What is a scientific explanation?

A scientific explanation is a detailed account that seeks to clarify and make sense of natural phenomena through empirical evidence and logical reasoning. It involves systematically presenting information and data to support a theory or hypothesis, connecting various pieces of evidence to form a coherent explanation.

Scientific explanations are grounded in the principles of objectivity, reproducibility, and testability, distinguishing them from mere speculation or belief. They aim to provide a clear and consistent understanding of the natural world, allowing for predictions and further exploration of the underlying mechanisms at work.

Understanding the Substance of a Scientific Explanation

A scientific explanation is a vital component in the sphere of science. It refers to a general understanding that provides interpretation to many scientifically observed phenomena, aiding in the comprehension of nature and natural phenomena.

Components of a Scientific Explanation

A scientific explanation consists of several key components which include the description, the explanandum, the explanans, and the laws of nature. Let’s delve deeper into these components.


In a scientific explanation, the description is an account that lays out the phenomena. This is usually a detailed view speaking about the occurrence that has been observed.


The term explanandum refers to a statement that describes the event or phenomena that is to be explained. Essentially, this is the fact or occurrence that needs a scientific explanation.


The explanans refers to the explanation or statements that collectively explain the explanandum. In essence, the explanans provides the cause or reasons that account for the explanandum.

Laws of Nature

These are the universal truths and principles that guide and regulate the activities of the natural world. In every scientific explanation, the laws of nature are evoked to provide informative and factual insights.

Nature of Scientific Explanation

It is important to understand that a scientific explanation is more than just stating facts. Instead, they serve the purpose of elucidating why certain phenomena occur, by linking observations to scientific theories.

Deductive-Nomological Model

The Deductive-Nomological Model or DN Model is an integral part of scientific explanation. This model explains an event based on certain general laws and initial conditions, operating under the principle of deductive reasoning.

Inductive-Statistical Model

Another model is the Inductive-Statistical Model or IS Model, which is based on the probability of occurrence. This model emphasizes statistical relevance, thus providing a scientific explanation for events that do not necessarily follow a strict cause-effect relationship.

Significance of Scientific Explanation

Scientific explanation holds significant value in the arena of science. These explanations advance our knowledge about the natural and physical world around us. By providing a systematic understanding of phenomena, these explanations forge the foundational pillars of scientific knowledge and discovery.

Role in Scientific Research

Inherent in scientific research is the goal of explanation. Scientists work towards explaining the complex patterns, relationships, and occurrences that are found in nature. From cell biology to cosmos astronomy, scientific explanation is pivotal in unraveling the mysteries that concern humanity.

Advancing Human Knowledge

Scientific explanations foster successful predictions, enable technological applications, and refine our theoretical grasp of various domains. Whether it’s weather prediction, developing new vaccines, or understanding climate change, scientific explanations prove invaluable to us.

As we can see, a scientific explanation is an important tool within the scientific community. It is a way to dive deeper into the mysteries of the universe and explore new frontiers of knowledge and understanding.

A scientific explanation is a carefully formulated account that seeks to interpret and understand natural phenomena based on evidence, logic, and principles of the scientific method. It provides a systematic and rational explanation for observed facts and helps scientists make sense of the world around them.
