Control variables in an experiment
What Is a Control Variable? Definition and Examples
Scientific Method - Controls and Variables ANSWER KEY. Write a definition for each: Control - A part of the experiment that is not being tested and is used for comparison. Variable - Any part of an experiment that can vary. Independent Variable - The part of the experiment that is manipulated or changed by the scientists or person

Control variables are factors in the experiment, other than the independent variable(s) that the experimenter keeps constant. Control variables, therefore, are different from the “control condition” even though they both contain the word “control.”

How many control variables are there per experiment? That depends upon the experiment - but there could be many. In our example, some possible control variables would be: water amount, humidity of the air, air temperature, soil quality, vibration, fauna (bugs), and many others.

Control Group-Independent variable – Dependent variable - Justin B. believes that the temperature lowering during the fall months is what causes the color of the leaves to change. He set up an experiment wherein he placed some plants in 80 degrees rooms and some in 60 degree rooms. He then observed the color of the leaves for a total of 1 month.

Independent and dependent variables: Practice worksheet
Use each description and/or data table to help you identify or describe: 1) any independent variable(s), 2) the best dependent variable, 3) at least 3 variables that should be controlled or held constant, and 4) any control group(s) in the experiment. Make sure your answers are specific. Keep in mind that not all experiments have a control group.
