Chemistry

The Chemistry department aims to teach the fundamentals of the subject to make the pupils aware of the scientific world around them and to understand how this world affects them. It aims to teach the fundamentals of scientific enquiry so that the boys are able to make reasoned decisions on scientific matters as information is presented to them. Chemistry is a key subject to anyone thinking of pursuing a career in Medicine or Biological Sciences, Natural Sciences or any of a number of diverse subjects from Archaeology to Accountancy.
The department uses four customised laboratories containing the latest in computer presentation equipment. There is sufficient room in the laboratories to allow up to thirty boys to carry out their practical work which reinforces the theoretical work studied. It also gives them the confidence to investigate the material world around them.

Key Stage Three
The first two years are spent learning the basics of the subject and preparing for the Science SATS examinations. Expectations are set above and beyond the constraints of the National Curriculum.

Key Stage Four
Chemistry is studied by most boys as a separate subject to GCSE, following the AQA GCSE Chemistry syllabus; there is the option to choose to study for AQA Science an Advanced Science instead. The GCSE course is spread evenly across three years (years 9, 10 and 11), each year involving continuous preparation for the examination. The course is supported by frequent practical work in the customised laboratory facilities.
Syllabus Details:
Chemical reactions and equations are introduced at relevant points throughout the three years. Otherwise the distribution of topics is:
Year 9: Atomic structure; Rates of reaction; Earth and atmosphere; Limestone chemistry.
Year 10: Properties of materials; Metals and ores; The periodic table; Crude oil; Ethanol and polymers; Plant oils; Moles and reversible reactions; Analysis.
Year 11: Energy and calculations; Solutions and electrolysis; Acids and bases; Water.

Key Stage 5
The course (AQA Chemistry Syllabus) throughout the Sixth Form builds on the ideas and knowledge laid down during the GCSE years. A good grasp of fundamental principles involved in the subject is highly important. The factual base of the subject is supported by practical work, and by an emphasis on experimental evidence that backs up our knowledge and understanding of the subject.

Chemistry at this level is likely to appeal to those who enjoyed the subject through the lower School and who coped with the demands of the GCSE course. Although some mathematics remains in the course, this is now mostly confined to the A2 units. The mathematical principles involved tend to involve basic numeracy and ability to rearrange equations, plot graphs, estimate accurately and so on, rather than knowledge of mathematical techniques.

Lower Sixth
A more detailed look at many familiar topics from GCSE: atomic structure, bonding, the Periodic Table. In addition, organic chemistry is widened to examine a larger array of carbon-based molecules; and topics such as energy, kinetics and equilibria are also broadened to consider more qualitative aspects, as well as practical applications. There are three exam units, one of which includes practical coursework similar to GCSE but with students working individually and with no requirement for complete investigations. The coursework counts for 20% of the marks at both AS and A2.

Upper Sixth: This course seeks to provide a much deeper understanding of the topics encountered at AS level. As well as further study of organic molecules, topics in physical chemistry such as kinetics and equilibrium are dealt with quantitatively. In addition the colourful world of transition metal chemistry is encountered and modern laboratory techniques for analysis are also investigated. As well as coursework, the third exam unit also examines synoptic elements of the whole two year course.
