The Complete IB Extended Essay Guide: Examples, Topics, and Ideas

International Baccalaureate (IB)

IB students around the globe fear writing the Extended Essay, but it doesn't have to be a source of stress! In this article, I'll get you excited about writing your Extended Essay and provide you with the resources you need to get an A on it.

If you're reading this article, I'm going to assume you're an IB student getting ready to write your Extended Essay. If you're looking at this as a potential future IB student, I recommend reading our introductory IB articles first, including our guide to what the IB program is and our full coverage of the IB curriculum .

IB Extended Essay: Why Should You Trust My Advice?

I myself am a recipient of an IB Diploma, and I happened to receive an A on my IB Extended Essay. Don't believe me? The proof is in the IBO pudding:

If you're confused by what this report means, EE is short for Extended Essay , and English A1 is the subject that my Extended Essay topic coordinated with. In layman's terms, my IB Diploma was graded in May 2010, I wrote my Extended Essay in the English A1 category, and I received an A grade on it.

What Is the Extended Essay in the IB Diploma Programme?

The IB Extended Essay, or EE , is a mini-thesis you write under the supervision of an IB advisor (an IB teacher at your school), which counts toward your IB Diploma (learn more about the major IB Diploma requirements in our guide) . I will explain exactly how the EE affects your Diploma later in this article.

For the Extended Essay, you will choose a research question as a topic, conduct the research independently, then write an essay on your findings . The essay itself is a long one—although there's a cap of 4,000 words, most successful essays get very close to this limit.

Keep in mind that the IB requires this essay to be a "formal piece of academic writing," meaning you'll have to do outside research and cite additional sources.

The IB Extended Essay must include the following:

• A title page
• Contents page
• Introduction
• Body of the essay
• References and bibliography

Additionally, your research topic must fall into one of the six approved DP categories , or IB subject groups, which are as follows:

• Group 1: Studies in Language and Literature
• Group 2: Language Acquisition
• Group 3: Individuals and Societies
• Group 4: Sciences
• Group 5: Mathematics
• Group 6: The Arts

Once you figure out your category and have identified a potential research topic, it's time to pick your advisor, who is normally an IB teacher at your school (though you can also find one online ). This person will help direct your research, and they'll conduct the reflection sessions you'll have to do as part of your Extended Essay.

As of 2018, the IB requires a "reflection process" as part of your EE supervision process. To fulfill this requirement, you have to meet at least three times with your supervisor in what the IB calls "reflection sessions." These meetings are not only mandatory but are also part of the formal assessment of the EE and your research methods.

According to the IB, the purpose of these meetings is to "provide an opportunity for students to reflect on their engagement with the research process." Basically, these meetings give your supervisor the opportunity to offer feedback, push you to think differently, and encourage you to evaluate your research process.

The final reflection session is called the viva voce, and it's a short 10- to 15-minute interview between you and your advisor. This happens at the very end of the EE process, and it's designed to help your advisor write their report, which factors into your EE grade.

Here are the topics covered in your viva voce :

• A check on plagiarism and malpractice
• Your reflection on your project's successes and difficulties
• Your reflection on what you've learned during the EE process

Your completed Extended Essay, along with your supervisor's report, will then be sent to the IB to be graded. We'll cover the assessment criteria in just a moment.

We'll help you learn how to have those "lightbulb" moments...even on test day!  

What Should You Write About in Your IB Extended Essay?

You can technically write about anything, so long as it falls within one of the approved categories listed above.

It's best to choose a topic that matches one of the IB courses , (such as Theatre, Film, Spanish, French, Math, Biology, etc.), which shouldn't be difficult because there are so many class subjects.

Here is a range of sample topics with the attached extended essay:

• Biology: The Effect of Age and Gender on the Photoreceptor Cells in the Human Retina
• Chemistry: How Does Reflux Time Affect the Yield and Purity of Ethyl Aminobenzoate (Benzocaine), and How Effective is Recrystallisation as a Purification Technique for This Compound?
• English: An Exploration of Jane Austen's Use of the Outdoors in Emma
• Geography: The Effect of Location on the Educational Attainment of Indigenous Secondary Students in Queensland, Australia
• Math: Alhazen's Billiard Problem
• Visual Arts: Can Luc Tuymans Be Classified as a Political Painter?

You can see from how varied the topics are that you have a lot of freedom when it comes to picking a topic . So how do you pick when the options are limitless?

How to Write a Stellar IB Extended Essay: 6 Essential Tips

Below are six key tips to keep in mind as you work on your Extended Essay for the IB DP. Follow these and you're sure to get an A!

#1: Write About Something You Enjoy

You can't expect to write a compelling essay if you're not a fan of the topic on which you're writing. For example, I just love British theatre and ended up writing my Extended Essay on a revolution in post-WWII British theatre. (Yes, I'm definitely a #TheatreNerd.)

I really encourage anyone who pursues an IB Diploma to take the Extended Essay seriously. I was fortunate enough to receive a full-tuition merit scholarship to USC's School of Dramatic Arts program. In my interview for the scholarship, I spoke passionately about my Extended Essay; thus, I genuinely think my Extended Essay helped me get my scholarship.

But how do you find a topic you're passionate about? Start by thinking about which classes you enjoy the most and why . Do you like math classes because you like to solve problems? Or do you enjoy English because you like to analyze literary texts?

Keep in mind that there's no right or wrong answer when it comes to choosing your Extended Essay topic. You're not more likely to get high marks because you're writing about science, just like you're not doomed to failure because you've chosen to tackle the social sciences. The quality of what you produce—not the field you choose to research within—will determine your grade.

