Question

1. A scientific theory is a set of propositions that defines and explains some aspects of the world. This definition contrasts sharply with the everyday usage of the word theory, which often carries meanings such as "speculations" of "guess". What is the best definition of a scientific theory?

A. A scientific theory can be tested with a repeated experimentation and data to a support or disprove it.
B. A scientific theory follows the steps of the scientific method.
C. A scientific theory is a guess that is then observed to be correct.
D. A scientific theory speculates about eh root causes of life and the universe and then tests those assumptions through extensive modeling.

Answer 1

A scientific theory is a well-substantiated explanation of natural phenomena, confirmed by repeated observations and experimentation, and not a mere guess. It's supported by extensive evidence, can make predictions, and undergoes rigorous testing and verification.

Step-by-step explanation:

The best definition of a scientific theory is option A, which states that a scientific theory can be tested through repeated experimentation and data to support or disprove it. Unlike the everyday use of the term 'theory,' in science, a theory is not a mere guess or speculation. Instead, it is a well-substantiated explanation of some aspects of the natural world that has been repeatedly confirmed through observation and experimentation. Theories in science are robust and reliable accounts of the real world, capable of making predictions about as yet unobserved phenomena, and are supported by a body of evidence that can often make them as factual as any observable phenomenon.

Key points to remember about scientific theories include:

• Theories are comprehensive explanations of natural phenomena based on facts.
• Theories are supported by a considerable amount of scientific evidence and undergo rigorous testing.
• Theories are not static and can change, but such changes require substantial new evidence that challenges the existing theory.
