The IB Physics Internal Assessment (IA) is your opportunity to design and conduct an independent investigation into a physics phenomenon. This comprehensive guide will help you understand the word count requirements, structure your report effectively, and create a compelling experimental design.
Your Physics IA should be a thorough investigation spanning up to 3,000 words. The key to success lies in balancing theoretical understanding with practical experimental skills, while maintaining clear and concise scientific communication.
The Physics IA follows a scientific report format with distinct sections, each serving a specific purpose in demonstrating your understanding and experimental skills.
Begin with a clear, focused research question that is neither too broad nor too narrow. Your background should demonstrate understanding of the physics principles involved and justify why your investigation is worthwhile. Include relevant physics theory and equations that will be used in your analysis.
Detail your experimental design with sufficient clarity that another student could replicate your experiment. Include:
Present your raw data clearly in tables with appropriate units and uncertainties. Processed data should include calculations, graphs, and statistical analysis. Address any anomalies or unexpected results with scientific reasoning. This section should demonstrate your ability to manipulate and interpret experimental data.
Critically evaluate your investigation's strengths and limitations. Discuss systematic and random errors, their sources, and impact on results. Conclude with a clear answer to your research question and suggest realistic improvements for future investigations.
Include properly formatted citations and any additional supporting material that doesn't fit in the main report.
Choose a topic that genuinely interests you and allows for quantitative analysis. Avoid overly complex setups that might compromise data quality. Consider phenomena from everyday life that can be investigated with accessible equipment.
Ensure your experiment produces sufficient data points for meaningful analysis. Plan for multiple trials to assess reliability and calculate uncertainties properly.
CiteCount is essential for managing your word count effectively. Our tool excludes citations, equations, and data tables from your count, helping you focus on the analytical content that truly matters for assessment.
Regular word count checks help ensure balanced sections and prevent exceeding the limit while maintaining scientific rigor.
Remember to exclude the following from your word count:
Utilize CiteCount for precise word counting that automatically excludes citations and references, ensuring your focus remains on quality scientific analysis.
Best of luck with your Physics IA!
