CHEMISTRY (OCR)

AS Course Outline

What is Chemistry?

Chemistry is the study of the composition and reactions of all substances. Chemists explain their observations of the nature and behaviour of substances in terms of the structure and arrangement of their particles: atoms, molecules or ions.

Such examples include: why certain compounds can be used to make large scale explosives. Why and how the development of new technology can reduce the effect of global warming.

The new AS level syllabus includes material intended to enhance the understanding of contemporary issues which are frequently in the media

This includes 'green' chemistry, fuel cells for powering electric vehicles, chemotherapy treatments and other pharmaceuticals.

Which degree courses will Chemistry enable me to study at University?

• Chemistry is essential for Medicine, Dentistry, Veterinary Science, Pharmacy, Forensic Science, Biomedical Sciences and Chemistry degrees. Chemistry provides a means for students to develop intellectual skills alongside manipulative, observational, evaluative and general problem-solving skills.
• It is a preferred qualification for many courses and is even advantageous for degree courses in Law, Economics and Accounting.

What do I need for the course?

• At least a grade C in GCSE Chemistry or CC in Double or Dual Award Science is essential, but higher grades would be preferable.
• A good understanding of Maths including:
  The manipulation of algebraic expressions
  Collating and displaying data in a graphical form.

Structure of the Course

One lesson each week is dedicated to practical work, and practical skills will be developed and assessed in these lessons. Homework is set after each class and is an essential part of the course. Mock exams take place once a month..
