IB Biology SL
Introduction
The IB Biology course provides an excellent grounding of knowledge, techniques and
experiences for the committed life scientist hoping to pursue a related degree or career.
It dovetails effectively with a range of other subjects, providing insight into
applications of science, the workings of the scientific community and core global and
ethical issues. These ideas are founded on a detailed theoretical knowledge developed
during the course. The course will provide ample opportunities for students to develop
their potential in the Theory of Knowledge and Extended Essay parts of the IB
Diploma. Emphasis is placed on thinking skills, problem solving and consideration of

some of the key skills in science - analysis, evaluation and synthesis of knowledge.
Biology is a practical subject and its experiences are developed through use of a range
of apparatus and ICT equipment which complements hands-on practical work.
Investigative work forms a spine of the biologist’s studies and its emphasis is rightly
encouraged in the course. This includes the ‘Group 4 Project’ in collaboration with
those studying physics, chemistry and design technology.
Content
Four basic concepts run throughout the course. These are: structure and function,
universality versus diversity, equilibrium within systems and evolution.
The core at Standard Level comprises
the following topics.
1. Cells
2. The chemistry of life
3. Genetics
4. Ecology and evolution
5. Human health and physiology
The options available are two from:
• Evolution,
• Neurobiology and behaviour
• Applied plant and animal science
• Ecology and conservation
• Diet and human nutrition
• Physiology of exercise
• Cells and energy
Assessment
The course is examined through three written papers contributing a total of 76% of the
final grade. The papers cover a range of multiple-choice, structured and extended
response questions, which solve a substantial problem or carry out a piece of analysis
or evaluation. The remaining 24% of the marks come from the investigative skills
developed over the course and during the Group 4 project.
