An experiment should test only one variable (the independent variable) at a time.
If you are testing more than one variable at a time, you have no idea which variable is causing which effect.

What is true about a controlled experiment?
Scientists perform controlled experiments in order to reduce as many third variables as possible. This means they are trying to prevent variables not directly related to the study from influencing the results.
What is science variables?
Variables are the different thing in the experiment. Ex.-Problem-Which ball rolls fastest? Hypothesis-The Softball will roll fastest. Investigation-Roll the balls at the same time and time them with a stopwatch. Conclusion-Basketball rolled the fastest. Variables-The balls.
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.
Is there a relationship between the phases of the moon and the weather a testable question?
Yes it is testable, because both the moon phase and the weather are observable and quantifiable variables. Therefore, their covariability can be determined and this hypothesis tested.

How many variables are tested during an experiment?
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
How many variables are tested in a controlled experiment and why?
It depends on the experiment. Normally only one is tested at a time because they can affect the experiment. Variables are tested in a controlled experiment to see whether they affect the outcome and also how.
How many variables should be tested on the experimental group in an experiment?
