independent variables are the ones you change (how much watter to give the plant)
dependent variables are the result (how tall the plant is)
constant variables are ones that don't change (the type of plant)
You don't want a lot of the factors && different things in an experiment to be changed because if they are all changed every now and then, it will completely change the experiment.
An experiment must have a control to show what would happen if no factors were changed.
the independent variable
The factors that are kept the same in an experiment are the constants.The factors that aren't kept the same in an experiment are the variables.

There are different types of factors that can change in an experiment. The environmental factors may change, and are out of your control. The variables in the experiment may also be changed but, are usually controlled by the individual conducting the experiment the majority of the time.
Dependent Variable

the independent variable
In an experiment, variables that are not changed are called control variables. These variables are kept constant to ensure that any changes observed in the experiment are due to the manipulated variable, or independent variable, and not due to other factors.
A factor that can not be changed in an experiment
for Apex: the variable is an experiment that is manipulated by the scientist.
The independent variable is the variable that is changed during an experiment.
A control factor is one of the varriables that can be controlled in a science experiment. It is left as a constant without being changed.
