Biology SBI4U


This course provides students with the opportunity for in-depth study of the concepts and processes that occur in biological systems. Students will study theory and conduct investigations in the areas of biochemistry, metabolic processes, molecular genetics, homeostasis, and population dynamics. Emphasis will be placed on the achievement of detailed knowledge and the refinement of skills needed for further study in various branches of the life sciences and related fields.

SKU: SBI4U Category:

The SBI4U Biology course is designed for Grade 12 students preparing for university studies in biology and other science-related fields. This course provides a comprehensive understanding of biological systems and the complex interactions that drive biological processes.

Course Overview

Students will explore five key units: Biochemistry, Metabolic Processes, Molecular Genetics, Homeostasis, and Population Dynamics. This program integrates concepts from chemistry, physics, and earth science to foster a multidisciplinary approach to understanding biological phenomena.


Successful completion of Biology, Grade 11, University Preparation (SBI3U) is required.

Key Learning Objectives

  • Develop a deep understanding of biochemical processes and their applications in various biological systems.
  • Analyze metabolic pathways and their roles in energy production and consumption within cells.
  • Investigate the principles of molecular genetics, including DNA replication, protein synthesis, and genetic engineering.
  • Examine mechanisms of homeostasis and their importance in maintaining physiological balance within organisms.
  • Study population dynamics to understand ecological relationships and environmental impacts on living organisms.

Course Goals

This course aims to prepare students for higher education and future careers in sciences, focusing on developing critical thinking skills, laboratory competencies, and an understanding of the scientific processes that influence living organisms.

Overall Expectations

By the end of this course, the student will:


Scientific inveStigAtion SkillS And cAreer explorAtion

  • Demonstrate scientific investigation skills (related to both inquiry and research) in the four areas of skills (initiating and planning, performing and recording, analysing and interpreting, and communicating);
  • Identify and describe careers related to the fields of science under study, and describe contributions of scientists, including Canadians, to those fields.



  • Analyse technological applications of enzymes in some industrial processes, and evaluate technological advances in the field of cellular biology;
  • Investigate the chemical structures, functions, and chemical properties of biological molecules involved in some common cellular processes and biochemical reactions;
  • Demonstrate an understanding of the structures and functions of biological molecules, and the biochemical reactions required to maintain normal cellular function.


metABolic proceSSeS

  • Analyse the role of metabolic processes in the functioning of biotic and abiotic systems, and evaluate the importance of an understanding of these processes and related technologies to personal choices made in everyday life;
  • Investigate the products of metabolic processes such as cellular respiration and photosynthesis;
  • Demonstrate an understanding of the chemical changes and energy conversions that occur in metabolic processes.


moleculAr geneticS

  • Analyse some of the social, ethical, and legal issues associated with genetic research and biotechnology;
  • Investigate, through laboratory activities, the structures of cell components and their roles in processes that occur within the cell;
  • Demonstrate an understanding of concepts related to molecular genetics, and how genetic modification is applied in industry and agriculture.



  • Evaluate the impact on the human body of selected chemical substances and of environmental factors related to human activity;
  • Investigate the feedback mechanisms that maintain homeostasis in living organisms;
  • Demonstrate an understanding of the anatomy and physiology of human body systems, and explain the mechanisms that enable the body to maintain homeostasis.


populAtion dynAmicS

  • Analyse the relationships between population growth, personal consumption, technological development, and our ecological footprint, and assess the effectiveness of some Canadian initiatives intended to assist expanding populations;
  • Investigate the characteristics of population growth, and use models to calculate the growth of populations within an ecosystem;
  • Demonstrate an understanding of concepts related to population growth, and explain the factors that affect the growth of various populations of species.
