In a scientific experiment, the dependent variable is what is measured as it is affected by the independent variable. In the first experiment, the number of tomatoes grown depends on the type of soil, so the dependent variable is how many tomatoes grow. In the second experiment, the color of leaves is affected by the amount of light, so the color of leaves is the dependent variable. What is measured in a science experiment is the dependent variable.
