Biology EE Topics: How to Choose, Plus Good Examples
by Antony W
September 3, 2022
Have you scoured the web for Biology EE topics but came out empty? Or maybe you’ve considered writing an EE in the subject but you still have no idea what to focus your research on?
You’ve come to the right place.
In this guide, you’ll learn how to choose the best biology extended essay topic to explore in your assignment. In addition, we’ll give you some topic ideas as well as teach you how to treat the topic you choose.
What’s the Purpose of a Biology Extended Essay?
An extended essay in biology allows you to apply biological knowledge while conducting research on a topic of personal interest within the area of biology.
A concentration on biology within the framework of a broader scientific research is what defines the nature of a biology extended essay.
How to Choose Biology EE Topics
The following are important considerations to make when selecting a topic for your biology extended essay:
1. Select a Topic Focusing Strictly on Biology
Biology is the scientific discipline concerned with living beings and biological processes. Therefore, a biology extended essay should contain biological theory and underline the subject's fundamental character.
It is essential that the emphasis of the extended essay be clearly biological and not more closely connected to another subject.
Although identical grading criteria apply to all extended essays in the experimental sciences, the topic you choose for a biology extended essay must provide a distinct biological perspective.
2. Avoid Topics That May Cause Harm
Certain topics are inappropriate for research due to ethical concerns. Investigations based on trials that are likely to cause pain or needless stress to living beings are ineligible for submission.
Investigations that are likely to have a negative impact on health, such as microorganism cultivation at or near body temperature, or that may require access to or release of personal medical information are inappropriate.
Some topics may not be acceptable for examination due to safety concerns.
You need to avoid experiments involving the use of poisonous or hazardous chemicals, carcinogenic compounds, or radioactive materials, unless proper safety equipment and trained supervision are available.
3. Avoid Obvious Topics
Other topics may be inappropriate because the conclusion is already well known and documented in standard textbooks.

How to Analyze Your Biology Extended Essay Topic
You should explain early in the essay how you formulated the research topic and, if applicable, how you narrowed it by briefly elaborating on any relevant elements.
You should develop one or more hypotheses, especially since a single, well-formulated inquiry can generate a handful of specific hypotheses.
It’s possible to base your biology extended essays on data obtained through experiments, survey, microscopic observations, biological sketching, fieldwork, or any acceptable biological method.
Alternately, you can base the essay on facts or information collected from literature, ideally from primary sources, then alter or analyze in an innovative way.
If you’re working on an essay that requires laboratory or fieldwork test, you should provide a clear and brief description of the experimental methodology.
Explain how you chose the research technique and methodology, as well as any options that you investigated but rejected.
Final Thoughts
Now that we’ve given you a list of 10+ Biology extended essay topics, it should be easy for you to identify an area to explore.
It can be an area you’re always interested in or a topic that you’ve always wanted to explore.
You should do research for your essay under the direct supervision of a supervisor.
Regardless of where or under what conditions you conduct studies, you must demonstrate your personal contribution to the research methodology and selection of methodologies in the essay.
Generating and presenting data should not be a goal in and of itself. Remember, proper scientific analysis is vital.

Your essay writing can be fascinating if you select an appropriate topic of biology. You might have awesome writing skills, but a poor topic choice may be the reason for your failure. There are a few factors to consider when choosing the subject. First, are you familiar enough with the content addressed by the topic? Secondly, do you have access to resources regarding your research? One more thing to consider is a level of interest to your topic. It is essential that you take your time in picking the appropriate biology extended essay topics depending on the area you want to research on.
How to Select the Best Biology Essay Topic?
One of the biggest challenges students face in school is picking a right topic for their essays . Making the decision is in no way the simplest of things, considering the critical role which extended essay biology topics play in an essay. However, there are several ways you can pick an awesome topic, one that will steer you towards producing a great paper.
- First, go for a topic that is within your complexity level. Many students make the mistake of choosing complex topics that surpass their capacity and academic level, perhaps to impress the instructor. What happens in such a situation is that a student writes a paper that is without eloquence, shallow in content, and unimpressive. It is better you pick a simple topic that you can tackle exhaustively , giving irrefutable facts and solid arguments.
- Secondly, pick a topic that captures your attention. Otherwise, you’ll get bored when writing, and you won’t be able to give it your best.
On the other hand, when writing on a topic that interests you, all your heart will be in it, and therefore you are likely to do it excellently. Lastly, be on the look for controversial biology-related stories. These are great areas to research and write your essays, as they already interest your readers in biology class.

