The Department aims to teach Chemistry in a way that stimulates students, allowing them to enjoy the classes. We provide an opportunity to become familiar with a range of chemical concepts and ideas, placed as much as possible in the real world.

Welcome to the Chemistry Department 

We discuss a range of topics and do a number of appropriate experiments, through which the students learn about Chemistry in particular as well as about general skills such as independent thinking, taking initiative and critical observation. These skills are developed and expanded upon as the students progress from U3 through U5. For those who are keen to take Chemistry through A-level we provide AS and A level classes, challenging the students to venture beyond knowledge and skills acquired thus far.

Staff List

Mrs Nicola Austin- Head of Chemistry
Joined St Catherine's in 2007. Prior to this she had spent a year researching the application of mass spectrometry to the study of proteins, and in particular the protein responsible for the body’s response to a lack of oxygen. Applications of spectrometry and spectroscopy remain an area of interest. Outside of school she enjoys travelling, especially in South East Asia, and sampling different local cuisines. She also likes to experiment with different recipes in the kitchen.

Before this she had a career as a Biomedical Scientist specialising in clinical biochemistry in hospital laboratories.  Latterly she was employed by NICE testing the efficiency and quality of medical devices and writing research papers on CE marking of medical devices. Extra-curricular interests include taking part in the school Association choir supporting St Helens RLFC and Liverpool FC and walking her dog in the Surrey hills.

Curriculum - AS/A Level

Examination Board: Edexcel

AS Specification

A-Level Specification  

Why study Chemistry?

One of the first things that you will notice as you progress through to A Level is that some of the ideas that you took for granted at GCSE level have more to them than you thought. As you gain a deeper understanding of the underlying principles involved, you will start to see how all the many and varied aspects of the subject are held together. The ability to apply your mind in this way is very highly valued in the wider world, hence why Chemistry students rarely find difficulty in obtaining employment.  Studying A Level Chemistry will allow you to discover more about the fascinating world we live in and the science behind major technological developments. 

Course Content

AS Level:  You will study many topics covered at GCSE level in more depth. These include atomic structure, energetics, rates and amounts of substance. You will also study the foundations of Organic Chemistry and analytical techniques.

A Level: You will learn a wider selection of reactions in Organic Chemistry and how they can be used to synthesise everything from pharmaceuticals to fabrics. You will study analytical techniques with a wide range of applications including forensics, medicine and in industry. Physical Chemistry topics are developed and mathematical techniques are applied to predicting whether reactions occur, interpreting pH and analysing rates information. The colourful world of transition metals and their applications to modern day life are also explored.

16 core practical are integrated into the two year course and you will have ample opportunities to develop your understanding of experimental methods and practical skills.


  • AS Level: 2 x 1 hour 30 mins papers
  • A Level: 2 x 1 hour 45 mins papers and 1x 2 hours 30 mins paper
    At A Level there is also a teacher assessed practical competency. This will be reported separately to your A Level grade.

Curriculum - IGCSE

We begin teaching IGCSE in U4. We follow the Edexcel IGCSE specification. During the course of the U4 year the girls choose whether they would like to take Dual Award Science or Separate Science. All of the material that is taught in the U4 is on the Dual Award Specification.

The IGCSE course has recently been reformed so the specification being taught will depend on the year in which a girl is going it sit the examination.

IGCSE Chemistry Specification

Below is a list of the topics studied each year, although there may be subtle changes from time-to-time. 


  • States of Matter
  • Atomic structure
  • Structure and Bonding – Ionic and Covalent
  • The Periodic Table
  • Group 1 – Alkali Metals
  • Group 7 – The Halogens
  • Group 0 - The Noble Gases
  • Oxygen and Air
  • Separation Techniques


  • The Reactivity Series
  • Acids, bases and making salts
  • Organic Chemistry
  • Energetics
  • Identification

Separate scientists will study some additional material on making salts and organic chemistry. They will also study some additional topics including metallic bonding and the extraction of metals.


  • Rates of reaction
  • Mole calculations
  • Structure and Bonding
  • Reversible Reactions

There will also be some time allocated to revision and consolidation.

Separate scientists will study some additional material on mole calculations. They will also study some additional topics including equilibrium and electrolysis.

Curriculum - KS3

The programme of study taught in Middle School Chemistry lessons is designed to offer students opportunities to enjoy and explore a broad range of topics whilst ensuring that they develop both their scientific skills and key understanding of core concepts in preparation for taking IGCSE. We aim to relate the material taught to the world around us and to highlight everyday applications, including recent developments. Students have the chance to develop their practical skills and gain confidence in applying the scientific method.

U3 Chemistry

In U3 we start the year with a discussion on chemical safety and some demonstrations of what can happen if a corrosive or flammable substance is not handled correctly. Topics following that include:

  • Particle Theory
  • Separation
  • Chemical and Physical Changes
  • Acids and Alkalis.

L4 Chemistry

  • Atoms, Elements and Compounds
  • Chemical reactions
  • Smart materials and Nanotechnology
  • Carbon, fuels and the future


RSC Chemistry Olympiad

For the last few Upper Sixth girls entered the International Chemistry Olympiad. This is a challenging written test of chemical knowledge. The questions are based on real-world chemistry problems and recent news. They provide a good opportunity to develop some of the skills required for study at university and beyond.

Our girls have achieved some very commendable results, including Silver Awards.

Cambridge Chemistry Challenge

At the end of the Lower Sixth year girls studying Chemistry have the opportunity to enter the Cambridge Chemistry Challenge.

The aims of this competition are similar to the Chemistry Olympiad: to stretch and challenge students interested in Chemistry. It provides an excellent experience for anyone considering taking their studies further.

Our girls have achieved some very commendable results in the competition, including Silver Awards.

Over the years some interesting online challenges have also been posted on the Cambridge Chemistry Challenge. We encourage students to have a go at completing some to develop their thinking and reasoning skills. The online challenges can be accessed here.

Sixth Form Science Club

The Sixth Form Science Club provides an opportunity for Sixth Form students to complete Crest projects which are beyond the scope of the A-Level specification. They can increase their confidence in the manipulation of a range of chemicals and pieces of apparatus and gain experience of different techniques. It also provided the opportunity for students to carry out more investigative and independent work.
