Natural science essays study and describe natural phenomena. Based on experiments and observations, scientists discover laws and propose theories. They also use mathematics and logic to make correct conclusions, so they are capable of predicting some events.
Natural science is a broad term that includes several distinct disciplines. Some specialize in tiny objects, like microorganisms, elements, or atoms. Others explore the infinite space and ephemeral processes of life.
A more academic way to differentiate natural science is not based on the size of an object.
The first area is physical science. It deals with the processes of non-living materials and elements. There is a division into the subfields according to the subject. The main ones are physics, chemistry, Earth science, and astronomy.
We will discuss physics and chemistry in detail later in the article. Meanwhile, Earth science is a general term for the subfields studying ecosystems. It analyzes how all areas of the Earth function and influence each other. Astronomy deals with cosmic objects, such as planets, galaxies, and nebulae. Some scientists combine it with astrophysics. The peculiar thing about it is that you cannot set up an experiment.
The second area is life science, or biology. Its objects are living organisms, their functions, and their behavior.
You may divide this branch of natural science into subfields as well. Zoology studies animals and botany plants. Ecology explores the interactions of living and non-living organisms. And there are many more branches to explore! For example, molecular biology goes hand in hand with chemistry. Or anatomy, which focuses on the insides of humans and animals.
We will provide you with a range of great topics for your paper. Below, you will find writing tips and natural science essay examples!

Territorial morphology The notion of state territorial morphology reflects how the territory of a state is located. There are such types of territorial morphology: compact states, protruded states, elongated states, fragmented states, perforated states (355). Cambodia is a compact state: its shape is almost round; Thailand is a protruded state:...
“Romanticized landscape” by Barry Lopez In his essay, The American Geographies, Lopez deliberates on the essence of nature presented through people’s perception. In particular, the author believes that a romantic vision of the American landscape prevents people from understanding the essence of the real scenery and embraces the overwhelming meaning...
Introduction Water is among the most valuable natural resource found on the earth. The human body can survive for a number of days without food, but its systems will fail without water. The ecosystem requires water in order to supply human beings with food, energy and other resources essential for...

Summary This article discusses some of the essential ideas about camouflage in the wild, an important component of the evolutionary process. There are three main functions disguise plays in nature: worsening detention, imposing difficulties for identification, and redirection of attack. Detection means that camouflage makes it hard for predators to...
Abstract Having a strong sense of self-identity is critical to coping and adapting through transitional periods in a person’s life. Any life change, such as relocating to a new house, starting a new school, and even coping with the loss of a relative, may influence how a person copes with...

Introduction When an acid and a base are reacted, a neutralization reaction occurs whereby a solution and a gas are formed. This experiment tests the effect of temperature, concentration, and surface area on the rate of reaction. Temperature is defined as the degree of hotness or coldness of a substance,...
Introduction Post-translational modification is the process by which a protein (polypeptide) is modified chemically after it has gone through the third stage of protein biosynthesis. This third stage is referred to as translation. It is part of the whole process of gene expression. Basically, a protein is made up of...
Introduction There has been a remarkable breakthrough in molecular biology over the last ten years. Already today, it is possible to read the genetic code of a person and to predict what diseases it will inherit. With the help of gene technology, scientists clone animals, attempt to create children “on...
Introduction Biological systems contain a wide range of fatty acids in cell membranes and stored fat. In particular, the cell membrane of microbial organisms consists of a bilayer of glycerophospholipids in which the fatty acids are esterified to glycerol (Carlsson 1973, p.288). Microbial fatty acids are unique from one species...
Introduction Turkey, as it stands today, was founded in 1923 from the remnants of Anatolia after the downfall of the Ottoman Empire. Mustafa Kemal under whom the country went through a series of legal, judicial, social, and political and economic changes led the country. The country faced military coups in...
Introduction The term blindness is used somewhat misleading in the designation of certain visual conditions in which visual acuity is not significantly reduces. Color Blindness, for example, does not involve a reduction of “visual sharpness and should more accurately be called a color-perception deficiency. Color blindness occurs almost exclusively in...
Introduction The origin of modern species has been the subject of study by many scientists, and it involves contrasting worldviews of creationism and evolution. Most people are adept with the primary arguments that Charles Darwin proposed in his famous book, On the Origin of Species, especially the proposition that the...
The methods and principles of anthropological research have always been a subject of heated debate among many scholars. Overall, it is quite possible for us to say that even now there is virtually no consensus as to this particular question. Our task in this essay is to compare various ethnological...
The map of a country is among the most fundamental of a nation’s security policy. Geography is a very decisive factor in the determination of a nation’s defensive foreign policy. The geographical situation of a country is well on the way of determining whether a country is defensible or not...
The UV-Spectrophotometer This lab instrument is used in the analysis of compounds based on their absorbance in the UV (200-400 nm) and visible (400-800nm) spectra. Its history dates the back to early 1800s when the diffraction grating was invented, enabling researchers to separate a light beam into its wavelengths. The...
Introduction This paper examines the concept of global warming with a focal point on car emissions. It is expected to aid policy makers in national governments, automobile manufacturers, fuel industry CEOs, and city planners. This paper is meant to ensure that authorities across the world, industries and members of the...
Background The instrumental analysis method in a chemical laboratory allows stoichiometrically checking the ratios between reactants, determining the purity of the products, and predicting the course of a chemical reaction. In the present laboratory work, the organic synthesis of 1-bromobutane from 1-butanol as a feedstock is carried out on a...
Introduction The Guadeloupe archipelago is known to have been populated by the indigenous peoples of the Americas as early as about 3000 BC. Guadeloupe is an insular region of France and, consequently, part of the European Union (van den Bel 2022). Guadeloupe is part of the Leeward Islands of the...
