Out of the ten watered bean seeds, only nine came up. That's a great way of thinking about it. In experiments, you have to test one independent variable at a time in order to accurately understand how it impacts the dependent variable. Usually only one variable is measured and an experiment investigates how changing the independent variable affects the dependent . You might also make sure that you use drilling equipment and crews to control for the impact those factors may have on the experiment. Can you identify the independent and dependent variables for each of the four scenarios below? PDF 5.
