What variables in an experiment which must remain the same in order to perform a fair test of the independent variable?
Except for the independent variable, all other variables must remain the same between the experimental and control groups.
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.

Why might a test not be fair if different people blow into each straw?
truu
What is an experiment in which only one variable changes?
It's called a 'fair test'
Do you think that using a sneaker with a small amount of mass in it is a fair test of the friction of the sneakers?
NO
What is fair test?
A fair test is when you test something equally changing the variables but keeping everything else the same
When a experiment only has one variable that can change and all other variables are kept unchanged this type of experiment is an?
it is a fair test
What is fair testing in science?
Fair testing is when you test something with many variables, but you must change one variable. e.g. testing the different types ofdrinking water. [Tap water, hose water, etc.
What is a controlled variable in a science fair project?
It is the variables you will not change to keep the experiment a fair test, they should be kept constant to show how your independent variable affects your dependant variable.
What is a plant fair test?
A fair test is something that doesn't change in a test for a plant.
What is a cotrolled experiment?
It means that except for the independent variable (the only factor that you change) you remain the other variables constant. To keep the control variables the same. Then this is a controlled experiment (fair test). Hope this helps :)
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 independent variables should an investigation have?
There can only be one independent and one dependent variable. All other variables should be classed as control variables and must be kept constant to achieve a fair test.
What is the meaning of fair test in science?
a fair test is were you only change one thing
What is a control variable in a science project?
It is the variables you will not change to keep the experiment a fair test, they should be kept constant to show how your independent variable affects your dependant variable.
How many variables can be changed in a fair test?
Only one at a time, since you would not know which variable(s) made the observed changes. You would need to measure each change separately. But if you want to test multiple variables, then you would need to test every possible permutation. If you want to test two chemicals, then you should test your control (a placebo using neither substance), substance A, substance B, and both substances.
Define a fair test?
A fair test has many differences from an unfair test. For example, a fair test is where if you have studied, there would be question-related to what you have gone through like if you are learning density, you would learn how to calculate it. But if the questions are unrelated to your research or what you have been tasked/ assigned, then that would be unfair and therefor wrong.
