Chemistry

Welcome to the Chemistry pages of our website.   Throughout the senior school programme we try to teach the subject as practically as possible.  Chemistry is taught as part of our integrated science course in Key Stage 3.  In year 9 of the key stage the Biology, Chemistry and Physics parts of the course are taught by different teachers usually subject specialists.  In years 10 and 11 Chemistry is an option and the syllabus studied is the Cambridge IGCSE course.  In the sixth form Chemistry can again be studied to AS and A2 level with Cambridge examinations at the end of the course.

See IGCSE, AS and A2 sections on the related links on the right menu.

 

 

AS & A2 Chemistry Syllabus      
 

Syllabus Details

Students, at Greensteds School, study the Cambridge General Certificate of Education International Advanced (A2) Level and Advanced Subsidiary (AS) Level Syllabus.

In the first year (AS Level) the following areas are studied:

 

Physical Chemistry   

Inorganic Chemistry 

 Organic Chemistry

 Atoms, Molecules and Stoichiometry;  

 Chemical Periodicity;

 Introductory Topics

 Atomic Structure; 

 Group II

 Hydrocarbons

 Chemical Bonding;  

 Group VII

 Halogen Derivatives

 States of Matter;  

 Nitrogen and Sulphur

 Hydroxy Compounds

 Chemical Energetics;

 

 Carbonyl Compounds

 Electrochemistry; 

 

 Carboxylic Acids and their Derivatives

 Equilibria; 

 

 Polymerisation

 Reaction Kinetics.

   
     
     

Chemistry PracticalsIn the second year (A2 Level) the above areas are studied to greater depth and the following areas are added:

Group IV; Transition Elements; Arenes and Nitrogen Compounds.

In addition, students study three Applications of Chemistry:

*Chemistry of Life
*Applications of Analytical Chemistry
*Design and Materials

About Chemistry

Chemistry is a vital subject for those students wishing to pursue a career in the medical industry.  However the aims of this syllabus make Chemistry a versatile and useful subject for a wide range of applications, both everyday and career orientated.

The aims of the syllabus are to:

  • provide, through well designed studies of experimental and practical chemistry, a worthwhile educational experience for all students, whether or not they go on to study science beyond this level and to enable them to become confident citizens in a technological world, able to recognise the usefulness and limitations of scientific method (appreciating it’s applicability in other disciplines and everyday life) and be suitably prepared for employment/further studies.

  • develop abilities and skills that are relevant to the study and practice of science, are useful in everyday life, encourage safe and efficient practice, encourage the presentation of ideas appropriate for different audiences/purposes and develop self motivation and the ability to work in a sustained fashion.

  • develop attitudes relevant to science such as accuracy and precision, objectivity, integrity, enquiry, initiative and insight.

  • stimulate interest in, and care for, the environment.

  • promote an awareness that the applications of science may be both beneficial and detrimental to the individual, the community and the environment, and that the use of IT is important for communication, as an aid to experiments and as an interpretation tool.

  • stimulate students, create and sustain their interest in Chemistry, and understand its relevance to society.

 

IGCSE Chemistry

The syllabus used is Cambridge IGCSE (0620), it split into the following topics:

  • The Particulate Nature of Matter
  • Experimental Techniques
  • Atoms, Elements and Compounds
  • Stoichiometry - concerned with measuring the proportions of elements that combine when reactions take place
  • Electricity & Chemistry
  • Chemical Changes
  • Acids, Bases & Salts
  • The Periodic Table
  • Metals
  • Air and Water
  • Sulphur
  • Carbonates
  • Organic Chemistry
Scheme of Assessment

The assessment consists of:
 


Core curriculum
Grades C to G

Extended curriculum
Grades A* to G

Paper 1 (45 minutes)
Forty multiple choice questions on the core curriculum with A to D responses.
Weighted to give 30% of the total mark.

Paper  2 (1 hour 15 minutes)
Core theory paper consisting of short answer and structured questions giving 80 marks.  The questions are based on the core curriculum.  It is weighted to give 50% of the total mark.

Paper  3 (1 hr 15 minutes)
Extended theory paper consisting of short answer and structured questions giving 80 marks.  The questions are of a difficulty appropriate to the higher grades.  A quarter of the marks are based on the core curriculum the remainder from the supplementary material.  .  It is weighted to give 50% of the total mark.

Paper 5 – (1 hour 15 minutes)
A practical test with questions covering experimental and observational skills.
The paper is weighted to give 20% of the total mark.

 

It is strongly recommended that any student wishing to progress to “A” level has studied the extended course and achieved a C or above in their IGCSE.
