An extended essay (EE) in chemistry provides students with an opportunity to investigate a specific aspect of a material of our environment. The essay must be characterized by a particular chemical emphasis within a more general set of research criteria. Chemistry is the science that deals with the composition, characterization and transformation of substances. A chemistry EE should incorporate chemical principles and theory, and emphasize the study of matter and of the changes it undergoes. The outcome of the research should be a coherent and structured piece of writing that effectively addresses a particular research question and arrives at a particular, and preferably personal, conclusion or response to the research question.
An extended essay (EE) in physics should answer a research question in physics through focused, evidence-based argumentation. The evidence may be drawn from the student’s personal experimentation and/or book- and internet-based research. Whichever method of research is adopted, the student must use the principles of physics. The essay must go beyond simply informing the reader and involve the elements of personal and original thinking.
It should be written for an international peer audience, familiar with the Diploma Programme physics course. The essay can therefore refer to any physics from the course without proof or explanation, eg Newton’s laws. However, material from outside the physics course should be fully explained and referenced where necessary. Students should explain it freshly as it applies to their research question, thereby convincing the reader that they have a genuine grasp of the physics involved. Students should also explain any culture-specific matters they refer to in the essay in relation to physics, eg cricket or baseball.
An extended essay (EE) in sports, exercise and health science (SEHS) provides students with an opportunity to apply the wide range of skills in the field of sports, exercise and health science to research into a topic of personal interest. SEHS covers a wide range of topics from human physiology to principles of biomechanics and the nature of skill acquisition. It is an applied science course so its EE investigates a sporting or health-related issue using the principles of science.
