All science experiments are performed in a controlled manner which means, there will be a positive control, a negative control and importantly the subject sample(s) who's behavior is not known. The experimental observation must be positive with the positive control sample and negative with the negative control sample, no matter whatever the condition is. Only in this set up the result of a subject (which is the actual unknown experimental sample) would be considered as a faithful result.
Any fault or irregularities of the controls will destroy the authenticity of an experiment.

What does experiment mean in a science fair project?
experiment means
What do you mean by variables?
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.
What does observation mean when you do a science experiment?
It means what you saw during the experiment.
What does control mean in an experiment?
control means to take conrol in a science experiment
What does record mean in science terms?
record in science terms means keeping track of reactions in an experiment to reinforce how to get the same reaction so there is a lot less effort needed in that particular experiment.

it's basically in other terms "research design". Basically you tell how you are to plan your experiment.
