An exploration of applied science

This qualification is aimed at students who want to continue their education through applied learning and who aim to progress to higher education and ultimately to employment, possibly in the applied science sector. The qualification is equivalent in size to one A-level.


The course

Mandatory elements are:

  • Principles and applications of science I.
  • Practical scientific procedures and techniques.
  • Science investigation skills.

Then students will study one of the following units:

  • Physiology of human body systems: the physiological make up of three human body systems (musculoskeletal, lymphatic and digestive), how the systems function and what occurs during dysfunction.
  • Human regulation and reproduction: how the internal body environment is regulated and controlled within set parameters to enable key bodily process to take place.
  • Biological molecules and metabolic pathways: biological molecules and the metabolic pathways involved in chemical reactions to enable organisms to function normally.
  • Genetics and genetic engineering: the structure of DNA, cell division and the principles of Mendelian genetics and variation.
  • Diseases and infection: five types of diseases, their causes and how humans try to prevent and treat them.
  • Applications of inorganic chemistry: acid-base equilibria, redox reactions and transition metal complexes.
  • Applications of organic chemistry: develop an understanding of the properties and uses of organic compounds their properties and uses in everyday life.
  • Electrical circuits and their application: the principles of electricity, including measurements of electrical values and health and safety, the construction of circuits and their use in society today.
  • Astronomy and space science: the principles and present-day understanding of developments in astronomy.


Beyond the classroom

The Science Department is very active, running numerous clubs and activities for students across all years.



The subject can give context to subjects which would benefit from some scientific background.

For example, with:

  • A-levels such as Maths and Physics  to progress to engineering related courses.
  • A-level in Psychology and BTEC in Sport to progress to sport psychology courses.
  • BTEC in Health and Social Care to progress to nursing courses.
  • A-levels in Geography and Computing to progress to geography or environmental science courses.
