Variable means 'can change'. If a science experiment is to produce clear information, we should change only one thing at a time. The condition we change is called the independent variable. For instance we might decide to change the temperature of hot water and see how that affects how long potatoes take to cook in it. Temperature is the independent variable, and cooking time is the dependent variable. If we want to be sure that changing the temperature is the only thing affecting the results, we must ensure nothing else changes from run to run. We must keep the size of the potatoes, their variety, the amount of salt in the water and the cooking vessel the same. These are the controls, or control variables.The controls are the substance or material or measurement in the experiment that stays constant and doesn't change while the variable is the object compared to the control which varies in results and can change through out the course of the experiment.

What does controlling other variables mean?
the control variable is the same
Independent and dependent are types of what?
Independent and dependent are types of variables. These variables are used mostly in science and math. When using independent variables you can control them dependent variables you cannot.
What is the scientific word for what you keep the same?
The control variables.
What is the constant variable in investigation of fungi growth mold?
The variables that you keep the same between the control and experimental groups are the constant variables.
What The one factor that differs between a control group and experimental group in a controlled experiment is the?
When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.
Why is it important to identify and control variables?

Is iron and wood is a better thermal conductor to identify independent and dependent variables?
iron is a better thermal conductor but i do not know what you mean by identify independent or dependent variables. in an experiment? i am not sure.
Why would a scientists need to identify and control variables in an experiment?
A scientist would need to identify variables so you could know what to change and what to keep the same. A scientist would need to control variables so you can try to see exactly which factors are affecting the dependent variable (the thing you're measuring). Hope this helped! Because I have the exact same question on my homework!
What does controlling other variables mean?
the control variable is the same
Is it easier to control dependent variables than independent variables in a scientific experiment?
It is easier to control independent variables
Is iron and wood is a better thermal conductor to identify independent and dependent?
iron is a better thermal conductor but i do not know what you mean by identify independent or dependent variables. in an experiment? i am not sure.
What are the variables that are not changed in an experiment?
The control variables.
Andrea is testing balloon rockets by using balloons with different amount of air Identify the three variables Andrea will need to control?
smoothness,weight and strenght
Identifying independent variables and dependent variables?
how do u identify a independent variable
What does variables and control mean in a science project?
The variable is the characteristic being changed while the control is left as is to see what would normally happen.
How do you identify the register variables?
Registry variables can be identified with registry allocation. The programmer will decide on the variables that need to be assigned to the registry, and variables not assigned to the registry will be held in RAM.
What are contorlled variables in science?
