Which of the following is an accurate definition for a scientific theory?
An educated guess about a phenomenon.
A well-tested explanation that explains why a scientific phenomenon occurs/occured.
A description of something that has happened.
An uneducated guess about a phenomenon.
The correct definition for a scientific theory is:
"A well-tested explanation that explains why a scientific phenomenon occurs/occurred."
To understand why this is the correct definition, we can follow an approach to finding the answer:
1. Read and understand the options provided:
- An educated guess about a phenomenon.
- A well-tested explanation that explains why a scientific phenomenon occurs/occurred.
- A description of something that has happened.
- An uneducated guess about a phenomenon.
2. Analyze the options:
- Option 1: "An educated guess about a phenomenon." While scientific theories often involve educated guesses, they go beyond just guesses and are based on substantial evidence.
- Option 2: "A well-tested explanation that explains why a scientific phenomenon occurs/occurred." This seems to align well with the general understanding of a scientific theory, as it emphasizes that theories are well-tested explanations that provide an understanding of phenomena.
- Option 3: "A description of something that has happened." This option describes an observation or a description but does not capture the explanatory aspect of a scientific theory.
- Option 4: "An uneducated guess about a phenomenon." This option contradicts the idea of a scientific theory, which is grounded in knowledge and extensive testing.
3. Evaluate the options and choose the most accurate one:
Based on the analysis, option 2, "A well-tested explanation that explains why a scientific phenomenon occurs/occurred," is the correct definition for a scientific theory. This option encompasses the rigorous testing, evidence, and explanatory power that scientific theories possess.
Thus, the correct answer is: A well-tested explanation that explains why a scientific phenomenon occurs/occurred.
