Control and variable group on lab experiment?

i did an experiment with 10 peas in salt water and 10 peas in fresh water to see which would germinate quicker. which group was the control and which was the variable?? i always get confused.|||The fresh water is the control as you are not adding anything to it.





The salt is the variable that you are changing to see if it makes the peas germinate any faster.|||Control would be the fresh water to check the peas will actually grow.





The salty water is the variable you are changing.





(well i think that was the point of your experiment anyway)
