A-Level chemistry students have been hard at work devising and writing up experiments which will count towards a third of their coursework marks. The experiments have included iodine and bromine clock reactions where students had to gauge why and how a reaction takes place, to making and analysing paracetamol for purity and using a complex system of steam distillation to determine fluctuations in the acidity level of a fermented liquid.
The Year 13 students carried out their practical tasks over a four-week period, using all their allocated lesson time and often continuing research in their free time so that they had enough information to write up their findings.
Head of Science, Mr Paul Knight said: 'They've had a bit of advice on what to choose, they've gone away and researched it, developed the methods, made up the solutions and ordered in equipment themselves. It's totally independent work. We have had to order a few chemicals in especially for these projects. This year group have been very conscientious and have carried out some very interesting and exacting experiments.'
