IB Extended Essay Topics: Physics

Stepping into the International Baccalaureate (IB) Diploma program is a significant milestone, and choosing the right Extended Essay topic in Physics can be exciting and daunting. From my years of experience as an IB educator and essay advisor, I’ve seen firsthand how the choice of topic can affect a student’s research. Therefore, in this article, I aim to share insights and ideas on topics for the IB DP Physics Extended Essay.

Understanding the IB Physics Extended Essay

The IB Physics Extended Essay is an independent, self-directed piece of research that culminates in a 4,000-word paper required for the International Baccalaureate Diploma Programme.

According to the IB criteria, this significant academic task involves students independently researching a topic that sparks their interest in IB DP Physics. It’s an excellent opportunity to investigate a question that captivates you and apply theoretical concepts to practical situations.

The primary aim is not merely to produce an essay but to engage in an exhaustive study showcasing your grasp of physics and enthusiasm for the subject. Now, let’s consider the following aspects of the IB Physics Extended Essay:

• Scope of Research . It’s essential to select a topic that allows for an in-depth investigation within the constraints of the available resources and the word limit.
• Application of Theory . The essay should demonstrate how physics theories and concepts can be applied to analyze a specific problem or question.
• Methodology . A clear and systematic approach to conducting your research is critical. It involves choosing appropriate methods for data collection and analysis.
• Critical Thinking . Throughout your essay, you should critically evaluate the information, data, and methodologies used.
• Creativity and Originality . Finding innovative ways to approach your topic can set your essay apart. It’s about posing new questions, exploring novel perspectives, or applying theories in unique contexts.
• Structured Argument . Your essay should present a coherent argument supported by evidence, leading the reader through your findings to a logical conclusion.
• Reflection . Reflecting on what you have learned from the research process and how it has affected your understanding of the subject area is a valuable component of the essay.

Remember, the goal is not just to write an essay but to engage in a thorough investigation demonstrating your understanding and passion for the Physics course.

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?

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.)

IB Extended Essay Ideas

What’s covered:, what is the ib extended essay, extended essay examples, how is the ee scored, how does the extended essay affect my admission chances.

The International Baccalaureate Diploma Programme (IBDP or IB) is a rigorous high school program considered to be equivalent to the AP system, if not harder. Along with coursework and examinations in this two-year long program, there are expectations to write an in-depth essay on one subject of your selection, called the Extended Essay (EE). The following article is about the EE and presents ideas for topics to write about. 

The EE is an essay required to gain the IBDP and pass the course. It’s not like any regular essay, as it gives the student a chance to write a college-level research paper at an earlier point of their lives, giving them useful exposure for their future endeavors in further education. The essay is written in a single subject of your choosing, giving you six options to choose from. The EE is usually done in one of your HL classes, as it could have more scope to produce a more in-depth paper based on the increased amounts of coursework available in HL. 

The essay is expected to be around 4,000 words long, making it not only lengthy to read but time-intensive to produce. This means students must usually figure out which subject they’re writing for early, to give them time to start earlier. The process of planning a draft, along with your appointed EE supervisor, can take up most of your time in the first year of IB (11th grade). It’s common to not start the actual writing until our 2nd year, where you not only have learned enough coursework for the subject, but have also drafted enough to create a well-written essay. 

Choosing a topic for the EE can be difficult, but hopefully the ideas and examples in this article can give you some inspiration to create your own. 

Given there are 6 subject groups in IB, each with numerous options for those groups it would be nearly impossible to suggest examples for each subject, instead we will show examples for popular subjects. These examples can serve as blueprints for crafting your own ideas! 

Example EE Topic 1 – Math HL

Example Topic: Practical Applications and Implementations of the Golden Ratio

This irrational number is often represented visually as such: 

This image contains fibonacci vectors, a visual representation of the golden ratio. It’s an interesting concept because it’s a shape/ratio that our brains are seemingly wired to prefer things to take form in, a subconscious level of attraction. Many architects and artists today use this ratio to produce visually appealing works of art, but what other practical applications have risen from this mathematical concept? An EE would be a great way to learn more about this and present it in an interesting manner! 

