What is an independent variable in science?
Answer:
An independent variable in science is a variable that is changed or controlled in a scientific experiment to determine its effect on the dependent variable. It is the variable that stands alone and is not changed by the other variables you are trying to measure. In an experiment, the independent variable is the one that is manipulated, while the dependent variable is the one being measured. For example, in an experiment testing how different amounts of water affect plant growth, the independent variable is the amount of water given to the plants. Manipulating the independent variable (amount of water) will allow researchers to observe and measure the impact on the dependent variable (plant growth).
