independent variable

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.
The thing you keep the same in an experiment is called a "controlled variable" or "constant." These variables are kept unchanged to ensure that any observed effects can be attributed to the independent variable being tested. By controlling these factors, researchers can more accurately assess the relationship between the independent and dependent variables.
It's only an experiment if 2 or more conditions are compared. Lava in a cup is a science observation or demonstration. To make it an experiment, you would have to compare 2 conditions, for example lava cups with salt vs. lava cups with baking soda while keeping all other variables 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.
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.
otherwise when you change one or more of the other variables involved you will change the values of the variable you are trying to find
The constant is the thing you keep the same because that is what yo are checking, this can be both good and/or bad. The variables are the things that are being measured withinthe experiment. Hope this helped and good luck getting a good grade on whateverit is you needed this for!
Temperature & mass keep constant in Boyle's law. Volume and pressure are variable.
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 :)
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.

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.
