SBI 4UO COURSE OUTLINE


 
This course provides students with the opportunity for in-depth study of concepts and processes associated with biological
systems. Students will study theory and conduct investigations in the areas of metabolic processes, molecular genetics,
homeostasis, evolution, and population dynamics. Emphasis will be placed on achievement of the detailed knowledge and refined skills needed for further study in various branches of the life sciences and related fields.
Prerequisite: SBI 3U
Text: Biology 12, Nelson
  
Unit 1: Metabolic Processes (17 hours)
Students will describe the structure and function of the macromolecules necessary for the normal metabolic functions of all living things, and the role of enzymes in maintaining normal metabolic functions. Laboratory investigations will be conducted into the transformation of energy in the cell, including photosynthesis and cellular respiration, and into the chemical and physical properties of biological molecules. Ways in which knowledge of the metabolic processes of living systems can contribute to technology development and affect community processes and personal choices in everyday life will be explained.

Unit 2: Molecular Genetics (17 hours)
Students will explain the concepts of gene and gene expression and the roles of DNA, RNA, and chromosomes in cellular metabolism, growth, and division, and demonstrate an awareness of the universality of the genetic code. Laboratory activities and conceptual models will be used to explain processes within the nucleus. Descriptions will be given of some of the theoretical issues surrounding scientific research into genetic continuity; the general impact and philosophical implications of the knowledge gained; and some of the issues raised by related technological applications.  
Unit 3: Homeostasis (17 hours)

 
Students will describe and explain the physiological and biochemical mechanisms involved in the maintenance of homeostasis. Analysis will be made, through experiments and the use of models, of the feedback mechanisms that maintain chemical and physical homeostasis in animal systems. Students will also analyse how environmental factors (physical, chemical, emotional, and microbial) and technological applications affect/contribute to the maintenance of homeostasis, and examine related societal issues.  

Unit 4: Evolution (17 hours)


Students will analyse evolutionary mechanisms, and the processes and products of evolution. Evaluation will be made of the scientific evidence that supports the theory of evolution. Analysis will be made of how the science of evolution can be related to current areas of biological study, and how technological development has extended or modified knowledge in the field of evolution.


Unit 5: Population Dynamics (17 hours)

Students will analyse the components of  population growth, and explain the factors that affect the growth of various populations of species. Investigations will be made followed by analysis, and evaluations of populations, their interrelationships within ecosystems, and the effect on the sustainability of life on this planets. Students will then evaluate the carrying capacity of the Earth, and relate the carrying capacity to the growth of populations, their consumption of natural resources, and advances in technology.



Unit 6: Making Connections (5 hours)

A summative assessment tasks will be conducted, aimed at assessing the goals of this course.