Example EE Topic 2 – Physics SL

Topic: Build Your Own Radio

This topic requires some fundamental understanding of circuitry and electronics, a big component of physics SL and HL. Building a radio requires thorough understanding of currents, resistances and circuit design aspects that are usually best understood through practical, hands-on learning. 

This project could also demonstrate your knowledge in waves, specifically radio and microwaves required to operate the radio. If documented right throughout the whole process, this could make for not only a very extensive and interesting EE, but fun as well! 

Example EE Topic 3 – English SL/HL

Topic: The Effects Of Shakespearean Literature On Modern English

English EE topics are a bit more difficult than other subjects because it may be the least objective class to write about. That being said, it can also be the most creative EE to write for, with this topic being an ideal example. 

Shakespeare contributed lots to literature and writing, especially in the form of plays and dramas, but how can these be observed in modern day literature? Focus on how forms of comedy from Shakespeare’s plays are implemented in modern comedy, or how some forms of artistic expression from that era could be considered problematic today. 

To make this better suited for HL, try going more in depth about other forms of literature that draw from Shakespearean influence, and more specific implementations of humor, such as slapstick (just an example of many). 

Talk about how literature personally influences you, because this EE is an opportunity to not only present information through research, but to also indulge the reader about yourself and your personality! 

IB scores the EE out of 34 points, with 5 letter grades being assigned as boundaries:

EE and Theory of Knowledge (TOK) are graded together along with CAS, to form the “core” of IB which is worth a total of 3 out of 45 points. The following table details this:

The EE doesn’t have much direct influence on your chances of admission, but learning how to write a great essay through the EE can. The admissions process requires writing a great quality essay to showcase yourself to the office of admissions as best as you can. The EE not only teaches you how to write an informative essay, but a high quality one as well! More factors are also responsible for your chances of admission, and for more info on this check out CollegeVine’s admissions calculator !

What is the IB Extended Essay?

The Extended Essay , along with the Creativity, Activity, Service component and Theory of Knowledge , forms an integral part of the IB Diploma Programme . It offers IB high school students an opportunity to explore a topic of personal interest in-depth, develop research and writing skills, and experience the rigours of academic investigation.

One of the distinguishing features of the IB Extended Essay is its length. It requires students to write a substantial essay of up to 4,000 words, which is equivalent to about 16-20 pages. This allows students to delve into their chosen subject matter and demonstrate their ability to engage with complex ideas.

Over 88,000 IBDP students across the globe undertook the Extended Essay in 2022 as part of their IB Diploma requirements. It has been lauded as an effective preparation for university-level research and writing, helping students develop critical thinking, analytical, and independent research skills.

The Extended Essay is an opportunity for students to apply the knowledge and skills gained from their chosen subjects in a multidisciplinary manner. It encourages interdisciplinary exploration, enabling students to connect different areas of knowledge and develop a deeper understanding of the subject matter.

In order to successfully complete the Extended Essay, students must adhere to a structured process that includes selecting a research question, conducting thorough research, organising their findings, and presenting their analysis and conclusions in a coherent manner. By undertaking the IB Extended Essay, students not only enhance their academic skills but also develop essential skills such as time management, critical thinking, and independent inquiry.

How to Choose Your Extended Essay Research Question?

Choosing a research question for your IB Extended Essay is a crucial step that sets the direction and scope of your investigation. Here are some key considerations to keep in mind when selecting your research question:

1. Personal Interest: Choose a topic that genuinely interests you. Passion for the subject matter will fuel your motivation and dedication throughout the research process.

2. Feasibility: Ensure that your research question is manageable within the constraints of the Extended Essay. Consider the availability of resources, time required for research and analysis, and the scope of the topic.

