A variable is anything that can be changed in an experiment to create different results i.e
The variable is the part that is changed in the experiment; the constants are the parts that stay the same.
The independent variable in any item that is changed during a scientific experiment. The dependent variable is the object being tested. In an experiment testing the buoyancy of wood in different solutions, the different solutions would be the independent variable.
A controlled variables are what stayed the same and is compared to other variables
a scientific variable is.......

what are the variable
Some examples of a scientific variable is Independent Variable Control Variables :)
In science, the dependent variable is what is being tested in the experiment. It changes as the independent variable changes, because it depends on the independent variable. The experiment can measure changes in the dependent variable through controlling the independent variable.
An independent variable is not affected by the change of another independent variable. To make an experiment, you generally try to change each independent variable in its turn, leaving other independent variables constant, getting the result (the dependent variable) which was chosen. The results can be exhibited as graphs, where the independent variable serves as abscissa or a parameter, or tables
describes how to measure a variable or define a term. right out of my science book
a variable can be described as a scientific change