Once you've figured out your category, you should brainstorm more specific topics by putting pen to paper . What was your favorite chapter you learned in that class? Was it astrophysics or mechanics? What did you like about that specific chapter? Is there something you want to learn more about? I recommend spending a few hours on this type of brainstorming.

One last note: if you're truly stumped on what to research, pick a topic that will help you in your future major or career . That way you can use your Extended Essay as a talking point in your college essays (and it will prepare you for your studies to come too!).

#2: Select a Topic That Is Neither Too Broad nor Too Narrow

There's a fine line between broad and narrow. You need to write about something specific, but not so specific that you can't write 4,000 words on it.

You can't write about WWII because that would be a book's worth of material. You also don't want to write about what type of soup prisoners of war received behind enemy lines, because you probably won’t be able to come up with 4,000 words of material about it. However, you could possibly write about how the conditions in German POW camps—and the rations provided—were directly affected by the Nazis' successes and failures on the front, including the use of captured factories and prison labor in Eastern Europe to increase production. WWII military history might be a little overdone, but you get my point.

If you're really stuck trying to pinpoint a not-too-broad-or-too-narrow topic, I suggest trying to brainstorm a topic that uses a comparison. Once you begin looking through the list of sample essays below, you'll notice that many use comparisons to formulate their main arguments.

I also used a comparison in my EE, contrasting Harold Pinter's Party Time with John Osborne's Look Back in Anger in order to show a transition in British theatre. Topics with comparisons of two to three plays, books, and so on tend to be the sweet spot. You can analyze each item and then compare them with one another after doing some in-depth analysis of each individually. The ways these items compare and contrast will end up forming the thesis of your essay!

When choosing a comparative topic, the key is that the comparison should be significant. I compared two plays to illustrate the transition in British theatre, but you could compare the ways different regional dialects affect people's job prospects or how different temperatures may or may not affect the mating patterns of lightning bugs. The point here is that comparisons not only help you limit your topic, but they also help you build your argument.

Comparisons are not the only way to get a grade-A EE, though. If after brainstorming, you pick a non-comparison-based topic and are still unsure whether your topic is too broad or narrow, spend about 30 minutes doing some basic research and see how much material is out there.

If there are more than 1,000 books, articles, or documentaries out there on that exact topic, it may be too broad. But if there are only two books that have any connection to your topic, it may be too narrow. If you're still unsure, ask your advisor—it's what they're there for! Speaking of advisors...

Don't get stuck with a narrow topic!

#3: Choose an Advisor Who Is Familiar With Your Topic

If you're not certain of who you would like to be your advisor, create a list of your top three choices. Next, write down the pros and cons of each possibility (I know this sounds tedious, but it really helps!).

For example, Mr. Green is my favorite teacher and we get along really well, but he teaches English. For my EE, I want to conduct an experiment that compares the efficiency of American electric cars with foreign electric cars.

I had Ms. White a year ago. She teaches physics and enjoyed having me in her class. Unlike Mr. Green, Ms. White could help me design my experiment.

Based on my topic and what I need from my advisor, Ms. White would be a better fit for me than would Mr. Green (even though I like him a lot).

The moral of my story is this: do not just ask your favorite teacher to be your advisor . They might be a hindrance to you if they teach another subject. For example, I would not recommend asking your biology teacher to guide you in writing an English literature-based EE.

There can, of course, be exceptions to this rule. If you have a teacher who's passionate and knowledgeable about your topic (as my English teacher was about my theatre topic), you could ask that instructor. Consider all your options before you do this. There was no theatre teacher at my high school, so I couldn't find a theatre-specific advisor, but I chose the next best thing.

Before you approach a teacher to serve as your advisor, check with your high school to see what requirements they have for this process. Some IB high schools require your IB Extended Essay advisor to sign an Agreement Form , for instance.

Make sure that you ask your IB coordinator whether there is any required paperwork to fill out. If your school needs a specific form signed, bring it with you when you ask your teacher to be your EE advisor.

#4: Pick an Advisor Who Will Push You to Be Your Best

Some teachers might just take on students because they have to and aren't very passionate about reading drafts, only giving you minimal feedback. Choose a teacher who will take the time to read several drafts of your essay and give you extensive notes. I would not have gotten my A without being pushed to make my Extended Essay draft better.

Ask a teacher that you have experience with through class or an extracurricular activity. Do not ask a teacher that you have absolutely no connection to. If a teacher already knows you, that means they already know your strengths and weaknesses, so they know what to look for, where you need to improve, and how to encourage your best work.

Also, don't forget that your supervisor's assessment is part of your overall EE score . If you're meeting with someone who pushes you to do better—and you actually take their advice—they'll have more impressive things to say about you than a supervisor who doesn't know you well and isn't heavily involved in your research process.

Be aware that the IB only allows advisors to make suggestions and give constructive criticism. Your teacher cannot actually help you write your EE. The IB recommends that the supervisor spends approximately two to three hours in total with the candidate discussing the EE.

#5: Make Sure Your Essay Has a Clear Structure and Flow

The IB likes structure. Your EE needs a clear introduction (which should be one to two double-spaced pages), research question/focus (i.e., what you're investigating), a body, and a conclusion (about one double-spaced page). An essay with unclear organization will be graded poorly.

The body of your EE should make up the bulk of the essay. It should be about eight to 18 pages long (again, depending on your topic). Your body can be split into multiple parts. For example, if you were doing a comparison, you might have one third of your body as Novel A Analysis, another third as Novel B Analysis, and the final third as your comparison of Novels A and B.

