What Is the IB Group 4 Project?
The Group 4 Project is a mandatory interdisciplinary science requirement in the IB Diploma Programme. It brings together students from at least two different Group 4 subjects—such as Biology, Chemistry, Physics, or ESS—to collaborate on a shared scientific theme.
The project typically involves around 10 hours of combined planning, experimentation, analysis, and presentation. Its purpose is not assessment, but skill development within the framework of the International Baccalaureate.
Benefits of the Group 4 Project
Strengthens Collaboration and Communication
Working across disciplines requires clear communication, task delegation, and collective decision-making. These skills mirror real scientific and academic environments and are highly transferable to university study and STEM careers.
RevisionDojo highlights that students often gain confidence in presenting ideas and coordinating group work through the Group 4 Project.
Encourages Interdisciplinary Thinking
Unlike regular science classes, the Group 4 Project pushes students to combine concepts from different scientific fields to explore real-world problems. This broader perspective helps students understand how scientific disciplines overlap rather than exist in isolation.
Builds Research and Practical Skills
The project closely resembles Internal Assessment-style work:
- Designing investigations
- Collecting and interpreting data
- Evaluating methods and outcomes
Students often find the Group 4 Project useful preparation for later laboratory work and IAs.
