What Is a Science Essay?

A science essay is an academic paper focusing on a scientific topic from physics, chemistry, biology, or any other scientific field.

Science essays are mostly expository. That is, they require you to explain your chosen topic in detail. However, they can also be descriptive and exploratory.

A descriptive science essay aims to describe a certain scientific phenomenon according to established knowledge.

On the other hand, the exploratory science essay requires you to go beyond the current theories and explore new interpretations.

So before you set out to write your essay, always check out the instructions given by your instructor. Whether a science essay is expository or exploratory must be clear from the start. Or, if you face any difficulty, you can take help from a science essay writer as well. 

Moreover, check out this video to understand scientific writing in detail.

Now that you know what it is, let's look at the steps you need to take to write a science essay.

How To Write a Science Essay?

Writing a science essay is not as complex as it may seem. All you need to do is follow the right steps to create an impressive piece of work that meets the assigned criteria.

Here's what you need to do:

Choose Your Topic

A good topic forms the foundation for an engaging and well-written essay. Therefore, you should ensure that you pick something interesting or relevant to your field of study. 

To choose a good topic, you can brainstorm ideas relating to the subject matter. You may also find inspiration from other science essays or articles about the same topic.

Conduct Research

Once you have chosen your topic, start researching it thoroughly to develop a strong argument or discussion in your essay. 

Make sure you use reliable sources and cite them properly . You should also make notes while conducting your research so that you can reference them easily when writing the essay. Or, you can get expert assistance from an essay writing service to manage your citations. 

Create an Outline

A good essay outline helps to organize the ideas in your paper. It serves as a guide throughout the writing process and ensures you don’t miss out on important points.

An outline makes it easier to write a well-structured paper that flows logically. It should be detailed enough to guide you through the entire writing process.

However, your outline should be flexible, and it's sometimes better to change it along the way to improve your structure.

Start Writing

Once you have a good outline, start writing the essay by following your plan.

The first step in writing any essay is to draft it. This means putting your thoughts down on paper in a rough form without worrying about grammar or spelling mistakes.

So begin your essay by introducing the topic, then carefully explain it using evidence and examples to support your argument.

Don't worry if your first draft isn't perfect - it's just the starting point!

Proofread & Edit

After finishing your first draft, take time to proofread and edit it for grammar and spelling mistakes.

Proofreading is the process of checking for grammatical mistakes. It should be done after you have finished writing your essay.

Editing, on the other hand, involves reviewing the structure and organization of your essay and its content. It should be done before you submit your final work.

Both proofreading and editing are essential for producing a high-quality essay. Make sure to give yourself enough time to do them properly!

After revising the essay, you should format it according to the guidelines given by your instructor. This could involve using a specific font size, page margins, or citation style.

Most science essays are written in Times New Roman font with 12-point size and double spacing. The margins should be 1 inch on all sides, and the text should be justified.

In addition, you must cite your sources properly using a recognized citation style such as APA , Chicago , or Harvard . Make sure to follow the guidelines closely so that your essay looks professional.

Following these steps will help you create an informative and well-structured science essay that meets the given criteria.

How to Structure a Science Essay?

A basic science essay structure includes an introduction, body, and conclusion. 

Let's look at each of these briefly.

• Introduction

Your essay introduction should introduce your topic and provide a brief overview of what you will discuss in the essay. It should also state your thesis or main argument.

For instance, a thesis statement for a science essay could be, 

"The human body is capable of incredible feats, as evidenced by the many athletes who have competed in the Olympic games."

The body of your essay will contain the bulk of your argument or discussion. It should be divided into paragraphs, each discussing a different point.

For instance, imagine you were writing about sports and the human body. 

Your first paragraph can discuss the physical capabilities of the human body. 

The second paragraph may be about the physical benefits of competing in sports. 

Similarly, in the third paragraph, you can present one or two case studies of specific athletes to support your point. 

Once you have explained all your points in the body, it’s time to conclude the essay.

Your essay conclusion should summarize the main points of your essay and leave the reader with a sense of closure.

In the conclusion, you reiterate your thesis and sum up your arguments. You can also suggest implications or potential applications of the ideas discussed in the essay. 

By following this structure, you will create a well-organized essay.

Check out a few example essays to see this structure in practice.

Understanding Science

How science REALLY works...

• Understanding Science 101
• Misconceptions

Misconception: Science is a collection of facts.

Correction: Science is both a body of knowledge and the process for building that knowledge. Read more about it.

What is science?

