Scientific Method

The first step in the scientific method is to:

• Create a hypothesis

• Make an observation

• Make an experiment

• Determine an independent variable

In an experiment, things that are kept the same between groups are called:

• Constants

• Control Group

• Permanents

• Variables

An observation that has to do with an object's quantity is a/an ___________ observation.

• Qualitative

• Quantitative

• Inference

• Conclusion

An observation that has to do with an object's quality (what you see) is a/an ___________observation.

• Qualitative

• Quantitative

• Inference

• Conclusion

Which of the following is NOT a characteristic of a good controlled experiment?

• Testing/changing only one variable and keeping other factors/variables constant

• Using a control group

• Testing multiple variables at once

• Using a large sample size

The variable that the scientist changes in an experiment (sometimes called the manipulated variable) that causes another variable to change is called the:

• Dependent variable

• Independent variable

• Controlled variable

• Responding variable

The vertical axis (up and down) on a graph always shows this variable.

• Independent variable

• Dependent variable

• control group

• hypothesis statement
