The fourth step in the Scientific Method is _______
-
Form a hypothesis
-
Conclusion
-
Acquire data
Correct Answer
A. Form a hypothesisExplanation
The fourth step in the Scientific Method is to form a hypothesis. This involves making an educated guess or prediction about the outcome of an experiment or study based on prior knowledge or observations. The hypothesis serves as a tentative explanation for the phenomenon being studied and provides a framework for further investigation and experimentation. It is an essential step in the scientific process as it helps guide the research and allows for the testing of the hypothesis through the collection and analysis of data.Rate this question:

The fifth step in the Scientific Method is _______
-
Experiment
-
Acquire data
-
Conclusion
Correct Answer
A. ConclusionExplanation
The fifth step in the Scientific Method is "Conclusion." After conducting an experiment and acquiring data, scientists analyze the results to draw a conclusion. This involves interpreting the data, identifying patterns or trends, and making inferences or generalizations based on the findings. The conclusion summarizes the outcomes of the experiment and determines whether the hypothesis was supported or rejected. It is an essential step in the scientific process as it allows scientists to communicate their findings and contribute to the existing body of knowledge in their field.Rate this question:

Data
Correct Answer
A. DataExplanation
Data is the factual information that is collected, observed, or measured and used as evidence or support for reasoning, analysis, or calculation. In this context, data is mentioned along with hypothesis and theory, suggesting that data is one of the known facts that are used as the basis for the reckoning of information. Data provides the empirical evidence on which hypotheses are tested and theories are developed, making it a crucial component in the scientific process.Rate this question:

-
Experiment
-
Hypothesis
-
Observation
Correct Answer
A. HypothesisExplanation
The given set of observations suggests that the answer is "Hypothesis" because in the scientific method, observations are made first, then a hypothesis is formulated to explain those observations, and finally, experiments are conducted to test the hypothesis. Therefore, "Hypothesis" is the most logical and appropriate term to complete the given set.Rate this question:

A unifying principle that explains the facts of the experiment.
-
Hypothesis
-
Theory
-
Observation
Correct Answer
A. TheoryExplanation
A theory is a well-substantiated explanation that is able to explain and predict a wide range of phenomena. It is based on extensive evidence and has been tested and confirmed through repeated experiments and observations. In contrast, a hypothesis is a tentative explanation that is proposed before any evidence is gathered, and an observation is simply the act of noticing or perceiving something. Therefore, a theory is the most appropriate choice as it provides a comprehensive explanation for the facts observed in the experiment.Rate this question:

A concise mathematical or verbal description of a relationship of phenomena that is always the same unde rthe same conditions.
-
Theory
-
Hypothesis
-
Law
Correct Answer
A. LawExplanation
A law is a concise mathematical or verbal description of a relationship between phenomena that remains constant under the same conditions. Unlike a hypothesis, which is a proposed explanation for a phenomenon that requires further testing, a law has been repeatedly tested and confirmed, providing a reliable and predictable explanation for the observed phenomena. A theory, on the other hand, is a well-substantiated explanation that incorporates multiple laws and hypotheses and can be used to make predictions about a wide range of related phenomena.Rate this question:
