Project experimentation is the process of testing a hypothesis. The things that have an effect on the experiment are called variables. There are three kinds of variables that you need to identify in your experiments: independent, dependent, and controlled.

The independent variable is the variable you purposely manipulate (change). The dependent variable is the variable that is being observed, which changes in response to the independent variable. The variables that are not changed are called controlled variables.

Answer 6

Variable means a trait or feature that your going to modify and see how it affects the results.  Typically in the scientific method you will only want to change one item at a time.  If you change multiples you don't know which affected the outcome.  Typical examples would be pressure, humidity, temperature, etc.

no fixed value. it can fluctuate.  

Answer 8

Answer 9

A variable is the one thing that changes in a scientific study/experiement.
