Nami's Investigation on Plants and the Independent Variable

Understanding the Independent Variable

Independent variable is defined as the variable that is changed or controlled in a scientific experiment. In Nami's investigation, the independent variable is the amount of light given to the plants. This variable is manipulated to observe its effects on the growth of the plants, which is the dependent variable.

Dependent variable is the variable that is being tested and measured in a scientific experiment. In this case, the growth of the plants is the dependent variable. It is the outcome that is being observed and measured to determine the impact of the independent variable - the amount of light.

A change in the independent variable, which is the amount of light in this investigation, directly causes a change in the dependent variable, which is the growth of the plants. By varying the amount of light received by the plants, Nami can study how it affects their growth and draw conclusions based on the results.

Therefore, the independent variable is essential in experiments like Nami's investigation on plants, as it helps determine the cause-and-effect relationship between the variables being studied.