3. Specificity: Formulate a research question that is focused and specific. A broad question may lead to a lack of depth in your analysis, while a narrow question may limit the availability of relevant sources and data.

4. Relevance: Select a research question that is relevant to the subject you are investigating. It should align with the objectives and content of the chosen subject area.

5. Novelty: Aim for a research question that offers a unique perspective or contributes to existing knowledge. Originality in your approach and analysis can make your Extended Essay stand out.

6. Consultation: Seek guidance from your teachers, mentors, or IB tutors . They can provide valuable insights and help you refine your research question.

Remember that your research question will shape the entire trajectory of your Extended Essay, so take the time to carefully consider and refine it before proceeding with your research.

Now, let's explore a variety of ideas for each subject, providing you with a diverse range of potential topics to consider for your IB Extended Essay.

Formatting and Structure Guidelines for the IB Extended Essay

To ensure a well-organised and coherent IB Extended Essay, consider the following structure as a guideline:

1. Title Page : Include essential information such as the title, subject, research question, and candidate number. Refer to the official IB Extended Essay Guide for specific requirements.

3. Table of Contents : Create a clear and accurate table of contents that outlines the structure of your essay, including sections, subheadings, and page numbers.

4. Introduction : Start with an engaging introduction that presents the research question, provides background information, and explains the significance of the topic. Clearly state the aim and objectives of your research.

5. Body : The body of your essay should delve into your research in-depth. Organize your content into coherent paragraphs, each addressing a specific aspect of your research. Consider the following elements:

a. Literature Review: Provide an overview of the relevant literature and theories related to your research topic. Analyse existing research, highlight key concepts, and discuss any debates or gaps in knowledge.

b. Methodology: Describe the research methodology employed, including the research design, data collection methods, and ethical considerations. Explain why the chosen methods are appropriate for addressing your research question.

8. Appendices (if applicable): Include any supplementary materials, such as raw data, charts, graphs, or additional supporting evidence that are relevant to your research.

Typically, the Extended Essay has a word limit of around 4,000 words. It is important to note that this word count does not include footnotes, citations, and the bibliography. Additionally, the essay should be formatted using a standard font (e.g., Times New Roman or Arial) and a font size of 12 points. It is recommended to have double-spacing throughout the essay and to include page numbers.

The IB Extended Essay Assessment Criteria and Grading

The IB Extended Essay is assessed by examiners appointed by the IB on a scale of 0 to 34. Your essay will be evaluated based on five criteria, each carrying a specific point value. It is crucial to comprehend these criteria and how they relate to letter grades to gauge your performance accurately. Here's an overview of the assessment criteria:

Criterion A: Focus and Method (6 points maximum) Demonstrate a clear research question and a well-defined approach. Show how you applied appropriate research methods to investigate your topic.

Criterion B: Knowledge and Understanding (6 points maximum) Display a strong understanding of the subject matter, relevant concepts, and theories. Support your arguments with accurate and relevant evidence.

Criterion C: Critical Thinking (12 points maximum) Apply critical thinking skills to analyse and evaluate information, theories, and arguments. Demonstrate the ability to consider alternative viewpoints and draw well-reasoned conclusions.

Criterion D: Presentation (4 points maximum) Organize your essay effectively with a clear and logical structure. Use proper formatting, referencing, and citation methods consistently.

Criterion E: Engagement (6 points maximum) Engage in a reflective process throughout your research and writing. Show awareness of the strengths, limitations, and implications of your research.

To determine your letter grade, it is important to understand how the rubric assessment points correlate to the overall score. Here is a rough estimation of how the point values align with letter grades:

• 30-34: Excellent - A
• 25-29: Good - B
• 17-24: Satisfactory - C
• 9-16: Mediocre - D
• 0-8: Elementary - E

However, relying solely on these point values is not sufficient. It is crucial to thoroughly read and comprehend the specific grade descriptors provided by the IB. These descriptors offer comprehensive information about the expectations and criteria that examiners consider when assigning letter grades.

