Why do you only change one variablle at a time in a science experiment?
So that you can see the difference in your experiment.
Why does an investigator change only one variable in an experiment?
So the variable can be at constant.
What are the factors that can change in an experiment called?
Environmental factors if you cannot control them.Variable factors if you can control them.See link below for easy explanation:In an experiment the scientist is able to change the independent variable. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens. - See more at: http://www.chacha.com/question/what-part-of-an-experiment-is-the-factor-that-you-change#sthash.iyH25Jac.dpufIn an experiment the scientist is able to change the independent variable.

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.
Why does the investigator in an experiment change only one variable?
the investigator only changes one variable in an experiment because they need to see how that one variable reacts. if you wanted to see how the dependent variable changed but changed the independent variable you would not see how the one variable reacts.
How many things can you change in an experiment?
You only change 1 iv ( independent variable in a experiment ) HOPE IT HELPS :)
What is an experiment in which only one factor is allowed to vary?
A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.
Hypothesis only becomes a valid argument conclusion after it has been?
A hypothesis only becomes a valid argument after it has been proved. It is only a valid argument if there is proof (i.e. from an experiment).
Why do you only change one variablle at a time in a science experiment?
So that you can see the difference in your experiment.
What does it mean to control the variables in an experiment?
Controls are the things you leave the same when you do an experiment. Variables are the things you affect in an experiment to see if it makes a difference. It depends on the experiment how you would "control" the variable.
Did the color of Copper ( ) sulfate change?
We can not answer this as we were not there to observe the experiment. Only YOU can answer this!
What type of variables are in experiment?
the only variables in an experiment are the independent variables [the thing in an experiment your going to change. and the dependent variables [the thing in an experiment your going to measure.
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.
What is The thing you change in an experiment?
The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
What is bias in a scientific investigation?
Bias in a scientific investigation usually comes in the form of wanting a particular result. This can skew with the process, doing things that an objective experiment would never do, such as only choose certain results as valid.
Why is it imporatant to change systematically only one variable at a time when doing the experiment?
It is important to only change one variable at a time when doing an experiment, because if you change more than one, there will be uncertainty as to which one affected the result.
What is the temperature called when in an experiment you only change the temperature?
dependent variable