The word “ science ” probably brings to mind many different pictures: a fat textbook, white lab coats and microscopes, an astronomer peering through a telescope, a naturalist in the rainforest, Einstein’s equations scribbled on a chalkboard, the launch of the space shuttle, bubbling beakers …. All of those images reflect some aspect of science. But none of them provides a full picture because science has so many facets:

• Science is both a body of knowledge and a process. In school, science may sometimes seem like a collection of isolated and static  facts listed in a textbook, but that’s only a small part of the story. Just as importantly, science is also a process of discovery that allows us to link isolated facts into coherent and comprehensive understandings of the natural world .
• Science is exciting. Science is a way of discovering what’s in the universe and how those things work today, how they worked in the past, and how they are likely to work in the future. Scientists are motivated by the thrill of seeing or figuring out something that no one has before.
• Science is useful. The knowledge generated by science is powerful and reliable. It can be used to develop new technologies , treat diseases, and deal with many other sorts of problems.
• Science is ongoing. Science is continually refining and expanding our knowledge of the universe, and as it does, it leads to new questions for future investigation. Science will never be “finished.”
• Science is a global human endeavor. People all over the world participate in the process of science. And you can too!

What is science—and why does it matter?

by Chris Woodford . Last updated: January 4, 2022.

Q uestions, questions. Why this...? Why that...? How does this...? How come that...? If you're the sort of person who's always seeking answers, maybe you're a scientist of sorts without knowing it? Knowing , in fact, is what science is all about: the term "science" is linked to Latin words like scire ("to know") and scientia ("knowledge"), so it's the process of finding answers to how and why the world works as it does. From why the sky's blue to how your nose smells, from why boats float on water to what makes us happy or sad , you can seek answers—and enlightenment— in all kinds of ways: you can ask your friends their opinion, pray to a god, paint pictures, write songs, or meditate on a mountain, scratching your head. What makes science so different from these other ways of thinking about things—and why does it matter?

What is science?

What makes science different is that it's a very systematic way of building up knowledge. It uses logical thinking to explain why things work or how things happen based on evidence gathered through observation and experiment. Slowly and surely, science comes up with coherent explanations called theories that mesh with bigger theories to make ever more comprehensive accounts of what's going on around us. So, for example, Isaac Newton's comprehensive, "universal" theory of gravity was built on smaller theories like Galileo's observations of how falling objects hurtle toward Earth and Johannes Kepler's ideas about the planets sweeping through space, themselves based on earlier science dating back to ancient times. Newton's ideas, in turn, became part of a wider explanation of gravity, known as the general theory of relativity, which Albert Einstein put forward in the early 20th century. Science is a jigsaw puzzle, the theories are the pieces, and as different theories gradually lock together, they give us an ever-expanding picture of how our world works.

The scientific method

“ The important thing is not to stop questioning. ” Albert Einstein

Why's the sky blue? If you don't know the actual explanation, you could probably guess at all sorts of answers—and so could everyone else. If we just asked people what they thought, we could easily end up with 50 or 500 possible accounts. How do we figure out which of these is the right one?

Scientists use an approach called the scientific method . First, they observe or measure something (the sky being blue, for example) very carefully and systematically, which is known as gathering data. (When is it blue? Precisely what shade of blue? Is it ever other colors? When?) From this, they come up with a tentative, logical explanation known as a hypothesis . (It could be something like: the sky is blue because there's water in the air.) The hypothesis should suggest ways in which it can be tested, which are known as experiments . (Is the sky blue on cloudy days, when there's apparently more water in the sky, or dry days, when it's sunnier?) By carrying out experiments, a scientist can test a hypothesis to see if it's a good explanation that accounts for all the evidence.

Although experiments can be quick and simple, they can also be intricate and complex. Most experiments compare a situation where we've deliberately changed something (say, doing more exercise to see if we feel better) with another situation where we haven't. That's called a controlled experiment and it allows us to see whether the thing we change makes any difference. (We can do other experiments that change other things, one at a time, and see what difference that makes instead.) Experiments that come up with mathematical results also have to prove that those results couldn't have happened purely by chance. There are ways of testing experimental data using math and if the data is better than a chance result, we say it's statistically significant .

If a hypothesis can't be tested by experiment, it's usually rejected as bad science from the start. So if your idea of why the sky is blue is that Martians got out their paint pots when you weren't looking, that's essentially untestable: there's no evidence and no obvious way of getting any, so the hypothesis is a non-starter. That doesn't mean a hypothesis has to be tested immediately: sometimes it takes quite a while to devise just the right experiment. Albert Einstein first put forward his general theory of relativity in 1915. But he had to wait four years before another physicist, Sir Arthur Eddington, was able to confirm it , with the help of a famous solar eclipse.

“ Science is a method to keep yourself from kidding yourself. ” Edwin Land

Why is evidence so important to science? Medicine is probably the best example. If you're sick, you want an effective treatment that makes you better; if you're dying, you want a cure. It's perfectly possible that quack cures will sometimes help people get better, either through pure chance or the very intriguing (and very real) placebo effect . But to come up with medical treatments that consistently improve people's lives, we need to carry out experiments and build up evidence that those treatments really do work, consistently, and in all the different groups of people who might try them; we also need to be sure they don't do more harm than good. Science stops us falling into the trap of gullibility—of believing specious ideas (things that sound right that are actually wrong). As Edwin Land, the physicist inventor of the Polaroid camera once said: "Science is a method to keep yourself from kidding yourself."

