Ideally, an experiment should test only one variable (the independent variable) at a time.
If you have two or more variables changing at the same time you have no way of knowing which variable is causing your results.
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
You need to consider the results, your hypothesis, and the variables and controls used throughout the experiment.
well they both need to be changed in order to have done the experiment right if it is nott right then do it again
In a scientific method (or experiment), a dependent variable is one that changes throughout the experiment. These are the ones whose changes need to be recorded. Independent variables are those that influence the experiment, but do not change throughout the experiment and remain the same value.
you need a least three and thats not what judges look at they look at neatness, and other stuff you need to work on....
Variables work by telling you what you need to change, what to observe, and what to keep the same in a experiment.

You need to control the variables because if you have two or more variables in an experiment you will never know which variable caused a change or not caused a change.

As many as you need. You can't change more than one if you want accurate results.
In gymnastics you will need to have an experiment for gymnastics when you are doing a research

you need to put them in order
