What is IB Chemistry?
IB Chemistry is a fundamental course that is part of the IB Diploma Program. The primary focus of chemistry is to identify patterns that help explain the behavior of matter at the microscopic level, which then allows us to predict and control its behavior at the macroscopic level. This requires the development of representative models and explanatory theories that rely heavily on creative and rational thinking.
Through the IB Chemistry course, students can actively engage in scientific issues that are relevant to the world today. Exploring chemistry will help you develop a deeper understanding, acquire new skills and techniques that can be applied to other areas of study and beyond.
An essential part of the IB Chemistry course is the opportunity for students to engage in scientific inquiry both in the classroom and laboratory settings. This allows students to discover and understand scientific concepts through experimentation, which is crucial to the learning experience. By engaging in scientific inquiry, students can further develop their critical thinking, problem-solving, and analytical skills.
IB Chemistry SL vs HL
The IB Chemistry course is offered at two levels within the International Baccalaureate (IB) Diploma Programme: Standard Level (SL) and Higher Level (HL). Both courses cover the same core topics, such as atomic structure, bonding, and stoichiometry. However, they differ in terms of depth, complexity, and teaching hours.
Standard Level (SL)
The IB Chemistry SL course is designed to provide students with a solid foundation in chemistry and to develop critical thinking, problem-solving, and analytical skills. This course is suitable for students who have a general interest in chemistry or those who plan to pursue other fields in higher education. Successful completion of the IB Chemistry SL course may lead to university credits, advanced placement, or exemption from introductory courses in higher education.
IB Chemistry SL covers core topics in chemistry, such as atomic structure, bonding, stoichiometry, and thermodynamics. In addition, the course covers some optional topics, including modern analytical chemistry and medicinal chemistry.
Higher Level (HL)
IB Chemistry HL covers all the topics covered in IB Chemistry SL, but with additional and more in-depth topics such as organic chemistry, biochemistry, and environmental chemistry. The HL course requires students to have a deeper understanding of the core topics and to be able to apply their knowledge to more complex situations.
The IB Chemistry HL course is designed for students who plan to pursue the field further in higher education. The course provides a more rigorous and in-depth study of chemistry, preparing students for university-level coursework in chemistry and related fields. Successful completion of the IB Chemistry HL course may lead to university credits, advanced placement, or exemption from introductory courses in higher education.
IB Chemistry SL vs HL
|Aspect||Standard Level (SL)||Higher Level (HL)|
|Purpose||For students with a general interest in chemistry or those who wish to study the subject as part of a broader scientific education.||For students with a strong interest in chemistry or those intending to pursue a career or further studies in the field.|
|Core Topics||Covers a set of core topics that provide a solid foundation in chemistry.||Shares the same core topics as SL but delves deeper into the concepts.|
|Assessment Structure||Less demanding assessments, focusing on essential concepts and principles.||More rigorous assessment structure, challenging students to develop a deeper understanding of the subject and refine their problem-solving abilities.|
The New IB Chemistry Program Starting in 2023
The IB Chemistry program is undergoing significant changes in 2023. To read the complete update, check out the IB website. Otherwise, we’ve summarized the key changes, which include:
- New course structure: The new curriculum is centered around two primary concepts: structure and reactivity. These concepts are further divided into various topics and subtopics, all linked by the fundamental principle that structure determines reactivity, which in turn transforms structure.
- Conceptual learning: The course will reduce content and emphasize concepts, enabling students to connect factual, procedural, and meta-cognitive knowledge and apply their understanding in new contexts.
- Skill development: The course will emphasize skill development, including inquiry skills and techniques, framed by the approaches to learning (ATL) skills.
- Nature of science: This overarching theme will explore conceptual understandings related to the purpose, features, and impact of scientific knowledge, fostering scientific literacy and supporting student learning.
- Practical work: Teachers will develop their practical schemes of work, allowing students to gain deeper subject understanding and develop a wide range of practical and investigative skills.
- Collaborative sciences project: This interdisciplinary project will address real-world problems and allow students to work with those from other DP sciences courses, developing teamwork, negotiation, and leadership skills.
- Changes to the assessment model:
- External assessment: Students will only sit two external exams, with Paper 1A covering multiple-choice questions, Paper 1B focusing on data analysis questions, and Paper 2 including short-response and extended-response questions. Option topics will be removed, with some content incorporated into the core course.
- Internal assessment: The 'scientific investigation' will allow students to collaborate in small groups, each submitting an individual report (max. 3,000 words). The revised criteria will emphasize higher-order thinking skills, with 50% of marks allocated for Conclusion and Evaluation.

In addition to the theoretical knowledge gained in IB Chemistry, students must participate in an experimental program, which complements their learning and reinforces key concepts. This hands-on approach includes practical work, collaborative science projects, and scientific investigations.
Practical work forms an integral part of the IB Chemistry curriculum, with students dedicating 40 hours for SL and 60 hours for HL to various lab activities. Teachers are encouraged to develop their practical schemes, incorporating technology and exposing students to diverse tasks, from closed to open inquiry and hands-on experimentation to simulations and modelling.
Furthermore, students will engage in a 10-hour collaborative sciences project, an interdisciplinary endeavour that addresses real-world problems across various science subjects. This project enables students to integrate their knowledge, develop solution-focused strategies, and understand the complexity of solving real-world issues. Students will also work on strengthening their Approaches to Learning (ATL) skills, including team building, negotiation, and leadership.
Finally, students must complete a 10-hour scientific investigation focusing on a research question or hypothesis relevant to their studies. This independent project allows students to deepen their understanding of the scientific process and develop critical thinking, problem-solving, and analytical skills.
The experimental program enhances students' comprehension of theoretical concepts. It equips them with practical skills and experiences that foster a well-rounded understanding of the subject and its applications in the real world.