If you're conducting an experiment or analyzing data, such as in this EE , your EE body should have a clear structure that aligns with the scientific method ; you should state the research question, discuss your method, present the data, analyze the data, explain any uncertainties, and draw a conclusion and/or evaluate the success of the experiment.

#6: Start Writing Sooner Rather Than Later!

You will not be able to crank out a 4,000-word essay in just a week and get an A on it. You'll be reading many, many articles (and, depending on your topic, possibly books and plays as well!). As such, it's imperative that you start your research as soon as possible.

Each school has a slightly different deadline for the Extended Essay. Some schools want them as soon as November of your senior year; others will take them as late as February. Your school will tell you what your deadline is. If they haven't mentioned it by February of your junior year, ask your IB coordinator about it.

Some high schools will provide you with a timeline of when you need to come up with a topic, when you need to meet with your advisor, and when certain drafts are due. Not all schools do this. Ask your IB coordinator if you are unsure whether you are on a specific timeline.

Below is my recommended EE timeline. While it's earlier than most schools, it'll save you a ton of heartache (trust me, I remember how hard this process was!):

• January/February of Junior Year: Come up with your final research topic (or at least your top three options).
• February of Junior Year: Approach a teacher about being your EE advisor. If they decline, keep asking others until you find one. See my notes above on how to pick an EE advisor.
• April/May of Junior Year: Submit an outline of your EE and a bibliography of potential research sources (I recommend at least seven to 10) to your EE advisor. Meet with your EE advisor to discuss your outline.
• Summer Between Junior and Senior Year: Complete your first full draft over the summer between your junior and senior year. I know, I know—no one wants to work during the summer, but trust me—this will save you so much stress come fall when you are busy with college applications and other internal assessments for your IB classes. You will want to have this first full draft done because you will want to complete a couple of draft cycles as you likely won't be able to get everything you want to say into 4,000 articulate words on the first attempt. Try to get this first draft into the best possible shape so you don't have to work on too many revisions during the school year on top of your homework, college applications, and extracurriculars.
• August/September of Senior Year: Turn in your first draft of your EE to your advisor and receive feedback. Work on incorporating their feedback into your essay. If they have a lot of suggestions for improvement, ask if they will read one more draft before the final draft.
• September/October of Senior Year: Submit the second draft of your EE to your advisor (if necessary) and look at their feedback. Work on creating the best possible final draft.
• November-February of Senior Year: Schedule your viva voce. Submit two copies of your final draft to your school to be sent off to the IB. You likely will not get your grade until after you graduate.

Remember that in the middle of these milestones, you'll need to schedule two other reflection sessions with your advisor . (Your teachers will actually take notes on these sessions on a form like this one , which then gets submitted to the IB.)

I recommend doing them when you get feedback on your drafts, but these meetings will ultimately be up to your supervisor. Just don't forget to do them!

The early bird DOES get the worm!

How Is the IB Extended Essay Graded?

Extended Essays are graded by examiners appointed by the IB on a scale of 0 to 34 . You'll be graded on five criteria, each with its own set of points. You can learn more about how EE scoring works by reading the IB guide to extended essays .

• Criterion A: Focus and Method (6 points maximum)
• Criterion B: Knowledge and Understanding (6 points maximum)
• Criterion C: Critical Thinking (12 points maximum)
• Criterion D: Presentation (4 points maximum)
• Criterion E: Engagement (6 points maximum)

How well you do on each of these criteria will determine the final letter grade you get for your EE. You must earn at least a D to be eligible to receive your IB Diploma.

Although each criterion has a point value, the IB explicitly states that graders are not converting point totals into grades; instead, they're using qualitative grade descriptors to determine the final grade of your Extended Essay . Grade descriptors are on pages 102-103 of this document .

Here's a rough estimate of how these different point values translate to letter grades based on previous scoring methods for the EE. This is just an estimate —you should read and understand the grade descriptors so you know exactly what the scorers are looking for.

Here is the breakdown of EE scores (from the May 2021 bulletin):

How Does the Extended Essay Grade Affect Your IB Diploma?

The Extended Essay grade is combined with your TOK (Theory of Knowledge) grade to determine how many points you get toward your IB Diploma.

To learn about Theory of Knowledge or how many points you need to receive an IB Diploma, read our complete guide to the IB program and our guide to the IB Diploma requirements .

This diagram shows how the two scores are combined to determine how many points you receive for your IB diploma (3 being the most, 0 being the least). In order to get your IB Diploma, you have to earn 24 points across both categories (the TOK and EE). The highest score anyone can earn is 45 points.

Let's say you get an A on your EE and a B on TOK. You will get 3 points toward your Diploma. As of 2014, a student who scores an E on either the extended essay or TOK essay will not be eligible to receive an IB Diploma .

Prior to the class of 2010, a Diploma candidate could receive a failing grade in either the Extended Essay or Theory of Knowledge and still be awarded a Diploma, but this is no longer true.

Figuring out how you're assessed can be a little tricky. Luckily, the IB breaks everything down here in this document . (The assessment information begins on page 219.)

Crafting the Perfect Extended Essay (EE): A Step-by-Step Structure Guide

The Extended Essay (EE) is a crucial component of the International Baccalaureate (IB) Diploma Program. It offers students a unique opportunity to conduct independent research on a topic of their choice and produce a structured academic paper. Proper structuring of the EE is essential for clarity, coherence, and meeting the IB's assessment criteria. Here’s a comprehensive guide on how to structure your Extended Essay effectively.

Attention: The Importance of Structure

Imagine trying to navigate a dense forest without a map. That's what reading an unstructured essay feels like. A well-structured EE not only helps the reader follow your argument but also demonstrates your organizational skills and attention to detail.

