Physics IA word count and page limit [2025 updated]
Is your Physics IA deadline coming up and you’re not sure about the formal requirements and recommended structure? This guide is here to help you! Read further to find out more about writing this IA and increase the chance of acing your grade.
Physics IA is a scientific investigation that should be a maximum 3,000 words. There is no page limit. The report requires a purposeful research question and the scientific rationale for it. The basic structure includes an introduction, main body, and conclusion, which can be further subdivided.
Introduction
Begin your essay by introducing the research question and contextualizing the study. In this section of up to 500 words state and explain your hypothesis drawing from the acquired theoretical knowledge. Provide definitions of the physical phenomena, laws, etc, and present the physical properties of the materials, which are subject to your study. Remember to use specific physics terminology taught in the IB course. In the introduction demonstrate your personal engagement by for instance relating to your areas of interest or showcasing proactive involvement in conducting the research.

Main body
The main body of around 2,000 words consists of the investigation and analysis. The first subsection should be the methodology. Describe what kind and how many of the apparatus and materials are needed to conduct the experiment. Detailed, step-by-step instructions for the procedure must be included. It is also crucial to consider measurement uncertainties. Next, identify the controlled and uncontrolled variables and state how they can impact the investigation. In the further section of the main body, you should present the obtained results and process them to find out the answer to the research question. In this part you need to incorporate formulas and calculations with clearly noted units. Look for tendencies throughout the data. In case you find anomalies, analyse potential factors that could have led to the deviations from the trend. The report should include sufficient relevant quantitative and qualitative raw data that could support a valid conclusion. For good presentation and communication use graphs, tables, and images.

Conclusion
In the final section, under 500 words, clearly state the answer to the research question. Asses your investigation and the obtained results with regard to the focus of the research. In the evaluation, highlight your methodology's advantages and disadvantages and suggest how the investigation could have been improved. Consider the ways of extending your research.
