variables
The factors which you change (vary) are called variables.
changable factors
invisible "factors" - now called genes.
The change of mass can be considered a dependent variable in certain situations, such as in experiments where mass is measured before and after a process or reaction. The change in mass depends on the conditions or factors that affect it, making it a variable that is influenced by other factors.
Variables
In an experiment, factors that you change are called independent variables.
When you change the order of the factors in a multiplication equation, it is called the Commutative Property of Multiplication. This property states that changing the order of the factors does not change the product. Similarly, when you change the order of the addends in an addition equation, it is called the Commutative Property of Addition. This property states that changing the order of the addends does not change the sum.

field experiments
Scientists record experiments in trials.They repeat experiments over and over again so they can find averages.Also,experiments in different conditions,called varibles,could change.But the main reason is the outcome would change
A testable statement used for making predictions and carrying out further experiments is called a hypothesis. The hypothesis might change as the scientist continues to test his or her theory.
