PLANARIA HYSTERIA: DOES RED LED LIGHT AID IN THE REGENERATION OF PLANARIA AND PROMOTE WOUND HEALING?, Carley E.Andrews, Deshler High School, Tuscumbia, AL 35674.

This experiment was conducted in order to determine if exposure to red LED light aided in the regeneration of planaria. Thirty whole planaria were cut in halves, and the 60 cut planaria were separated into six different groups that received varying amounts of exposure to the red LED light. Groups 1 and 2 were the control and received no exposure to the red LED light. Groups 3 and 4 were exposed to the red LED light for 60 seconds once per day. Groups 5 and 6 were exposed to the red LED light for 60 seconds twice per day. After a seven day period, the average daily growths and the average total growths of each group were compared. The groups receiving no LED exposure grew a total average of 0.85 mm and a daily average of 0.12 mm. The groups receiving LED exposure once per day grew a total average of 1.60 mm and a daily average of 0.23 mm. while the group exposed twice per day to the red LED light grew a total average of 3.01 mm and a daily average of 0.43 mm. These results show that exposing planaria to red LED light significantly aids in their regeneration, and these results could possibly be applied to the healing of human wounds.
