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.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
