Sat / act prep online guides and tips, 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.)

CHEMISTRY EXTENDED ESSAY

These subject guidelines should be read in conjunction with the IB extended essay general guidelines.

Introduction

An extended essay in chemistry provides a candidate with an opportunity to investigate personally a particular aspect of the materials of our environment. Such extended essays must be characterized by a particular chemical emphasis within a more general set of scientific criteria.

Choice of Topic

It is important that the extended essay has a clear chemical emphasis and is not more closely related to another subject. Chemistry is the science that deals with the composition, characterization, and transformation of substances. A chemistry extended essay should therefore incorporate chemical principles and theory, and emphasize the essential nature of chemistry, relating to the study of matter and of the changes it undergoes. Although similar criteria apply to all extended essays in the experimental sciences, for an extended essay submitted in chemistry the topic chosen must allow an approach which distinctly involves chemistry. Where a topic might be approached from different viewpoints, the treatment of the material must be approached from a chemical perspective.

An extended essay in an interdisciplinary area such as biochemistry will, if registered as a chemistry extended essay, be judged on its chemical content, not its biological content. The scope of the topic and the research associated with it should enable all the criteria, particularly the subject specific criteria, to be addressed. A good topic is one where the single research question is sharply focused and is susceptible to effective treatment within the word limit. Perhaps the most important factor is the depth of treatment that can be given to the topic by the candidate.

Some topics may be unsuitable for investigation because of safety issues. For example, experiments involving toxic or dangerous chemicals, carcinogenic substances or radioactive materials should be avoided unless adequate safety apparatus and qualified supervision is available.

Other topics may be unsuitable because the outcome is already well known and documented in standard text books and the candidate may not be able to show any personal input. An example might be a study of the reactions of the alkali metals with water as this is already covered by the syllabus. However some care does need to be exercised in deciding whether a topic is suitable or not; for example, a few years ago the study of the allotropes of carbon may have been thought to be trivial but this would not be the case today.

The following examples of titles for chemistry extended essays are intended for guidance only. The pairings illustrate that focused topics (indicated by the first title) should be encouraged rather than broad topics (indicated by the second title).

"Spectrophotometric determination of trace amounts of lead in drinking water" is better than "Water analysis".
"The kinetics of oxidation of iodine ions with hydrogen peroxide in acidic solutions" is better than "Chemical kinetics".
"The analysis of the red dyes present in different brands of tomato ketchup by thin layer chromatography" is better than "The use of chromatography to separate materials".
"Is it better to use dried animal manure as a fertilizer or as a fuel?" is better than "Combustion and nitrogen analysis".
"The effects of sugar-free chewing gum on the pH in the mouth after a meal" is better than "Acid-base chemistry".

How to Write a Chemistry Extended Essay? IB Guide

The Chemistry extended essay is a blend of scientific research and academic writing.

Luke MacQuoid

Ah, the thrill of the IB program! I remember when I first faced the daunting task of writing my extended essay in Chemistry . Having been through the wringer, I now have a few insights that can help budding IB students like yourself.

Introduction to Chemistry Extended Essay

The International Baccalaureate (IB) curriculum presents its fair share of challenges, and the Chemistry extended essay stands tall among them. If you’re scratching your head and wondering, “What exactly is this paper?” Allow me, a seasoned IB tutor, to explain.

Here is a list of suggestions for Science Investigations. Please add/amend/extend the list as you see fit. This is essentially a brainstorm ...

Non-coalescing drops [ edit | edit source ]

Some industries will mix liquids by cascading one liquid into another, assuming mixing will be complete. These drops may prevent complete mixing and need to be investigated.

Recent research has shed light on this phenomenon: The fast-moving shiny drops that skid across the surface of soapy water. Detergents play a crucial role – but how does the concentration of detergent affect the drops? What about ‘non-ionic’ detergents? What about a surface of anionic detergents and drops of cationic ones?

Challenges: Making drop-producing apparatus, Researching the chemistry of detergents, Assessing the numbers of drops

Thiosulphate/acid reaction (‘disappearing cross’) [ edit | edit source ]

Chemical engineers wishing to check if turbidity is a useful surrogate measurement for whether a reaction has reached completion.

How does the reaction respond to changes in acid concentration (it is first order for thiosulphate concentration but varies from first to zero order with acid).

How can we assess the amount of oil contamination on beaches? [ edit | edit source ]

Various groups will want to assess oil contamination, and a simple quick method would be appreciated.

The method used solvent extraction. Sand samples were laced with oil and the efficiency of recovery was measured. The sensitivity of the method was also estimated.

Synthesis and isolation of propanoic acid from propan-1-ol. [ edit | edit source ]

Chemical suppliers who want to investigate production of this chemical.

Trialling different methods.

Making biodiesel from waste vegetable oil. [ edit | edit source ]

Motoring enthusiasts who want to make their own environmentally-friendly and cheap fuel.

By using methanol and sodium hydroxide it is possible to make diesel fuel from old chip fat.

Analysing the gases remaining after burning a candle in a gas jar. [ edit | edit source ]

Motor vehicle engineers who want to check the composition of exhaust gases.

CO 2 is easy; it is readily absorbed with NaOH.

O 2 is harder; an oxygen probe is very useful but otherwise oxygen could be absorbed by, for example, the slow reaction of steel wool.

CO is challenging; it will be absorbed by CuCl solution but it is in very low concentrations.

Extraction of caffeine from tea. [ edit | edit source ]

Suppliers or independent analysts want to assess the caffeine content of tea products. Chemical suppliers want to provide pure caffeine to clients.

[1] This method usually involves solvent extraction with a chlorinated alkane (e.g. dichloromethane or 1,1,1,-trichloroethane). With care it is possible to recycle the solvent and avoid health and environmental damage.

