Huvitav kiri

Dear student,

I thought you might be interested in this new website we have just developed for the launch of the International Year of Chemistry. It is a new competition for students (or anyone else) and consists of 5 questions that students need to solve using whatever means they like – such as google, or Wikipedia, or whatever.

You can only get on to the next question once the first is solved. If you get through all five levels, their name will appear on the Cambridge Chemistry Challenge Honours Board. So far there are students from all round the world, but none yet from Estonia I think. It would be nice for you to join in too.

I hope you have fun with this – there will be new questions on the first day of each month to keep you interested.

With best wishes,
