Course Description
This course furthers students’ understanding of the processes that occur in biological systems. Students will study theory and conduct investigations in the areas of biodiversity; evolution; genetic processes; the structureandfunctionofanimals;andtheanatomy,growth,andfunctionofplants.Thecoursefocuseson the theoretical aspects of the topics under study, and helps students refine skills related to scientific investigation.
Outline of Course Content


Titles and Descriptions

Time   and Sequence

Unit 1


In this unit, students will demonstrate an understanding of the theory of evolution and the evidence that supports it. They will examine the mechanisms by which it occurs, including thorough consideration of natural selection and punctuated equilibrium, and evaluate the logic that has drawn scientiststo their conclusions. They will also analyse the economicand environmental pros and cons of artificial selection technology, and evaluate the impact of environmental changes on natural selection and species atrisk.

22 hours

Unit 2

Diversity of Life

In this unit, students will demonstrate an understanding ofthe diversity of living things through the principles of taxonomy and phylogeny. They will use sampling and classification techniquestoinferphylogeniesandheredity.Theywillanalyse the effects of human activity onbiodiversity.

22 hours

Unit 3

Genetic Processes

In this unit, students will demonstrate an understanding of concepts, processes, and technologies related to the transmission of hereditary characteristics. They willinvestigate genetic processes, including but not limited to mitosisand meiosis, and solve basic classical genetics problems involving monohybrid and dihybrid crosses. They will consider the importance of recent contributions to our knowledge of genetics, and consider the impact and implications of genetic, genomic and proteomicresearch.

22 hours


Animals: Structure and Function

In this unit, students will demonstrate an understanding of animal anatomy and physiology, and describe disorders of some major organ systems. They will investigate by means of computer simulation and independent experimentation, the functionalresponsesoftherespiratoryandcirculatorysystems of animals, and the relationships between majororgan systems. They will analyse the relationships between changing societal needs, technological advances and our understanding of internal systems of humans, including detailed studies of some modern heartsurgeries.



Plants: Anatomy, Growth and Function

In this unit, students will demonstrate an understanding ofthe diversity of vascular plants, including but not limited to their structures, internal transport systems, reproductive cycles, roles in evolution, and roles in creating and maintaining biodiversity in the context of ecological succession and climax communities.Theywillinvestigatethestructuresandfunctions ofplanttissuesthroughlaboratoryexercises.Theywillconsider the importance of the sustainable use of plants tosociety.

Final Evaluation

The final assessment task is a three hour exam worth 30% of the student’s final mark.
