Definition

A fact is a statement that can be verified as true or false. Facts are based on evidence, which can be gathered through observation, experimentation, or other means.

Facts are important in science because they provide a foundation for understanding the natural world. They also help scientists to make predictions and to develop theories.

There are different types of facts, including:

  • Observational facts: These are facts that are based on observations of the natural world. For example, the fact that the Earth is round is an observational fact.
  • Experimental facts: These are facts that are based on the results of experiments. For example, the fact that gravity pulls objects towards the Earth is an experimental fact.
  • Theoretical facts: These are facts that are based on theories. For example, the fact that the Earth is made up of different layers is a theoretical fact.

It is important to note that facts can change as new evidence is gathered. For example, the fact that the Earth was once thought to be flat is now known to be false.

How can the word be used?

The fact that the Earth is round is a scientific fact.

fact

Different forms of the word

Noun: fact, actuality, reality.

Adjective: factual, actual.

Verb: to fact-check, to verify.

Etymology

The word "fact" comes from the Latin word factum, which means "deed," "action," or "event." It was first used in English in the 14th century, and it is still used today to refer to something that is true or has actually happened.

What is a fact?

AQA Science Exam Question and Answer

Question:

Explain the difference between a scientific fact and a scientific theory. Provide examples to illustrate each concept and how they contribute to our understanding of the natural world.

Answer:

A scientific fact refers to an objective and verifiable observation about the natural world. It is supported by empirical evidence and does not change under different circumstances. For instance, "water boils at 100 degrees Celsius at sea level" is a scientific fact as it can be consistently demonstrated through experiments.

On the other hand, a scientific theory is a well-substantiated explanation based on a body of evidence and observations. Unlike a fact, a theory goes beyond a single observation and offers an overarching framework to understand a phenomenon. For example, the theory of evolution explains the biodiversity and adaptation of species over time-based on extensive evidence from genetics, fossils, and observations of natural selection.

Both facts and theories are essential in science. Facts provide the basis for theories, and theories help us understand and predict natural phenomena. They work together to enrich our understanding of the natural world and support the development of new scientific knowledge.
