A science project that has variables can be an experiment that aquires for variable change.
'Manipulating variables' means to change some of the portions of a specific formula that are open to change, and hence variable. Take: ( x + y ) = 5 You may discretionally change the variables x and y to anything from minus infinity to five and the equation will still be solvable. To do so would be to manipulate those variables.
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
list some variables that can change in an experiment?
Some examples of a scientific variable is Independent Variable Control Variables :)
The idea is to work with the same variables, but it is possible that some of the variables are missing in some of the equations.

Because mathematical formulas can only describe dynamic changes if some elements (variables) vary in relation to other variables.
There is no such thing as definite variable in mathematics. Some of the variables in mathematics are independent and dependent variables. More variables are usually found in probability textbooks.
Some variables are if it is new or old, hot or cold, diet or normal
Controlled variables are things that may effect the outcome of an experiment, like temperature are pressure or the amount of some substance used. Dependent variables are those which change due to the conditions mentioned above. These might be speed of the reaction, or the quantity of some product.
Not all dependent variables are measurable. Some dependent variables, such as attitudes or emotions, may be more abstract and subjective in nature. In such cases, researchers often use scales or questionnaires to help measure and quantify these variables.
Only two variables affect batting average - hits and at-bats.
Some moderating variables for the impact of stress include social support, coping mechanisms, personality traits (such as resilience), and genetic factors. These variables can influence how individuals respond to and are affected by stress in different situations.
Causation, correlation...
The basic difference is that exogeneous variables are fully determined outside the system, but predetermined variables are not. Think of an equation where you have some lagged variables that are independent of subsequent error terms (e.g.consumption in the current period depends on some functional that includes the consumption of the previous period). We could say that the lagged variable was already determined in the period before. Asymptotically predetermined variables can be treated as exogeneous.
Test variables are the factors that are intentionally changed or manipulated by the researcher in an experiment, whereas outcome variables are the factors that are measured and affected by the test variables. Test variables are the independent variables that are controlled by the researcher, while outcome variables are the dependent variables that change in response to the test variables. The relationship between the test variables and outcome variables is explored to determine the effect of the test variables on the outcome variables.