Interest: Components of a Well-Structured EE

A standard EE is typically composed of several key sections, each serving a distinct purpose. Here’s a breakdown of each section:

• Essential Information : Include the title of your essay, your name, IB candidate number, subject, and the date of submission.
• First Impressions : A clear and concise title page sets the tone for the rest of your essay.
• Summary : In about 300 words, summarize the research question, scope, methodology, and conclusions of your EE.
• Purpose : The abstract gives the reader a quick overview of what to expect in your essay.
• Navigation : List all the sections and sub-sections of your essay with corresponding page numbers.
• Organization : This helps the reader navigate through your essay easily.
• Context : Provide background information and set the context for your research.
• Research Question : Clearly state your research question and explain its significance.
• Thesis Statement : Outline the main argument or thesis of your essay.
• Existing Research : Summarize and evaluate the existing literature related to your topic.
• Gaps and Justification : Identify gaps in the existing research and justify the need for your study.
• Research Methods : Describe the methods you used to collect data, whether qualitative, quantitative, or mixed methods.
• Justification : Explain why these methods are appropriate for your research question.
• Procedure : Detail the steps taken during your research, including any experiments or surveys conducted.
• Thematic Organization : Divide this section into sub-sections based on themes or key points.
• Evidence and Analysis : Present your findings, analyze the data, and relate it to your research question and thesis.
• Critical Evaluation : Critically evaluate your findings and discuss their implications.
• Summary : Summarize the main findings of your research.
• Answer the Research Question : Clearly answer your research question based on the analysis.
• Implications and Recommendations : Discuss the broader implications of your findings and suggest areas for further research.
• Citations : Use a consistent citation style (such as APA, MLA, or Chicago) to list all the sources you referenced in your essay.
• Bibliography : Include a comprehensive list of all the sources you consulted during your research.
• Supplementary Material : Include any additional material that supports your research but is not essential to the main body (e.g., raw data, detailed calculations, survey instruments).

Desire: Tips for Effective Structuring

To ensure your EE is well-structured and meets the IB criteria, consider the following tips:

• Plan Ahead : Create a detailed outline before you start writing. This will help you organize your thoughts and ensure a logical flow.
• Stay on Topic : Each section should directly relate to your research question and thesis. Avoid including irrelevant information.
• Use Clear Headings : Use headings and subheadings to break down the content into manageable sections. This improves readability and helps the reader follow your argument.
• Be Concise : Stick to the word limit (usually around 4,000 words). Be clear and concise, avoiding unnecessary jargon or overly complex sentences.
• Edit and Revise : Revise your essay multiple times to improve clarity, coherence, and overall quality. Seek feedback from your supervisor and peers.

Action: Moving Forward with Confidence

With a clear structure in place, you are well on your way to writing a successful Extended Essay. Remember, the structure is your roadmap, guiding both you and your reader through the intricate journey of your research. Stick to this guide, and you'll produce an EE that is not only well-organized but also compelling and insightful.

Chemistry Extended Essay: Definition, Criteria, And Topics  

by  Antony W

October 30, 2023

This is the complete guide on IB Chemistry extended essay.

Whether you’re currently considering a subject to write your EE on or you’ve already made up your mind that you’ll write an extended essay on Chemistry, you’ll find this post useful.

What’s a Chemistry Extended Essay?

An extended essay in Chemistry offers you the chance to study a specific area of the environment’s components.

Within a more broad set of research standards, these lengthy, 4,000-word essays must highlight a particular aspect in the Chemistry subject.

The result of the study should be a logical and organized piece of writing that effectively tackles a certain subject or research question and reaches a specific, and ideally personal, conclusion.

What’s the Assessment Criteria for Chemistry EE?

The following is the assessment criteria used for Chemistry extended essay:

Criterion A: Research Question  

The research question of your Chemistry extended essay must be distinct and narrowly focused, relevant to the field of study, and centered specifically on the subject.

Criterion B: Introduction

The objective of the introduction is to contextualize the research topic. Present an underlying chemical theory required to comprehend how the research issue arose.

Criterion C: Investigation

For non-experimental essays, explain how you chose the data. Differentiate between primary sources and demonstrate an understanding of the reliability of each.  

For experimental tasks, provide sufficient information to allow independent researchers to replicate the experiment if necessary.

You should make it clear which experiments you have devised from scratch and which ones you have modified from existing methodologies.

Criterion D: Knowledge of the Topic

You must demonstrate a comprehensive understanding of the chemistry behind the setting of your research issue and subsequent study.

You don’t have to explain the fundamental chemistry covered in the chemistry course, but you should demonstrate that you have a clear understanding of the necessary concepts and can appropriately apply them.

Criterion E: Reasoned Argument

You should be aware of the necessity to provide a developing argument in the body of your writings.

Consideration and comparison of diverse methodologies and methods directly pertinent to the research issue will almost likely be a component of a convincing argument in chemistry.

Criterion F: Application Analysis & Skill Evaluation

Demonstrate a comprehensive comprehension of the dependability of the facts utilized to support the case. Identify inadequate experimental design or systemic flaws and mention the extent of physical data uncertainty.

Models should allow for approximations, and there should be a proper scrutinizing of all assumptions. Wherever feasible, use secondary sources or direct computations to verify the quality of sources accessed or data provided.

Criterion G: Language Choice

Use the correct chemistry language and nomenclature consistently and efficiently throughout the essay.

Criterion H: Conclusion

The conclusion must be consistent with the stated argument and should not just repeat information from the introduction or include new or irrelevant arguments.

