What are variables that the scientist changes in an experiment?

Scientists change the independent variable but measure the dependent variable; other variables are kept constant.


What are the three types of variables?

The three types of variables are: Independent: it is the one that you manipulate Dependent: the one that reacts to the changes in the independent variable and is measured in a experiment Control: all the other factors that could affect the dependent variable but are kept constant through out an experiment


Are constant variables and dependent variables the same?

No, they are not.The constant varible is what stays the same and the dependent varible is whats effected by the change (the independent varibles).


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.


The variables in an experiment that stay the same?

These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.
