South African learners impressed in the virtual 2020 Africa Science Buskers Festival, bagging gold, silver and bronze medals along with various cash prizes.
The Africa Science Buskers Festival is an annual science fair, which traditionally brings together more than 500 students and teachers from the African continent. Due to the COVID-19 global pandemic and lockdown, the fair was held virtually this year from 28 to 30 August 2020, and welcomed 175 entries from around the world, including Brazil, Indonesia, Nepal, Turkey, Zambia, Zimbabwe, Malawi, Tunisia and the USA.
Tshepo Lenkoe from Senakangwedi Secondary School in the Free State and Tlotlano Mokgatlhe from Ramatu High School in the North West both won gold medals for their scientific investigations in the festival, with a prize of US$100 each.
Lenkoeās research project, āFive Steps into the Futureā, entailed a model of an umbrella that will be able to convert both sun and wind energy into electrical energy, in order to conserve the electrical energy. Lenkoe previously won a gold medal at the Eskom Expo regional fair in Bloemfontein and a bronze medal at the Eskom Expo International Science Fair for the project in 2019.
Mokgatlheās research project, āAnti-bacterial effect of onion on some of the multi drug-resistant bacterial strainsā, investigated the possible antibacterial effect of onion on some of the multi drug-resistant bacteria, and compared the antibacterial activity of onion with some antibiotics. Mokgatlhe also won second place for the Broadcom Foundation Award in the festival, with a prize of US$250 in the virtual fair.
Eskom Expo alumnus Farida Cajee from HoĆ«rskool Schweizer Reneke in the North West scooped gold in the coveted Peopleās Choice Award in a public vote where she gained more than 5 000 votes for the video of her innovation, āProject Limbsā, which aims to be a more affordable prosthetic alternative. The project entails an electroencephalograph (EEG) headset that measures brainwaves paired with a prosthetic hand from recycled material which is able to move based on thoughts.
A silver medal was awarded to Marcel Sebastian Beukman from Grantleigh College in KwaZulu-Natal for the research project āEffects of greywater in plantsā. Beukman aimed to determine the maximum concentration of grey water that can be used to irrigate garden plants, and to determine whether this will be an effective alternative resource that can be used in the irrigation of plants.
Other local silver medallists included Iziphozonke Mlambo and Nkosenhle Shongwe; while Camryn Griebenow, Joseph Tlhwaela and Aphiwe Sikweza won bronze medals in the virtual fair.
Eskom Expo for Young Scientists Executive Director, Parthy Chetty said: āEskom Expo is very excited that our South African learners continue to win in every competition we entered since February of this year, and during the lockdown period. The hard work of the Eskom Expo team in preparing these young scientists for local and international competitions has really paid off, as these young scientists prepare for a brighter future.ā
Eskom General Manager for Risk and Sustainability and Eskom Executive Committee (EXCO) sponsor of Eskom Expo, Andrew Etzinger congratulated the learners on their impressive representation of South Africa in the virtual fa
āEskom remains committed to the development of young minds through the Eskom Expo platform, which nurtures young scientists in a science exposition landscape that has been drastically changed by the global pandemic, where we are still seeing our local talent winning awards and inspiring other promising young scientists. Congratulations to these bright young scientists, they have displayed resilience and determination during a tumultuous period in our lifetime,ā said Etzinger.
Eskom Expoās online assessments are currently taking place, with entries due on 4 December 2020. Learners are encouraged to visit www.exposcience.co.za to register and upload project documents.
