Molo Mhlaba Primary School in the far-flung part of Khayelitsha is so new that even local residents and other schools in the area weren’t able to guide the UCT Physics contingent through the last 500 m of their journey on Wednesday 13 June – but after driving around for some time, asking directions in rusty Xhosa, the team was eventually spotted by one of the organisers and ushered into the school.

Dr Trisha Salagaram, Gregor Leigh and MSc student Lizelle Niit (and, most importantly, a car load of demonstration equipment!) had been invited by The Project for the Study of Alternative Education in South Africa (PRAESA) to lay on a mini science show as part of the launch of the children’s book written by Lucy Hawking and her famous father, George’s Secret Key to the Universe, which has been translated into several South African languages.

The event was attended by several hundred pupils from surrounding schools, each one of whom left with a copy of the book after having had passages from it read to them by the very woman who translated it into isiXhosa, UCT School of Education’s Xolisa Guzula. According to the organisers, however, the highlight of the afternoon was the series of interactive science shows. Students ranging from 4 to 14 years old were treated to a variety of demonstrations and hands-on experiences – a ball “floating” in an air stream, cans being crushed by nothing more than the atmosphere, home-made divers in water bottles which sank or rose apparently in response to commands in isiXhosa, and liquid nitrogen and water propelled rockets which went WHOOOSH!! and disappeared high over the roof tops, never to be seen again.

Molo Mhlaba in Khayelitsha is one of a “network of Pan-African low-fee independent private schools for girls, providing quality STEAM education through innovative teaching and learning strategies” (https://www.facebook.com/molomhlaba/). Given the school’s strong emphasis on science and mathematics, Director Rethabile Sonibare was very happy to have established a link with UCT Physics and is keen to maintain the contact.
