What are the 8 Branches of Science?

Science is a process of gathering, analyzing, and drawing conclusions from observable evidence that can be communicated and used to make decisions or predictions about the natural world. Science is a way of thinking and questioning, and it is at the core of what we do as humans. This article will discuss what is science as well as the 8 branches of science

What are the 8 Branches of Science?

The 8 branches of science are the following:

  • Biology
  • Chemistry
  • Psychology 
  • Engineering
  • Physics
  • Mathematics
  • Geology
  • Astronomy 

What is Science?

Science is the study of natural phenomena and the changes in them over time. It is a systematic body of knowledge that is continually expanding. 

Science is also the systematic study of the world and the methods used to study it. It is based on gathering observable, empirical, and measurable evidence subject to specific principles of reasoning.

Science is also considered the process of gathering, analyzing, and drawing conclusions from observable evidence that can be communicated and used to make decisions or predictions about the natural world. 

Science is a way of thinking and questioning, and it is at the core of what we do as humans. Science draws conclusions from observable evidence that can be communicated and used to make decisions or predictions about the natural world. 

Science is a way of thinking and questioning, and it is at the core of what we do as humans. It especially uses the scientific method in solving various queries.

What is the Scientific Method?

The scientific method is a process of inquiry that has been applied successfully to gain knowledge and understanding of the natural world. The scientific method is broken down into three main steps: 

  • Observation
  • Hypothesis
  • Experimentation

The observations are where you take note of your surroundings and make a list of what you see. Next, you make a hypothesis about what you’ve observed, and finally, you test your hypothesis with an experiment. 

If the experiment is successful, then you can use the data from the experiment to make a conclusion. The scientific method is based on the idea that knowledge is not based on faith or belief, but rather on objective reality and is the foundation for all science in many different fields.

There are many different branches of science. Each branch has its own unique methods of study and discoveries that have helped us to better understand the world around us.

There are 8 branches of science, which are biology, chemistry, earth science, engineering, physics, mathematics, geology, and astronomy. These eight major branches are further discussed below.


Biology is the study of life and living organisms from the molecular level to the global level. It includes the study of the structure, function, growth, development, reproduction, evolution, and distribution of living organisms. 

Biology is the most comprehensive science that is concerned with the diversity of life. It is the only science that studies living organisms in all their forms. Biology also looks at how different species interact with each other. It is not just about humans, but about everything else in the world.


Chemistry is the study of matter, which can be a very difficult subject to understand. In chemistry, there are two main branches of study: inorganic and organic. 

Inorganic chemistry deals with molecules that are not made of carbon, oxygen, hydrogen, or nitrogen. Organic chemistry deals with molecules that are made of carbon, oxygen, hydrogen, and nitrogen. 

The study of chemistry is extremely important because it is the study of how things interact with each other and how the world around us works. 

This means that chemists are responsible for understanding how things work and what’s happening to them. Chemistry can be studied in many different ways, but most often it is studied through experiments. 

A chemist would take a substance and study how it changes over time to see what happens. Chemists also use their knowledge of chemistry to help solve problems in the world, such as how to make a new type of plastic or how to make gasoline from renewable resources.


Psychology is the study of human behavior. It is a branch of science that deals with the mind and behavior. Psychology is also the study of how people think, feel, and act in relation to one another. 

It is an interdisciplinary field of study that draws from many different fields such as biology, sociology, and neuroscience. Psychologists are concerned with how the mind influences behavior and how behavior influences moods, thoughts, and feelings. 

The term “psychology” comes from the Greek word psyche, which means “soul.” The word was first used in 1638 by the French philosopher René Descartes to describe the science of the soul.


Engineering is the process of designing, developing, making, and testing machines, tools, structures, and systems. This involves the application of scientific principles, using mathematics, and considering the constraints imposed by practicality, safety, and cost. 

In other words, engineers are people who apply science to solve problems in practical ways. Engineers are responsible for the design of all sorts of things such as buildings, bridges, cars, factories, and more.


Physics is the study of the laws and interactions of nature at the atomic and subatomic levels. This branch encompasses a wide range of topics from motion, sound, heat, light, electromagnetism, and many more.

The main goal of physics is to explain how the world works. Physics helps us understand how objects move, react, and behave in certain situations.


Mathematics is the study of quantity, space, structure, and change. It is a field of study that has been around for thousands of years. People have been using mathematics to make sense of the world around them for a long time. 

Mathematics is a set of rules and methods for solving problems. The earliest known use of mathematics was in Egypt in the Middle Kingdom. Today, mathematics can be used in many different ways including in engineering, business, science, and art.


Geology is the study of the solid, liquid, and gas composition of the Earth and its geological processes. It is a major field of science concerned with the solid Earth, the rocks that compose it, and how they were formed. 

Geology is a natural science that studies the Earth’s rocky layers, or strata, to understand how they were formed and how they interact with each other. 

Geology is also the study of the processes that shape the Earth’s surface and the interaction of these processes with living organisms.


Astronomy is the study of objects and phenomena in outer space, including planets, stars, galaxies, and more. Astronomers study the stars and planets in the universe to learn about their formation, evolution, and history. 

They also study how galaxies interact with each other and how they are changing over time. The word “astronomy” comes from the Greek word “astron” which means “star”. 


Science is a fascinating subject. It always keeps us wondering and learning new things. There are many things that scientists have yet to discover, but they always try to find out more. Science is divided into different branches because it is a constantly changing field. There are many different scientific disciplines, each with its own unique methods and conclusions. The branches of science are constantly changing and expanding to be able to answer the questions that arise in the world.

Frequently Asked Questions (FAQs): what are the 6 branches of philosophy?
