Course Outline


Cambridge International Advanced Level A2 course at GEMS Wesgreen International School builds on the skills acquired at Cambridge AS (or equivalent) level. The syllabus includes the main theoretical concepts, which are fundamental to the subject, some current applications of chemistry, and a strong emphasis on advanced practical skills.

The emphasis throughout is on the understanding of concepts and the application of chemistry ideas in novel contexts as well as on the acquisition of knowledge. The course encourages creative thinking and problem-solving skills, which are transferable to any future career path. Cambridge International AS and A Level Chemistry is ideal for learners who want to study chemistry or a wide variety of related subjects at university or to follow a career in science like medicine, engineering etc.

Learning Outcomes

The aims of all subject's state what a teacher may expect to teach and what a student may expect to experience and learn. These aims suggest how the student may be changed by the learning experience.  

The aims of the Science Syllabus are to encourage and enable students to: 

  • develop scientific knowledge and conceptual understanding through the specific disciplines of biology, chemistry and physics .
  • develop understanding of the nature, processes and methods of science through different types of science enquiries that help them to answer scientific questions about the world around them.
  • are equipped with the scientific knowledge required to understand the uses and implications of science, today and for the future. 

Ongoing Objectives

Our mission at Gems Wesgreen International School is to provide educational benefit through provision of programs to develop learners who are:

        •   confident in working with information and ideas – their own and those of others

        •   responsible for themselves, responsive to and respectful of others

        •    reflective as learners, developing their ability to learn

        •   innovative and equipped for new and future challenges

        •   engaged intellectually and socially ready to make a difference.

Unit Overviews

The A2 course shall be covered in one academic year and shall involve covering the contents in the AS and A level Chemistry syllabus, which are: Physical Chemistry, Inorganic Chemistry and Organic Chemistry. 

Term 1

Approximate length: 12weeks 

For blended learning we will provide video links, live demonstrations of practical investigation as well as access to the relevant worksheets and resources that all students will need.

A.  Physical Chemistry                                

Physical chemistry is the study of how matter behaves on a molecular and atomic level and how chemical reactions occur. Based on their analyses, physical chemists may develop new theories, such as how complex structures are formed. Physical chemists often work closely with materials scientists to research and develop potential uses for new materials. Unlike other branches, it deals with the principles of physics underlying all chemical interactions (e.g., gas laws), seeking to measure, correlate, and explain the quantitative aspects of reactions.

Physical chemistry has traditionally given students broad training, and positioned them to work in a variety of scientific careers.

Physical chemistry

1. Lattice Energy

2. Entropy change

3. Electrolysis

4. Electrode potentials

5. Ionic equilibria

6. Partition coefficients

7. Reaction rate

8. Inorganic chemistry: Group 2

9. Transitional metal chemistry

Specific National Curriculum Objectives Covered:

5 Lattice Energy/Entropy

  • explain and use the term lattice energy (ΔH negative, i.e. gaseous ions to solid lattice)

6 Electrochemistry

  • state and apply the relationship F = Le between the Faraday constant, the avogadro constant and the charge on the electron

7 Equilibria

  • explain the terms pH, Ka, pKa and Kw and use them in calculations

8 Reaction kinetics

  • explain and use the terms rate equation, order of reaction, rate constant, half-life of a reaction, rate-determining step.

12 an introduction to the chemistry of transition elements

  • explain what is meant by a transition element, in terms of d-block elements forming one or more stable ions with incomplete - d orbitals.

Term 2

Programme of Study


Formative: Throughout the units, the students will complete graded work, quizzes and investigation activities, which allows the teacher to assess the students’ attainment and inform their planning.  

For each unit the student's complete topic test. This allows us to see progress across the units and to inform our planning.   

Summative: At the end of term 1, we complete internal tests and mock examinations at the end of the second term. The end of Term Tests and the mock examinations will test students in Papers 1, 2 and 3 as per the AS and A level syllabus.
