Biology - 11-Grade: 11

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 structure and function of animals; and the anatomy, growth, and function of plants. The course focuses on the theoretical aspects of the topics under study, and helps students refine skills related to scientific investigation.

Unit Titles and Descriptions

Time Allocated

Diversity of Living Things

In this unit, students will demonstrate an understanding that all living things can be classified through the principles of taxonomy and phylogeny. They will use sampling and classification techniques to investigate the principles of scientific classification. Students will analyse the effects of human activity on the diversity of living organisms in ecosystems.

22 hours


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 scientists to their conclusions. Students will also analyse the economic and environmental implications of artificial selection technology and evaluate the impact of environmental changes on natural selection and species at risk.

22 hours

Genetic Processes

In this unit, students will evaluate recent advances in our knowledge of genetic processes and demonstrate an understanding that genetic and genomic research can have both social and environmental implications. They will investigate how variability and diversity of living organisms results from the distribution of genetic material during the process of meiosis.  Students will also analyse data to solve basic genetic problems.

22 hours

Animals: Structure and Function

In this unit, students will demonstrate an understanding of how groups of organs with specific structures and functions work together as systems, which interact with other systems in the body. They will investigate by means of computer simulation and independent experimentation, the functional responses, and relationships between major organ systems. Students will also be asked to consider how the development and uses of technology to maintain health are related to the changing needs of society.

21 hours

Plants: Anatomy, Growth and Function

In this unit, students will demonstrate an understanding that plants have specialised structures with distinct functions that enable them to respond and adapt to their environment.  They will investigate the structures and functions of plant tissues and factors affecting growth. Students will consider the importance of the plant variety to the survival and sustainability of ecosystems.
