Experiment: To test if temperature affects the rate of growth of a plant.
Independent Variable: The temperature in which the plant is growing in (the variable that is change-able and isn't affected by the experiment).
Dependent Variable: The height of the plant (the variable that depends on the experiment to change, which is normally the result).
Controlled Variable: 1. Amount of water used to grow the plant 2. Amount of sunlight available for the plant ETC. (Controlled variables are normally those that ensure that the experiment is fair)
