Constant variable
A constant variable is one that does not change during an experiment. If your experiment includes a dozen cupcakes and that number does not change throughout your experiment, the dozen cupcakes is a constant variable.
The variable that stays the same throughout the entire experiment is called the control.
Scientists change the independent variable but measure the dependent variable; other variables are kept constant.
The constant variable is the one that does not change. The one that holds the same. It is also called the controlled variable an example will be that if you have bucket that you put cement on it and put something after it dried you can't change it.
If you change more that one variable in an experiment, then when the result occurs, you won't know which variable caused the change.
A constant variable is one that does not change during an experiment. If your experiment includes a dozen cupcakes and that number does not change throughout your experiment, the dozen cupcakes is a constant variable.
It is a variable which, under processes of the experiment or study, does not change or is assumed constant.
Controlled variable.
A constant factor is one maintained unchanged throughout an experiment so that it does not affect the outcome. These are also referred to as controlled variables.
So the variable can be at constant.
A constant. It is important to ensure that only one factor changes in an experiment (called the independent variable). All other factors need to remain constant.
Constants
The dependent variable is the variable that can change in an experiment.
a variable factor is anything in your experiment that can change. not like a control factor, which is kept constant through the whole experiment.
The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
Controlled experiment. The thing you change is called the independent variable and the constants are the dependent variables. By only changing the independent variable, any results can be attributed to this.
factors in an experiment that are kept the same and not allowed to change or vary.
