Curriculum Policy:
Science, The Ontario Curriculum, Grades 11 and 12, 2008 (Revised)

Course Description:
The SBI3U course delves into key biological concepts, including cellular processes, genetics, evolution, and biodiversity. Students engage in laboratory investigations that develop their scientific skills in observation, experimentation, and data analysis. They explore the structure and function of cells, mechanisms of inheritance, and ecological relationships, emphasizing the impact of human activities on ecosystems. By integrating theory with practical applications, students refine their critical thinking and communication skills, preparing them for further studies in the life sciences while fostering an appreciation for the complexity of life and environmental stewardship.

Chapters and Descriptions:

• Cell Biology
  This chapter covers the structure and function of cells, including the differences between prokaryotic and eukaryotic cells. Students explore cellular organelles, their roles in cellular processes, and the importance of cell membranes in maintaining homeostasis.
• Genetics and Heredity
  Students investigate the principles of inheritance, including Mendelian genetics and the role of DNA in heredity. Topics include gene structure, chromosome behavior during meiosis, and patterns of inheritance, along with applications in genetic technologies.
• Evolution
  This chapter examines the theory of evolution, natural selection, and the evidence supporting evolutionary changes in populations. Students analyze evolutionary mechanisms, speciation, and the relationship between biodiversity and evolutionary processes.
• Ecology and Ecosystems
  Students explore the interactions between organisms and their environments, focusing on ecosystem dynamics, energy flow, and nutrient cycling. Topics include population ecology, community interactions, and the impact of human activities on ecosystems.
• Human Impact on the Environment
  This chapter addresses environmental issues related to human activities, including pollution, habitat destruction, and climate change. Students evaluate strategies for sustainability and conservation, emphasizing the role of individuals and communities in protecting biodiversity.