The grade you receive on your IB Extended Essay contributes to your overall International Baccalaureate Diploma Programme points score. The Extended Essay and Theory of Knowledge combined are worth up to 3 points of the total 45 points available for the IBDP .

Is the IB Extended Essay hard?

The IB Extended Essay is undoubtedly a challenging undertaking, requiring significant effort and dedication, and is one of the hardest IB subjects . It is estimated that between 70% and 80% of IB students successfully complete the Extended Essay each year. Less than 14% of students received an A in the extended essay in 2022, showing its difficult.

Can you change your research question after starting the Extended Essay?

Yes, it is possible to change your research question after starting the Extended Essay. However, it is important to consult with your supervisor and ensure that the new research question still meets the requirements and aligns with the subject area you are pursuing.

When is the deadline to submit the Extended Essay?

The deadline to submit the Extended Essay can vary depending on the policies and timelines set by individual schools. In most cases, schools establish internal deadlines to ensure students have ample time to complete and revise their essays before the final submission. The typical deadline for submitting the Extended Essay is often set in the first half of the senior year, ranging from November to January.

Can you collaborate with other students on the Extended Essay?

• Extended Essay

Some sections of this website are strictly teacher only however this part is for students. I have tried to use both my experience writing an essay and as a supervisor to give some advice to students thinking of writing a physics EE.

For the student the early days of the EE are full of choices, firstly which subject to choose, secondly which topic and thirdly what research question. There are many reasons that students choose to write their EE in physics:

• Physics is their best/favourite subject.
• They want to study physics at university.
• They want me to write a teacher recommendation.
• They find physics difficult and think this might improve their chances.

These are all valid reasons, in fact I often say to students that if they want me to write a teacher recommendation for them then they might consider doing an EE in physics, it means that I can really add some meat to the reference. It makes a big difference when you can write about the independent research that the student is involved with and all the challenges they have faced, universities are often more impressed than the IB examiners.  

Students don't have to be good at physics to write a good essay as long as they stick to what they know, its probably easier to score well for a student who is a good essay writer and poor at physics than someone who is good at physics but can't write an essay. From the beginning it must be stressed that this is an essay not a university research paper so doesn't have to be cutting edge, as you will find out most of the marks of for how the essay is structured not the physics. This is a problem for some of our student who maybe like physics because they don't like writing essays, if that is the case then I am afraid that they will not get a good grade writing an essay in any subject so they might as well do it in physics and add their weight to the dreadful statistics.

If you are new to the IB then you might not know this yet but to get an A with a physics extended essay is almost impossible, the statistics are certainly not encouraging.

Since this is about writing an extended essay I should quote the source of these numbers

http://occ.ibo.org/ibis/documents/dp/d_x_dpyyy_stb_0905_1_e.pdf http://occ.ibo.org/ibis/documents/dp/d_x_dpyyy_stb_0811_1_e.pdf http://occ.ibo.org/ibis/documents/dp/d_x_dpyyy_stb_0805_1_e.pdf

These are the IB Diploma Statistical Bulletins for the relevant years, they contain a lot of other interesting statistics if you are interested in that sort of thing.

What these figures show is that less students get grade A's in group 4 subjects than the others. It does not say that it is more difficult to get an A in a group 4 subject but that's how a lot of people interpret it.

Type of Essay

There are 5 types of essay

• Experimental: design and implementation of an experiment, then personal collection and analysis of the data.
• Data-based : location and extraction of raw or processed data, not collected directly by the student, which is then further refined and analysed.
• Theoretical : development of a quantitative or semi-quantitative description of some physical phenomenon, exercise of the model, predictions about its behaviour and limitations.
• Survey: formulation of a cohesive, ordered, analytical and supported (qualitative and quantitative) discussion of the topic.
• Combination : some combination of the approaches listed above.

