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.
What is the definition of idependent variable?
An independent variable is a part of an experiment that might change due to the outcome not being a desired result. The person conducting an experiment about how a medicine might affect a person, might change the number of people tested to gain more insight into the results. The independent variable in that situation would be the number of test subjects.
What is a Control and a constant in elementary science terms?
A control in science is in an experiment that makes sure the science experiment only tests one variable. A constant is in an experiment and that is a variable that never changes.
What is a science experiment?
An experiment is something like if we don't know if, for example, the result of salt solution. Then we must do it for real to find out the answer. An experiment is not only in the science lab. We can do an experiment everywhere, such as: Our homes, the park,... So that's what a science experiment means. People who haven't done an experiment yet must try some time.
Science investigates only the?
controlled experiment and observations..i might be wrong
How many things can you change in an experiment?
You only change 1 iv ( independent variable in a experiment ) HOPE IT HELPS :)
What is the experimental variable and what is the dependent variable?
the experimental variable is like the independent variable, which is the only thing you can change in a science experiment, and the dependent variables are the things that stay the same.
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.
Discuss the observation process used in science?
The observation process in science is to observe the things given in the experiment you are doing.. or you give your own observations about the experiment you are doing.Always state your observations only with the experiment you are working on not on others experiments.
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.
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
