Abstract In this experiment normal soybeans, that can be purchased in any grocery or local seed shop, and genetically modified soybeans, which were ordered via the Carolina science company, were used to test the effects of temperature and UV light on soybean growth and germination rate. One half of the seeds were then placed in a small 26C incubator and allowed to grow for 8 days. The remaining half of the seeds were put in a tray out in room temperature (about 20C- 25C) for 8 days and allowed to grow. Measurements in cm were taken each day. The next trial a second variable was introduced and this was that the same number of seeds were exposed to UV light and then placed in a heat or control environment. Then the same amount of seeds were planted and were not given and exposure to UV light and planted in both the heat and control environments. These plants were then all allowed to grow for 8 days, and then the trial was repeated.

Need Genetically modified foods are virtually everywhere in today's markets, but scientists and farmers alike often question: are these genetically modified foods harder to grow or more expensive to grow? Scientists have studied the effects of temperature on a soybean’s germination and growth for years on end, and the unanimous agreement is that soybean seeds will grow faster in a warmer environment. The effects of UV light on certain plant growth and germination has also been thoroughly tested. Researchers have found that majority of plants exposed to UV light (in shorter periods of time) have grown normally showing small or no signs of change. However as time and intensity increases the plants begin to die and show signs of sickness or mutation. These two elements were used in my experiment which tests if UV light and also temperature have any effect on the growth of genetically modified soybeans as well as normal soybeans.

Methodology The Effects Of UV Light And Temperature On Genetically Modified Soybean And Normal Soybean Growth 6 (per trial) genetically modified soybeans were exposed to UV light and then placed in a 26C incubator. 6 (per trial) normal soybeans were exposed to UV light and then placed in a 26C incubator. 6 (per trial) normal soybeans were exposed to UV light and then placed at room temperature (25C). 6 (per trial) genetically modified soybeans were placed at room temperature (25C) 6 (per trial) normal soybeans were placed at room temperature 6 (per trial) normal soybeans were placed in an 26C incubator 6 (per trial) geneticall y modified soybeans were placed in a 26C incubator 6 (per trial) genetically modified soybeans were placed at room temperatu re Measurements in cm were taken everyday, each test lasted about a week and a half (8 days) Measurements of the height (in cm) of the plants stem and leaves were taken Quantitative data was taken as well as some qualitative data that was used (plant health) and these were to calculate the mean of these plants.

Null Hypothesis I believe that when seeds are exposed to small amounts of UV light and are placed in a heat environment they will grow faster and healthier than the seeds which have not been exposed to UV light and are placed in a control environment.
