Describe a controlled experiment to test this hypothesis, identifying the independent variable, dependent variable, and at least two control variables. A gardener hypothesizes that watering plants with rainwater will make them grow faster than watering them with tap water. Describe a controlled experiment to test this hypothesis, identifying the independent variable, dependent variable, and at least two control variables. A student hypothesizes that the type of liquid used to water a plant will affect the number of leaves it grows. Describe a controlled experiment to test this hypothesis, identifying the independent variable, dependent variable, and at least two control variables.”
