Number completing different levels
Welcome to the Cambridge Chemistry Challenge, an innovative web-based competition for chemists. The new monthly online challenge, open to anyone, any age, from anywhere in the world will run from November to June. In June there is also a written exam for students in Year 12 attending schools in the UK.
New: June 11, 2013. Papers for the 2013 written paper have been sent to teachers. Please contact us if you have not received them. Email: feedback@C3L6.com
This monthly challenge has five levels - the latest entry level question is shown on the right. You can use whatever means you like to solve the problems, just type your answer in the box and click Submit. If your answer is correct, you will progress to the next level. If you correctly solve all five levels, you will appear on the C3L6 Honours Board. New challenges will be released at 00:00:01 (UK time) on the first day of each month for November to June. Will you be the first person from your school, your town, your country, or even the first person in the WORLD to complete it? You have one month to try and make it on the honours board.
All the previous challenges are now available in the Online Challenge Archive, together with their honours boards. For those of you who got stuck, the HINT and ANSWER functions now work, just type these into the entry box; typing HINT will give you some help to answer the question; typing ANSWER will give you the answer, leading you to the page with the fully explained solution. These functions will NOT be available on the current challenge!
NEW for 2013: We have modified the Cumulative Leader Board scoring system. For the 2012-2013 competition there will be new monthly competitions from November 2012 to June 2013. Points will be awarded depending on position in each month's Honours Board but only an individual's top five months' scores will count towards the final placings. PRIZES will be awarded to the winners from across the world.
Registration for the 2013 UK Year 12 competition is now closed.
This competition aims to stretch and challenge students interested in chemistry, and will provide an excellent experience for anyone considering taking their studies further. Set by an experienced team of teachers and university chemists, it is designed to be accessible to Year 12 students but will take them significantly beyond the syllabus and encourage them to think about science in the way they would at university. Past papers will provide a valuable resource for teachers. This competition is open to students studying in the UK in Year 12 (Lower 6th) or below. It will take the form of a 90 minute written paper which students will take at school. Details for registering for the 2013 competition will be posted nearer the time and specimen questions are available here. Students who do well in the competition will be sent certificates of achievement, and those who perform best will win an invitation to a residential camp at the University of Cambridge at the end of August.
| To promote the competition, we have sent to all schools in the UK an A1 interactive poster. It shows the flame test colours for nine common metal ions as first featured in a demonstration lecture on Group 1 of the Periodic Table available for free here. With the aid of a smart phone or iPad and the app from Zappar, the poster can be brought to life! If your school has not received one or you would like further copies, please email poster@C3L6.com with your full school postal address. |  |
