If you’re in the UK, have a go at this science writing prize from the Wellcome Trust and the Guardian. The winners will have their work printed in the ‘Guardian’ or the ‘Observer’, receive a £1000 cash prize and benefit from a science writing workshop at the ‘Guardian’.
One category is for non-professionals and undergraduate students – that includes you, super-smart IB Biologists. The closing date is 20th May, so it’s perhaps not the best idea for students in their exams!