What is a theory?

If there's good evidence, a tentative and very fluid hypothesis starts to solidify into a more formal, generally accepted explanation of something, which is called a theory . In other words, a theory is a hypothesis confirmed by experimental evidence or other observations. The more and better the evidence, the stronger the theory—and the more things a theory can explain, the better it is. Importantly, evidence for a theory has to come from more than one person or group: in other words, the results of one team's work has to be replicated (repeated) by others. Theories also have to be published and discussed by the wider scientific community (usually in reputable scientific journals) in a process known as peer review , which gives other people the opportunity to spot flaws in your theory or the methods you used to test it. If any evidence contradicts a theory, the theory is either wrong or incomplete, which means a better theory is needed. Sometimes wrong theories come from bad experiments that supply incorrect data or other kinds of misleading evidence. It's important to try to disprove theories ("If we see this happening, the theory must be wrong") and not just confirm them ("If we see this happening, it agrees with our theory"), though it's a sign of a good theory if it can be properly defended against criticism.

Artwork: The Periodic Table is part of a brilliant theory that explains why different chemical elements have similar properties.

The best theories—things like the theory of evolution —have "evolved" (if you'll excuse the pun) over decades or centuries, supported by many different kinds of evidence involving thousands of experiments and studies by many different scientists from all sorts of fields. It can take a long time for an excellent theory like this to be accepted. In much the same way, wrong-headed theories will sometimes take a long time to disappear. For example, it was originally believed that Earth was the center of the universe and the Sun and planets revolved around it. Known as the geocentric theory (literally, "Earth-centered" theory), that was widely accepted in ancient times, but evidence slowly emerged that it was wrong. To get around this, early scientists could simply have thrown that theory away and come up with a totally new one. Instead, what they did was come up with increasingly tortuous fudges to account for the discrepancies. Eventually, scientists like Kepler, Galileo, and Copernicus developed a rival heliocentric theory , in which the Sun sits at the center of things, which is what people believe today. Another commonly believed explanation that lasted a very long time was the miasma theory —the idea that diseases were passed on by bad air. It persisted as a plausible explanation of disease from ancient times right up until the late 19th century, when growing evidence led to a much better explanation known as the germ theory (the idea that bacteria and viruses cause diseases).

Photo: Albert Einstein's theory of relativity wasn't just his throwaway "opinion": it was a explanation designed to account for all the facts Einstein knew about things like light, gravity, and motion. Photo courtesy of US Library of Congress .

It's important to realize that calling something "a theory" doesn't mean it's flaky, speculative, or just an opinion. The theory of evolution is supported by a huge mass of very different evidence and, though there are still gaps in our understanding of how it works, it's generally accepted as the best explanation of how the modern pattern of humans and other living creatures came to arrive on Earth. In other words, it's the best explanation for all the facts that we have. Einstein's original, "special" theory of relativity was also supported by evidence, but there were various things it couldn't explain. That was why Einstein soon developed a deeper, more comprehensive explanation in the shape of his "general" theory of relativity. This, too, has gaps and is by no means a perfect theory (for example, it's an ongoing challenge to reconcile Einstein's ideas with quantum theory, the currently favored explanation of how the atomic world works). Crucially, no scientific theory can ever be proved completely correct: someone could always come up with new evidence tomorrow that disproves it. But that doesn't mean every theory is automatically suspect. If a theory has been around a long time and it's supported by a huge body of different evidence (like the theory of evolution), we can be reasonably confident that it's right. Even so, as the heliocentric theory shows, we can never be complacent: as scientists, our minds should always be open. The key point is that science is a work in progress; it's like a vast jigsaw puzzle that will never be complete.

“ Some claim that evolution is just a theory, as if it were merely an opinion. The theory of evolution—like the theory of gravity—is a scientific fact. ” Richard Dawkins

Types of science

If science is a method —a way of building knowledge about the world—that suggests it's a kind of tool we can apply to all kinds of things. From physics and chemistry to medicine and sociology, scientific methods have been used to study every aspect of our world. Different sciences are very different from one another and range from the highly abstract, mathematical ideas of theoretical physics to the very concrete ideas of medical science, which are firmly grounded in biological observations of how our bodies work.

Science and its rivals

The scientific method—and the fundamental importance of evidence—is the big difference between science and other ways of thinking about our place in the world, including myths, superstitions, art, religion, and things like astrology. You might be a superstitious kind of person who doesn't walk on the cracks in the pavement, but there's no evidence that walking on cracks is either bad or good for you in any way—and no obvious mechanism by which it ever might be. Myths and superstitions may be fascinating and fun, but they're not credible explanations that can compete with science.

Can religion, art, or myth explain things like this? Osiris, the ancient Egyptian god of agriculture and fertility, had green skin, hinting at a connection with vegetation, but that's hardly an explanation! Photograph courtesy of NASA .

