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: Definition, Criteria, And Topics  

by  Antony W

October 30, 2023

This is the complete guide on IB Chemistry extended essay.

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

What’s a Chemistry Extended Essay?

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

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

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

What’s the Assessment Criteria for Chemistry EE?

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

Criterion A: Research Question  

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

Criterion B: Introduction

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

Criterion C: Investigation

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

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

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

Criterion D: Knowledge of the Topic

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

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

Criterion E: Reasoned Argument

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

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

Criterion F: Application Analysis & Skill Evaluation

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

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

Criterion G: Language Choice

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

Criterion H: Conclusion

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

Criterion I: Formal Presentation

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

Criterion J: Abstract

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

Criterion K: Holistic Judgement

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

How to Choose IB Chemistry EE Topics

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

1. Pick a Topic Specific to Chemistry

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

2. Your Topic Should Be Very Specific

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

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

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

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

3. Avoid Topics Linked to Health and Safety Concerns

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

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

How Should You Treat Your Chemistry Extended Essay Topic?

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

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

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

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

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

Resources   General 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". Other ideas for topics Treatment of the Topic An extended essay in chemistry may be based on literature, theoretical models or experimental data. Whichever category is chosen the candidate should ensure that sufficient data will be available for evaluation and that the topic can be researched accurately using locally available resources. Candidates who choose to write an extended essay based on literature and/or surveys should ensure that their extended essay clearly shows its chemical basis. Essays written at the level of a newspaper or news magazine article are unlikely to achieve a high mark. Since chemistry is an experimental science, candidates are strongly encouraged to undertake experimental work as part of their research, although this is not compulsory. Any experimental work which does form part of a chemistry extended essay should be described in sufficient detail to allow the work to be repeated by others, and candidates are strongly encouraged to research the literature first. Where possible, they should consult original research using scientific journals, personal communications and, where appropriate, the Internet. Textbooks should never be the only source of information. Data collected from an experiment designed by the candidate is of little value unless it is analysed, using appropriate scientific techniques, evaluated and perhaps compared with appropriate models. It is possible to produce an extended essay in chemistry in which the candidate has used data collected elsewhere as the primary source. In such cases, the element of personal analysis and evaluation is important. In any chemistry extended essay candidates should be able to demonstrate that they understand the theory underlying any experimental work and state any assumptions made. They should show an understanding of the results obtained and be able to interpret them with reference to the research question posed. They should be critical of inadequate experimental design, the limitations of the experimental method and any systematic errors. Candidates should be encouraged to consider unresolved questions in their research, and to suggest new questions and areas for further investigation in their conclusion.

(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.

IB CHEMISTRY: INTERNAL ASSESSMENT & EXTENDED ESSAY II IB IA and EE Independent and Dependent Variables – What to consider In every IA or EE, the decision on which variable to manipulate and which variable that the manipulated variable affects is important.  Typically, it is advisable to have only ONE dependent variable for IA and at least TWO for EE.   The key reason for this difference is the amount of time that one spends in the laboratory – 10 hours for IA and 40 hours for EE.  The big difference in the amount of time spent in the laboratory means two things The independent and dependent variables for IA should be easily measurable. The independent and dependent variables for EE can more complicated and indirect in measurement, but the method of measurement must be verified. Independent Variable There are principally two types of independent variables Type of reagent such as type of acid/base, catalyst/inhibitor etc Reaction condition such as temperature, pH, concentration, light intensity, light wavelength etc. There are students who used other types of independent variables, such as Brands of household product, beverage, food etc Types of food and beverage Some examples are Brands of detergents Types of tea, eg.English breakfast tea, Ceylon tea etc. Types of coffee eg. Arabica coffee, Blue Mountain coffee etc While exploring the difference in types of food and beverage or brands of products may seem like a possible independent variable, we highly discourage it.  The reason is that it will be very challenging to explain the results of the experiment using concepts in Chemistry, thus the “discussion” section of the report will not be substantial. Some independent variables are harder to control, such as the wavelength or intensity of light.  Such independent variables manipulation requires the setup of special units that disallow ambient light interference.  We have helped students design and built such setups for experiments, and are contactable through email or phone for a discussion. Dependent variable In deciding the dependent variable, one has to consider the following Is the independent measurable using existing equipment or using methods doable in the school laboratory? For example, – Temperature using thermometer – Concentration of coloured liquid substances using UV-VIS spectrophotometer or colorimeter – Concentration of certain colourless organic liquid substances using uv-vis spectrometer Some students might vary the type of chemicals used in the experimental study. In this case, the student should check if the chemical(s) is available in the laboratory or permissible (non-hazardous or carcinogenic) in the laboratory.   In some cases, the chemical might not be available in the school laboratory and the cost of the chemical might be beyond the budget allocated to each student.  In such a scenario, it might be possible that the student has to pay for the chemical required.

