The study of matter, its properties, how and why substances combine or separate to form other substances, & how substances interact with energy.

Chemistry is all around us – not just in the laboratory. Chemical reactions are occurring daily – when you drive a car, light a fire, bake a cake and digestion in your body to name but a few!

Chemistry is a hands’ on, interactive subject. During your two-year study of Leaving Cert Chemistry, you will complete 28 mandatory experiments. This gives any student the necessary skills associated with laboratory techniques and scientific writing.

Leaving Certificate Chemistry will provide a stable foundation for any student who wishes to continue with Science related subjects after the completion of their Leaving Certificate.

Subject Overview

Chemistry is a subject that requires very active participation which includes many experiments, calculations and real-life applications. Chemical reactions are all around us and understanding chemistry helps us make sense of the world around us.

As a Leaving Certificate science subject, the syllabus is designed to incorporate the following components:

  • Science for the enquiring mind, or pure science, to include the principles, procedures and concepts of the subject as well as its cultural and historical aspects.
  • Science for action, or the applications of science and its interface with technology.
  • Science, which is concerned with issues - political, social and economic – of concern to citizens.

The Chemistry syllabus is offered at two levels; Higher and Ordinary level. Students will have approximately 180 hours class contact time over a two year period. The teaching is both practical and experiment based.
