Biology is the science of living things and can be categorised broadly into the study of animals and plants and micro-organisms.  This section of thesyllabus deals with aspects of human biology and plant biology. The human body is an integrated organism, with a variety of systems that carry out a range of functions. Each system has a particular structure that enables it to carry out its functions. Understanding how the body functions and how it develops will enable us to appreciate the processes and changes that occur during our lives. Plants and micro-organisms are a vital component of our living world. Plants are the main food producers for all living things.


The world is made up of a variety of substances. Some of these occur naturally in our environment, others are made through the combination of naturally occurring substances to form new materials. The study of chemistry can lead us to a better understanding of our material world and the processes by which materials can change and be changed.


Physics is involved in most of the everyday applications of science and technology that we meet in our daily lives, in work, medicine, entertainment and in the home. While physics is principally concerned with the laws and relationships that govern our world, it also provides interesting insights into how things work and contributes to the development of problem-solving skills.
