What was the dependent variable in the experiment? Reflection: (Write down several things you learned that make an independent variable different from a dependent variable) Independent variable These factors have to be kept the same for the experiment to be true. Water one plant every other day an another every day? The growth of the plant would be the dependent variable based on the amount of water recieved.