Criterion I: Formal Presentation

Stick to the structure (or format) recommended for the Chemistry Extended Essay.

Criterion J: Abstract

The abstract is evaluated based on the clarity with which it provides a summary of the study and essay, not on the quality of the research question, argument, or conclusions.

Criterion K: Holistic Judgement

Make sure you attend all the extended essay reflections and have your supervisor comment on your EE.

How to Choose IB Chemistry EE Topics

Chemistry is the study of the composition, classification, and change of substances. Therefore, an extended essay in chemistry should include chemical principles and theory, and it should underline the core character of chemistry, which is the study of matter and its transformations.

1. Pick a Topic Specific to Chemistry

Although the same evaluation criteria apply to all extended essays, it is essential that the emphasis of the extended essay in this subject be on chemistry and not on another subject. In other words, the topic you choose for a chemistry extended essay must provide a chemistry-based approach treated from a chemical standpoint.

2. Your Topic Should Be Very Specific

The topic’s breadth and accompanying research should allow for the consideration of all criteria.

An excellent subject is one that focuses on a single research question and adequately addresses the issue within the 4,000-word limit. 

Perhaps the most crucial component is your ability to provide an in-depth analysis of the issue.

Broad or complex topics will not allow you to discuss opposing ideas and theories or produce an in-depth personal analysis within the word limit.

3. Avoid Topics Linked to Health and Safety Concerns

Some topics may not be acceptable for examination due to safety concerns. For example, you should avoid experiments that involves the use of poisonous or hazardous chemicals, carcinogenic compounds, or radioactive materials unless suitable safety equipment and competent supervision are available.

Other topics may not be appropriate since there’s already a documentation of the outcome. Such topics don’t leave room for personal involvement.

How Should You Treat Your Chemistry Extended Essay Topic?

You can base your Chemistry extended essay on literature, theoretical models, or empirical evidence.

Regardless of the category or combination of categories you choose, you must verify that adequate data is available for review and you can explore the issue by utilizing locally accessible resources.

If you choose to write an extensive essay based on literature or surveys, you must ensure the essay’s chemical foundation is evident.

Since chemistry is an experimental discipline, you are highly encouraged, but not required, to do experiments as part of their studies. Before beginning experimental work, you should conduct background study on the topic to conduct your research within the right framework.

If you include experiments in your work, you’ll need to go a step further to provide a clear and succinct description of the experiment. You should explicitly specify whether you devised the experiment yourself, or provide the source of an existing experiment technique you utilized and explain how you changed and enhanced it.

Examples of the Best Chemistry Extended Essay Topics

The following are examples of some of the best Chemistry extended essay topics for inspiration and direction:

• What effect does acid rain have on the trees, plants, and public gardens in your neighborhood?
• Analyze the chemical composition of various types of lava and magma rocks from across the world.
• Examine the short- and long-term consequences of vitamin deficiency in people.
• What kinds of chemical components are responsible for the majority of food allergies?
• Discuss the chemical changes that occur in aging human bodies.
• What effect do pesticides have on soil runoff and what do the facts say should be done?

Chemistry EEs need to emphasize the chemical aspects of the subject matter, incorporating chemical principles and theory, and emphasize the study of matter and of the changes it undergoes. (See the IB's  Chemistry: Subject-specific guidance .)

The following is a comparison of Chemistry EE topics to demonstrate the focus and specificity your topic should have.

(Source: Chemistry: Subject-specific guidance , IB)

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.

THE STRUCTURE OF THE ESSAY IS VERY IMPORTANT!

There’s an entire section of the markscheme dedicated to the structure and clarity of the essay ! Don’t ignore those marks! Below are the sections of a chem EE in order of what comes first etc. It may seem like this is a waste of time (me writing this) but there’s not a clear structure anywhere really so I struggled with the structure of mine.

A TITLE PAGE

Nothing more, nothing less than this. If you’re using MLA8 formatting, then this should be 12 point Arial. International Baccalaureate Extended Essay – Chemistry Research Question: ___ Word Count: ___

AN ABSTRACT ( OPTIONAL )

A contents page, set up an automatic contents page using word.

I suggest that you start a contents page on word early. Don’t manually make one, let Word do it for you.

Let Word help you make a contents page. Once it’s set up, it makes life so much easier for you.

Then all you have to do is use the ‘Headings’ to organise your contents page.

This makes it much easier to format and organise your EE , especially if you’re starting a new section.

ORGANISE YOUR SECTIONS BY NUMBER

Split your EE into chunks.  It improves clarity if your contents page is also organised by number . It doesn’t matter if some sections are small and are all on the same page, it still makes it way easier.

This is a part of my contents page. I don’t want to show you all of it because otherwise I’ll plagiarize myself (this is a May 19 session EE)

OUTLINE OF THE INVESTIGATION

Research question.

• State the independant and dependant variables
• Make it as short as possible without missing out any key details e.g. a certain method

INTRODUCTION

• What real life application does your topic/question have?
• Are any of the techniques you’re using used commonly in industry ?
• (again) Is it used in industry ?
• Is there a lot of research in the area? (If not then good)
• Talk about this only briefly , the bulk of this sort of stuff should go in the RPPF

BACKGROUND RESEARCH

This is where the bulk of the chemistry should be. This section should also account for about 1/4 of the entire essay . There’s more information about where to do background research here:

• e.g. colourimetry , etc
• Explain them in this section.
• Don’t put your real calculations here though
• They’re not included in the word count so put as many as you like

PRELIMINARY TRIALS

• What options did you have , and why did you chose this method ?
• How did you fix the problem/s?
• Any preliminary data you collected
• The better your reasons for your changes, the better your  Criterion C  mark (critical thinking)

JUSTIFICATION OF METHODOLOGY

Your pre-trials will determine the methodology for the real data collection of the EE. Take notes on your observations and why you made changes to the original experiment. All this stuff should go under this section.

