International Baccalaureate (IB)

body-notes-notetaking-cc0-pixabay

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

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

IB Extended Essay: Why Should You Trust My Advice?

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

body_ibeescore.png

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

What Is the Extended Essay in the IB Diploma Programme?

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

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

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

The IB Extended Essay must include the following:

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

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

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

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

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

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

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

Here are the topics covered in your viva voce :

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

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

What Should You Write About in Your IB Extended Essay?

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

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

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

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

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

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

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

#1: Write About Something You Enjoy

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

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

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

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

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

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

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

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

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

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

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

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

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

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

body-narrow-crack-stuck-cc0-pixabay

Don't get stuck with a narrow topic!

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

#6: Start Writing Sooner Rather Than Later!

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

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

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

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

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

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

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

How Is the IB Extended Essay Graded?

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

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

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

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

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

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

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

A 10.1%
B 24.4%
C 40.8%
D 22.5%
E 1.4%
N (No Grade Awarded) 0.7%

How Does the Extended Essay Grade Affect Your IB Diploma?

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

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

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

body-theory-of-knowledge

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

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

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

160 Biology Essay Topics

For most science courses, assignments are generally lab-based and rarely require much writing. However, all of that changes in biology courses when detailed essays must be written to highlight a student’s understanding of the subject. These essays are highly technical, with specific comments required to meet the factual nature of the subject.

In addition to meeting the factual requirements needed to complete the assignment, biology essays must also be written in a writing style that is informative and authoritative rather than subjective and personal.

These detailed specifics of writing a biology essay can make completing the writing difficult from the very beginning. Fortunately, we’ve created this guide to help students learn how to write a biology essay. In addition, we’ve also included 160 biology essay topics to help inspire the creative writing process.

How to Write a Biology Essay?

Writing a biology essay starts with choosing a topic. If your teacher has not already assigned a specific topic, then students must choose one that is broad enough to find credible resources and specific enough that the research won’t overtake the writing process.

To select a suitable topic for a biology essay, consider the type of biology class you are taking, the current and previous chapters studied, and the overall context of the course. These factors will help you select a topic that is likely to be relevant to your teacher’s needs and to the passing of your course.

Once students have selected a suitable topic, it’s time to research credible resources that will support the subject. To do this successfully, students need to consider the following:

  • What information is already known about this topic?
  • What topics are related or similar to this topic?
  • Who are credible authors that can explain this topic?
  • What additional sources will provide me with the information needed to complete this assignment successfully?

For example, if you want to write a biology essay on protein synthesis and its regulation at the transcriptional level, research material would include books, articles, and other written works published by credible authors or publishers. While important, this material isn’t the only type of research that should be completed.

Students may also consider consulting medical and biology dictionaries, textbooks, online research databases such as PubMed or Medline, and professional organizations for biologists to find additional sources. Once the research has been completed, it’s time to create the first draft of the biology essay.

Biology Essay Introduction

Starting an essay is always the same. Students should open with a catchy hook statement that introduces an interesting fact, presents a unique perspective, or raises a thought-provoking question.

Once that sentence has been created, students can use the middle part of the introduction to introduce fundamental concepts and provide background details about the topic.

Once that information has been laid out, and the reader knows the necessary details to make the reading interesting and worthwhile, students should move into the final portion of the introduction that answers the question: WHY is this essay important? This question is answered in the form of a thesis statement that details the essay’s overall purpose.

Biology Essay Body Paragraphs

The body paragraphs of your essay will contain the bulk of your research. Be sure that each body paragraph meets the following requirements:

  • One clear idea represented per paragraph or section
  • Examples that back up the point of the paragraph
  • A clear and logical flow between paragraphs with transition words

Make sure that the body paragraphs only contain information pertinent to the subject or topic. Avoid fluff or filler words and phrases that don’t add any substance or value to the writing.

The number of paragraphs in the body may vary depending on the assignment parameters and the essay style. For example, an essay with a 1000 word limit won’t have as many body paragraphs as an essay with a high word count.

Additionally, a compare and contrast essay that examines the similarities and differences between two or more biology concepts may have more body paragraphs than an argumentative essay.

