In a seed germination experiment, what are the negative and positive controls.
Â
Variable 1: One set of beans was soaked overnight the other not soaked.
Variable 2: One set placed in direct sunlight the other not in sunlight.
Variable 3: One set of beans no oxygen and the other had an open container.
Â
I am struggling with what the controls are and how to record them in my results.
