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.

Mineral named after UFS professor
2017-09-29

Description: Mineral tredoux Tags: International Mineralogical Association, tredouxite, Prof Marian Tredoux, Department of Geology, Barberton 

Tredouxite (white) intergrown with bottinoite (light grey),
a complex hydrous alteration product. The large host
minerals are nickel-rich silicate (grey), maybe willemseite,
and the spinel trevorite (dark grey).


More than five thousand minerals have been certified by the International Mineralogical Association (IMA). One of these minerals, tredouxite, was recently named after an academic at the University of the Free State (UFS). 

Tredouxite was named after Prof Marian Tredoux, an associate professor in the Department of Geology, to acknowledge her close to 30 years’ commitment to figuring out the geological history of the rock in which this mineral occurs. The name was chosen by the team which identified the new mineral, consisting of Dr Federica Zaccarini and Prof. Giorgio Garuti from the University of Leoben, Austria, Prof. Luca Bindi from the University of Florence, Italy, and Prof. Duncan Miller from the UFS. 

They found the mineral in the abovementioned rock from the Barberton region in Mpumalanga, in May 2017.

In the past, a mineral was also named after Marie Curie
With the exception of a few historical (pre-1800) names, a mineral is typically named either after the area where it was first found, or after its chemical composition or physical properties, or after a person. If named after a person, it has to be someone who had nothing to do with finding the mineral.

Prof Tredoux said: “As of 19 September 2017, 5292 minerals had been certified by IMA. Of these, 81 were named after women, either singly or with a near relation. Marie Curie is named twice: sklodowskite (herself) and curite (plus husband). Most of the named women are Russian geoscientists.”

Another way to assess the rarity of such a naming is to consider that fewer than 700 minerals have been named after people. Given that there are by now seven billion people on the planet, it means that a person who is granted a mineral name becomes one in 10 million of the people alive today to be honoured in such a way. To date, over a dozen minerals had been named after South Africans, three of them after women (including tredouxite).

It contains nickel, antimony and oxygen
The chemical composition of tredouxite is NiSb2O6 (nickel antimony oxide). This makes it the nickel equivalent of the magnesium mineral bystromite (MgSb2O6), described in the 1950s from the La Fortuna antimony mine in Mexico.  

“This announcement is of great academic importance: the discovery by the Italian team of a phase with that specific chemical composition will undoubtedly help me and my co-workers to better understand the origin of the rock itself,” she said. She also expressed the hope that it may raise interest in the Department of Geology and the UFS as a whole, by highlighting that world-class research is being done at the department. 

The announcement of this new mineral was published on the International Mineralogical Association Commission on New Minerals, Nomenclature and Classification website, the Mineralogical Magazine and the European Journal of Mineralogy.
