectual project of this programme”. Surely, they have learnings and some ideas that can strengthen and expand the project, he said. Prof Petersen also alluded to the fact that SANRAL contributes towards a Research Chair in Science and Mathematics Education in the Faculty of Education, as well as the fact that, at the university, “we don’t exist to create knowledge for the sake of knowledge; we exist to create knowledge so that the knowledge can make an impact”. He referred to the project as an example of how knowledge is converted to practical application.  


Mr Adolph Tomes, Acting Business Operations Executive at SANRAL, also commended the initiative and its impact. “Although we as SANRAL are the funders and we get praise for being funders, this is a phenomenal project, and it is making a difference and changing people’s lives.”

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
