OGC Extended Essay: Biology

Biology: 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 Biology EE

Ensure your paper meets the requirements: Print, highlight, and annotate this page and pin it above your desk!

Use Command Terms in your essay to indicate a strong background in your subject

Read what EXAMINERS have said to know what the examiners are looking for.

Read about a BROAD topic to gradually narrow to a FOCUSED topic.

Once you have a focused topic, read more to generate a Research Question that you KNOW you can answer in a thesis statement.

Sample Research Questions

Review the questions below

  • Which ones will be most successful?
  • What ideas do the questions spark for you?

 

Biology Questions, scoring A or B

  • How do different concentrations of aspartame etc etc affect differently on the human gut microbiota etc etc? 

  • How does the effectiveness of cotrimoxazole on Escherichia coli differ from different drug dispensaries in the Pakkret region? 

  • How do different concentrations of ​Tamarindus indica​ pulp solution extracted by using 50% aqueous ethanol and 70 ̊C deionized water affect differently on ​Escherichia coli​ as measured​ by the zone of inhibition? 

  • How do different doses of the antioxidants Vitamin C and Vitamin E affect the human immune system in the short-term? 

  • To what extent do adding different concentrations of Plant Growth Promoting Rhizobacteria (PGPR), affect the growth of seeds of non-legumes of agricultural plant, Jasmine rice (Oryza Stiva L.), measured by the length of roots and shoots? 

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