EXPERIMENTAL VARIABLES

This section should be split into two parts, the experimental variables themselves and the justification for them

• State your variables (Independant, dependant, controls)
• Explain how you controlled them /kept them constant

JUSTIFICATION OF EXPERIMENTAL VARIABLES

• Link it to your introduction
• Easier to measure?
• More accurate?
• Large effect on the results?
• More detail as to how these variables were controlled throughout the experiment

METHODOLOGY AND JUSTIFICATION

Detail, but not too much detail

• Don’t list simple lab glassware (e.g. beakers or conical flasks )
• List any measuring equipment used, along with the uncertainty (e.g. ±0.5 cm3)

Again, detail but not too much detail

• Don’t list volumes of water used – water will always be in the lab.
• List exact volumes , masses and concentrations of all chemicals used, and uncertainties in their concentrations .

METHODOLOGY

• Clear enough that anyone with the same knowledge of chemistry as you could understand it.
• This is also a bulky section of the EE, a good place to cut down words…
• Do list volumes of water used in steps – this is important because you need to know volumes of water for washings or dilutions
• The more ( necessary and useful )detail is in this section, the better.
• How you should consider those hazards in the lab (e.g. wear eye protection at all times)
• How to deal with any spillage , leak or accidental consumption (or non accidental if you take HL maths)
• Cite these hazards!

DATA ANALYSIS

• Full results including anomalies
• Also including control variables you have measured (e.g. temp of the lab as a control)
• Relevant graphs showing relationship between two variables
• Examples and explanations of any calculations you’ve done
• Is it in line with what should theoretically happen or does it deviate?

IMPORTANT NOTES:

•   THE APPENDIX IS NOT REQUIRED READING FOR AN EXAMINER .  Don’t put anything in there that is essential for any arguments you have made.
• Reference your appendix in your essay (especially in data analysis ). If you’ve drawn a graph, underneath write something like  Data plotted in this graph can be found on pg. 30 (section 9.13) in the appendix.

(This is why I suggest organising the sections of your EE by number so you can easily reference back)

THE APPENDIX SHOULD INCLUDE:

• Tables of data that have been represented in graphs

IB Extended Essay: 300+ Ideas And Guide

What is the ib extended essay.

The IB Extended Essay (EE) stands as one of the cornerstones of the International Baccalaureate Diploma Programme (IBDP). Acting as an independent research task, the EE challenges students to investigate a topic of personal interest within the confines of the IBDP subjects they're engaged in. This endeavor, while rigorous, serves multiple purposes. Not only does it enhance students' analytical, critical thinking, and research prowess, but it also equips them with skills sought after by tertiary institutions and employers alike.

Spanning up to 4,000 words, the Extended Essay might seem daunting initially. However, its essence is about in-depth exploration. Think of it as a scholarly work that provides you with a unique chance to delve deep into a subject, test hypotheses, and showcase your understanding. The final output isn't just the essay, but also a formal presentation or viva voce, which promotes reflective learning and celebrates the culmination of this academic journey.

Given its weightage, the EE often becomes a differentiator for students when applying to competitive university programs. It showcases dedication, commitment to academic rigor, and the ability to synthesize large amounts of information into a coherent, persuasive piece of scholarly writing. For a more comprehensive overview, refer to the official IB page that dives into the nuances of the Extended Essay.

How to Choose Your Extended Essay Research Question?

A pivotal step in the Extended Essay process is the formulation of a pertinent research question. This question becomes the anchor of your entire essay, influencing your research, analysis, and conclusions. Here's a structured approach to help you craft the perfect research question:

• Passion and Interest: It's essential to select a topic you're genuinely curious about. Your engagement level will influence the depth of research and the overall quality of the essay.
• Scope and Feasibility: While it's tempting to tackle a broad issue, the 4,000-word limit necessitates focus. Your topic should be specific enough to be covered comprehensively within the word count, but not so narrow that it lacks depth.
• Relevance to Course Material: Ensure that your question aligns with the IBDP subject under which you're submitting. This not only ensures adherence to guidelines but also leverages the knowledge you've gained during your course.
• Availability of Resources: Before finalizing a topic, conduct preliminary research to gauge the availability of primary and secondary resources. The depth of your essay depends heavily on the quality of your sources.
• Originality: While you don't need to choose a never-before-explored topic, adding a unique perspective or angle to existing discussions can make your essay stand out.
• Consultation with IBDP Tutors: Engage with your IBDP tutors or teachers. Their experience and insights can guide you in refining your research question.

How to Write a Great IB Extended Essay

Writing an extended essay requires meticulous planning and a structured approach. Here are some key steps to enhance the quality of your essay:

• Start Early: Given the complexity and depth required, it's prudent to begin your research and planning months ahead of the submission deadline. This allows ample time for thorough research, drafting, and revisions.
• Create a Detailed Outline: Before diving into the writing process, draft a detailed outline. This will serve as a roadmap, ensuring a logical flow of ideas and comprehensive coverage of all facets of your topic.
• Use Varied and Credible Sources: Diversify your research by including books, academic journals, interviews, and reputable online sources. Always assess the credibility of your sources to ensure accurate and unbiased information.
• Stay Objective and Analytical: While it's tempting to infuse personal opinions, the Extended Essay demands an objective stance. Your assertions should be backed by concrete evidence, and opposing viewpoints should be fairly represented and analyzed.
• Seek Feedback: Periodically, share your drafts with peers, teachers, or IB tutors . External perspectives can offer invaluable insights, pointing out gaps or areas for improvement.

