Sample Question
The variable that is changed by the scientist is the independent variable and the variable that the scientist is recording data on is the dependent variable. The dependent variable is the variable that is being measured and/or observed. Additional variables know as the constant variables remain the same or constant throughout the experiment. These variables must be kept constant to insure that they do not effect the outcome of the experiment. Based on the following hypothesis: If liquid fertilzer is used then the plant will grow larger, what is the independent variable?

Type of Plant

Type of Fertilizer

Type of Planter
