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.

Well-established root system important for sustainable production in semi-arid grasslands

The importance of a well-established root system for sustainable production in the semi-arid grasslands cannot be over-emphasised.

A study of Prof Hennie Snyman from the Department of Animal and Wildlife and Grassland Sciences at the University of the Free State is of the few studies in which soil-water instead of rainfall has been used to estimate above- and below-ground production of semi-arid grasslands. “In the past, plant ecological studies have concentrated largely on above-ground parts of the grassland ecosystem with less emphasis on root growth. This study is, therefore, one of the few done on root dynamics in drier areas,” said Prof Snyman.

The longevity of grass seeds in the soil seed bank is another aspect that is being investigated at present. This information could provide guidelines in grassland restoration.

“Understanding changes in the hydrological characteristics of grassland ecosystems with degradation is essential when making grassland management decisions in arid and semi-arid areas to ensure sustainable animal production. The impact of grassland degradation on productivity, root production, root/shoot ratios, and water-use efficiency has been quantified for the semi-arid grasslands over the last 35 years. Because of the great impact of sustainable management guidelines on land users, this study will be continuing for many years,” said Prof Snyman.

Water-use efficiency (WUE) is defined as the quantity of above- and/or below-ground plant produced over a given period of time per unit of water evapotranspired. Sampling is done from grassland artificially maintained in three different grassland conditions: good, moderate, and poor.

As much as 86, 89 and 94% of the roots for grasslands in good, moderate and poor conditions respectively occur at a depth of less than 300 mm. Root mass is strongly seasonal with the most active growth taking place during March and April. Root mass appears to be greater than above-ground production for these semi-arid areas, with an increase in roots in relation to above-ground production with grassland degradation. The mean monthly root/shoot ratios for grasslands in good, moderate, and poor conditions are 1.16, 1.11, and 1.37 respectively. Grassland degradation lowered above- and below-ground plant production significantly as well as water-use efficiency. The mean WUE (root production included) was 4.79, 3.54 and 2.47 kg ha -1 mm -1 for grasslands in good, moderate, and poor conditions respectively.

These water-use efficiency observations are among the few that also include root production in their calculations.
