OGC Extended Essay: Chemistry

Chemistry: Overview

An extended essay (EE) in biology provides students with an opportunity to apply a range of skills while
researching a topic of personal interest in the field of biology.


Biology is the science that deals with living organisms and life processes. A biology EE should incorporate
biological theory and emphasize the essential nature of this subject.

 

Requirements for a Chemistry EE

The Subject-Specific Guidance page for your chosen subject is THE KEY to ensuring your paper meets the requirements. Print, highlight, and annotate this page and pin it above your desk!

The Command Terms are the key terms and phrases used in examination questions. Using these in your essay will indicate a strong background in your subject

The Subject Reports give an overview of what EXAMINERS have said about makes a successful paper in the subject. It's smart to read these over to know what the examiners are looking for.

Sample Research Questions

Review the questions below

  • Which ones will be most successful?

Past Papers: Why Read Them?

  • See common structures, methodologies, use of command terms and other subject-specific vocabulary
  • Notice the difference between successful papers AND papers that were less successful
  • Read the examiner comments on scored papers and their reflections to note what worked and what didn't
