Biology International Baccalaureate at Sir Henry Floyd Grammar School

Course description

Biology is a Group 4 subject. The IB course takes 2 years and during this demanding but challenging course, students will become aware of how scientists work and communicate with each other. The IB syllabus will develop knowledge and understanding of key biological concepts through the study of a range of core topics from cells to human physiology. A variety of teaching and learning styles will be used along with laboratory practicals to bring the full aims of the IB course including internationalism and TOK to life.

Course content

The syllabus is delivered in a series of topics. All students study the core topics at Standard Level (Topics 1-6) while only the Higher Level students will study the additional topics (Topics 7-11). Students will also study one Option topic.

1. Cell biology
2. Molecular biology
3. Genetics
4. Ecology
5. Evolution and biodiversity
6. Human physiology
7. Nucleic acids
8. Cell respiration and photosynthesis
9. Plant biology
10. Genetics and evolution
11. Animal physiology

Group 4 Project: This is an interdisciplinary project designed to enable students to work collaboratively as scientists on creative projects and gain invaluable hands-on appreciation of scientific work.

Internationalism: Through the study of topics such as AIDS, stem cell research, sustainability of ecosystems, students will develop a global awareness of scientific issues that affect all of us no matter where we live in the world.

Entry requirements

A student wishing to study biology should preferably have a grade A or A* in GCSE biology or core and additional science to be confident of success but certainly no less than grade B. A GCSE grade C or better in chemistry is necessary if you have studied biology as a separate science.


Practical work is assessed throughout the course. Higher Level students spend 60 hours of the course on practical work, and Standard Level students spend 30 hours. All practical work must be written up in a lab notebook and is internally assessed, contributing 20 per cent of the final grade.
