'The scientific study of living things from the molecular level to their interactions with one another and their environments.'
'The three main reasons for taking Life Sciences are:
to provide useful knowledge and skills that are needed in everyday life
to expose learners to the scope of biological studies to stimulate interest in and create awareness of possible specialisations; and
to provide a sufficient background for further studies in one or more of the biological sub-disciplines' - South African Department of Education CAPS
For the period from Grade 10 to Grade 12, a learner can expect to learn about life at the molecular, cellular, and tissue level; life processes in plants and animals; environmental studies and diversity, change, and continuity.