Science versus religion?

What about religion? It's perfectly fine to have religious beliefs about why we see colors in the sky or to paint a picture that shows a rainbow forming, but art and religion are a world away from scientific explanations. They might even be based on meticulous observations, but they still lack the logical rigor of scientific theories. You might say "Well, a religious miracle is evidence for [such and such]," but that's hardly a scientific explanation. Miracles aren't testable, they're not repeatable, and they generally have other, more scientific explanations behind them. That's not to say that religion has no value; the value it has as a coherent belief system, which helps people to live morally good, spiritually enriched, happy and fulfilled lives, is very different from the value of science. You can pray, if you have lung cancer, and it could help you in all kinds of ways—but medical treatments, based on years of evidence-based research, are much more likely to cure you.

Science and art

“ To develop a complete mind: Study the science of art; Study the art of science. Learn how to see. Realize that everything connects to everything else. ” Leonardo da Vinci

When people are studying in schools and colleges, they often think of themselves as "arty" or "sciencey," as though there's a sharp line between the two. Arts subjects are meant to be more human, creative, poetic, emotional, and romantic; sciences are considered more logical, rational, methodical, prosaic, and perhaps even a bit plodding and boring. Of course, that's all a matter of opinion: it's hard to think of anything more human than medicine, for example, which is quintessentially scientific. It's never really clear why people want to build high walls between the arts and sciences. A genius like Leonardo da Vinci obviously straddled the divide; modern artists and scientists also work on similar or overlapping problems. You could argue, for example, that, with their pursuit of cubism, artists like Cezanne, Braque, and Picasso were studying very similar problems to scientists like Einstein. Bridget Riley's op-art clearly has much in common with a branch of psychology called psychophysics (which studies how the eyes and brain perceive light, colors, and patterns). Artist Josef Albers was just as much a scientist of color as Isaac Newton or Thomas Young. Less obviously, a sculptor like Rodin was arguably just as preoccupied with gravity (in his own way) as a scientist like Galileo or Newton.

The very short story of science

How did humans come up with the idea of science? What was wrong with myths, superstitions... and all those earlier, older, and often more magically enchanting ways of explaining? Science, ultimately, turned out to be a more successful intellectual engine for powering civilization. It had better answers and more useful explanations; it soon pulled ahead of the pack. It's easy to see why with an example. In hindsight, it's clear how a growing scientific understanding of electricity and magnetism in the 18th and 19th centuries enabled the development of a superb new way of harnessing, storing, and using energy that's been revolutionizing our world ever science. By contrast, it's hard to see how mystical, mythical, religious, or superstitious ways of explaining things like static electricity , lightning, or sparks could ever have spawned such fabulously useful technologies as electric cars or computers . They might be very comforting to people, as self-contained explanations of a kind, but they offer no real value going forward.

Before science

Early civilizations had systematic knowledge—astronomy and math were their strongest suits—but they didn't have what we now regard as science. People certainly made discoveries—fire, for example—and they came up with world-beating inventions like the wheel and axle . They could see those things were effective, but they didn't understand how or why (how a fire burst to life or exactly why a wheel made it easier to push a cart). Nor did they appreciate how one discovery could couple with another to make a third that was even more useful (how a fire could be used to drive a wheel—which was the thinking behind steam engines ). Early people knew how to extract metals like gold and silver from the Earth and how to refine them, but they didn't understand the relationship between different elements or the chemistry of how they combine, which is why they got sidetracked by absurd ideas like alchemy. Knowledge, such as it existed, tended to be practical rather than theoretical and very much more fragmented.

Ancient science

Science was really born in ancient times, with the Sumerians, Egyptians, and Greeks like Thales, Pythagoras, Anaximander, Aristotle, Archimedes, and Eratosthenes. Infatuated with logical reasoning and mathematics, they had both qualitative ("wordy") and quantitative ("numbery") explanations for things. The scientific foundations of physics, botany, zoology, anatomy, physiology, engineering, and medicine were all laid down in ancient times. The Romans who followed the Greeks were, by contrast, more practical and applied scientists, making huge leaps in architecture and engineering.

Dark and Golden science

“ Arabic science throughout its golden age was inextricably linked to religion; indeed, it was driven by the need of early scholars to interpret the Qur'an. ” Jim Al-Khalili

Following the collapse of the Roman Empire, scientific progress stalled in the west, in a time known as the Dark Ages, while the baton of progress passed to the Islamic world in a glorious period of science history now known as the Islamic Golden Age . Al-Khwarizmi (who gave his name to algorithms) developed algebra, Avicenna advanced medicine, Alhazen pioneered modern optics, and Al-Jazari developed ingenious machines. In the Arabic world, the best ideas from Egypt, Greece, China, India, and elsewhere fused and burned like the fuel in a modern-day rocket, before drifting back to Europe at the end of the Middle Ages. Science, in the Golden Age, helped to illuminate religion. And from then on, religious and philosophical ideas slowly started to merge with scientific ones thanks to the enlightened open minds of scholars like Peter Abelard, Thomas Aquinas, Hildegard of Bingen, and Roger Bacon.

