IBDP Biology is an exciting course that explores the science of life. From the tiniest cells to the most complex ecosystems, you’ll dive into how living things function, grow, and interact with the world around them.
Whether you’re aiming for a career in medicine, environmental science, or just curious about how the human body works, this course will help you build a strong foundation in biology — while also developing critical thinking, data analysis, and lab skills.
The course enables students, through the overarching theme of the NOS, to:
- develop conceptual understanding that allows connections to be made between different areas of the subject, and to other DP sciences subjects
- acquire and apply a body of knowledge, methods, tools and techniques that characterize science
- develop the ability to analyse, evaluate and synthesize scientific information and claims
- develop the ability to approach unfamiliar situations with creativity and resilience
- design and model solutions to local and global problems in a scientific context
- develop an appreciation of the possibilities and limitations of science
- develop technology skills in a scientific context
- develop the ability to communicate and collaborate effectively
- develop awareness of the ethical, environmental, economic, cultural and social impact of science.