Biology Essay Conclusion

The final section of a biology essay is the conclusion. In this section, students need to summarize the major points of the essay and the overall purpose for writing it. The thesis should also be re-stated to recap what has been learned from the writing.

In addition to these sentences, students should include a final remark about their research and findings. This might be a thought that ties into the intro or another interesting angle that presents a new way of looking at your topic.

Once the conclusion is completed, students should edit and review their work. Make sure that the essay is free of grammar and spelling mistakes before submitting it for grading.

When it comes to choosing a biology essay topic, it is not always as easy as it seems. For students looking for help with writing a biology essay, we have compiled a list of 160 biology essay topics that will hopefully give you some great ideas.

Tips on How to Write a Biology Essay: Learn from the Example of Jellyfish Essay

Tips on How to Write a Biology Essay

How to Write a Biology Essay

In this article, we will guide you on how to write a perfect biology essay from scratch. You’ll find various tips to help you excel in writing your essay and creating a paper worth the highest grades. We also prepared a jellyfish essay example for you, so it can be easier to enhance all the specifics and structure of this kind of paper.

What is Biology Essay

A biology essay is a student-written work where you present arguments and ideas about a particular biological topic. The essay on biology can take different forms like argumentative, cause-and-effect, descriptive, detailed analysis, or ‘how-to’ instruction, depending on the professor’s guidelines and writer’s preferences. 

A descriptive paper can explain a biological subject, while an argumentative one provides evidence to support a point of view. It’s up to you to choose which type is more suitable for the topic you’re writing about. The most common type is a cause-and-effect essay explaining an event’s reasons and consequences. 

How to Craft a Perfect Essay About Biology

Writing is an art form that requires time and effort. But if you prefer someone else to write the paper for you, you can just text the experts, ‘ do my homework for me ,’ and consider it done. 

Here is the step by step instruction to organize the process for desired results. 

How to Craft a Perfect Essay About Biology

Choose Your Biology Essay Topic

To get a good grade:

  • make your paper informative and enjoyable by choosing a topic you wish to explore. 
  • Use a brainstorming technique to generate 30-50 options for biology essay topics and research to create a shortlist. 
  • Keep a notebook to jot down your ideas.

Choose a Question for Research

When writing a biology essay, use a scientific approach by selecting a research question related to your topic. Always avoid overly complex or apparent questions. You can also text our profs ‘ write my research paper ,’ and it can be done in a blink.

Create an Outline

Always have a clear plan when writing biology essays while starting a paper. Use a 5-paragraph structure with an outline to keep your main idea and arguments organized. Use any format that works best for you and adjust as needed. Discard any ideas that don’t fit your research question.

Use a Strong Thesis Statement

The introduction should end with a strong thesis statement synthesizing the overall essay, conveying the research question and your point of view. The paper is ineffective without a clear thesis, as readers may not understand your position.

Use Citation and References

Include a list of references in your academic papers, such as biology essays, to avoid plagiarism and provide data sources. Use the appropriate citation style, like APA or CSE, and consult a guide for requirements.

How to Structure a Biology Essay

Ensure your essay has an attention-grabbing introduction, a detailed body, and a solid conclusion with distinct sections. Use around seven paragraphs for the main body, adjusting as needed for the required word count.

Biology Essay Introduction

In the introduction of your essay about biology, showcase your expertise by providing a brief background of the topic and stating the essay’s objective. For a research paper, explain why the study is relevant. Make sure the reader understands the essence of your subject.

The body section of your essay on biology should focus on supporting and defending your thesis statement. To achieve this, make a list of essential points to cover and address each one step by step. Starting a new paragraph for each point ensures neatness and a continuous flow. 

In conclusion, restate your thesis statement and summarize supporting points to solidify your arguments. Avoid introducing new concepts, and leave a lasting impression on your instructor.

Jellyfish Essay - Example of a Biology Essay About a Fascinating Creature of the Ocean

Jellyfish, also known as jellies, are incredible creatures of the ocean. They’re members of the phylum Cnidaria, including corals and sea anemones. You can find jellyfish in every ocean around the globe, from the surface to the depths of the sea. 

