Spread the seeds out on moist paper towels then wrap them a pieces of folded aluminum foil.
Label one side of control group packet "Up". Label the sides of the experimental group "A" and "B". Place the sprouts where they will not be observed.
Allow the beans to sprout for 3 days.
Carefully open the foil and towels and observe the seedlings. Moisten the towels if necessary, then refold the foil. Turn the experimental set of the seeds upside down. Make sure to keep the control seeds right-side up.
Open and observe the sprouts every 2 days, making sure to keep the control sprouts right-side up and turning the experimental group over.
