They are colourful, provocative and educative - and a great asset to local science teachers. The four posters, produced by UCT's Faculty of Science as part of the National Science Week, highlight the importance of science in people's daily lives; and more importantly, attract the country's youth to pursue (and remain in) science-related studies and careers.

The posters augment the faculty's strong outreach programme, workshops and Science Day. Over the past six years, they've contributed 22 posters. This year's topics are Drought-Tolerant Crops by Professor Jill Farrant and Keren Cooper; Energy: Renewable and Non-renewable Energy by Kirsten Scott and Dr Rachel Wynberg; and Chimango Hara: Fishing Responsibly by Dr Lynne Shannon and Associate Professor Astrid Jarre; and Hydrogen: Fuel of the Future by Dr Clive Oliver.
