Cambridge Chemistry Challenge Lower Sixth
This is essentially a lower sixth Chemistry Olympiad, organised by Cambridge University, in the form of a 90 minute written paper, designed to challenge students more than standard AS questions.
This year, one question was about titanium dioxide, TiO2 which is commonly used as a brilliant white pigment for instance in toothpaste, paints, sunscreens and even as a food additive (E171).
Another question was about Pyrethroid insecticides and their use on treated mosquito nets to reduce infection with mosquito-borne diseases.
Nationally there were 7200 entries for the challenge and only those scoring more than the ‘average’ received awards.
Copper awards went to:
Zion Chan Matthew Cullen Joshua Finn
Aangelo Gurusinghe Navin Ma Akshay Mistry
Gareth Owen Alexander Patecki Ben Urwin
(these boys have already been given their certificates).
Silver awards to:
Vinaen Charadva Sai Kotecha Ravi Nathwani
Julian Wat Justin Wong
Gold awards to:
Sean McGuire Derek Yu
Well done to all those who took part!
