Ch 1 Lesson 3 and 4: The Scientific Method

What is the first step in the Scientific Method?

• Test your hypothesis

• Construct a hypothesis

• Ask a question

• Analyze your data

What is the independent variable?

• the factor that is purposefully changed by the scientist to test a hypothesis

• the factor that may change in response to something the scientist changed

• a factor that stays the same throughout the experiment

What is the dependent variable?

• the factor that is purposefully changed by the scientist to test a hypothesis

• the factor that my change in response to the independent variable

• the factor or factors that do not change in an experiment

What is a "constant" in an experiment?

• a factor that does not change in an experiment

• the factor that changes in response to something that the scientist changed

• the factor that the scientist changes in an experiment

What is an experimental control?

• the experimental group that is under normal conditions and is used for comparison when the experiment is completed

• the experimental group that is not under normal conditions and is changed by the scientists

What is bias in an experiment?

• an error in the design of the experiment that will make the results invalid

• a factor in an experiment that does not change
