Chemistry

Why Chemistry?

Chemistry opens up a world of possibilities and expands your career choices to all sorts of jobs that you may have never even imagined! In our ever changing world Chemistry will always be at the heart of new developments. From the food we eat to the clothes we wear and the technology we use – it all involves Chemistry. Do you want to have a better understanding of the world we live in?

How to develop new materials and medicines? How to control global warming and monitor or protect our environment? How to safeguard our food supply?

Chemistry enables you to appreciate how society makes decisions about scientific issues and how these contribute to a successful economy. Is Chemistry the right choice for your future?

Summary of content

The WJEC A level in Chemistry provides a broad, coherent, satisfying and worthwhile course of study. It encourages learners to develop confidence in, and a positive attitude towards, chemistry and to recognise its importance in their own lives and to society. Learners will develop an understanding of how society makes decisions about scientific issues and how the sciences contribute to the success of the economy and society.

Practical work is an intrinsic part of chemistry, and is greatly valued by higher education. It is imperative that practical skills are developed throughout the course and that an investigative approach is promoted wherever possible.

10% of qualification

This unit gives learners the opportunity to demonstrate their skills, knowledge and understanding in relation to practical techniques and their ability to analyse and evaluate experimental data. The practical examination comprises two tasks to be carried out individually under controlled conditions:

  • Experimental Task (30 marks)
  • Practical Methods and Analysis Task (30 marks)

Go to Appendix B of Spec. for details of practical techniques [page 53]. Go to Appendix C of spec. for details of mathematical requirements [page 56].