The science revolution

True science probably began at the point where the world's best thinkers started to toss aside ancient ideas. Leonardo da Vinci blurred the boundaries between art and science, as never before or science. Another defining figure was Nicolaus Copernicus, who, as we've already seen, challenged the long-held (and religiously defended) idea that God's Earth anchored a "geocentric" Universe. Meanwhile, Belgian Andreas Vesalius published a detailed anatomical textbook superseding the ancient, out-of-date medical ideas of Galen and Avicenna. And Francis Bacon helped to formalize the scientific method.

Copernicus paved the way for Kepler and Galileo, who, in turn, opened the door for Isaac Newton and his insightful theories of gravity , motion , light , and a superb mathematical tool known as calculus (developed in parallel by German polymath Gottfried Leibniz). Meanwhile, Robert Hooke studied plants, animals, and living cells under the microscope , while William Harvey built on Vesalius's work with a pioneering theory of how blood circulates around our bodies and hugely influential ideas about magnetism. Another Robert, Robert Boyle, kick-started the systematic, experimental study of chemistry.

Modern science

In physics, thanks to a steady stream of pioneers from Benjamin Franklin to Michael Faraday, the 18th and 19th centuries were the age of electricity and energy, a fusion of practical and applied ideas, science spawning technology. Over in chemistry, magical ideas like alchemy (which even Newton had toyed with) gave way to more realistic, systematic explanations based on a gradual understanding of the chemical elements as fundamental building blocks of our world. Two key figures here were Frenchman Antoine Laurent Lavoisier, who figured out the logic of how elements fused together in reactions, and Englishman John Dalton, who sketched out the beginnings of our modern atomic theory (the idea that everything is ultimately made of atoms). Their ideas would help Dmitri Mendeleev to figure out how elements related to one another in a theoretical diagram he drew up known as the Periodic Table. Meanwhile in biology, a Swedish botanist named Carl Linnaeus studied the similarities and differences between plants and animals and worked out a neat, hierarchical system of classifying species that we still use to this day. A little later, Gregor Mendel pioneered genetics (the idea that plants and animals inherit important characteristics from their parents). The work of Linnaeus and Mendel held the door wide for Charles Darwin and his life-explaining theory of evolution by "natural selection."

These seeds of modern biology spawned amazing new advances in the 20th century, most notably with Francis Crick and James Watson's discovery of the structure of DNA in 1953, and Frederick Sanger's pioneering work on DNA sequencing. But the 20th century saw many other huge advances, from Einstein's world-bending theory of relativity to Edwin Hubble's idea of the ever-expanding universe. The biggest, most revolutionary advances arguably came with a much deeper understanding of the atomic theory, with discovery piled upon discovery by such brilliant physicists as Ernest Rutherford, Niels Bohr, Lise Meitner, Enrico Fermi, Richard Feynman, and many others.

And this is how the story of science moves forward. Each theory builds on older theories, adjusts them, improves them, or kicks them entirely aside. Theories interlock with other theories, making bigger, better, and more comprehensive explanations. We learn more and more about the world and our place in it, how to solve pressing problems, how to do things better, quicker, or in less environmentally destructive ways. Time moves on, the world moves with it. But thanks to the power of science, humans always move forward , to a better place.

Essays About Science: Top 12 Examples and Prompts

Science can explain almost every aspect of our lives; if you want to write essays about science, start by reading our guide.

The word “science” comes from the Latin word Scientia or “knowledge,” It does indeed leave us with no shortage of knowledge as it advances to extraordinary levels. It is present in almost every aspect of our lives, allowing us to live the way we do today and helping us improve society. 

In the 21st century, we see science everywhere. It has given us the technology we deem “essential” today, from our mobile phones to air conditioning units to lightbulbs and refrigerators. Yet, it has also allowed us to learn so much about the unknown, such as the endless vacuum of space and the ocean’s mysterious depths. It is, without a doubt, a vehicle for humanity to obtain knowledge and use this knowledge to flourish. 

To start writing essays about science, look at some of our featured essay examples below. 

1. The challenging environment for science in the 21st century by Nithaya Chetty 

2. disadvantages of science by ella gray, 3. reflections from a nobel winner: scientists need time to make discoveries by donna strickland.

• 4.  ​​The fact of cloning by Cesar Hill

5. T. Rex Like You Haven’t Seen Him: With Feathers by Jason Farago

6. common, cheap ingredients can break down some ‘forever chemicals’ by jude coleman, 1. what is science, 2. a noteworthy scientist, 3. why is it important to study science, 4. are robots a net positive for society, 5. types of sciences, 6. science’s role in warfare.

