Scientific Method, Properties of Matter, Measurement

What is the first step of the scientific method?

• Form a hypothesis

• Collect data

• Ask a question or identify a problem

• Draw a conclusion

What is the purpose of the hypothesis in the scientific method?

• To propose a possible explanation or prediction for a phenomenon or observation.

• To summarize the results of a scientific study.

• To gather data and conduct experiments.

• To prove that a phenomenon or observation is true.

What is the difference between an independent variable and a dependent variable?

• The independent variable is manipulated by the researcher, while the dependent variable is measured or observed and is affected by the independent variable.

• The independent variable is measured or observed and is affected by the dependent variable.

• The dependent variable is manipulated by the researcher, while the independent variable is measured or observed.

• The independent variable is the outcome of the experiment, while the dependent variable is controlled by the researcher.

What is the purpose of conducting experiments in the scientific method?

• To prove theories and concepts.

• To collect subjective opinions.

• To analyze historical data.

• To test hypotheses and gather empirical evidence.

What is the role of control variables in an experiment?

• Control variables have no impact on the experiment outcome.

• Control variables are used to manipulate the dependent variable.

• Control variables are only used in observational studies.

• Control variables help in establishing a cause-and-effect relationship between the independent and dependent variables.

What is the final step of the scientific method?

• Conduct experiments

• Communicate the results

• Analyze the data

• Formulate a hypothesis

What is the purpose of analyzing data in the scientific method?

• To collect more data and increase sample size.

• To validate preconceived notions and biases.

• To draw conclusions and make evidence-based decisions.

• To make random guesses and assumptions.

What is the difference between qualitative and quantitative data?

• Qualitative data is numerical and objective, while quantitative data is descriptive and subjective.

• Qualitative data is based on observations, while quantitative data is based on experiments.

• Qualitative data is used for statistical analysis, while quantitative data is used for qualitative analysis.

• Qualitative data is descriptive and subjective, while quantitative data is numerical and objective.

What is the importance of peer review in the scientific method?

• It ensures the quality and validity of research.

• It increases the cost of research.

• It limits the diversity of ideas.

• It delays the publication process.

What are some limitations of the scientific method?

• Subjectivity, lack of reproducibility, reliance on empirical evidence, inability to prove causation

• Observable phenomena, bias, metaphysical claims, limited scope
