Scientific Method Quiz

What is the first step in the scientific method?

• Forming a hypothesis

• Making observations

• Posing a question

• Drawing a conclusion

What is a hypothesis?

• A list of materials needed for an experiment

• A prediction about how one variable might affect another

• A step-by-step procedure for an experiment

• A summary of the experiment's results

What is the purpose of the procedure in an experiment?

• To make the experiment more complicated

• To provide a clear, step-by-step guide for completing the experiment

• To list the results of the experiment

• To predict the outcome of the experiment

What is a control group?

• A group that is changed during the experiment

• A group that is used for comparison in an experiment

• A group that receives special treatment

• A group that is not used in the experiment

What is an independent variable?

• A variable that is kept constant

• A variable that is measured or observed

• A variable that a scientist chooses to change

• A variable that is not important

What is a dependent variable?

• A variable that is kept constant

• A variable that changes because of the independent variable

• A variable that is not measured

• A variable that is chosen by the scientist

What are constant conditions in an experiment?

• Factors that change throughout the experiment

• Factors that remain the same throughout the experiment

• Factors that are not important

• Factors that are only measured once

What is the purpose of a conclusion in an experiment?

• To introduce new variables

• To summarize the information obtained and determine if the hypothesis is supported

• To list the materials used

• To describe the procedure in detail

What is the scientific method used for?

• To create new scientific laws

• To solve problems and gather information

• To ignore existing data

• To make random guesses

What is the relationship between the independent and dependent variables?

• The independent variable is measured, and the dependent variable is changed

• The independent variable is changed, and the dependent variable is measured

• Both variables are kept constant

• Both variables are ignored
