Why is a controlled experiment important to science?
A controlled experiment means that you try to keep all the variables that are involved in the experiment under control apart from the Dependent and the Independent variables to make sure that any results obtained from the experiment have been affected by the independent variable and not some other extraneous variable. It also ensures that the experiment would have high validity. That is, if the experiment has really measured what it was supposed to measure.
What are some science experiments with variables?
A science project that has variables can be an experiment that aquires for variable change.
How many variables do you need in a science experiment?
Ideally, an experiment should test only one variable (the independent variable) at a time. If you have two or more variables changing at the same time you have no way of knowing which variable is causing your results.
How does a controlled experiment compare results?
A controlled experiment compares results through various methods. Some being a graph, an average, a diagram... etc.
List some variables that can change in an experiment and discuss the importance of a control group?

What is the differences between dependent variables and controlled variables in an experiment?
Controlled variables are things that may effect the outcome of an experiment, like temperature are pressure or the amount of some substance used. Dependent variables are those which change due to the conditions mentioned above. These might be speed of the reaction, or the quantity of some product.

How are variables being manipulate?
A variable in an experiment can be manipulated by changing some aspect of the experiment.
Why do you need a controlled experiment?
In order to conclusively prove or disprove something. i.e an uncontrolled experiment will have so many variables that nothing can be conclusively proven from it, since it could be argued that the outcome could have been caused by any of the uncontrolled variables. Whereas by controlling some of the variables, the ability to prove that one variable links to a certain outcome is easier to establish.

The difference between the independent and dependent variables?
Independent variables are variables that can be changed in an experiment, while dependent variables are variables that change as a result of an experiment. In other words, independent variables are what you change, and dependent variables are the results of the experiment.

Anything that affects the outcome of an experiment?
They are called "variables", and there are three forms.The dependent variable is the result of the experiment or function.The independent variable is the one that is deliberately changed to observe the effect on the dependent variable.The controlled variables should be maintained constant during the experiment so as not to influence the result.
How do hypothesis help in doing some experiment?
Because it will perform a test of how two variables might be related. This is when you are doing a real experiment.
Can there be more than one independent variables in a experiment?
In general yes. But it really depends on the experiment. If you want to know if it hurts to punch a wall, you don't need an independent variable (unless you want to compare the magnitudes of the pain). But for school experiments, most of the time, if not all of the time. Yes.
