GROUP 4 - BIOLOGY

Image_19

Biology is an experimental science in which the scientific method of investigation forms an integral part of the study of living organisms. Within the course, living things are studied from the molecular level through to the macro interactions which occur in the biosphere. By the end of this course, students should have developed an appreciation of the interactions between these levels and of the organisms functioning as entities in the biosphere.

Standard Level

The material covered in the core includes: Cell Biology, Molecular Biology, Genetics, Ecology, Evolution and Biodiveristy and Human Physiology. There is an extensive programme of practical investigations.

Standard Level students are required to study one option chosen from: Human Physiology, Neurobiology and Behaviour, Biotechnology and Bioinformatics, Ecology and Conservation. The duration of the option is 15 hours.

ASSESSMENT (SL)
Internal Assessment
The internal investigation is a report on a single investigation which involves approximately 10 hours and should be in the region of between 6-12 pages in length. (20%)
External Examinations
Paper 1: 30 multiple choice questions. (0.75 hour, 20%)
Paper 2: Data-based question, several short answer questions and an extended response. (1.25 hours, 40%)
Paper 3: Several short answer questions based on experimental data and short answer and extended response questions from the option studied (1 hour, 20%).

Higher Level

In addition to the Standard Level core work, Higher Level material builds on or includes the following: Nucleic Acids, Metabolism, Cell Respiration, Photosynthesis, Plant Biology, Genetics and Evolution, Animal Physiology.

Higher Level students are required to study one option chosen from Neurobiology and Behaviour, Ecology and Conservation, Human Physiology, Biotechnology and Bioinformatics. The duration of the option is 25 hours.
