This comprehensive guide offers an in-depth overview of the IB Physics course, addressing its content, structure, and assessment criteria. By discussing the topics included, comparing Standard Level (SL) and Higher Level (HL), explaining the Internal Assessment process, and outlining the external examination format, we aim to provide valuable insights for students, educators, and parents. The guide also includes practical tips and resources to help you navigate this challenging and rewarding course.
IB Physics Overview
IB Physics is a crucial course in the IB Diploma Program that aims to deepen students' understanding of the natural world by exploring concepts, methods, and tools in physics. This course emphasizes scientific inquiry in the classroom and the laboratory and fosters connections with other DP science subjects.
Key goals include developing conceptual understanding, analytical skills, creativity, resilience, problem-solving, and technology skills in a scientific context. Students will also learn to communicate effectively, collaborate, and become aware of the ethical, environmental, economic, cultural, and social impacts of science. Through this course, students will be better equipped to engage with scientific issues and apply their learnings across various fields.
IB Physics SL vs HL
The IB Physics course is offered at two levels within the International Baccalaureate (IB) Diploma Programme: Standard Level (SL) and Higher Level (HL). Both levels are designed to foster students' understanding of the physical world and develop their analytical and problem-solving skills. However, they differ in terms of depth, complexity, and teaching hours.
Standard Level (SL)
The SL course is designed for students with a general interest in physics or those who wish to study the subject as part of a broader scientific education. It covers a set of core topics that provide a solid foundation in physics and requires fewer teaching hours compared to the HL course. The assessments at this level are less demanding, focusing on essential concepts and principles.
Higher Level (HL)
The HL course is tailored for students with a strong interest in physics or those intending to pursue a career or further studies in the field. In addition to the core topics shared with the SL course, the HL course delves into additional higher level (AHL) topics, exploring more complex concepts and theories. The HL course demands more teaching hours and features a more rigorous assessment structure, challenging students to develop a deeper understanding of the subject and refine their problem-solving abilities.

| Core Topics | Covers a set of core topics that provide a solid foundation in physics. | Shares the same core topics as SL but delves deeper into the concepts. |
| Additional Topics (AHL) | None | Includes more complex concepts and theories in additional higher level (AHL) topics. |
| Teaching Hours | 150 | 240 |
| 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 Physics Program Starting in 2023
The IB Physics 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 curriculum will now be grouped into five broad organizing themes, each with several topics, focusing on the interconnectedness of concepts, contexts, and content.
- 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.

Practical work forms an integral part of the IB Physics curriculum, with students dedicating 20 hours for SL and 40 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.
