Scientific Method

What is the first step in the scientific method?

• Making observations

• Formulating a hypothesis

• Collecting data

• Conducting experiments

In a controlled experiment, the group that does not receive the experimental treatment is called

• Control group

• Experimental group

• Test group

• Variable group

1. Which of the following is a testable statement and a crucial part of the scientific method?

• Dependent variable

• Control variable

• 1. Constant variable

1. What is the purpose of a control group in an experiment?

• 1. To provide a baseline for comparison

• To receive the experimental treatment

• To validate the hypothesis

• 1. To observe natural phenomena

What is the role of a dependent variable in an experiment?

• It is manipulated by the experimenter.

• 1. It is the variable that responds to changes in the independent variable.

• It is kept constant throughout the experiment.

• 1. It is the variable measured before starting the experiment.

• Testable and falsifiable

• 1. All of the above

1. What is the purpose of the scientific method?

• To develop new technologies

• To systematically investigate natural phenomena

1. In the scientific method, what comes after making observations?

• 1. Formulating a hypothesis

• 1. Conducting experiments