Whichever one of these is chosen it is important that the student has the possibility to put some of their own ideas into the essay, these don't have to be correct but if not they must have enough understanding to realise why they are not. It's far easier to have personal input when doing an experimental type essay so these are the type that i promote with my students and what this website will focus on.

Physics Extended Essay Topics

Luke MacQuoid

The Physics Extended Essay is a research paper required for students in the International Baccalaureate (IB) Diploma Programme who are studying physics. The Extended Essay is an independent analysis project that allows students to explore a specific topic of interest in depth.

The Extended Essay in physics allows students to engage in scientific research, following the scientific methods and conventions, to discover, demonstrate and communicate their understanding of the natural world. Through this process, students develop research skills, critical thinking abilities, and the ability to effectively communicate their findings through writing.

The Physics Extended Essay is a requirement for students who are aiming to complete the IB Diploma and should be a scientific investigation of approximately 4,000 words that explores a specific topic related to physics. The topics can vary widely and can be experimental, theoretical, or historical. The student should be able to develop a clear research question, hypothesis, and methodology and should have a detailed plan for carrying out the investigation. The student should also be able to analyze the data and draw a conclusion based on the research findings.

It’s important to keep in mind that it is important for the EE topic to be researchable, and the research question should be in line with the IB subject guide, this is to ensure that the research is to the level that is expected of the diploma students.

Students can use these extended essay topics in physics  as a starting point for their own research. The key is to select a topic that is of interest to the student, and that can be researched within the scope and guidelines of the IB Diploma Programme.

Once a topic has been selected, students can start by researching the topic using various sources such as academic journals, books, and online resources. They should also consult with their supervisor, who can provide guidance and feedback on their research plan.

For these physics topics, the student can start by formulating a research question that is specific, measurable, attainable, relevant, and time-bound (SMART) and aligning it with the subject guide. They should then develop a research plan that includes a hypothesis, method, and list of equipment or materials required for the experimentation. The student should also make sure that their research plan is ethical and considerate of any potential risks.

The student can then conduct the research , taking careful and accurate measurements and recording their results. After collecting data, students can then analyze their findings and draw conclusions.

Finally, students should use the results of their research to write their extended essay, which should include an introduction, methodology, results, discussion, and conclusion. It should be written in a clear and concise manner, following the guidelines and format established by the International Baccalaureate organization. The essay should also include a bibliography listing all sources used in the research process.

Throughout the process, students should keep in mind that the supervisor is there to help and should be consulted regularly to ensure that the research is on track and that any issues are addressed in a timely manner.

In conclusion

The Extended Essay is an important aspect of the International Baccalaureate (IB) Diploma Programme. It provides students an opportunity to conduct independent research and develop critical thinking skills. In this response, I’ve suggested several physics topics that students could use as a starting point for their EE. 

It’s important to select a topic that is of interest to the student and that can be researched within the guidelines and scope of the IB program. Students should also consult with their supervisor to ensure that their research question is SMART, ethical, and in line with the subject guide. They should also develop a research plan and conduct their research carefully and accurately, analyzing the data and drawing conclusions.

Finally, students should use their research to write a clear and concise extended essay that adheres to the guidelines and format established by the IB organization. They should also include a bibliography and list all the sources used in the research process.

Writing an extended essay can be challenging, and students may need additional help to ensure they write a successful essay. To overcome this, a student may seek help from an essay writing service , which can provide professional guidance and support throughout the research and writing process.

And one problem students face here is gathering ideas for their IB extended essay. Here is some guiding information that can help with extended essay topics.

⏭ ORDER CUSTOM EXTENDED ESSAY ⏮

The first and the most important thing is to come up with an idea for it. When people come up with the right idea for it, they can work hard and make their way through this. The same with IA and EE – a good extended essay can only be written when the right topic is selected. If you do not select the right topic you want to focus on, the chances of failing your extended essay are way higher.

