UFS South Campus Creative clubs Initiative
UFS staff members from the Social Responsibilities Projects, Patience Aba, Judith Lefa, Noluthando Zwane, Dr Angela Stott, and Queen Selema, with a group of learners from the Ikaelelo Senior Secondary School looking at the effect of wind on the evaporation rate of water. This is one of the science experiments used as exemplars to stimulate the learners to plan their own science expo projects.

“This class teaches us how things work, and it gives us many ideas.” These are the words of Bokamoso Mahlasi, a Grade 9 learner at Ikaelelo Senior Secondary School, who says he dreams of becoming a radiologist one day. 

He is part of a group of 100 Grade 9 learners from schools around Bloemfontein, who – once a week for two hours – have the opportunity to learn more about mathematics, science, coding and to prepare science expo projects. This is made possible through the Creative Clubs programme, an initiative of the Social Responsibility Projects on the University of the Free State (UFS) South Campus. 

An opportunity to expand horizons

Dr Angela Stott, Researcher and Teacher Educator in the Social Responsibilities Projects, believes that they are providing township learners, who tend not to have much access to extracurricular opportunities, the chance to expand their horizons, obtain problem-solving and reasoning skills, and increase their interest in mathematics, science, and coding through a range of extracurricular extension activities.

Dr Joleen Hamilton, initiator and coordinator of this programme, says, “The learners attending these sessions are achievers in the current school system. Teachers often don’t have time to give extra stimulation to higher-achieving learners. With Creative Clubs, we want to address that gap.”

She continues: “Besides creating an interest in mathematics, science, and coding, we also focus on building self-esteem and confidence. Our thinking is that if learners believe in themselves, they are more willing to take on challenges. Developing skills such as perseverance and reflection form part of our focus as well. With some of the activities we also give learners the opportunity to work as a team, preparing them for real-life situations where one often needs to work in a group setting. By developing the mentioned skills, we aim to empower learners to excel in different areas.”

The importance of mathematics in real life

During the Creative Clubs sessions, a series on the basics of doing a science expo project is presented to stimulate interest in this competition and to guide the learners in planning their own science expo projects. Dr Stott adds that they are also presenting a session on extracurricular mathematics activities. “This includes problem-solving tasks, brain teasers, and games. We emphasise the importance and use of mathematics in real life,” explains Dr Hamilton.

We also focus on building self-esteem and confidence. Our thinking is that if learners believe in themselves, they are more willing to take on challenges. – Dr Joleen Hamilton

Also in the pipeline is a planned outing to the Naval Hill Planetarium, as well as a session introducing coding, where learners will be playing the Boats and Tanks coding game, teaching them the basic coding commands.

UFS researcher engineers metal surfaces
2015-03-03

Shaun Cronjé, a PhD student, in a surface characterisation laboratory at the UFS.

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
