Anything that can be changed in any way is a variable. so,,,,,an infinite number.
Day, time, heat, light, humidity, speed, what you ate for dinner the Wednesday before you go shopping.
So, quite literally, an infinite number.
Hope this helps.

∙ 12y agoThere are 3 variables in an experiment, basically. They are Dependent, Independent and Controlled variable.
Firstly,Dependent variable means the thing you want to observe.In other words,the scientist focuses his or her observations on the dependent variable to see how it responds to the change made to the independent variable. The new value of the dependent variable is caused by and depends on the value of the independent variable.
Independent Variable means the thing that you change while doing your observation.In other words,the independent variable is the one that is changed by the scientist.
And the Controlled Variable means the thing(s) you remain constant through your observation.
I wish this could be useful for you :)
Good luck

∙ 10y agoIt depends on the experiment. The independent variable is what you "control" (change around) so as to produce different results from the dependent variable. Experiments must also have a control variable, or one that remains unaffected throughout the experiment, so that you can have something to compare your other results to.

∙ 13y agoYou can have any number of controlled variables. There is no limit. You can only have 1 UNCONTROLLED variable.

∙ 12y agoYou should only change one variable at a time.

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
How many variables does a controlled experiment have?
An experiment of any kind can have infinitely many variables. A controlled experiment can have just as many, provided that all but one are kept exactly the same.
How many variables would you change in a controlled experiment?
You can only change ONE at a time. That's what makes it controlled. It's the only sure way to know what actually changed the experiment.

When controlled experiment is not possible why do scientist try to identify as many relevant variables as possible?
to gather data from data to create an controlled experiment

How many variables should an experiment test at a time?
Only one, because if you do two or more, you won't know which one caused a change,
The variable that changes as the result of an experiment is a?
true or false : in order to get the best results from an experiment, change as many variables as possible within the experiment?
How many variables do you change at one time during an experiment?
You only change one variable; if you changed multiple variables you wouldn't know which one caused a change.
How many variables do you test within one experiment?
Generally speaking, you only want to test a single variable within one experiment so when a change occurs you know what caused it. If you change multiple variables at once it is harder to attribute the change to a single cause.
How many variables does a controlled experiment have?
An experiment of any kind can have infinitely many variables. A controlled experiment can have just as many, provided that all but one are kept exactly the same.
