Abstract
Dugesia tigrina (Brown Planaria) are known for their species’ ability to regenerate any part of their bodies after any injury, no matter how severe. Due to their small stature, planaria are very susceptible to outside stimulus, like temperature. In this experiment, brown planaria were exposed to different types of magnets while undergoing the regeneration process to test the effect such stimulus could have on this process. It was hypothesized that the effect of the neodymium magnet would cause the regeneration rate of the planaria to increase the most. The experiment was carried out by equally separating 30 into three separate petri dishes. One petri dish had a 2 in x 1/2 in x 1/2 in rectangular neodymium placed inside of it. Another had a 2 in x 1/2 in x 1/2 rectangular samarium cobalt magnet inside it, while the last dish had no magnet inside. All planaria in the dishes were cut horizontally along their bodies and observed and measured each day for 10 days. An ANOVA test was run. The hypothesis that the neodymium magnet would increase the regeneration rate was rejected. At α = 0.05, F(2,6) = 1.703 and p = 0.2596. The regeneration rate, when stimulated by the neodymium or samarium cobalt magnet, had no significant difference. In summary, magnetism did not appear to affect the regeneration rate of Dugesia tigrina in any substantial way. /