“Open-ended, unfettered science in its purest form has, over the centuries, been pursued in the interests of understanding nature in a fundamental way, and long may that continue. Scientific ideas and discoveries have often been very successfully exploited for commercial gain and societal improvements, and much of the science system today the world over is designed to push scientists in the direction of more relevance.”

For South Africa to prosper, Chetty encourages cooperation and innovation among scientists. He discusses several problems the country faces, including the politicization of research, a weak economy, and misuse of scientific discoveries. These challenges, he believes, can be overcome if the nation works as one and with the international community and if the education system is improved. 

“Technology can make people lazy. Many people are already dependent and embrace this technology. Like students playing computer games instead of going to school or study. Technology also brings us privacy issues. From cell phone signal interceptions to email hacking, people are now worried about their once private information becoming public knowledge and making profit out of video scandals.”

Gray discusses the adverse effects technology, a science product, has had on human life and society. These include pollution, the inability to communicate properly, and laziness. 

She also acknowledges that technology has made life easier for almost everyone but believes that technology, as it is used now, is detrimental; more responsible use of technology is ideal.

“We must give scientists the opportunity through funding and time to pursue curiosity-based, long-term, basic-science research. Work that does not have direct ramifications for industry or our economy is also worthy. There’s no telling what can come from supporting a curious mind trying to discover something new.”

Strickland, a Nobel Prize winner, explains that a great scientific discovery can only come with ample time for scientists to research, using her work as an example. She describes her work on chirped pulse amplification and its possible applications, including removing brain tumors. Her Nobel-awarded work was done over a long time, and scientists must be afforded ample time and funding to make breakthroughs like hers. 

4.  ​​ The fact of cloning by Cesar Hill

“Any research into human cloning would eventually need to be tested on humans. Cloning might be used to create a “perfect human”. Cloning might have a detrimental effect family relationship. However the debate over cloning has more pros out weighting the cons, giving us a over site of the many advantages cloning has and the effects of it as well. Cloning has many ups and downs nevertheless there are many different ways in which it can be used to adapt and analyse new ways of medicine.”

Hill details both the pros and cons of cloning. It can be used for medical purposes and help us understand genetics more, perhaps even allowing us to prevent genetic diseases in children. However, it is expensive, and many oppose it on religious grounds. Regardless, Hill believes that the process has more advantages than disadvantages and is a net good. 

“For the kids who will throng this new exhibition, and who will adore this show’s colorful animations and fossilized dino poop, T. rex may still appear to be a thrilling monster. But staring in the eyes of the feather-flecked annihilators here, adults may have a more uncanny feeling of identification with the beasts at the pinnacle of the food chain. You can be a killer of unprecedented savagery, but the climate always takes the coup de grâce.”

In his essay, Farago reviews an exhibition on the Tyrannosaurus Rex involving an important scientific discovery: it was a feathered dinosaur. He details the different displays in the exhibition, including models of other dinosaurs that helped scientists realize that the T-Rex had feathers. 

“Understanding this mechanism is just one step in undoing forever chemicals, Dichtel’s team said. And more research is needed: There are other classes of PFAS that require their own solutions. This process wouldn’t work to tackle PFAS out in the environment, because it requires a concentrated amount of the chemicals. But it could one day be used in wastewater treatment plants, where the pollutants could be filtered out of the water, concentrated and then broken down.”

Coleman explains a discovery by which scientists were able to break down a perfluoroalkyl and polyfluoroalkyl substance, a “forever chemical” dangerous to the environment. He explains how they could break the chemical bond and turn the “forever chemical” into something harmless. This is important because pollution can be reduced significantly, particularly in the water. 

Writing Prompts on Essays about Science

“Science” is quite a broad term and encompasses many concepts and definitions. Define science, explain what it involves and how we can use it, and give examples of how it is present in the world. If you want, you can also briefly discuss what science means to you personally. 

Many individuals have made remarkable scientific discoveries, contributing to the wealth of knowledge we have acquired through science. For your essay, choose one scientist you feel has made a noteworthy contribution to their field. Then, give a brief background on the scientists and explain the discovery or invention that makes them essential. 

Consider what it means to study science: how is it relevant now? What lessons can we learn from science? Then, examine the presence of science in today’s world and write about the importance of science in our day-to-day lives- be sure to give examples to support your points. Finally, in your essay, be sure to keep in mind the times we are living in today.

When we think of science, robots are often one of the first things that come to mind. However, there is much to discuss regarding safety, especially artificial intelligence. Discuss the pros and cons of robots and AI, then conclude whether or not the benefits outweigh the disadvantages. Finally, provide adequate evidence to reinforce your argument and explain it in detail. 

From biology to chemistry to physics, science has many branches, each dealing with different aspects of the world and universe. Choose one branch of science and then explain what it is, define basic concepts under this science, and give examples of how it is applied: Are any inventions requiring it? How about something we know today thanks to scientific discovery? Answer these questions in your own words for a compelling essay.