USA TODAY Sports Indiana Fever finally gets chance to catch breath, time to 'figure it out' with rare break Fever at Washington, 7:30 p.m., Friday; TV: ION INDIANAPOLIS – “You’ll figure it out.” That’s what Grace Berger said to NaLyssa Smith near the end of the Indiana Fever ’s practice Wednesday as the two were set to run a play. The moment encapsulates the start of the Fever’s season. It’s been game after game after game for the Fever, with very limited practice time for the 2-9 team. The Fever played 11 games in the first 20 days of the year, while no other WNBA team played over nine in that span. Tamika Catchings on Caitlin Clark: 'There is a lot of weight on her shoulders.' Because of that, windows for practice time have been few and far between for one of the league’s youngest teams. When Indiana has practiced, it’s mainly been in the form of walkthroughs. For a team adjusting to first-overall pick Caitlin Clark running the show at point guard, there hasn’t been much time to iron out wrinkles. So it makes sense players (like Smith) may not be entirely familiar with the plays. When the Fever retake the floor on the road against the Washington Mystics on Friday, it will have been five days since being beaten down 104-68 against the New York Liberty on Sunday. That’s the longest break this squad has seen between games this season, with the previous longest break being just three days. After having Monday and Tuesday off, Wednesday marked the Fever’s first practice at game speed since training camp. It gave the team a chance to truly work on what’s gone wrong so far this year. “You get to fix all the things that you can’t get right,” coach Christie Sides said. “You can’t get right just watching video, it’s live action. You can’t just walk through things and get better, so just being able to do things live changes the game.” Sides said much of Wednesday’s practice was centered around repairing Indiana’s league-worst defense, specifically in transition. For Clark — who was named WNBA Rookie of the Month on Monday — she was thrilled to be “competing a lot more” in a practice setting.  “I haven’t got to practice with my team much,” Clark said. “That’s really hard, trying to navigate an offense and you haven’t had much practice time together. So I think that’s something we’re just gonna continue to navigate but it’s already improved a lot, and it’s only gonna continue.”  Clark left the Liberty game with an ear injury, but that didn’t limit her from practicing, although she said it’s still “a little hard to hear.” Clark is still gaining chemistry with her teammates, as evidenced by her 5.4 turnovers per game. But this practice time — along with bonding events like a team dinner on Tuesday — could help correct the team’s struggles and lack of synergy. Veteran guard Kelsey Mitchell is focused on getting the Fever back on track slowly but surely. “All you can do is rack up as many reps as you can,” Mitchell said. “You’re not gonna get it all back in a couple days, obviously. But you get your daily deposits and deposit every day, I think in the long run, we’re gonna see the fruits of our labor. That’s the idea.”  The Fever won’t have any more back-to-backs after having two already this year, and they’ll have at least three days between games for the next two weeks. Extended periods of rest and practice should lead to more cohesion on the floor. The difficulty of the Fever’s schedule will also decrease in June. Eight of the Fever’s first 11 games have come against teams currently in the top five of the WNBA standings (Connecticut, New York, Minnesota, Seattle and Las Vegas). The Fever have only two such games for the remaining nine games in June — at Connecticut on June 10 and at Seattle on June 27. If the Fever have seemed out of sorts so far this year, it’s because they haven’t had much time working together. But now, the hellish stretch of scheduling the team had to begin the year is behind them, and there’s an opening for the Fever to show growth.  Good or bad, what the Fever show in the coming weeks will be more indicative of who they are than what occurred to start the year. Organic Chemistry Frontiers Chromium-catalysed selective synthesis of 3-oxo and 3-amino quinolines using β-o-4′ lignin models or α-amino ketones. Chromium-catalyzed annulation of 2-aminoaryl alcohol with phenoxy acetophenone to 3-oxo-quinoline derivatives is reported. Phenoxy acetophenones are employed as β-O-4′ lignin models for this conversion. The efficacy of the process was further extended by producing 3-aminoquinolines using α-amino ketone. Notably, these are hard to prepare using conventional method. The catalyst tolerates numerous functional groups, including hydrogenation-sensitive examples, and is applicable for even problematic α-hydroxyacetophenone as substrate. The process can further be extended to the gram-scale reaction and late-stage functionalization of natural products. Experimental studies suggested that the reaction is a highly coupled cascade reaction, involving dehydrogenation, aldol condensation, C-N bond formation and nitrogen-heterocyclic ring construction.
