Ultimate Guide to the IB Physics Extended Essay

Are you preparing to tackle your IB Physics Extended Essay and looking for impactful topics, insightful writing tips, and expert guidance? You've landed in the right place! This post will provide you with essential information and strategies to help you craft a compelling IB Physics EE.

As an IB Physics student, the task of writing a 4000-word extended essay (EE) is an exciting yet formidable challenge. Selecting a topic that is engaging and manageable is crucial to ensuring your EE stands out. In this blog post, I will walk you through a clear, step-by-step method to develop the perfect IB Physics EE research question.

Guide to Develop Your IB Physics EE Ultimate Research Question:

  1. Choose a Broad Topic: Begin with a wide-ranging area of interest, such as the physics of sound.

  2. Generate a Starter Question: Use this question to spark ideas for narrowing your focus.

  3. Formulate Your Research Question: Concentrate on one independent variable and one dependent variable.

  4. Sketch Out a Research Plan: Outline the methods you'll use to explore your research question.

  5. Envision a Potential Outcome: Predict the possible results or conclusions of your study.

Once you’ve completed these steps, you will have a comprehensive plan ready to discuss with your Physics EE supervisor. They will offer further guidance on conducting your practical experiments in your school’s lab facilities.

Choosing Your IB Physics EE Topics

The first step in your EE journey is selecting a topic that not only interests you but also allows you to apply the principles of physics. An excellent IB Physics EE topic should challenge you to think critically and apply scientific theories to real-world phenomena. For instance, exploring the relationship between the viscosity of a fluid and its effect on terminal velocity presents a perfect blend of theory and practical investigation.

How to Write an IB Physics EE

Writing an IB Physics Extended Essay involves several key components. Your essay should start with a clear title that encapsulates your research. Following this, your research question should be precise and presented early in the introduction. It is vital to frame this question in a way that invites scientific investigation—ask "What is the relationship between X and Y?" rather than simply stating a hypothesis.

Methods of Approach

You have the choice between a theoretical essay or an experimental study. If you decide on an experimental approach, consider whether you will gather primary data or rely on secondary sources. When using secondary data for your IB Physics EE, ensure you critically assess its accuracy and relevance to your research question. This approach will not only enhance the validity of your study but also demonstrate your analytical skills.

Importance of Theory in IB Physics EE

No matter the nature of your experimental work, it should always be grounded in robust theoretical research. This involves detailed exploration of the relevant physical laws and principles that govern the phenomena you are studying. For example, if your topic concerns the acoustics of an exhaust pipe, you should delve into the physics of sound waves and how they interact with different environments.

IB Physics Extended Essay Tips

Here are some quick tips to enhance your IB Physics EE:

- Keep your research question focused and manageable.

- Ensure your experimental methods are clear and replicable.

- Engage with theoretical concepts to deepen your analysis.

- Avoid overly complex apparatus that might obscure the physics concepts you're exploring.

Ultimately, this post aims to provide a launching pad, illustrating the breadth of potential topics within physics that are ripe for a detailed extended essay. With dedicated research and thoughtful analysis, you can craft a compelling, insightful essay that showcases your enthusiasm and understanding of physics.

Ultimate Sample Topic list to the Physics EE:

Topic 1: The Effect of Temperature on the Electrical Resistance of Metals


Begin with a detailed study of electrical resistivity, focusing on how and why different metals respond to changes in temperature. Review academic literature and scientific texts that discuss the principles of electrical conductivity and the impact of thermal energy on atomic structures in metals.


Design an experiment to measure the resistance of several metals (like copper, aluminum, and iron) at various temperatures. This will involve heating metal wires in a controlled environment and using a multimeter to measure changes in resistance.

Data Analysis

Analyze the collected data to determine how the resistance of each metal changes with temperature. Use graphical representations to highlight the relationship and apply statistical tools to validate the findings.

Results and Conclusion

Conclude by summarizing the relationship between temperature and resistance for the metals tested. Discuss the implications of these findings in real-world applications, such as in electrical engineering and materials science. Highlight the limitations of the experiments and suggest areas for further research.

Topic 2: Investigating the Refractive Index of Liquids with Temperature


Explore the theory behind light refraction and how the refractive index of a substance changes with temperature. Gather resources on the molecular dynamics of liquids and how thermal expansion affects optical properties.


Set up an experiment to measure the refractive index of various liquids (such as water, glycerin, and vegetable oil) at different temperatures using a refractometer or a similar device.

Data Analysis

Process the experimental data to examine the correlation between temperature and the refractive index. Utilize models to predict changes and discuss the accuracy of these models compared to the experimental data.

Results and Conclusion

Discuss how the refractive index variation with temperature can affect optical applications, like lens design and optical fiber technology. Consider the experimental design's effectiveness and propose modifications for future studies.

Topic 3: The Doppler Effect and Its Applications


Study the Doppler Effect thoroughly, focusing on its theoretical basis and its applications in various fields such as astronomy, radar, and medical imaging. Review historical development and key experiments that have shaped understanding of the phenomenon.


Conduct experiments to observe the Doppler Effect using sound waves. This could involve recording the frequency of a sound from a moving source at various speeds and distances.

Data Analysis

Analyze the frequency changes and compare them with theoretical predictions. Use software tools to simulate the effect under different conditions and compare these simulations with your experimental data.

Results and Conclusion

Evaluate how well the experimental and simulated results align with theoretical expectations. Discuss the implications of the Doppler Effect in modern technology and potential areas for future research.

Topic 4: Measuring the Gravitational Constant Using Simple Pendulum


Review the historical context of gravitational studies and Newton’s law of universal gravitation. Study different methods that have been used to measure the gravitational constant, focusing on the role of pendulums.


Design a series of experiments to measure the gravitational constant using a simple pendulum setup. This involves varying lengths of the pendulum and measuring oscillation periods accurately.

Data Analysis

Apply mathematical formulas to calculate the gravitational constant from the experimental data. Compare these findings with accepted values and analyze discrepancies.

Results and Conclusion

Summarize the effectiveness of using a simple pendulum to measure gravitational forces. Discuss potential experimental errors or environmental factors that could affect accuracy and suggest improvements for further experiments.

Topic 5: Photovoltaic Efficiency in Different Light Conditions


Investigate the principles of photovoltaic cells and how their efficiency is influenced by different wavelengths and intensities of light. Explore both theoretical perspectives and practical implementations in solar technology.


Set up solar cells under varied lighting conditions to measure output voltage and current. Use different types of light sources, such as LED, halogen, and natural sunlight.

Data Analysis

Analyze how light intensity and type affect the efficiency of the solar cells. Use the data to model performance in real-world solar applications.
