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:

body_ibeescore.png

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.

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...

body-narrow-crack-stuck-cc0-pixabay

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!

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.

body-theory-of-knowledge

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.)

physics extended essay

In this guide, you’ll learn everything you need to know about Physics Extended Essay in IB. We’ll look at:

  • What Physics EE is all about
  • How to choose a topic
  • The right approach to handling your topic and
  • Physics EE assessment criteria

What’s Physics EE in IB?  

A physics extended essay is an individual assignment that requires you to utilize a variety of abilities while exploring a topic of personal interest in the discipline of physics.

It focuses on physics within a broader set of scientific standards, and it takes the form of a research that incorporates a hypothesis or model, or a critical analysis that displays argumentation, comparison, or the extraction of pertinent information or data.

How to Choose a Physics Extended Essay Topic 

The first rule when it comes to topic selection is that you must put emphasis on a subject within physics.

In other words, IB students have to ground their extended essays in physical theory and underline the subject's essence.

To write a more comprehensive, extended essay in the subject, you should select a focused, practical, and well-defined topic that allows you to conduct an in-depth analysis.

Avoid broad or complicated subjects, because they will not allow you to explore contradictory views and hypotheses.

Also, a broad topic will not allow you to conduct an in-depth, personal interpretation within the word limit recommended for EE .

Additionally, you should avoid investigating issues that extend outside the bounds of mainstream science, such as metaphysics or pseudoscience. Examples include of investigative issues include:

  • Extrasensory experience
  • The relationship between physics and the existence of God
  • The mysterious forces of pyramids

The IB board considers it helpful if you can specify the subject further in the form of a research question, followed by a statement of purpose that indicates the approach you will employ to answer the question.

If you’re going to focus on an experimental essay, you will need to select a more practical experiment that does not need substantial amounts of time for equipment building.

In some instances, more advanced equipment might create constraints and inhibit the comprehension of a phenomenon. Successful trials will generate the data required for a sound analysis reasonably quickly.

Some Physics Extended Essay topics may not be acceptable for examination due to safety concerns.

For example, you need to avoid topics that requires experiments using hazardous or carcinogenic chemicals, radioactive materials, lasers, microwaves, ultraviolet light, noise, or heavy equipment.

How to Write a Physics Extended Essay

The primary goal of this type of assignment is to demonstrate a clear understanding of the topic you’ve selected to work on. So to ensure you write the best EE in the subject:

1. Choose the Right Angle to Direct Your Assignment

It’s important to note that your Physic extended essay will need to express an in-depth study into the history or theory of the particular topic. However, it’s different for long assignments I the subject.

For long subjects, you may focus on:

  • Experimental physics: This area focuses on the design and execution of an experiment, followed by personal data collecting and analysis.
  • Data based physics: It focuses on location and extraction of non-student-collected raw or processed data, which is subsequently refined and analyzed.
  • Theoretical physic: The focus is on the formulation of a quantitative or semi-quantitative description of a physical phenomenon, the application of the model, and the prediction of its behavior and limitations.
  • Survey: It involves the construction of a coherent, organized, analytic, and supported (qualitative and quantitative) discussion of the issue

All long physics essays should include an overview of the work's scope and limits.

This should always include a study of any experimental design, data uncertainties and accuracy, mathematical approaches, links to theoretical models, and the dependability and quality of sources.

2. Give a Direct Analysis of Your Research Topic

The essay's body and progression should directly analyze the research topic. 

Experimental essays can help students to demonstrate their critical thinking more clearly, but experimental activity aren’t necessary for the assignment.

However, you must provide a clear theoretical component for each empirical inquiry.

If you include any experimental effort in your Physics extended essay, ensure to document it thoroughly so that other researchers can produce it with identical findings and conclusions.

If you’ve opted to collect data from secondary sources, use it with extreme caution.

Ensure you provide a comprehensive evaluation of the location and credibility of the sources required for databased essays at the outset of the planning process.

You should apply the same scrutiny to this data and the experimental design as if you had gathered the data yourself.

3. Examine Your Research Techniques Thoroughly

A thorough examination of research techniques is necessary in a Physics extended essay.

That’s because it might reveal severe problems in experimental design or data collection that invalidate or at least limit the interpretation of the results completely or in part.

A purely empirical inquiry linking two or three variables without a theoretical basis is unsatisfactory.

For example, if you utilize a computer simulation of a theoretical model, you should extensively analyze the methods devised or implemented and you should compare simulated results to actual events to determine their validity.

If you’re going to write an essay that contains a theoretical model that describes a physical occurrence, your planning should include the beginning postulates, the important stages for running the model, and the simulation results collected.

