Abstract
The purpose of this experiment was to identify which variables placed in the soil sped up the rate of decomposition of a shredded napkin. The different variables in the soil are lumbricus terrestris, Tenebrio Molitor,banana peel, and then a control with nothing in the soil. The hypothesis for the experiment was having Lumbricus Terrestris in the soil will result in the fastest decomposition of a napkin. Three trials were conducted. The experiment was carried out over a course of five weeks. The containers were weighed and had pictures taken of them everyday. After the data was collected, it was analyzed by a single factor ANOVA statistical and analysis test. The data was not statistically significant from each other, but it showed the mass of each container in each trial had decreased. The overall result proved that the original hypothesis was right. The hypothesis stated that adding lumbricus terrestris to the soil would speed up the rate of decomposition the most. After analyzing the data, it revealed that the lumbricus terrestris,in fact, sped up the rate of decomposition of the napkin the most.
