What is a scientific theory?

Back

A scientific theory is a well-substantiated explanation of an aspect of the natural world that is based on a body of evidence and can be tested through experimentation.

Front

Do scientific theories change over time?

Back

Yes, scientific theories can change as new evidence is discovered and as our understanding of the natural world evolves.

Front

What is the primary difference between a law and a theory?

Back

A law describes what happens under certain conditions, while a theory explains why it happens.

Front

Can a scientific law provide an explanation for a phenomenon?

Back

No, a scientific law does not provide an explanation; it simply describes the observed behavior.

Front

What is an example of a scientific law?

Back

Newton's Law of Universal Gravitation is an example, stating that every mass attracts every other mass with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is an example of a scientific theory?

Back

The Theory of Evolution by Natural Selection is an example, explaining how species change over time through the process of natural selection.

Front

What role does experimentation play in scientific theories?

Back

Experimentation is crucial for testing and validating scientific theories, allowing scientists to gather evidence and refine their explanations.

Front

What does it mean for a scientific theory to be well-substantiated?

Back

A well-substantiated theory is supported by a large body of evidence and has withstood rigorous testing and scrutiny.

Front

What is the significance of peer review in scientific research?

Back

Peer review is important as it ensures the quality and credibility of scientific research by having experts evaluate the work before publication.
