Writing the Essay
An essay in the sciences requires is more than just generating and presenting data. Analysis of the data is also essential. The main body of the essay should consist of an argument or evaluation based on the data or information presented . You can gather your own data through a variety of methods, or rely on secondary data. You should use graphs, tables, or diagrams to point out the significance of your findings.
You should ensure that the main body of the essay is well structured and has an obvious logical progression. You can use numbered and headed paragraphs to impose a clear structure. Your evaluation should show that you understand the the data they have collected and its significance to the world.
In your analysis, you should also describe and explain the limitations imposed on the research by factors such as
the suitability and reliability of the sources accessed
accuracy and precision of measuring equipment
sample size
validity and reliability of statistics
Students should also consider biological limitations such as:
those arising from the problem of repeatability and control when using living material
the difficulties of generalizing from research based on a single type of organism or environment.
Exceptions for Safety and Academic Honesty
Safety and Ethics in Choosing a Topic
In all cases where human subjects are used as the basis for an investigation, clear evidence of informed consent must be provided in accordance with the IB guidelines.
Some topics may be inadmissible because their means of investigation are unethical. For example, investigations that:
are based on experiments likely to inflict pain on, or cause stress to, living organisms
are likely to have a harmful effect on health, eg culturing micro-organisms at or near body temperature (37°C)
involve access to, or publication of, confidential medical information.
Some topics may be unsuitable because of safety issues. Adequate safety apparatus and qualified supervision is required for experiments involving dangerous substances such as:
toxic or dangerous chemicals
carcinogenic substances
radioactive materials.
Other topics may be unsuitable because the outcome is already well known and documented in standard textbooks.

Subject Options
a. Experiment-based essay: The focus with experiment-based essays is the primary data produced as a result of the experiment(s) conducted by students. Secondary sources in the form of scientific publications should be used to support a line of argument or indicate where the student has adapted their approach so as to produce different results. A consideration of the quality of the secondary source should also be offered to identify limitations or weaknesses in approach, method and so forth. Note: there are restrictions placed on the use of animals and humans when it comes to experiment-based essays. Check the IB Policy ‘Guidelines for the use of animals in IB World Schools’.
b. Non-experiment-based essay: Non-experiment-based (literature) essays should effectively question the reliability of the secondary source material used, and offer some insight into the strengths and limitations of the methodological approaches taken by the secondary sources.

Researching and writing an IB Extended Essay in Biology
Mr James Fraser, Head of Science at Scarborough College , shares some of the Extended Essay topics that he's had the pleasure of supervising.
The Extended Essay is a compulsory component of the IB Diploma. Students are tasked with writing four thousand words on a topic of their choice relating to one of the subjects they are studying for their Diploma. Every student is allocated a supervisor who will guide them through the process. It is not an exaggeration when I say that supervising students completing their Extended Essay in my subject has been the most rewarding part of my teaching role at the College.
I have had the privilege of supervising more than thirty students since the IB was introduced at the College more than ten years ago. When I cast my mind back, some topics and essays immediately spring to mind. For instance, the research undertaken by a student to investigate the response made by the tiny C. elegans worm to being tapped on the head. After we had acquired the worms from the University of Chicago, the student designed an ingenious device to tap the head of the worms using her own eyelash. I am sure the experience of conducting research for her Extended Essay in the College laboratory was an instrumental reason for her choosing to read for an immunology degree at the University of Glasgow before doing a PhD at Melbourne University.
More recently, a student now studying medicine at university, designed an investigation to genetically modify bacteria cultured in the lab with a gene originally obtained from jellyfish. The gene taken up by the transgenic bacteria caused them to fluoresce when exposed to ultraviolet light. The gene was prepared in a number of different ways to see if this had an effect on its uptake by the bacteria.
Our current Upper Sixth students have recently submitted their Extended Essays. A variety of topics were chosen for investigation by biologists this time around including the effect of hair washing on the strength of hair and the frequency of visits to a bird feeder by House sparrows during the day.
Another essay written by Ksenia Ivanova focussed on the potential for the effect of an antibiotic to be enhanced when used in conjunction with a variety of different plant extracts. I asked Ksenia what advice she would give a student choosing a topic for their essay. She replied that 'Whichever topic you decide to explore, the key is to choose something that you really like and care about, so that your work would never be boring.'
The essays themselves are awarded a grade from A to E. Together with the grade for the Theory of Knowledge course, upto three additional IB Diploma points can be included in their overall IB Diploma score. However, the emphasis throughout the process is not solely on the outcome. Many former students have been in touch over the years to tell me how much their Extended Essay experience helped them when completing assignments and dissertations at university. They always comment on the head start they had over their peers who had studied for ‘A’ Levels who had no experience of academic writing at school.
Returning to my current students, they have discovered that the frequency of hair washing does NOT have an effect on its strength, House sparrows visit garden feeders more in the morning and early evening than at other times of day, and are much more likely to be male than female, and the growth of bacteria was inhibited more when an antibiotic was used together with either clove oil or clary sage extracts than when it was used on its own.

Extended essay frame and word citation tool.
Posted by Stephen
Here’s a document we are using in my Extended Essay group . The intention is that students set it up from day 1, keeping all of their reading and research in a section at the end which will allow them to build their citations database. This section of notes will be deleted before final submission, unless any of the resources they save are worthy of an appendix.
By this point, students have read the examiners’ reports for their subject area EE’s, looked at some excellent examples ( on sale in the IB store ) and have read carefully through the EE guide, noting the subject-specific guidance for each criterion.
At the end of the document is a set of rubrics for self-assessment, which they should refer to on a regular basis. I have set it up so that they can add their own checkboxes above each rubric, listing what is most important for them to achieve.
There is a screencast below the document which gives a very quick introduction to using the Word citation manager.
Check out these great resources from Purdue’s OWL project on APA citation .
What I would love to see
If I could make one request of the IB, it would be that rolled into our programme fees for DP we could have access to university-style academic searches and journals. Wouldn’t it be great if the IB subscribed to the journals and schools could access them through Athens or Springerlink (or something else), to use in EE’s and research?

Whether it's biology or physchology doesn't matter so much in an extended essay as the need for the student to have a testable hypothesis and an argument which can be developed following the collection of data from a well controlled biology experiment.

Biology is the science that deals with living organisms and life processes. A biology EE should incorporate biological theory and emphasize why it is relevant today. The topic must relates specifically to biology. Many topics can be approached from different viewpoints, but for an EE in biology the treatment of the topic must be clearly biological.
