BIOLOGY

Grade 12 Biology

Course Type: University Preparation

Credit hours: 110

Credit: 1.0

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.

Big Ideas

Biochemistry

• Technological applications that affect biological processes and cellular functions are used in the food, pharmaceutical, and medical industries.

• Biological molecules and their chemical properties affect cellular processes and biochemical reactions.

• Biochemical compounds play important structural and functional roles in cells of all living organisms.

Metabolic Processes

• All metabolic processes involve chemical changes and energy conversions.

• An understanding of metabolic processes enables people to make informed choice with respect to a range of personal, societal, and environmental issues.

Molecular Genetics

• DNA contains all the genetic information for any living organism.

• Proteins control a wide variety of cellular processes.

• Genetic research and biotechnology have social, legal, and ethical implications.

Homeostasis

• Organisms have strict limits on the internal conditions that they can tolerate. • Systems that maintain homeostasis rely on feedback mechanisms.

• Environmental factors can affect homeostasis.

Population Dynamics

• Population growth follows predictable patterns.

• The increased consumption of resources and production of waste associated with

  population growth result in specific stresses that affect Earth’s sustainability.

• Technological developments can contribute to or help offset the ecological footprint

  associated with population growth and the consumption of natural resources.

Assessment & Evaluation for Student Achievement

According to Growing Success (2010), the main goal of assessment and evaluation is to enhance student learning. By gathering assessment data, teachers can identify students’ strengths and areas for improvement in relation to curriculum expectations. This information helps educators adjust their teaching methods and curriculum to better meet students’ needs while also evaluating the effectiveness of programs and classroom strategies. Additionally, teachers provide students with descriptive feedback to support their progress and encourage continuous improvement.

​

The final grade will be determined as follows:

• 70% of the grade will be based on ongoing assessments conducted throughout the course. This portion reflects the student’s most consistent level of achievement, with special consideration given to more recent evidence of learning.

• 30% of the grade will be based on a final evaluation completed at or near the end of the course. This assessment may include an exam, a performance, or another evaluation method appropriate to the course content. The final evaluation provides students with an opportunity to demonstrate their overall understanding of the course expectations.
