What are the 9 Branches of Science?

In this article, we will be going over the 9 branches of science. Each branch has a different function in the world. Science is an amazing thing, it is so much more than just a topic in school. Science is all around us, it’s in our food, it’s in our medicine, and it’s even in our everyday lives. 

What are the 9 Branches of Science?

The following are the 9 branches of science:

  1. Meteorology
  2. Pharmacology
  3. Aerology
  4. Cosmology
  5. Entomology
  6. Pedagogy
  7. Seismology
  8. Thermology
  9. Cardiology 

What is Science?

Science is a process of learning about the natural world by observing and experimenting. It’s a process of asking questions, looking for answers, and making discoveries. 

Scientists observe the world around them, ask questions, and then make predictions based on their observations. They use these predictions to make new observations and find new questions to ask.

Science is the systematic study of the natural world and the understanding of life, matter, and the universe. It is a set of methods, processes, and beliefs that are used to study the world and increase knowledge and understanding. 

Science has helped us to understand the natural world better, discover more about life, and learn how to use our environment to create new products and technologies.


Meteorology is the study of the atmosphere, its phenomena, and its interaction with the Earth. They do this by using instruments like weather balloons, radar, satellites, and many more. 

Meteorologists study weather and climate, including how the atmosphere and oceans interact to create different weather patterns. Meteorologists also study how these patterns change over time. 

They are involved in a wide range of fields, including climatology, oceanography, and atmospheric chemistry. The word “meteorology” comes from two Greek words: meteoros meaning “weather” and logos meaning “study.” 


Pharmacology is the study of medications and their effects on the body. It’s a science that has been around for thousands of years, but only recently has it become a recognized field of study. 

Pharmacology is the study of drugs and other substances that can help or harm the body in some way. It includes the study of how drugs work in the body, how they affect the body, and what their side effects are.

 It is a field that integrates biology, chemistry, and other sciences to understand the mechanisms of action of drugs. It also studies the side effects of drugs and how to reduce their occurrence. 

The pharmacologist evaluates drugs, the dose, and the possible side effects before deciding whether or not to prescribe them. The pharmacist is a pharmacologist who studies and dispenses medications.


Aerology is the study of the atmosphere. Aerologists study atmospheric phenomena like weather, climate, and the ozone layer. It is a science that relies on both observational and experimental methods to understand how our atmosphere works. 

Aerology is not a science that is focused on studying the earth itself, but it is a science that uses physics, chemistry, biology, and mathematics to understand the weather and climate of the earth. 

Aerology also includes studies of the greenhouse effect, climate change, pollution, and climate modeling. Aerology is also used to predict what will happen in the future.


Cosmology is the study of the origin, evolution, and eventual fate of the universe. It is a branch of astronomy that deals with the nature of the universe as a whole. 

There are many questions surrounding the universe that scientists have been trying to answer for centuries. Some of these questions include “What is our place in the universe?” and “How did it all begin?”. 

The study of cosmology requires a broad understanding of physics, mathematics, chemistry, and biology. The word “cosmology” comes from the Greek word “kosmos” which means “order.” 

The word was first used in the 17th century to describe the scientific study of the universe. The study of cosmology is an important part of astronomy. The universe has been studied for centuries and scientists have made great progress in this field. 


Entomology is the study of insects, and the scientific discipline that deals with the systematic study of the morphology, physiology, development, behavior, and life history of insects. 

It is one of the largest and most diverse branches of biology. In the past, Entomology was not a science but rather an art. People who studied insects would collect them and place them in jars with pins sticking out of them. 

Entomologists would then watch what happened when the insects tried to escape from the pins. The study of entomology dates back to ancient Greece and Rome when Aristotle studied insects and their life cycles. 

This field has grown over the years and has become more prominent in recent decades. With the advancement of technology, Entomology has become more scientific. 

They now use microscopes to study the intricate details of insects and their behavior. Entomologists also study diseases causing insects that affect humans and other animals as well as insect-borne diseases.


Pedagogy is the study of how to teach and instruct. Pedagogy is a teaching method or strategy that guides the learner through a process of education. 

It can be defined as a set of practices, ideas, and methods of teaching and learning. It is a combination of theory and practice and is often used to refer to the study of teaching. 

It is a broad term that can mean many different things depending on the context in which it is used. Some people use the term pedagogy to refer to the entire process of teaching, including planning and implementing a lesson, while others use it to refer specifically to the act of teaching.


Seismology is the study of earthquakes and the seismic waves that propagate through the Earth’s interior. It is a branch of geology, which also includes volcanology and tectonics. 

Seismologists use seismographs to record, measure and interpret data from earthquakes. The word seismology comes from the Greek word seismós, meaning “shaking” or “trembling”.


Thermology is the study of heat transfer and energy production in the human body. Thermologists study the body’s temperature and how it changes to maintain homeostasis or balance. 

The human body is composed of many systems and cells, all of which interact with one another to keep the body operating smoothly. Thermologists study all of these systems, which can include the skin, mouth, lungs, heart, and nervous system.


Cardiology is the study of the heart and the circulatory system. Cardiologists are physicians who specialize in the diagnosis and treatment of heart disease. 

There are two main types of cardiologists, one that focuses on the diagnosis and treatment of heart disease, and another that focuses on research, education, and prevention. Cardiologists are also specialists in electrocardiography (ECG), which is a technique used to diagnose heart disease.


Science is the systematic study of the natural world using observations, experiments, and reason. Science has been around for thousands of years, but it has been the last few hundred years that science has taken off. In the 1800s, scientists began to use statistics to measure and predict the natural world and in the 1900s, they began to use mathematical equations to predict natural events. Today science is a major part of our lives and there are many careers that make use of science

Frequently Asked Questions (FAQs): What are the 9 Branches of Science?

What are the 3 main divisions of science?

  • Natural science
  • Social science
  • Applied science

What is the scientific method?

The scientific method is a way of discovering the natural world by observing, hypothesizing, and testing hypotheses about phenomena. It is a systematic approach to knowledge that relies on empirical observation and logical reasoning. 

What is a scientist?

A scientist is someone who is curious about the world around them and uses this curiosity to answer questions. Scientists are always learning new things and they use their knowledge to help solve problems in the world. They have a wide range of jobs, including working in hospitals, teaching, and researching. Scientists also help create new technologies and products to help people live better lives.