4. Explain Your Literary Sources Thoroughly

In theoretical, data based, or survey extended essay in Physics, you must include an assessment of the quality and dependability of the literary sources.

You have to have sufficient knowledge of the issue to evaluate the credibility of the sources.

You can accomplish this by researching secondary sources or calculating independently.

Also, you should not be hesitant to discuss opposing viewpoints and share your own thoughts with supporting evidence.

In survey or theoretical essays, appropriate preparation requires examining source material in light of the research topic so that you utilize the opinions of other scientists to support your own thesis, rather than as a replacement for it.

5. Make Your Analysis Clear and Concise

An analysis must supplement data or information rather than merely duplicate it. And you need to make sure you derive interpretations logically from facts or information. 

Your essay needs to include the avoidance of unfounded, far-fetched extrapolation and the acknowledgement of flaws.

The commentary should not simply a restatement of the data. It should produce a strong interpretation of the results, which ones can compare to previously published research on the subject.

Physics Extended Essay Assessment Criteria

The following is the assessment criteria used to gauge the depth and comprehensiveness of your Physics Extended Essay:

Criterion A: Research Question

The criterion requires that your research topic must be relevant to physics as a science, centered on physics and not on ancillary problems, and clearly recognized and prominently presented in the introduction.

Criterion B: Introduction

The introduction should tie the research question to the existing body of knowledge on the topic.

You should not include your personal experience or viewpoint here, as it’s highly unlikely to be helpful at this point.

You should place the pertinent physics concepts within the context of the issue. You need to view the introduction as a chance to be more precise rather than appearing bloaty.

Criterion C: Investigation

The strategy you use for investigation should show a clear pertinent theory as well as an understanding of the inherent uncertainties and limits of procedures and equipment used in the Physics Extended Essay.

Criterion D: Knowledge and Understanding of the Research Issue

The knowledge and comprehension exhibited in a physics essay should go beyond the course or laboratory.

You have to demonstrate that you can use the essential information obtained in the classroom in a new physical environment that necessitates its interpretation.

Criterion E: Reasoned Argument

Students should be aware of the necessity to provide a developing argument in the body of their writings.

In order to persuade the reader of the correctness of one's opinions, you have to include logical and helpful arguments in your work.

Criterion F: Use of Analytical and Evaluative Skills

You must demonstrate a comprehension of the mathematical and statistical correlations automatically generated by systems.

It is necessary to have a thorough and firm awareness of the inherent constraints of an inquiry and their consequences for the results obtained.

Criterion G: Use of Language and Terminologies Relevant to the Subject

The usage of scientific terminology is required throughout your Physics Extended Essay.

To understand the right format, structure, and presentation of a scientific paper, you should study articles from reputable scientific journals and periodicals.

The essential quality of the language is exactness and common expressions such as "function of" and "proportional to" must have specific meanings. You should specify any symbols used in context.

Criterion H: Conclusion

Make sure that the conclusion of your Physics EE develops from the argument and not introduce new or irrelevant material.

It should not duplicate the information presented in the introduction, but rather give a new synthesis in light of the conversation.

The conclusion should indicate how uncertainties in experimental data, the constraints of a model or experimental design, or the reliability of sources affected the outcomes of your work.

Criterion I: Formal Presentation

This criterion addresses the extent to which the essay complies with academic norms about the format of research papers.

  • Extended Essay

The Extended Essay guide is the ultimate place to go for all official IB information on this aspect of the Diploma. This gives information about what your responsibilities are as an advisor, the assessment criteria and their clarifications for physics essays. On this site we summarise the requirements and reflect on some physics-specific requirements.

As a quick rule of thumb, remember 4 4 4:

  • 40 hours of work
  • 4 hours of meeting time

physics extended essay samples

The basic requirements of a physics essay make sense:

  • Develop an area of interest
  • Research a framework on which to conduct an investigation (e.g. an equation or law)
  • Data analysis

However, it is important to familiarise yourself and your student with other key aspects of the Extended Essay before kicking off.

Introduction

Towards the end of the first year of their Diploma Programme, all IB students at your school will start to choose their Extended Essay (EE) subject. Some of them might choose physics, which is where you come in! Your supervisee should already be familiar to you as a student of physics already (probably at Higher Level). Regardless of the subject chosen, the essay has a 4000 word limit and should conduct approximately 40 hours of research. This is the time when students get the chance to go deeper into a subject giving you the supervisor the chance to work on a more individual level with the keenest students (in theory!).

Having supervised about 100 essays in 20 years' of teaching the IB, Chris took up the challenge to have a go at doing one himself!  Here are his thoughts...