Finding Reliable Sources for Your Extended Essay

Quality research hinges on credible sources. Here's how to distinguish between reliable and dubious sources:

• Evaluate the Author's Credentials: Check the author's qualifications and affiliations. Experts in the field are more likely to produce accurate and unbiased content.

The IB Extended Essay Assessment Criteria and Grading

The International Baccalaureate (IB) Extended Essay is not just about writing a long research paper; it's about meeting specific assessment criteria to achieve the best grade possible. To excel, understanding these criteria is paramount. Let’s delve deeper into how the IB evaluates and grades the Extended Essay:

1. Focus and Method (6 marks): This criterion assesses the topic's significance, how well the research question is formulated, and the methodology used. Clearly defining your topic and choosing an appropriate and effective method is crucial. For instance, an essay analyzing a literary theme would differ methodologically from one exploring a scientific hypothesis.

2. Knowledge and Understanding (6 marks): Demonstrating a comprehensive grasp of your chosen topic is vital. This involves showing that you understand the context, implications, and why your topic is significant. Remember, superficial knowledge won't cut it; depth is essential. Rely on primary sources and respected secondary sources to bolster your understanding.

3. Critical Thinking (12 marks): The highest marks are allocated here. You're evaluated on how well you analyze the information, the arguments you build, and the solutions or conclusions you derive. A well-thought-out essay isn't just descriptive; it evaluates, critiques, and synthesizes information.

4. Presentation (4 marks): While it might seem minor, presentation is crucial. This criterion involves the overall structure of the essay, the clarity of your writing, and adherence to recognized academic standards, including referencing.

5. Engagement (6 marks): This is about your journey. The IB wants to see that you've engaged deeply with your topic, overcome challenges, and reflected on the research process. Often, the reflections you submit alongside your essay play a role in this assessment.

Together, these criteria amount to a total of 34 marks. Essays are then graded on a scale from A (excellent) to E (elementary). An 'E' in the Extended Essay is a failing condition for the award of the IB Diploma. Ensure you understand each criterion and address it adequately. More details on the assessment criteria can be found here .

Extended essay assessment criteria

This section provides an overview of what each criterion assesses in the extended essay. Further advice on interpreting the assessment criteria is provided within the guidelines for each subject in the subject specific section.

The extended essay is assessed against common assessment criteria for all extended essays. Candidates must understand that the work submitted for assessment must address these criteria effectively. Supervisors of extended essays should ensure that the assessment criteria are made available to candidates and that the candidates understand these criteria.

A: research question - (Objectives 1 and 2)

This criterion assesses the extent to which the purpose of the essay is specified. In many subjects, the aim of the essay will normally be expressed as a question and, therefore, this criterion is called the research question. However, certain disciplines may permit or encourage different ways of formulating the research task.

B: introduction - (Objectives 1 and 5)

This criterion assesses the extent to which the introduction makes clear how the research question relates to existing knowledge on the topic and explains how the topic chosen is significant and worthy of investigation.

C: investigation - (Objectives 1 and 3)

This criterion assesses the extent to which the investigation is planned and an appropriate range of sources has been consulted, or data has been gathered, that is relevant to the research question. Where the research question does not lend itself to a systematic investigation in the subject in which the essay is registered, the maximum level that can be awarded for this criterion is 2.

D: knowledge and understanding of the topic studied - (Objectives 3 and 7)

Where the research question does not lend itself to a systematic investigation in the subject in which the essay is registered, the maximum level that can be awarded for this criterion is 2. “Academic context”, as used in this guide, can be defined as the current state of the field of study under investigation. However, this is to be understood in relation to what can reasonably be expected of a pre-university student. For example, to obtain a level 4, it would be sufficient to relate the investigation to the principal lines of inquiry in the relevant field; detailed, comprehensive knowledge is not required.

E: reasoned argument - (Objectives 1 and 4)

This criterion assesses the extent to which the essay uses the material collected to present ideas in a logical and coherent manner, and develops a reasoned argument in relation to the research question. Where the research question does not lend itself to a systematic investigation in the subject in which the essay is registered, the maximum level that can be awarded for this criterion is 2.

F: application of analytical and evaluative skills appropriate to the subject - (Objective 7)

G: use of language appropriate to the subject - (Objective 6)

H: conclusion - (Objectives 1, 4 and 5)

This criterion assesses the extent to which the essay incorporates a conclusion that is relevant to the research question and is consistent with the evidence presented in the essay.

I: formal presentation - (Objective 5)

This criterion assesses the extent to which the layout, organization, appearance and formal elements of the essay consistently follow a standard format. The formal elements are: title page, table of contents, page numbers, illustrative material, quotations, documentation (including references, citations and bibliography) and appendices (if used).

J: abstract - (Objective 5)

The requirements for the abstract are for it to state clearly the research question that was investigated, how the investigation was undertaken and the conclusion(s) of the essay.

K: holistic judgment - (Objective 1)

The purpose of this criterion is to assess the qualities that distinguish an essay from the average, such as intellectual initiative, depth of understanding and insight. While these qualities will be clearly present in the best work, less successful essays may also show some evidence of them and should be rewarded under this criterion.

Notes from the IB

RE: Research Question and Title of Extended Essay

Please note the statement below from the EE curriculum manager regarding the need to have both a title and a RQ for all subjects. Previous versions of the EE Guide indicated that the title and the RQ should be the same for History, Business Management and Mathematics. This is no longer the case.  All essays, regardless of the subject, need to have both a RQ and a title.

