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.
We will provide you with a range of great topics for your paper. Below, you will find writing tips and natural science essay examples!

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,...
Background Alcohol oxidation to aldehydes and ketones is vital during the synthesis of organic compounds. However, bleach can only directly oxidate some alcohols to carboxylic acids, ketones, or aldehydes. The shortcoming emerges because oxidation requires displacement of OH using NaOCl during substitution reaction (Chem 242: Lab Section, 2014). Most organic...

Ms. Shiavo experienced cardiac arrest, which led to brain injury, on February 15, 1990 (Fine, 2005). As a result, the patient’s...
Mammals are vertebrates, and the main distinctive feature separating them from other animals is the presence of mammary glands. Other differentiating characteristics among mammals include integument, skeleton, and internal anatomical features. In modern times, this class of animals exists in three clades – marsupials, monotremes, and placental mammals. Marsupials are...
Introduction A Friedel-Crafts Alkylation reaction is an eletrophilic aromatic substitution reaction that is employed in introducing tert-butyl alcohol sets on an activated benzene derivative ring. Eletrophilic aromatic substitution entails production of a positively charge tert-butyl compound as a result of the reaction between the acid catalyst and tert-butyl alcohol. After...
Executive Summary Flame test and chemical fingerprinting are analytical procedures that are used to identify metals or metalloid compounds. When subjected to heat, metals emit specific electromagnetic wavelengths, thereby, a particular color of light. The results of this experiment show that lithium gives off a red flame, sodium an orange...
The CFTR gene has multiple alterations, which means that the delta-F08 mutation is not the only known one. By the research, and resting on the information provided in the table, there are many other mutations of the CFTR gene that might cause the appearance and development of the disease (Freeman...
One of the world’s most endangered organisms is vaquita (Phocoena sinus), native to the northern Gulf of California. The animal got its name from the Spanish name vaquita, which means little cow. Scientists first identified this animal in 1958 when they found its’ unique skulls on the beach (Manjarrez-Bringas et...
Introduction The world is not just people, flora and fauna that are on the surface. There are great many of other different organisms that exist in the world, but most people do not see them. The marine world is strange and unique; the organisms that inhabit it may be ranged...
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...
Introduction Stem cells are immature cells which are mostly found in multi-cellular organism and they are mainly characterized by their ability to renew through mitotic cell division which later differentiates into ranges of various specialized cell types (James, 2004, p39). Stem cells in mammals are classified into two broad classed...
The argument that geography no longer matters in the 21st century does not hold. Despite the communication, trade, and infrastructural barriers that globalization has broken, the world cannot get to a position where humans can regard geography as irrelevant. Even with the proliferation of globalization, global problems such as climate...
Executive Summary Kenya is a developing country located in the eastern part of Africa. It has a thriving economy and serves as the major communications and logistics hub in East Africa. It borders with Uganda, Tanzania, Somalia, South Sudan, and Ethiopia. According to government statistics released in 2016, Kenya has...
Why don’t the Baltic and North Sea mix? This question has been puzzling scientists for a long time. Aside from being a natural phenomenon, the two seas that meet in the Atlantic Ocean are also mentioned in the Quaran. People used to think that Baltic and North Sea have a...
Introduction The article “The Egg and the Sperm” by Emily Martin provokes discussion by questioning the accepted notions of egg and sperm in popular and academic literature. In particular, it raises highly essential questions about modifications to the common understanding of fertilization, how they are supported by evidence, and how...
Egg The life cycle of butterflies can be divided into four main stages: egg, larva, pupa, and adult. Butterflies are a unique species of insects with a complete cycle of natural transformations, since the first iteration is significantly different from the last. Each observed transition is called metamorphosis, and eggs...
Introduction Ever since biochemical evolutionary processes caused the origin of life on Earth several billion years ago, the drivers of natural selection, heredity, and variability have resulted in a wide range of biodiversity. This diversity is the foundation for questions about what determines the properties of living matter in the...
Introduction The cell is one of the most important topics that form the basic pillars of microbiology. The latter involves the scientific study of the functions and properties of all living organisms that are too small to be seen with the unaided eye (Zeng, 2022). Archaea, bacteria, viruses, fungi, phages,...
Biogeochemical cycles are the transportations and transformations of chemicals in ecosystems (UCAR, n.d.). Some chemicals can be a part of a plant or an animal one day and then be a part of a river the next day. Biogeochemical cycles are of extreme importance for the planet, as they help...
Introduction India has the world’s second largest population. Population explosion presents he problem of food insecurity to India. Food is considered one of the important element in Indian’s culture. Being a diverse culture, different Indian communities have different meals. Some food choices are influenced by religious practices Indians rely more...
Abstract Environmental studies provide learners with an opportunity to advance their knowledge of how organisms interact with their environment. The study enhances one’s knowledge of how the interaction shapes the species of organisms. Some species have gone extinct, while others have undergone significant changes to fit in the new environment....
Testes and ovaries – both testes and ovaries are called gonads, which are the primary reproductive organs. They produce gametes, where the testes in male and ovaries in female produce sperms and ova respectively. Rete testis and rete ovarii – these reproductive organs are homologues where the rete ovarii is...
Acid-base reactions are important in both industrial chemistry and biochemistry. Every day people encounter acid-base reaction products at pharmacies, homes, shops, and even at work. A popular example of these products is sodium chloride which is found in common salt. This paper explains in detail the chemical reaction involved when...
Introduction Lake Mattoon is a man-made water reservoir located in central Illinois. It was created in 1957 to provide an additional source of water for the population of Mattoon and Neoga. Moreover, the lake is continuously stocked with various fish species, including catfish, bluegill, brass, and crappie. Today, lake Mattoon...
Introduction Biodiesel and soap are made through transesterification and saponification. Saponification is the process of reacting a triglyceride with an aqueous hydroxide ion to form glycerol and fatty acid salts (Weldegirma). It is used to manufacture soap.
