Biology

B I O L O G Y

The science of biology continues on an inexorable rise which can be traced back to the elucidation of the structure of DNA in 1953. With a rapid pace of advance in such areas as the diagnosis and treatment of cancer, ever higher resolution mapping of the human brain, the precision of modern DNA editing not to mention the impact of Covid-19, biologists have never been in greater demand.

The aims of the IB Biology course are:

• To develop conceptual understanding that allows connections to be made between different areas of the subject, and to other IB Diploma sciences subjects • To acquire and apply a body of knowledge, methods, tools and techniques that characterise science • To develop the ability to analyse, evaluate and synthesise scientific information and claims • To develop the ability to approach unfamiliar situations with creativity and resilience • To design and model solutions to local and global problems in a scientific context • To develop an appreciation of the possibilities and limitations of science • To develop technology skills in a scientific context • To develop the ability to communicate and collaborate effectively • To develop awareness of the ethical, environmental, economic, cultural and social impact of science. The syllabus is divided into four key themes, each made up of two concepts: Unity and diversity; Form and function; Interaction and interdependence; Continuity and change. These themes are explored at the various levels of biological organisation: Molecules; Cells; Organisms; Ecosystems. Each theme and level of organisation provides a conceptual lens through which the content can be explored. At the very end of the summer holiday prior to the start of Upper Sixth, the pupils will take part in a residential field trip to South Devon. Whilst not mandatory, the trip is highly valuable and typically, all pupils attend. The trip contributes to the obligatory IB practical hours, allows pupils to experience first-hand many of the ecological techniques in the syllabus and most importantly allows pupils to collect the necessary data for a successful Internal Assessment (see below).
