In science, an (blank) is created to test a (blank). In order to make the experiment valid, a scientist should only alter one (blank). The variable that a scientist changes is called the (blank) variable. For example, in a experiment where the effect of light on plant growth is tested, the amount of (blank) would be the independent variable. During the experiment, the (blank) variable might cause a change in another aspect of the experiment. This would be the (blank) variable. In the experiment where the effect of light on plant growth is tested, the amount of (blank) would be the dependent variable. The answers are: (growth, dependent, experiment, independent, independent, light, variable, hypothesis)
