LIFE SCIENCES (Updated October 2022)

LIFE SCIENCES: ASSESSMENT SYLLABUS

INTRODUCTION TO LIFE SCIENCES

Establish links between Natural Sciences (GET) and Life Sciences (FET). Define life, its scope, and its continuity. Life on earth is dynamic, with
homeostasis maintaining balance at every level of organisation. Life is characterised by change over billions of years. Living systems exhibit levels
of organisation from molecules to biomes.

How science works:
• Fundamental knowledge built on scientific evidence
• Observation
• Designing an investigation
• Making measurements and the importance of scaling
• Presenting data in the form of drawings, written descriptions, ta bles and graphs.
• Identifying patterns and relationships in data • Societal aspects of scientific evidence
• Limitations of scientific evidence.

The contested nature of scientific knowledge:
• Testing hypothesis (educated predictions) by means of investigations,
• facts as what structures/objects consist of/are made of,
• scientific theories as overarching explanations of how processes/mechanisms work,
• peer verification by means of publications, conferences, verifying results

GRADE 10

STRAND: Environmental Studies
Grade 10: Biosphere to ecosystems
Organisms interact with other organisms and with the environments in which they live in order to survive and produce offspring. The study of these
interactions is called ecology. This section is structured so as to expose students to some of the interactions that occur in nature and to the
terminology and concepts that describe them. The terminology and concepts selected here (AIM 1) will be used in Grade 11 and Grade 12 across
all strands, where appropriate. It also enables students to contextualise the meaning of these terms and concepts within the familiar contexts of
both southern Africa (AIM 1) and their local area (AIM 2). The use of a local area context is also used to introduce human influences on the
environments in which they and other organisms live (AIM 3), a thread which will be expanded on both within local and global contexts, in more
detail, in Grade 11.

STRAND: Diversity, change & continuity
Grade 10: History of life and biodiversity
Underlying concept: Life exists in a huge array of forms and modes of life at present, which scientists organise according to a man-made
classification system. Modern life has a long history, extending from the first cells around 3.5 billion years ago. South Africa has a rich fossil record
of some key events in the history of life. Changes in life forms are related to climate changes and movements of continents and oceans over long
periods of time.
