Your experiment should show what the effect of a variable is on the outcome of the experiment. If you have two variables, you don't know which variable contributed what to the outcome.
For example: if want to see the effect that temperature has on water, you'll want to vary your temperature (temperature is a variable) and record your observations on the water. If nothing else is varied during your experiment and you do this experiment in your kitchen at sea level, then you may learn for instance that as you bring water temperature up from -60C to 0C it melts . If, however, you also vary your pressure (pressure is a SECOND variable) during this test, then you may find that if your pressure is 100Pa, as you bring water from -60C, it turns to vapor at ~25C!

What is a controlled vaiable?
A controlled variable is one that remains the same throughout the experiment, i.e., it is not changed
What dose variable mean in science?
A variable is an element in an experiment that you control. There should only be one variable in an experiment or the results will not be accurate.
The most difficult part of an experiment is designing an experiment that tests only one factor?
The most difficult part of an experiment is designing an experiment that tests only one factor.
How many variables should you have when you start an experiment?
An experiment involves three types of variable.The independent variable is the one you are investigating. It is the one which you deliberately vary in the experiment. You should only have one independent variable.The dependent variable is the variable which you measure to get your results. Often there is only a single dependent variable but there can be more.All other variables must be controlled ie kept constant so they do not change the result. There are usually many control variables in an experiment.
How many variables should change in a scientific experiment?
It depends what kind of experiment you do. For some you just need one. For others you may change two variables. In most cases you only change one
