Many students have asked me, “What should I choose as my Physics IB Internal Assessment topic?” I’ve written many IB papers, so I know what they ask. Picking the right option is very important because it builds a substantial project. This Internal Assessment is a perfect chance to show how well you understand physics ideas by doing your research. So, if you need some inspiration, check out the Physics IB IA topic ideas I provide below.
What Is a Physics Internal Assessment?
As an experienced IB writer, I can attest that the Internal Assessment is one of the most fascinating and intricate components of the IB Physics course. Consider it your chance to become a physicist by planning and researching a topic that piques your interest. The Internal Assessment emphasizes your ability to apply what you’ve learned in a real-world setting instead of standard tests that assess your knowledge.
A mandatory component of the IB Diploma Program, Physics IA significantly impacts your final result. It helps you to develop several crucial abilities, such as:
- Designing and conducting an experiment.
- Methodically evaluating facts and clearly presenting them.
- Using the principles of physics to connect your results.
In my perspective, the IB Internal Assessment is about demonstrating your innovation and curiosity, not simply about fulfilling the standards. It’s a unique research project since you can choose your topic. As long as it is within the requirements of the curriculum, you may research everything from electromagnetic wave characteristics to pendulum mechanics.
I always stress that students should stay in line with the IB standards. Your Internal Assessment shows your grasp of physics ideas and critical thinking abilities, not just your ability to experiment. Approaching it from the correct perspective can help you find one of the most fulfilling aspects of your IB program.

Final Checklist for Choosing Your Physics IA Topic
When choosing a topic that meets all these requirements, you position yourself for a more seamless IA writing process and a better result. Remember that the Internal Assessment is your opportunity to demonstrate your analytical abilities and curiosity, so make the most of it!
Does the Topic Meet IB Requirements?
Above all, make sure your topic fits the IB Physics IA requirements. In my opinion, the best topic consists of quantifiable factors, a well-stated hypothesis, and workable strategies that you can confidently implement.
Avoid topics that are too general or ambiguous since IB assessors prefer structure and clarity. For example, you may query, “How does the thickness of insulation affect the heat transfer rate?” rather than, “How does heat transfer work?” This level of detail will help you remain on task and fulfill the requirements of the IB rubric.
Can You Perform This Exmepiment?
A great topic has to be useful in addition to being fascinating. Consider whether you have the necessary tools and supplies to conduct your research. Also, think about the time required for data gathering and processing as well. I’ve found that students who realistically prepare their experiments are far less likely to suffer stress at the last minute.
For instance, most students may be able to investigate how various angles affect projectile speed with only basic supplies like a ball, a ramp, and a protractor. However, reproducing a large-scale particle impact experiment without sophisticated lab access is impossible.
