Chemistry

Chemistry is a practical subject and laboratory skills and techniques are developed within a framework, which pays due regard to health and safety and promotes an awareness of their uses and limitations. It is hoped to develop positive pupil attitudes through success and enjoyment of the subject. 

IGCSE 

The Cambridge IGCSE Chemistry syllabus (0620) is a linear course and is studied over three years. It is a demanding course with a significant practical component and it develops good analytical skills and emphasises the use of Mathematics as a tool to solve problems. It is perhaps a more traditional course than other IGCSE level courses and demands decent algebra skills and the ability to memorise and make use of fundamental formulae. Although this is quite demanding it is excellent preparation for studying Chemistry at IB. All students start the Chemistry IGCSE course, but can opt instead for Coordinated Science during the Middle Fifth.

The syllabus itself consists of 20 topics and each one is divided in to a core and extended curriculum. Students entered for a higher tier examination are taught both, whereas those being entered for a paper only follow the core curriculum.

The students are assessed at the end of Upper Fifth by written examinations and a practical examination, though it is possible if students prefer to do the alternative to practical exam.

ASSESSMENT:

All students use the same textbook 'Essential Chemistry for Cambridge IGCSE', Roger Norris published by Nelson Thornes.

Students are always encouraged to ask their teacher for help if needed but they can also attend the Chemistry clinic, which is run on Monday lunchtimes from 1345 until 1410.

IB 

AIMS

The IB Chemistry course is designed to increase pupils’ knowledge and understanding of the subject, their ability to solve problems and their practical and investigative abilities; to deal with abstract and theoretical material; increase their knowledge and understanding of the social and economic importance of Chemistry; foster independent study, practical work and research as well as prepare pupils for further study and employment.

QUALIFICATIONS NECESSARY

It is assumed that everyone coming into the Sixth Form to study IB Chemistry will have a IGCSE in the subject or in Coordinated Science or an equivalent level of achievement. Pupils who have only achieved a C grade may find some aspects of the course difficult. A certain amount of mathematical knowledge is required but this is not excessive and students will be taught to the required standard.

THE IB CHEMISTRY COURSE

The IB Chemistry course is offered at both the Standard Level and Higher Level. The course itself is split into five basic sections; the subject specific core (topics 1 to 11), the additional Higher Level material (topics 12-20), the optional units (A to D), Internal Assessment and the Group 4 project. The core material provides a solid foundation on which the remainder of the course is built.  The additional Higher Level work explores some of the work already covered in the core topics but in a much greater depth. There are four optional units available and those offered will be specific to the expertise of the staff.

SL and HL Options
Topic 1: Stoichiometric Relationships
Topic 2 &12: Atomic Structure
Topic 3 & 13: Periodicity
Topic 4 & 14: Chemical Bonding and Structure
Topic 5 & 15: Energetics and Thermochemistry
Topic 6 & 16: Chemical Kinetics
Topic 7 & 17: Equilibrium
Topic 8 & 18: Acids and Bases
Topic 9 &19: Redox Processes
Topic 10 & 20: Organic Chemistry
Topic 11: Measurement and analysis
Option A – Materials
Option B – Biochemistry
Option C – Energy
Option D - Medicinal Chemistry

ASSESSMENT

External Assessments take place at the end of two years: students are examined using multiple choice questions as well as data-based, short answer and long answer questions. Weighting: 80% at Higher and Standard Level.

Standard Level students have to complete 40 hours and Higher Level students have to complete 60 hours of Internal Assessment, including 10 hours on a collaborative interdisciplinary project with other Group 4 Sciences. Students are expected to design experiments, carry out experiments, analyse results and come to conclusions supported by the data.  Weighting: 20% at Higher and Standard Level.

I loved King William’s College from the start. I made up my mind within an hour of our time there that I wanted my son to attend. You have to come to College to understand what makes it stand out from the rest. It is a place of genuinely caring and friendly people. Another aspect of College we love is its vast international community. Our son has made some great friends and as a result has come to appreciate and respect other cultures and traditions. Our son loves College. He loves the independence to make choices, the easy access he has to his tutors, the opportunity to make his own mistakes and learn from them, but most of all, he loves the fact that expert assistance is always a breath away.
