Multiple Choice

Which statement best describes a scientific theory?

A scientific theory is a hypothesis that has not yet been tested.

A scientific theory is a guess or assumption made by scientists.

A scientific theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence.

A scientific theory is a law that has been proven beyond doubt.

Verified step by step guidance

Understand that a scientific theory is not just a simple guess or assumption. It is a comprehensive explanation of some aspect of the natural world.

Recognize that a scientific theory is based on a substantial body of evidence gathered from multiple observations and experiments.

Differentiate between a hypothesis and a theory: a hypothesis is an initial, testable statement, while a theory is a well-substantiated explanation.

Acknowledge that scientific theories are subject to testing and refinement as new evidence becomes available, but they are not considered 'proven' in the absolute sense like mathematical theorems.

Realize that scientific theories are distinct from scientific laws, which describe phenomena that consistently occur under certain conditions, whereas theories explain why those phenomena occur.
