What would be the inde pendant variable for this question will plants grow better in it light or darkness

A variable is part of an experiment that can change, such as amount of light, temperature, humidity, time changes, or plant growth.

In an experiment, an independent variable is a variable that either changes on its own, or you purposely change it.

The goal of an experimental investigation is to determine how changes in an independent variable affects another variable, which is called the dependent variable.

Remember: When designing an Experimental Investigation it is important that you only have one independent variable and one dependent variable. All other variables must be controlled, meaning they must stay the same.
