Mark wonders if plants will still grow without being watered. To find out, he planted five mongo seeds in each of the two pots (Pot A & Pot B). He kept the soil moist until the seeds germinated and grew into new plants. After germination, he stopped watering pot B but continued watering pot A.
Independent Variable: What variable have you manipulated or changed in your experiment?
Dependent Variable: What variable were you observing or measuring to the variable you have manipulated?
Controlled Variable: What variables have you kept constant or unchanged during your experiment or are the same to all groups?
Control Group: Which group was NOT exposed to the independent variable or serves as the comparison?
Experimental Group: Which group was exposed to the independent variable or shows the effect of the variable that is being tested?

Independent Variable: The independent variable in this experiment is the amount of water supplied to the plants. In this case, it is whether the plants are watered or not.
Dependent Variable: The dependent variable is the growth of the plants. It is what Mark will be observing or measuring to see if there is any difference between the two pots.
Controlled Variables: The controlled variables in this experiment are factors that are kept constant or unchanged throughout the experiment. These include the number of seeds planted in each pot (5 each), the type of seeds (mongo seeds), the type of soil, the amount of sunlight exposure, and the temperature.
Control Group: The control group in this experiment would be Pot A, which is being watered regularly. It serves as a comparison to evaluate the effect of watering on plant growth.
Experimental Group: The experimental group in this experiment would be Pot B, which is not being watered. It shows the effect of not watering on the growth of the plants.
