IB Physics Syllabus (2025): Course Description and Aims

Physics, as one of the natural sciences in the IB Diploma Programme, explores the fundamental nature of the universe - from subatomic particles to cosmic structures. It encourages students to ask deep questions about time, space, energy, and matter, while developing models and theories that explain observed phenomena. Through this process, students gain a richer understanding of the natural world and its underlying principles.

The IB Physics course emphasizes scientific inquiry, both in theoretical contexts and hands-on experimental work. Students develop skills in observation, data analysis, and modeling as they investigate physical systems, interpret results, and evaluate evidence. With strong connections to technology and interdisciplinary learning, the course prepares students to approach unfamiliar problems with creativity and critical thinking.

Throughout the course, students examine the ethical, environmental, and societal implications of physics, gaining an awareness of how science can shape - and be shaped by - human activity. They also learn to collaborate effectively, communicate scientific ideas clearly, and understand the limitations and possibilities of scientific knowledge.

By fostering real-world application, IB Physics empowers students to engage with pressing scientific issues and prepares them for studies in science, engineering, and technology-related fields.
