Life Science is the scientific study of living things from molecular level to their interactions with one another and their environments.
It encourages an enquiring mind and provides useful knowledge and skills which are needed in everyday life. Life Science provides stimulation of interest which may lead to areas of specialisation at tertiary level.
Who should opt for this subject?
Boys who are interested in all forms of life and their scientific study should choose this course. Those who want to know more about the human body and its functions, and who have an appreciation of the environment and current issues such as new discoveries, should consider Life Science as an option. The average boy copes with it if he is willing to spend time studying, as there are no short-cuts. It is a very content-based subject and a considerable amount of written information is needed, so a sound work ethic is vital. It suits the organised mind as well-kept files are an advantage. A good grasp of English also stands a boy in good stead.
Good skills the boys learn are:
- the selection of key ideas
- factual recall
- understanding of concepts
- application of information
- to critically evaluate and debate scientific issues
- greater awareness and appreciation of the environment and ecosystems that sustain everyday life

A favourite aspect of Life Science is the practical work, involving food tests, microscope work, dissection of various organs, and the study of the skeleton. Debates around evolution are also stimulating and thought-provoking.
The year mark is comprised of 3 practical tasks, a minimum of 4 class tests, a project, and 1 June Exam. This total mark counts 25%. The November Exams (2 Theory & 1 Practical) make up the remaining 75%. (The Grade 12 pupils write Trials in addition to these tasks).
