Dependent & Independent Variables

By William Katumba

Brainstorm;

Imagine you want to get the best grade on your next test. What are all the different things you could change or do that might affect your grade?
If you wanted to build a paper airplane that flies the farthest distance, what are all the different things you could change about the plane or the way you throw it?

Multiple Choice

The variable that is being tested, counted, or measured and is responding to the independent variable is known as

Control

Constant

Independent Variable

Dependent Variable

Multiple Choice

The variable the is changed on purpose is..

Constant

Control

Independent Variable

Dependent Variable

Match

Mark notices he has dropped calls on his cell phone when he walks into his bedroom. His friend told him to try and wrap aluminum foil around his phone to get better signal. Mark talks on the phone 3 times while walking into his bedroom and drops 2 of the 3 calls. He wraps his phone in aluminum foil and talks on the phone 3 more times while walking into his bedroom. With the aluminum foil on his phone he only drops 1 phone call.

Multiple Choice

What is the main difference between an independent variable and a dependent variable in an experiment?

An independent variable is what you measure, while a dependent variable is what you change.

An independent variable is what you intentionally change, while a dependent variable is what you measure as a result.

Both are factors you measure in an experiment.

Both are factors you intentionally change in an experiment.