160 Biology Essay Topics
For most science courses, assignments are generally lab-based and rarely require much writing. However, all of that changes in biology courses when detailed essays must be written to highlight a student’s understanding of the subject. These essays are highly technical, with specific comments required to meet the factual nature of the subject.
In addition to meeting the factual requirements needed to complete the assignment, biology essays must also be written in a writing style that is informative and authoritative rather than subjective and personal.
These detailed specifics of writing a biology essay can make completing the writing difficult from the very beginning. Fortunately, we’ve created this guide to help students learn how to write a biology essay. In addition, we’ve also included 160 biology essay topics to help inspire the creative writing process.
How to Write a Biology Essay?
Writing a biology essay starts with choosing a topic. If your teacher has not already assigned a specific topic, then students must choose one that is broad enough to find credible resources and specific enough that the research won’t overtake the writing process.
To select a suitable topic for a biology essay, consider the type of biology class you are taking, the current and previous chapters studied, and the overall context of the course. These factors will help you select a topic that is likely to be relevant to your teacher’s needs and to the passing of your course.
Once students have selected a suitable topic, it’s time to research credible resources that will support the subject. To do this successfully, students need to consider the following:
- What information is already known about this topic?
- What topics are related or similar to this topic?
- Who are credible authors that can explain this topic?
- What additional sources will provide me with the information needed to complete this assignment successfully?
For example, if you want to write a biology essay on protein synthesis and its regulation at the transcriptional level, research material would include books, articles, and other written works published by credible authors or publishers. While important, this material isn’t the only type of research that should be completed.
Students may also consider consulting medical and biology dictionaries, textbooks, online research databases such as PubMed or Medline, and professional organizations for biologists to find additional sources. Once the research has been completed, it’s time to create the first draft of the biology essay.
Biology Essay Introduction
Starting an essay is always the same. Students should open with a catchy hook statement that introduces an interesting fact, presents a unique perspective, or raises a thought-provoking question.
Once that sentence has been created, students can use the middle part of the introduction to introduce fundamental concepts and provide background details about the topic.
Once that information has been laid out, and the reader knows the necessary details to make the reading interesting and worthwhile, students should move into the final portion of the introduction that answers the question: WHY is this essay important? This question is answered in the form of a thesis statement that details the essay’s overall purpose.
Biology Essay Body Paragraphs
The body paragraphs of your essay will contain the bulk of your research. Be sure that each body paragraph meets the following requirements:
- One clear idea represented per paragraph or section
- Examples that back up the point of the paragraph
- A clear and logical flow between paragraphs with transition words
Make sure that the body paragraphs only contain information pertinent to the subject or topic. Avoid fluff or filler words and phrases that don’t add any substance or value to the writing.
The number of paragraphs in the body may vary depending on the assignment parameters and the essay style. For example, an essay with a 1000 word limit won’t have as many body paragraphs as an essay with a high word count.
Additionally, a compare and contrast essay that examines the similarities and differences between two or more biology concepts may have more body paragraphs than an argumentative essay.
Biology Essay Conclusion
The final section of a biology essay is the conclusion. In this section, students need to summarize the major points of the essay and the overall purpose for writing it. The thesis should also be re-stated to recap what has been learned from the writing.
In addition to these sentences, students should include a final remark about their research and findings. This might be a thought that ties into the intro or another interesting angle that presents a new way of looking at your topic.
Once the conclusion is completed, students should edit and review their work. Make sure that the essay is free of grammar and spelling mistakes before submitting it for grading.
When it comes to choosing a biology essay topic, it is not always as easy as it seems. For students looking for help with writing a biology essay, we have compiled a list of 160 biology essay topics that will hopefully give you some great ideas.