Do you know what shape the jellyfish body has?! It’s one of their most unique features. Their bell-shaped body comprises a soft, jelly-like substance called mesoglea, found between two cellular layers. The outer layer of cells, the epidermis, is thin and flexible, while the inner layer, the gastrodermis, contains the jellyfish’s digestive system. At the bottom of the bell is the mouth, surrounded by tentacles armed with stinging cells called nematocysts. 

The jellyfish tentacles consist of venom-filled sacs, which can be potentially dangerous and life-threatening. Considering the severity of its sting, researchers have gathered information on how to treat it effectively. Use thick clothing, tweezers, sticks, or gloves to alleviate the sting. It’s crucial to avoid touching the sting with bare skin since the venom can cause severe harm. Always dispose of the tool used for removing the sting to prevent re-stinging. 

Jellyfish are creatures that feed on small fish and other tiny marine organisms. They capture their prey using the tentacles and bring it to their mouth. Once the food is inside the jellyfish, it’s broken down by digestive enzymes and absorbed into the gastrovascular cavity. 

An exciting thing about jelly is its life cycle. They go through several stages of development, starting as a tiny, free-swimming larva and then growing into a polyp. The polyp stage is stationary, and the jellyfish attaches itself to a surface using a sticky pad. During this stage, the jellyfish reproduces asexually, creating clones of itself. These clones then break off from the polyp and develop into the familiar bell-shaped body of the adult jellyfish. 

Jellyfish play an essential role in the ocean’s ecosystem too. They’re a food source for many marine creatures, including sea turtles and some fish species. They also help to control the population of tiny marine animals by feeding on them, and their waste products contribute to the nutrient cycle in the ocean.

However, jellyfish populations can sometimes explode and become a nuisance. This phenomenon mostly occurs when their natural predators are eliminated from the ecosystem or when water conditions, like temperature and salinity, are conducive for jellyfish growth. In cases where jellyfish populations reach excessive levels, they can clog fishing nets and interfere with other human activities in the ocean.

Jellyfish really are stunning creatures of the ocean. They’re diverse, with many different species, and are essential to the marine ecosystem. While they can sometimes become a nuisance, they’re vital to the ocean’s food web and nutrient cycle. Studying jellyfish can give us a greater understanding of the complex and interconnected systems that make up our oceans.

Practical Tips for Creating Perfect Academic Papers

Developing writing skills is crucial for your academic success regardless of your major. Check out these tips we provided for improving your writing. But if you aren't fond of writing, you can easily hand it to professionals by saying, ‘ do homework for me .’

Search for Samples or Examples

To improve your writing, analyze examples of well-written biology essays or research papers. Although not all online samples are perfect, they can still provide insights into what works and what doesn’t. However, avoid plagiarism and ensure your paper is original by presenting fresh ideas and a unique perspective. 

Read Whenever You Can

Develop your writing skills by reading widely and extensively. Look for biology papers in scientific journals, websites, or books. Don’t forget to take notes on interesting points that you can use in your papers later.

Practice Makes Perfect

Don’t expect to write a perfect paper on your first try, so take every opportunity to practice your writing. Find a mentor if needed and use online resources to learn from your mistakes and improve your skills.

Always Organize Your Writing Process

Organize your work process instead of waiting for inspiration by defining stages, scheduling time for each task, and eliminating distractions. Don’t wait for mood to write an essay about biology; use different strategies to overcome writer’s block.

Proofread and Get Other Feedback

It’s hard to assess your own work accurately. Seek feedback from peers or instructors to identify strengths and weaknesses to improve upon. Don’t wait for your professor’s feedback to know if your biology essay is good. 

Interesting Biology Essay Topics from Our Experts to Practice Your Writing

In this paragraph, we listed different biology essay topics from which you can choose your preferred one and practice writing to excel in your academic papers.

