Because mathematical formulas can only describe dynamic changes if some elements (variables) vary in relation to other variables.
Because environmental science involves costs and benefits which, as economic variables, are governed by supply and demand.
A science project that has variables can be an experiment that aquires for variable change.
We Is Doing A Project On Control Variables.
another word for variables are 'things'.
Most science experiments will have two independent variables. Fundamentally, an experiment will want as few variables as possible for better results.
It is important because without controling the variables, you will be testing more than one thing in the expirament at a time. you could get different answers. you only want 1 variable in science expiraments. you might also want a control, with the "normal one" to compare the expiraments with the variables to.
those words either mean math or science words
If you change the variables in a science experiment, you will probably get different results.
Any measurement that can change.

variables are used by being used in science projects
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.
