What might cause a scientists to change a scientific theory?
- A.
Some people disagree with it
- B.
New evidence contradicts it
- C.
It is too old
- D.
It covers too broad a topic
Correct Answer
B. New evidence contradicts itExplanation
Scientists may change a scientific theory when new evidence contradicts it. This is because the scientific method relies on empirical evidence and observations to form and modify theories. When new evidence emerges that contradicts the existing theory, scientists are compelled to reevaluate and potentially revise their understanding of the phenomenon in question. This process of updating theories based on new evidence is fundamental to the advancement of scientific knowledge and the pursuit of more accurate explanations of the natural world.Rate this question:

During an experiment if you purposely change the temperature to hypothesis, the temperature is called the?
- A.
Dependent variable
- B.
Responding variable
- C.
Manipulated variable
- D.
Hypothetical variable
Correct Answer
C. Manipulated variableExplanation
In an experiment, the manipulated variable is the one that the researcher purposely changes or controls. In this case, the temperature is intentionally altered to test a hypothesis. Therefore, the temperature is the manipulated variable. The dependent variable, on the other hand, is the variable that is being measured or observed to see how it responds to the changes in the manipulated variable. The responding variable and hypothetical variable are not relevant in this context.Rate this question:
