Dependent upon the variables, you need to take into consideration factors that can affect the outcome of the result; what will make the result vary in any way.

If this, for example, entails the variable to be kept constant time, you will monitor the time and repeat it throughout the experiment.

This is my understanding of constant variables; hope this helped.

What is the constant variable in investigation of fungi growth mold?

The constant variable in investigating fungi growth mold could be the temperature, humidity level, or type of substrate being used for growth. This variable remains unchanged throughout the experiment to ensure that any observed differences in growth can be attributed to the independent variable being tested.

What are the two types of variables?

The two types of variables are the CONSTANT and CONTROL.

What are two conditions that students keep constant?

Two conditions that students keep constant in an experiment are the control variables (variables that are not changed) and the initial conditions (starting point of the experiment). These conditions ensure that any observed effects are due to the independent variable being tested.

What variables must be kept constant?

Variables that must be kept constant in an experiment are known as control variables. These variables are factors that can influence the outcome of the experiment, so keeping them constant ensures that any observed changes are due to the independent variable being tested.

What is a cotrolled experiment?

It means that except for the independent variable (the only factor that you change) you remain the other variables constant. To keep the control variables the same. Then this is a controlled experiment (fair test). Hope this helps :)

How do you know that a variable is really a control variable and what is the property of control variables?

If you're performing an experiment in which your result depends on multiple variables, but you're just interested in how one of those variables effects the result, you would generally keep all of the other variables constant in order to negate their effects. Those variables that you're keeping constant are called control variables, and you would choose them based on the experiment. For example, say you wanted to determine how changes in resistance effect a circuit's current. Well, current is dependent on not only resistance, but voltage as well, and since you're only interested in the effects of resistance, you would make voltage the control variable, keeping it constant.

What are the variables that are not changed in an experiment?

In an experiment, variables that are not changed are called control variables. These variables are kept constant to ensure that any changes observed in the experiment are due to the manipulated variable, or independent variable, and not due to other factors.

Are constant variables and derived variables the same?

Constant variables are constant, they do not change. Derived variables are not constant. They are determined by the other values in the equation.

What is a control variable in a science project?

It is the variables you will not change to keep the experiment a fair test, they should be kept constant to show how your independent variable affects your dependant variable.

What is the scientific word for what you keep the same?

The control variables.

In a controlled experiment do scientists keep all the variables constant?

Yes they di