  • A jellyfish - my favorite creature

Introduction

A Level Biology is a challenging but rewarding course that covers a wide range of topics, from DNA and genetic inheritance to ecosystems and biodiversity. The key to success in this subject lies in understanding and applying the core principles of Biology and expressing your understanding in well-structured, coherent essays. In this article, we will provide you with some essential tips for writing outstanding A Level Biology essays, as well as presenting clear examples to help you master the essay-writing process.

  • Understand the essay question

The first and most important step in writing an A Level Biology essay is to clearly understand the question. Break down the question into its key terms and implications, and ensure you comprehend what the examiner is asking you to discuss. Make a note of any key words or phrases that should feature in your essay, as these will help you structure your response and ensure you cover all the necessary points.

  • Plan your essay

Before you begin writing your essay, take the time to plan your response. Create an outline that maps out the main points you want to make, as well as the order in which you will discuss them. This will enable you to develop a logical and coherent argument that addresses all the key aspects of the question.

  • Include an engaging introduction

An effective introduction is crucial to grabbing the reader’s attention and setting the tone for your essay. Begin with a general statement that links to the essay question, and then narrow down your focus to present your main argument or line of inquiry. Finish your introduction with a clear thesis statement, which outlines the central points you will cover in your essay, demonstrating a solid understanding of the topic.

Example: The discovery of DNA and the subsequent advancements in genetic research have proven instrumental in understanding the role of genetics ininheritance of traits and diseases. This essay will discuss the role of genetic inheritance in the development of several human diseases, namely: Cystic Fibrosis, Huntington’s disease, and Alzheimer’s disease, as well as the ethical implications surrounding genetic testing and treatment.

  • Use specific examples to support your arguments

In A Level Biology essays, it is essential to provide examples that demonstrate your understanding of the material and support your claims. Try to include a range of examples from different areas of the subject to show that you have a comprehensive and in-depth understanding of the course material.

Example: Cystic Fibrosis is an example of a genetic disorder caused by a mutation in the CFTR gene, which results in thick and sticky mucus production in affected individuals. This condition can lead to respiratory and digestive complications, illustrating the significant impact of genetic inheritance on an individual’s health.

  • Synthesize information from multiple sources

To demonstrate a high level of understanding, A Level Biology essays should integrate information from various sources, such as class notes, textbooks, and scientific articles. Be sure to support your ideas with specific references to the source material, and use your own words to explain the concepts in a clear and concise manner.

  • Address counterarguments and controversies

In any scientific field, there are often debates and controversies surrounding key concepts and theories. To show a comprehensive grasp of the subject matter, be sure to address counterarguments and discuss opposing viewpoints in your essay.

Example: While genetic testing for diseases such as Huntington’s has the potential to provide valuable information for individuals at risk, there are ethical concerns about the potential misuse of genetic information by employers, insurance companies, and even government entities. Weighing the benefits of genetic testing and treatment against these ethical concerns is an ongoing debate within the scientific community.

  • Write a strong conclusion

To wrap up your essay, restate your main argument and summarize the key points you have made. Provide a clear and concise conclusion that demonstrates the significance of your argument and its implications for the broader field of Biology.

Example: In conclusion, the role of genetic inheritance in human diseases, as illustrated by Cystic Fibrosis, Huntington’s disease, and Alzheimer’s disease, underscores the immense potential of genetic research to improve our understanding of human health. However, as we continue to advance our knowledge and develop new treatments and testing methods, it is crucial that we remain conscious of the ethical implications that come with such advancements in order to protect individuals’ rights and liberties.

  • Proofread and edit your essay

Finally, make sure you thoroughly proofread and edit your essay to correct any grammar, spelling, or punctuation errors, and to ensure that your argument flows smoothly and logically. Consider asking a friend or peer to review your essay and provide feedback – a fresh perspective can help you identify areas for improvement that you may have overlooked.

In summary, mastering A Level Biology essays involves understanding the essay question, planning a clear and logical response, using specific examples and evidence, synthesizing information from multiple sources, addressing counterarguments and controversies, and crafting a compelling introduction and conclusion. By following these steps and using the examples provided, you will be well on your way to delivering high-quality, insightful essays that demonstrate an excellent understanding of the complex and fascinating world of Biology.

Good luck, and happy essay writing!
