Scientific Method

What is the first step of the scientific method?

• Conduct an experiment
• Formulate a hypothesis
• Make an observation or ask a question.
• Analyze the data

What is a hypothesis?

• A hypothesis is an untestable belief or opinion.
• A hypothesis is a proven fact about the world.
• A hypothesis is a summary of existing knowledge on a topic.
• A hypothesis is a testable statement or prediction about the relationship between variables.

What is the purpose of an experiment in the scientific method?

• To confirm a theory without testing it.
• To collect random observations without a focus.
• To prove that the hypothesis is always correct.
• To test a hypothesis and gather data.

What step comes after analyzing the results of an experiment?

• Repeat the experiment without any changes.
• Publish the results immediately.
• Draw conclusions based on the analysis of the results.
• Ignore the results and move to the next experiment.

What is a dependent variable?

• A dependent variable is the factor that is manipulated by the researcher.
• A dependent variable is the variable that is measured in an experiment, which is affected by the independent variable.
• A dependent variable is unrelated to the independent variable in an experiment.
• A dependent variable is the variable that remains constant in an experiment.

Which step of the scientific method involves gathering information using the senses or tools?

• Conclusion
• Experimentation
• Hypothesis
• Observation

What should a scientist do if their hypothesis is proven wrong after an experiment?

• Publish the findings without any changes.
• Claim the experiment was flawed and redo it without modifications.
• Ignore the results and stick to the original hypothesis.
• Revise the hypothesis and conduct further experiments.

Which of the following is not a step of the scientific method?

• Analyzing data
• Experimenting
• Guessing
• Hypothesizing

What is an independent variable?

• A variable that is measured in response to changes.
• A variable that is only used in observational studies.
• An independent variable is a variable that is changed or controlled in a scientific experiment.
• A variable that remains constant throughout an experiment.

Why is a control group important in an experiment?

• A control group is important because it provides a baseline for comparison, helping to isolate the effects of the experimental treatment.
• A control group is important for making the experiment more complex.
• A control group is necessary to ensure all variables are manipulated equally.
• A control group is used to increase the sample size of the experiment.
