The Effects of Fan Exposure on Phototropic Response

Seedlings are exposed to a light source from one arm of the tube with a fan blowing on them from the same arm. One group should learn that air flow from a fan is positively correlated with food, so it should start to associate a fan with food. And then the other will learn that the air flow is negatively correlated with food,. and it should associate going in the opposite direction of the fan with food as well.
