To test his hypothesis, the student will have to design an experiment to measure the effects of <u>temperature on cellular growth</u>.

  • Dependent
  • Independent
  • Control

In this experiment, the control variable will be the kind of cells used, as well as the incubation methods being used. We identify these as the control variable given that they will remain constant.

The independent variable will be the Temperature at which we will place each cell being studied. The dependent variable, on the other hand, is by definition, what we seek to measure. In the case given it would correspond to the amount of cellular growth.

To test his theory of the effects of temperature on cellular growth, a student can design an experiment in which the control variable will be the cells themselves, the independent variable will be the Temperature, and the cellular growth can act as the dependent variable.
