Abstract
The purpose of this experiment was to determine the effect that long-term radio wave exposure could have on the growth rate of vegetal organisms. The specimens used in this experiment were Brassica rapa, or Wisconsin Fast Plants. A Samsung mobile phone was set to stream constantly throughout the trials, providing the EM waves used for study. The independent variable for this study was ….. The dependent variable was ….. The hypothesis was if…, then ….Three trials were included in this experiment. The first trial involved Wisconsin Fast plants that were placed in direct exposure to a constantly streaming mobile device. The second trial placed the Fast Plants a longer distance away from the radio wave emitter. The third and final trial focused on the specimens surrounded by tinfoil, unexposed to the EM signals being emitted by the device. In all three trials, the Brassica rapa were placed in similar environments, with identical temperatures, light, water supplies, and soil. Their height, in mm., was recorded by day for one week, Afterwards, the data was interpreted into position vs. time graphs. After being cut and dried, the aboveground biomass of each specimen was also recorded at the end of the experiment. It was found that both the growth and germination rate of the Brassica rapa was much higher in an environment unexposed to the mobile device. The aboveground biomass showed no noticeable tendencies. These results supported (?) or did not support (?) the hypothesis.
