This year’s RCSU Science Challenge is under way.
From their website:
The RCSU Science Challenge is an annual competition run by the Royal College of Science Faculty Union, and generously funded by the Faculty of Natural Sciences here at Imperial College London. The challenge is an essay competition that aims to encourage scientific debate, reasoning and the communication of science in a public-friendly context. Entries in this two-category competition are open to all students of Imperial College (not Faculty specific) and (in a separately judged category) students at school or college in the United Kingdom.
There are four essay questions to choose from, and you’ll need to write 800 words. The questions and full submission criteria can be found on the RSCU Science Challenge website.