Once the topic is selected, further information can be gathered on it. However, the prompt that you are working o n should be one that you are very well aware of. Not just that, but you should also be extremely interested in the topic. Only then can you work very well on this topic.

IB Extended Essay Layout

There are mainly six elements in the essay layout. The first part is the title page. Here, the research question is written, along with the subject and the category. The total word count needs to also be mentioned here. The next part is the content page. This is the one that is right at the beginning. It has all the headings along with the page numbers as well.

Then, next comes the introduction. Here, the scope and focus of the research is written. Alongside that, the sources that are used and the main argument that is going to be presented is also written. Next comes the main part of the essay, which is the body of the essay. This is the part where the research and the analysis s done. The evaluation also comes here, where the student is supposed to give his own viewpoint here. The argument should be developed in a coherent fashion here. Everything should be in the right order as well here.

Meanwhile, if you are interested in writing IB extended essay, please check the article that describes in detail how long it takes to write an IB EE . And never forget that an extended essay should be up to 4000 words , around 14-15 pages of content.

After this is done, the conclusion part comes. Here, the argument is summarized. Not just that, but any limitations of the research and also any unsolved issues are highlighted here. Towards the end comes the bibliography of the essay. Once the student chooses the academic style of references, the references are written in the correct order.

Other sections that can be added in the essay include the methodology and the appendix. The appendix is where the extra material is written. The methodology is where the entire part of the essay that describes the way that information is gathered. According to the latest requirements , no abstract is needed.

Physics EE - Electricity/Waves/Fields&Forces

Recommended Posts

Hello, this is my first time posting in here! I need some help with my EE.

My topic is still due in 3 weeks, but i need assistance. I wanted to do it on Theoretical Physics, but my teacher said that it would get a low grade, so that's out of the matter. Then, i told her if i could do something related to levitation (Superconductivity), but she told me that it was too complex and it wasn't recommended, also, a superconductor was expensive and difficult to make. After that, i ran out of ideas, and i would like to do my topic on something related to Electricity/Fields and Forces or Waves, as they are the topics that i'm the most interested in. I've tried looking in past Physics papers, but then my teacher told me that my EE had to be original.

I know this might not be what you're looking for, but have you considered doing an EE in a different subject? I know physics EE's are pretty complicated and difficult to score well in.

My Geography teacher already has two guys doing their EE's on Geo, and i suck at Literature.

What are you other subjects? Perhaps a humanities EE?

Well, I am not sure if you can do this experiment or not. But I was wondering about temperature on electrical devices.

For example semiconductor diode.

The question is how will the temperature affect the output of the semiconductor diode?

Firstly you should check with your teacher if you can do this. Because I am not sure if it is in the syllabus or not.

For this experiment you will need a diode and a voltmeter to measure the output. Also You need a heating device to change the temperature of the diode or maybe water. If possible. Well not sure if you can have the device and how will you control it. To moderate the temp a thermocouple will be useful.

I will leave the rest for you to figure. But I will think of another idea and will get to you soon.

another Idea but not sure if it is good. It is related to temp and electricity too

1- Comparison between fibre optic cable and copper. Which will be affected by the change in temp

That looks pretty interesting. Does the topic have to be necessary in the syllabus?

I am willing to learn AHL topics and such.

No they must not be in the syllabus. Thats what my teacher said to me when I proposed to him my idea.

I think these are no in the syllabus so hopefully you can use them.

Also I got one about waves. How does the change temperature of water would affect its wave? You can relate it to the Viscosity of water.

Would the temperature affect the Viscosity and thus affect the water waves. Would the frequency increase or decrease. Is there a change in wavelength or amplitude. extra..

You can look it from different views

Any more ideas? I've tried to do this topic, i don't know if it's suitable:

To what extent does the resistivity of a cable affects the pendulum kinematics when an electrical current is applied?
