Seven students at East Norfolk Sixth Form College have taken part in the annual Chemistry Olympiad.

The contest encourages students to pit their wits against some tough questions, set by a committee of teachers from schools and universities.

They devise a whole range of interesting and challenging questions on real and relevant chemistry, raising awareness of what the subject is all about.

Three students were awarded silver certificates – Rose McNelly, Matthew Timms and Annabel Canham. Ellie Wilson, Zeki Shaw and Gigi Nicolson were awarded bronze certificates.

Chemistry teacher, Karen Dawson, said: 'There is no doubt that these questions are demanding: they do not rely on the relatively easy recall of information which students will have met before, but instead on thinking and trying to work out answers to unfamiliar questions.

'This is much more difficult.'