Undoubtedly, technology developed using science has had devastating effects, from nuclear weapons to self-flying fighter jets to deadly new guns and tanks. Examine scientific developments’ role in the war: Do they make it more brutal? Or do they reduce the casualties? Make sure to conduct ample research before writing your essay; this topic is debatable.

The Concept of Science: Definition and Components Essay

Definition of science, common misconceptions, essential components of science, science as a fundamental approach.

An exponentially increasing volume of information is one of the characteristics of the contemporary world. One of the downsides of such an influx is a growing amount of misinformation resulting from ignorance, misinterpretation of data, and deliberate manipulation. While it is possible to address the problem by applying a scientific approach, this is rarely done, mostly due to the unpopularity of the concept of science in the popular perception. The following paper argues that the concept of science is both relevant and useful in practical terms by analyzing popular misconceptions and identifying key characteristics attributable to the topic.

In order to analyze the concept of science, it is necessary to first consider its definition. While there is no single agreed-upon definition of science, several similarities can be identified. Most commonly, science is referred to as a certain body of knowledge that is organized and systematized to simplify its use whenever the necessity arises. Often (but not always) the definitions also specify the application of specific principles to the process of gaining new facts and systematizing the existing body of knowledge. Finally, some definitions clarify the nature of knowledge by suggesting that science explores the fundamental principles of existence.

These definitions also emphasize the involvement of the scientific method in the process, and this deserves a separate mention. As can be seen from the definitions, in most cases, science is treated as a database of knowledge. In some cases, it is seen as a process of expanding this database whereas only some clarify its nature and the purpose of engaging in scientific inquiry. Importantly, such an approach creates a distorted perception, leading to misconceptions about the concept of science.

One of the most widespread misconceptions is the perception of science as a rigid, immutable collection of rules and principles that inherently resists modification. The two most apparent takeaways in this instance are a reliance on historical data as the definitive authority and the alleged inability (or reluctance) of science to accept new findings and modify the worldview as a result. Both arguments are actively employed by the proponents of various scientific practices and the researchers of paranormal phenomena. The best example for this scenario can be taken from the domain of alternative medicine.

Many advocates of natural medications maintain that science does not approve the use of their remedy of choice because the healing properties involved lie beyond the scope of current scientific knowledge, and they readily point to “authority” as used to suppress any evidence in their favor. Another example is a similar argument used by believers in the paranormal who argue that “traditional science” is unable to accept fringe theories as the consequences would disrupt the established order.

While the latter assertion is certainly true, the remainder of the argument could not be further from the true concept of science. Essentially, these misconceptions treat science as a stagnating system of arbitrarily assigned authorities who are invested in the preservation of the status quo of prevailing knowledge. According to this perspective, all changes are unwelcome, and stability is the main goal of science.

This viewpoint brings up the second major misconception, which treats science as “close-minded” or unable to consider alternative explanations and hypotheses that disrupt the existing order. From this stance, science is often considered inferior to other, more “open-minded” approaches. This argument is commonly found among researchers of phenomena that allegedly cannot be explained in the light of currently available knowledge; they argue that accepting an alternative explanation would resolve the problem and provide useful data, but this outcome does not occur due to the active resistance of conservative scientists.

For instance, it is commonplace to find an online discussion of alien visitation or telepathy wherein one of the sides points to the lack of testable evidence, only to have the other side make accusations about the inability to be open-minded enough to consider something beyond the usual.

At this juncture, it is important to point out that the allegations under consideration are not entirely unsubstantiated. Science is conducted by people, and the human factor inevitably introduces an element of unreliability. It is natural for humans to lean in the direction of a preferred conclusion. To account for this flaw, people develop systems that minimize uncertainty and maximize reliability. Counterintuitively, the most perfected of those that are currently available are treated as an unfortunate barrier to ultimate knowledge.

In order to attain the core of the concept of science, it would be reasonable to identify its principal components. The first is the ability to approach the subject critically and without preconceived notions. Essentially, this is the quality of open-mindedness that science is often accused of lacking. The reason for such a discrepancy is the human factor mentioned earlier. All individuals tend to prefer answers that correlate with their existing beliefs and values, dismissing those that conflict with their already established notions.

In other words, an open-minded process requires its proponents to abandon all wrong assumptions, including those that may be less favorable, convenient, and exciting. To ensure this kind of integrity, science offers a range of strategies and tools that eliminate both conscious and subconscious misconduct. It should also be evident that such open-mindedness is expected to exclude emotion and intuition and rely only on evidence in the process of making inquiries.

The second component involves a falsifiable hypothesis. This component is best illustrated with an example known as the sharpshooter fallacy. If an individual decides to test his or her shooting skills, the most intuitive approach is to shoot at targets and observe the result. In an alternative scenario, it is also possible to hit an object and then claim that this was the intended target or, in a more glaring example, hit a wall with a projectile and paint a circle around the impact point, claiming that the bullet has hit the exact spot identified as a target by a shooter although unknown to the audience.

