Constant/controlled variables are variables that remain the same throughout an experiment. For example, if you wanted to see whether light affected how well plants grow, you would feed them equal amounts of water, so that the only variable affecting their growth was light exposure.

In a controlled experiment do scientists keep all the variables constant?
Yes they di
Define manipulated responding and controlled variables?
the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.
Why cant you draw a conclusion about the effect of one variable in an investigation when the other key variables are not controlled?
If none of the variables are constant (or controls) you have no idea which variable or combination of variables caused the effect.
Why is it important to have a constant in an experiment?
In order for the results to be valid, the dependent variable can only be affected by the independent variable, so somethings need to be kept CONSTANT. The things that need to be kept constant are called CONTROLLED VARIABLES. Even if controlled variables are affecting the dependent variable(s), which they usually do, keeping them constant will ensure that all trials of an investigation were equally impacted by the controlled variables, therefore allowing one to see the impact of an independent variable on the dependent variable. All in all, a 'constant' in a science experiment should actually be called a 'controlled variable' and the description of such a variable is described in the third point. Hope this clarifies.
Does a controlled experiment have all variables held constant?
all but 1...the 1 yu want tu test.
In an experiment what are controlled variables?
Controlled variables are quantities that must remain constant.
What is the controlling variables?
Controlled variables are quantities that a scientist wants to remain constant and observe as carefully as the dependent variables.

What controlled variables in science?
The number of dependent variables in an experiment varies, but there is often more than one. experiments also have controlled variables are quantities that a scientist wants to remain constant, and he must be observe them as carefully as the dependent variables.
What is your controlled variables of a lemon?
Some controlled variables when using a lemon for an experiment could be its size, ripeness, temperature, and the method of extraction of the lemon juice. These variables should be kept constant throughout the experiment to ensure that any changes observed are due to the manipulated independent variable and not these controlled variables.
What is a variable in a controlled experiment?
In a controlled experiment, the control variable is the one specific thing that is kept constant to measure the change of the other variables. Those variables are the parameters that are being tested.
When a scientific experiment is carried out in a controlled setting all variables are kept the same except for the variable.?
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.