Hi Kathy, 

To answer your question, I am going to quote directly from a response John Royce provided, on this forum, in October in response to a very similar question: (it was a question about using Spanish sources - hence the mention of Spanish)

It is certainly  permissible to use sources which are not in the language of the essay, but translation into the target language is required , one cannot assume that the reader understands the original language.

It is usual to quote the original as well as presenting the translation.  [Do not put quotation marks around your translation, just around the original]

Umberto Eco argues ("in Mouse or rat?") that direct translation may lose meaning, paraphrase or use of different idioms may be required to get the ideas across. Paul Bellos ("Is that a fish in your ear?") makes a similar argument - direct translation may confound meaning... Direct translation may not be ideal - meaning and understanding are preferred - so, not to worry that your student with her good Spanish cannot present a direct translation.

What  must be made clear is that the translations are those of the student;  these are her understandings. Readers can make of that what they will - and if unsure, are presented with the original - they can seek another translation.  A note in the acknowledgements and/or in the introduction to the effect that all translations are those of the writer is ... essential.

In response to the question about the  Bibliography/Works cited, my preference would be to list the source in its original Thai version, but perhaps with the English in brackets, to help the examiner.

Your bibliography will have the entries in Thai characters first in the document. Any in-text citation to Thai sources will be in (Thai characters [English translation]).

Format of the Extended Essay

Required Formatting

The extended essay should be written in a clear, correct and formal academic style, appropriate to the subject from which the topic is drawn. Given that the extended essay is a formally written research paper, it should strive to maintain a professional, academic look. 

To help achieve this, the following formatting is  required:

• 12-point, readable font (Calibri or Times New Roman);
• double spacing throughout entire Essay;
• page numbering - top right corner;
• no candidate or school name or supervisor name on the title page or page headers.

Submitting the extended essay in the required format will help set the tone of the essay and will aid readability for on-screen assessment by examiners.

Required S tructure

The structure of the essay is very important. It helps students to organize the argument, making the best use of the evidence collected. 

There are six required elements of the final work to be submitted. More details about each element are given in the  “Presentation”  section. Please note that the order in which these elements are presented here is not necessarily the order in which they should be written. 

Six required elements of the extended essay:

• Contents page
• Introduction
• Body of the essay
• References and bibliography -- if MLA "Works Cited" if CSE "References"

1. Required Title Page  

The title page should include  only  the following information: 

• the title of the essay
• the research question
• the subject the essay is registered in (if it is a language essay also state which category it falls into; if a world studies essay also state the theme and the two subjects utilized) 

The upper limit is 4,000 words for all extended essays. 

2. Required Contents Page

A contents page must be provided at the beginning of the extended essay and all pages should be numbered. Please note that an index page is not required and if included will be treated as if it is not present.

3. Required Introduction

The introduction should tell the reader what to expect in the essay. The introduction should make clear to the reader the focus of the essay, the scope of the research, in particular an indication of the sources to be used, and an insight into the line of argument to be taken. 

While students should have a sense of the direction and key focus of their essay, it is sometimes advisable to finalize the introduction once the body of the essay is complete.

4. Required Body of the Essay  (research, analysis, discussion, and evaluation)

The main task is writing the body of the essay, which should be presented in the form of a reasoned argument. The form of this varies with the subject of the essay but as the argument develops it should be clear to the reader what relevant evidence has been discovered, where/how it has been discovered and how it supports the argument. In some subjects, for example, the sciences, sub-headings within the main body of the essay will help the reader to understand the argument (and will also help the student to keep on track). In structuring their extended essay, students must take into consideration the expected conventions of the subject in which their extended essay is registered. 

Once the main body of the essay is complete, it is possible to finalize the introduction (which tells the reader what to expect) and the conclusion (which says what has been achieved, including notes of any limitations and any questions that have not been resolved). 

Any information that is important to the argument  must not  be included in appendices or footnotes/endnotes. The examiner  will not  read notes or appendices, so an essay that is not complete in itself will be compromised across the assessment criteria.

5. Required Conclusion

The conclusion says what has been achieved, including notes of any limitations and any questions that have not been resolved. While students might draw conclusions throughout the essay based on their findings, it is important that there is a final, summative conclusion at the end. This conclusion(s) must relate to the research question posed.

6.  Required References & Bibliography

Students should use their chosen style of academic referencing as soon as they start writing. That way they are less likely to forget to include a citation. It is also easier than trying to add references at a later stage. For more information on this, refer to the guidelines in the IB document  Effective citing and referencing.

Writing the essay takes time but if students have used their Researcher's reflection space and reflection sessions in a meaningful way they should be well prepared to develop their arguments.

Controlled synthesis of metastable materials away from equilibrium is of interest in materials chemistry. Thin-film deposition methods with rapid condensation of vapour precursors can readily synthesize metastable phases but often struggle to yield the thermodynamic ground state. Growing thermodynamically stable structures using kinetically limited synthesis methods is important for practical applications in electronics and energy conversion. Here we reveal a synthesis pathway to thermodynamically stable, ordered layered ternary nitride materials, and discuss why disordered metastable intermediate phases tend to form. We show that starting from elemental vapour precursors leads to a 3D long-range-disordered MgMoN 2 thin-film metastable intermediate structure, with a layered short-range order that has a low-energy transformation barrier to the layered 2D-like stable structure. This synthesis approach is extended to ScTaN 2 , MgWN 2 and MgTa 2 N 3 , and may lead to the synthesis of other layered nitride thin films with unique semiconducting and quantum properties.