Although I didn't use the whole 40 hours the experience has given me a new insight into the process that I hope will be useful. Maybe my first piece of advice should be "go write one", its the best way to learn what it's about. My students thought it was pretty cool but wanted to know why I'd waited until they had submitted theirs. Anyway I submitted it to an experienced marker and got an A , now I feel ready to give advice to both supervisors and students. The essay used the same research question that an ex-student of mine had used, I remembered it to be a neat idea so thought I'd have a go at doing the experiments myself. Recently I met the student and he sent me his original essay and gave me permission to post it ( Dusan's essay ). Unfortunately a couple of the images are missing but it still makes sense. He also got an A and I have to admit that his analysis was more thorough than mine.

physics extended essay samples

This will take the form of 3 formal interviews:

  • The first will be early in the process, perhaps during the first hours of data collection and with a sample of writing. This is also to point to check that your supervisee has all the necessary skills for their project (ICT, data collection, research, referencing, writing).
  • The second is an interim meeting, in which you should be intellectually critical of the students' decisions to date and to advise them on the final steps to making a valid conclusion. However, it will probably be too late at this stage to amend the methodological approach.
  • The last is a viva voce, when the student has submitted a final draft of their work.

A written report must be completed by the student after each interview. These reports are signed by the supervisor with brief comments and are submitted to the IB along with the essay. They will be assessed and evidence of a good process with growth in sophistication can get the student 6 out of 34 marks.

Between meetings 2 and 3, you will formatively mark a near-complete draft of the student's work, but without being too prescriptive - there is exemplar guidance in the Guide on the sort of feedback permitted.

Ensure that you liaise regularly with your school's Diploma Coordinator for their in-house supervisor training or to agree to your local procedures (e.g. timing, deadlines).

There are five separate aims that are listed in the IB guide; these are what the student will gain by doing an EE. Essentially an Extended Essay provides the student with the opportunity to:

  • engage in independent research with intellectual initiative and rigour
  • develop research, thinking, self-management and communication skills
  • reflect on what has been learned throughout the research and writing process.

Tthe extended essay should be an opportunity to develop certain skills and experience what it is like to take part in research. It's an introduction to the sort of work that they will be involved in at university. The rest of the IB physics programme is focussed around passing the exam and learning how to fulfil assessment criteria, so this is a brilliant opportunity to go a bit beyond the constraints of the course (but not beyond the constraints of the EE criteria).

Many students will comment on how writing an EE has given them an advantage at university. They already know how to structure an essay, make references, insert diagrams, etc. The process of writing an EE enables the student to develop along the lines of the official aims although not all get to "experience the thrill and excitement".

Interestingly enough there is no mention in the aims of "giving the brilliant student the chance to excel" or "enabling the student to go way beyond the realms of the syllabus" but this is how the EE is sometimes portrayed and that misconception may even have found its way into the minds of some markers. Why would we expect students to be able to write an essay on topics not even touched on in class? The point is they are supposed to use the knowledge they possess to investigate something new. Of course there is nothing wrong with the brilliant student being able to extend their knowledge but this shouldn't be the norm.

There are 10 objectives required in order to meet the aims:

  • To demonstrate knowledge and understanding of the topic chosen and the research question posed.
  • To demonstrate knowledge and understanding of subject specific terminology and/or concepts.
  • To demonstrate knowledge and understanding of relevant and/or appropriate research sources and/or methods used to gather information.
  • To select and apply research that is relevant and appropriate to the research question.
  • To analyse the research effectively and focus on the research question.
  • To be able to discuss the research in terms of a clear and coherent reasoned argument in relation to the research question.
  • To be able to critically evaluate the arguments presented in the essay.
  • To be able to reflect on and evaluate the research process.
  • To be able to present information in an appropriate academic format.
  • To understand and demonstrate academic integrity.

One thing to note about the aims and objectives is that they are very much about what skills the student is going to develop and what they are expected to do. The job of the supervisor is to give advice and encouragement when needed. The supervisor may meet with the student for 4 of the 40 hours, but most of the time the student is alone. This is deliberate: the student should show initiative and experience what it is like to work independently on a big project. If the supervisor gets too involved then the aims will not be met.

Go Physics Go

Extended essay.

The IB physics extended essay is all about showing the IBO that you know how to write a research paper.

You need to choose a research question which is interesting enough to you which will motivate you to read research papers on it.

The extended essay needs many resources in the bibliography. Six would be a minimum number. Aim for double digits.

The IB physics internal assessment may have only one independent variable with one five by five table but the extended essay may have two or more independent variables with two or more five by five tables. In other words you may conduct more labs and obtain more data when completing a physics extended essay than a physics internal assessment.

Ask your teacher for samples of the extended essay. If he/she can’t provide any for you then go online and try to find some. If that doesn’t work then e-mail me at [email protected] and I can send you a few.
