These subject guidelines should be read in conjunction with the “Introduction”, “Outline” and “Details—all essays” sections of this guide.
Overview

An extended essay in physics provides students with an opportunity to apply a range of skills while researching a topic of personal interest in the field of physics. A physics extended essay is characterized by a particular emphasis on physics within a more general set of scientific criteria. An extended essay in physics must take the form of a research paper involving a hypothesis or a model, or a critical analysis, that demonstrates argumentation, comparison, or the extraction of relevant information or data.

The outcome of the research should be a coherent and structured piece of writing that effectively addresses a particular issue or research question and arrives at a particular, and preferably personal, conclusion.
Choice of topic

It is important that the extended essay has a clear emphasis on physics and is not more closely related to another subject. A physics extended essay should, therefore, have a basis in physical theory and emphasize the essential nature of the subject. An extended essay in an interdisciplinary area such as materials science will, if registered as a physics extended essay, be judged on its physics content, not its chemical content.

The purpose of the essay is not principally to inform the reader about a specific topic, nor should it be a summary of the latest discoveries in physics. The student must be personally involved with the subject matter and not simply an informant. The topic should represent a challenge for the student.

Some topics may be unsuitable for investigation because of safety issues. For example, experiments involving dangerous or carcinogenic substances, radioactive materials, lasers, microwaves, UV light, noise or heavy equipment should be avoided unless adequate safety apparatus and qualified supervision are available. Typical experiments done in class, not suitable in themselves as a basis for an extended essay, can be a source of good topics.

Students should choose a well-focused, well-defined and realistic topic that allows for an in-depth treatment. Broad or complex survey topics, for example, investigations into black holes, gravity, time machines, the Higgs particle or the fate of the universe, will not permit the student to discuss conflicting ideas and theories, nor to produce an in-depth personal analysis within the word limit. Also, by definition, some topics are not suitable for an extended essay in physics, which is an experimental science with a specific approach and techniques.

Students should also be careful to avoid research topics that go beyond the boundaries of conventional science, for example, areas that are more related to metaphysics or pseudo-science. Examples of this could include the unknown forces of pyramids, physics and God’s existence, and extrasensory perception.

The following examples of titles for physics extended essays are intended as guidance only. The pairings illustrate that focused topics (indicated by the first title) should be encouraged rather than broad topics (indicated by the second title).

“Orbital determination of a minor planet” is better than “Gravitation”.

“The variation in resistance of a wire subjected to different strains” is better than “Measuring the resistivity of different materials”.

“The use of interference fringes to measure small displacements” is better than “Making interference patterns”.

“The range variation of water flowing out of a hole in a container” is better than “An application of Bernoulli’s principle”.

“The impact of the resistivity of the metal of a pipe and the pipe’s wall thickness on the terminal velocity of a cylindrical magnet falling down the metallic pipe” is better than “Eddy currents”.

Moreover, it may help if the student further defines the topic chosen for study in the form of a research question, followed by a statement of intent that indicates which broad process is going to be used in answering the question. In this way, the approach to the topic chosen may be even further clarified. Some examples of this could be as follows.