Certainly, in this case, there remains the possibility that this might be an accurate representation of happenings. However, the allegation cannot be proven unless the targets are set before the shooting takes place. A less apparent but far more common example would be the approach used by investigators of paranormal phenomena such as ghosts. Commonly, the researchers collect data without formulating their goals (shooting the wall) and, after selecting the findings that seem the most convincing—and discarding those that do not, announce their success (drawing a circle around the mark). Thus, their inquiry becomes unfalsifiable and cannot be disproven using the scientific method.

As can be seen from the information presented, the fundamental goal of science is to initiate and sustain the ongoing quest for knowledge. Since the process is known to be prone to errors, the scientific method acknowledges factors that compromise the relevance of any inquiry and constantly updates the instruments that allow researchers to avoid biases and arrive at valid conclusions. It is important to note that while it may seem that these instruments are only relevant in the academic arena, they can actually be applied in a variety of real-life scenarios. The easiest example of such use is the application of critical thinking skills to problems encountered on a daily basis. In addition to an apparent usefulness in a professional domain, a critical approach may be applicable in a variety of situations.

For example, maintaining a critical mindset toward news presented in the media can be helpful in avoiding misinformation and differentiating between speculation, assumptions, responsible reporting, misinterpreted information, and deliberate fraud. By the same token, individual well-being in highly developed societies depends to some extent on the ability to recognize fraudulent claims in communication. Simply put, when clearly understood and appropriately applied, the scientific approach is useful in practical terms both for the individual who uses it and society in general. In addition, contrary to popular belief, science does promote open-mindedness since it allows focusing on significant information and accounts for possible biases that may undermine the value of results.

The concept of science is grossly misinterpreted in the popular perception, possibly due to the lack of an understanding of its fundamentals. It is also apparent that despite a widespread opposite belief, the essential components of science align well with the idea of open-mindedness. Thus, once misconceptions are identified and addressed, it is possible to anticipate a rise in the credibility of the concept and its increasing adoption in a real-life setting.

How to Write a Scientific Essay

When writing any essay it’s important to always keep the end goal in mind. You want to produce a document that is detailed, factual, about the subject matter and most importantly to the point.

Writing scientific essays will always be slightly different to when you write an essay for say English Literature . You need to be more analytical and precise when answering your questions. To help achieve this, you need to keep three golden rules in mind.

• Analysing the question, so that you know exactly what you have to do

Planning your answer

• Writing the essay

Now, let’s look at these steps in more detail to help you fully understand how to apply the three golden rules.

Analysing the question

• Start by looking at the instruction. Essays need to be written out in continuous prose. You shouldn’t be using bullet points or writing in note form.
• If it helps to make a particular point, however, you can use a diagram providing it is relevant and adequately explained.
• Look at the topic you are required to write about. The wording of the essay title tells you what you should confine your answer to – there is no place for interesting facts about other areas.

The next step is to plan your answer. What we are going to try to do is show you how to produce an effective plan in a very short time. You need a framework to show your knowledge otherwise it is too easy to concentrate on only a few aspects.

For example, when writing an essay on biology we can divide the topic up in a number of different ways. So, if you have to answer a question like ‘Outline the main properties of life and system reproduction’

The steps for planning are simple. Firstly, define the main terms within the question that need to be addressed. Then list the properties asked for and lastly, roughly assess how many words of your word count you are going to allocate to each term.

Writing the Essay

The final step (you’re almost there), now you have your plan in place for the essay, it’s time to get it all down in black and white. Follow your plan for answering the question, making sure you stick to the word count, check your spelling and grammar and give credit where credit’s (always reference your sources).

How Tutors Breakdown Essays

An exceptional essay

• reflects the detail that could be expected from a comprehensive knowledge and understanding of relevant parts of the specification
• is free from fundamental errors
• maintains appropriate depth and accuracy throughout
• includes two or more paragraphs of material that indicates greater depth or breadth of study

A good essay

An average essay

• contains a significant amount of material that reflects the detail that could be expected from a knowledge and understanding of relevant parts of the specification.

In practice this will amount to about half the essay.

• is likely to reflect limited knowledge of some areas and to be patchy in quality
• demonstrates a good understanding of basic principles with some errors and evidence of misunderstanding

A poor essay

• contains much material which is below the level expected of a candidate who has completed the course
• Contains fundamental errors reflecting a poor grasp of basic principles and concepts

Scientific Essay Examples

Science is the systematic investigation of the surrounding world through observation and experiments and the process of formulating judgments and hypotheses based on obtained evidence. Given that science can be directed at virtually any question that humans find relevant, so can be an essay on science – starting from questions in natural sciences and ending with social sciences.

Science is always relevant because it is the practice through which virtually any new knowledge is gained and any innovation is achieved.
