Steffan set up an experiment to test out his theory. He set up a test to compare bees that were exposed to fungicide to a control (bees that were not exposed). What did he find? There was no effect at all. His prediction was not correct

He could not keep the control population from going to plants sprayed with fungicide, so his experiment did not work

90% of the bees in exposed to fungicide got Colony Collapse disorder

Significantly more bees died who were exposed to the fungicide.
