'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.

How do you manipulate variables?

What is experimental research method?
Experiments are studies involving intervention by the researcher beyond that required for measurement. the usual intervention is to manipulate some variable in a setting and observe how it effects the subject being studied.
Why do scientists use experimenting as a method of research?
Experiments can be used to test a hypothesis. For example, an ecologist may set up an artificial environment in a lab to imitate and manipulate conditions that organisms would encounter in the real world. Scientists use experiments to manipulate variables until they find the answer to their question. This is all part of the scientific inquiry.
Factor in an experiment that changes as a result of other factors changing?
A factor in an experiment that can change is called a variable. Variables are used in experiments to test a hypothesis, and someone will manipulate the variable, while keeping something else the same, a control, in order to see how the variables react in comparison with a control.
Why is it so important to control variables in an experiment?
You need to control variables in an experiment so as to make sure that only the variable you are testing and changing is the one affecting the results of your experiment. For example, in an experiment to find the effect of light intensity on the rate of photosynthesis of plant, you'll change light by putting a plant in sun and another in dark but you must not change carbon dioxide level for both plants so by that you have controlled other variables in the experiment(variables which must be the same always in the experiment).
