Question

For the following experiment, write a possible hypothesis, and then identify the independent variable, dependent variable, and controlled variables. John wants to know what type of liquid helps plants grow taller. He collects samples of water, coffee, and soda, and he finds three sunflower plants that are the same height.

Answer 1

For the hypothesis, you predict what you think is going to happen in the experiment. As for the independent variable, you write what is changed, and for the dependent variable, what is being measured.
