So that you can see the difference in your experiment.
A variable that doesn't change in an experiment is called a constant. Constants are used to ensure that only one variable is being tested for its effect on the outcome of the experiment.
"Constant" in science refers to a value that does not change within a given context or experiment. It is a fixed and consistent factor that remains unchanged throughout the study. Constants are important in scientific experiments to ensure that only the variables being tested influence the outcome.
A factor that cannot be changed in an experiment is called a constant. Constants are variables that remain the same throughout the experiment to ensure that only the variable being tested is affecting the outcome.
Constants, also known as control variables, do not change during an experiment. These variables are kept consistent to ensure that the only factor being tested is the independent variable. Examples of constants include temperature, pressure, and time.
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.

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.
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.
You only change 1 iv ( independent variable in a experiment ) HOPE IT HELPS :)
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.
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.
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.
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.
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.
A variable that doesn't change in an experiment is called a constant. Constants are used to ensure that only one variable is being tested for its effect on the outcome of 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.
dependent variable
It's less confusing.
