IB Chemistry Syllabus & Topics
The following content outlines the syllabus for IB Chemistry, a subject within the International Baccalaureate (IB) Diploma Programme.
This course is designed for students who are curious about the nature of matter and chemical processes, with a strong emphasis on critical thinking and scientific inquiry. It promotes concept-based learning, encouraging students to make connections between theoretical knowledge and real-world applications.
The IB Chemistry syllabus builds on the spirit of inquiry at the heart of the course. It’s designed to guide students through the key concepts, skills, and methods that define modern chemistry, encouraging them to see how scientific understanding develops and connects across different areas.
Throughout the syllabus, students move from exploring the foundations of atomic structure and bonding to tackling the complexities of thermodynamics, kinetics, and organic chemistry. Along the way, they investigate how these ideas apply to real-world contexts - from environmental sustainability to medical and industrial innovation.
Ultimately, the IB Chemistry syllabus is more than a list of topics - it’s a framework for thinking scientifically, connecting ideas, and discovering how chemistry shapes our world.