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.

Tips on conclusion writing

Science has helped the world to decipher and answer some of the hardest questions about the universe and our bodies as well. Currently, researchers are conducting different studies on various scientific topics, and the expectation is that more knowledge will be generated. However, when asked to write analytical reports, research papers, or lab reports, some scientists find themselves struggling to express their ideas on paper. Chemistry students, for example, help to solve some of the most difficult problems that the world faces today. However, when asked to write a chemistry essay, some students find it difficult to express their thoughts and ideas clearly and in a coherent manner. Chemistry papers need to have a main point or argument or simply be specific in what it is trying to discuss or decipher. Students should hence ensure that their essay is specific and narrow, not as general as some of the others.

Chemistry papers are written for different reasons. Some are written to help explain or expound on a concept, others are written to communicate some results while there are some that are solely written for purposes of explaining the processes involved in research. If written as a research paper, a chemistry essay should articulate and make use of the basic scientific structures and formats of writing chemistry essays. Students should hence be conversant with different scientific formats like APA, MLA, and Harvard mainly for referencing purposes. Scientific papers such as chemistry essays follow specific formats and must be cited unless otherwise stated by the instructor.

Outline for a chemistry essay

Writing a chemistry essay outline is essential because it gifts one with a focused guide to completing the paper. In an outline, writers are expected to include their main point as well as some of the supporting arguments that they will include in the body of their essay. Chemistry essay outlining is similar to what is done in other essays and should hence be an easy task. If, for example, students have been asked to write an essay about the element silicon, the outline for such an essay would be as shown below:

Introduction

Background information about silicon.
Briefly, mention its importance in the mainstream world.
The basic structure of silicon as an element. Some of its attributes should also be included.
The role of silicon in construction and architecture.
The use of silicon in the automobile industry.
Reiterate the role of silicon in society today.
Provide a summary of the main points, for example, the main uses of silicon.
Finalize by mentioning how much silicon is a part of people’s lives today.

Writing an Introduction

Writing a chemistry essay introduction can be challenging regardless of how much research one has done.

Below are some introduction writing tips:

Include factual information in the introduction.
Provide background data regarding the topic under study. Include information that will make the essay comprehensible.
Always look for an angle and be consistent in addressing it.
Have a non-ambiguous thesis statement that is direct and clearly outlines the author’s stance.

Writing a Body

The body of a chemistry paper or essay needs to support the writer’s arguments or provide details of an experiment or an investigation.

Below are some tips to help writers deliver quality papers:

Ensure that each paragraph has a topic sentence. A topic sentence bears the main point or argument presented in a paragraph.
The other sentences should offer support to the topic sentence. Writers should not drift away from the main argument that a paragraph presents.
Consistency throughout the paragraph should be enhanced.
Writers should sufficiently reference their work. In-text citations should always be included throughout the article.
Each paragraph should have five to six sentences like other essays and in these, students should ensure that they exhaustively explain their topic.
Transition words, for example, firstly, secondly, additionally, subsequently, etc. should be used to indicate to the readers that the writer is on a different point.

Writing a Conclusion

How to conclude a chemistry essay is a challenge mainly because chemistry essays do not abide by the same rules for writing conclusions. On many occasions, students are expected to assess their hypothesis and determine its accuracy or draw any conclusions from the data that they gathered. However, if the essay did not involve any investigation or study, one can just include a summary of the main points and then relate the topic to what is happening in society today.

Sources for Essay Choice

Online sources are often preferred by students because they are easily accessible and offer simple and straightforward choices. While it is not against any law or rule to source essays online, teachers often advise students to situate what they learn in class to the activities in society. The latter offers one with choices that are audience friendly and that directly resonate with daily life. It also helps people to apply the knowledge they acquired from class to society’s day-to-day problems. However, if one wants to use online sources, below is a good example of a website that can offer one some credible essay choices.

Finalizing Essay

Students are often advised always to begin with a draft before they write a final copy. Having a draft is important and gifts one with the chance of making changes to their essay whenever they feel the need to. The chemistry essay draft will indeed come in handy and gift students with the chance of revising their work. Revisions are important. Once the essay is completed or the draft is completed, it is always necessary to review it and make any changes or corrections before submitting it. Revision and proofreading are necessary and help to ensure that an essay is consistent in focus and is free of any grammatical errors.

World Studies Extended Essay

World studies was first proposed by the United World College of Mahindra in 2001 and was eventually set up as an extended essay pilot option in 2005. The development of the world studies extended essay pilot has been underpinned by extensive academic research and development. IB staff have worked closely with both teachers in the pilot schools and Harvard Graduate School of Education, Project Zero Interdisciplinary Studies Project, to develop this exciting extended essay option.

A world studies extended essay must focus on a topic of global significance. This encourages the student to reflect on the world today in relation to issues such as the global food crisis, climate change, terrorism, energy security, migration, global health, technology and cultural exchange.

The student should then explore how their chosen issue may be illustrated in a local context or contexts using specific examples of a small scale, local phenomenon; in this way the student is linking the local to the global.

As the approach is interdisciplinary explaining the topic through the lens of more than one discipline, students should develop a clear rationale for taking an interdisciplinary approach, selecting the IB disciplines through which they plan to explore the topic. The process of researching and writing the world studies extended essay develops international-mindedness and specifically the concept of global consciousness. This concept encompasses three distinct strands:

global sensitivity - a sensitivity to local phenomena and experiences as expressions of developments on the planet
global understanding - the capacity to think in flexible and informed ways about issues of global significance
global self - a developing perception of self as a global actor and member of humanity, capable of making a positive contribution to the world.
