In a properly designed experiment, it is important to have at least 2 controlled variables. With two variables you are able to remove one at a time and see the effect in your setup.
An experiment is a procedure carried out to verify, refute, or establish the validity of a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated.
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group. A control experiment is designed to check or correct the results of a previous experiment. It does this by removing the variable or variables operating in the other experiment. The comparison obtained is an indication or measurement of the effect of the variables concerned
Scientists have very different life styles, one from another. There is no single "scientific lifestyle." So how a given scientist lives might be either a cause or effect of that scientist's brilliance - presuming that scientist is brilliant, not all are - or it may have no relation at all to how brilliant a scientist is.
'Known' Variables
The variable that a scientist changes in an experiment is called the independent variable. This is the variable that the scientist manipulates to observe its effect on the dependent variable.
Starting the experiment without clearly defining the research question and objectives would not be an appropriate first step. It's crucial to have a clear understanding of what you want to investigate and achieve before conducting any experiment.

The variable that a scientist observes to change while conducting an experiment is called the independent variable. This is the variable that is deliberately manipulated by the scientist to observe its effect on the dependent variable.
An inappropriate first step would be to start the experiment without conducting a literature review to understand existing knowledge on the chemical and its reaction to heat. This background information is essential for designing a relevant and informative experiment.
The factor that the scientist changes or manipulates in an experiment is called the independent variable. It is the variable that is intentionally varied to observe its effect on the dependent variable, which is the outcome being measured in the experiment.
The factor a scientist changes in a controlled experiment is called the independent variable. It is the variable that is deliberately manipulated or varied by the scientist to observe its effect on the dependent variable.
The scientist wants to design an experiment that will demonstrate the effect of the independent variable on the dependent variable. This idea is to show causality between the two.

The manipulation of an independent variable during a scientific experiment allows a scientist to find a cause and effect relationship between variables. This is because the manipulation changes the results and measurements.
