why does everything in the experiment exept for the varaible need to stay the same
In order to isolate and identify the effect of the variable being tested, it is important to keep all other factors constant. This allows for a more accurate and reliable assessment of the relationship between the variable and the outcome. If other factors were to vary, it would be difficult to determine whether any observed changes were due to the variable being tested or to external factors.
The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
a variable is the thing that we change during the experiment while control is the thing that we remain it to be constant through the whole experiment.
the independent variable
The independent variable changes during an experiment.
A variable in science is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by a scientist in the experiment. The depended variable is what you measure in the experiment and what is affected during the experiment. A controlled variable is one which the researcher holds constant (controls) during an experiment.
A constant variable is one that does not change during an experiment. If your experiment includes a dozen cupcakes and that number does not change throughout your experiment, the dozen cupcakes is a constant variable.

the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.

* independent variable:in an experiment there is only one variable and its set by the person carrying out the experiment . * dependent variable: measured in all set ups during the investigation. * controlled variables: are quantities that the scientist wants to keep constant. so , the part of the experiment that does not depend on the variable is the controlled variable.
The dependent variable is the variable that can change in an experiment.
A manipulative or manipulated variable in an experiment is the variable that can be varied to give different results during the course of an experiment. For example to determine how much sugar will saturate a liter of water, we keep increasing the amount of sugar until the water becomes saturated. Here sugar is the manipulated variable. Very easy! At first, I was confused with it too!
