This prevents the motion of the pots inside the cups. Place the cups near a window or under a plant light. Prepare pots in plastic cups as explained in steps 1-2 above. Secure pellets to the plastic cup by pushing unfolded paper clips all the way through the cup and the pellet. Attach plastic cups to the clinostats using rubber bands and paper clips as illustrated below.
Rubber bands go through the perforations found at the base of the rotating part of the clinostat.
Plant seeds as explained in step 3 of Earth conditions. Make sure the cup and pot are centered on the clinostat before turning it on. Place clinostat and pot near a window or under a plant light. Measurements and observations. Data analysis- mathematical mean.
