Microwave Radiation Lab

The independent variable for this experiment was the power of microwave radiation. The dependent variable was the cumulative plant height in centimeters. The constants in this experiment were the microwave, microwave duration, amount of sunlight, type of soil, amount of soil, amount of water, environment (same air quality, temperature, etc.), grass seed, number of grass seeds per cup, number of trials per level of I.V. and cups. The control in this experiment was 0 seconds on 100W. For this experiment, a relatively new and fully functional microwave was used. A total of five repeated trials for each level of I.V. were performed for this experiment.
First, the necessary materials were gathered. These include 250 grass seeds, 25 paper cups, 3675 mL of soil, approximately 50 paper towels, a microwave oven capable of being used at 100 Hz, 500 Hz and 900 Hz, one measuring cup with metric units(to measure materials), one liter of water, 125 cm of masking tape, a Sharpie marker, an environment with ample sunlight

For any seeds that did not germinate, the seed length was measured and used towards the data. The plant heights were put into a data table and a mean was found for each level of I.V. for further data analysis. Then, all of the steps from placing the seeds into the microwave to adding the plant lengths together for the final data, including those two steps, were repeated four more times for a total of five repeated trials. Next, all of the steps from placing the seeds into the microwave through the step preceding this one, including those two steps, were repeated for a total of five repeated trials for all remaining levels of I.V., excluding the warm water level(100W for zero seconds, 500W for 30 seconds, 900W for 30 seconds). Finally, all of the plant lengths, including those that did not germinate, were added together for the final
