Data Analysis The question being tested is,” Which fabric (cotton,silk, and polyester) will burn the fastest ?” The hypothesis was that the polyester would be the least fireproof out of the three. The independent variable of the entire experiment was the three different fabrics used which are silk , polyester, and cotton . The dependent variable was the amount of time . The most important procedures was step 5,7,9 the conducting of the experiment where you place the patch of the fabric on the stick leave it exposed for one minute to the fire and measuring the time with the stopwatch for the three fabrics. The experiment went mostly well. A couple mishaps did happen but the experimenting passed . To conduct this experiment it was quite a journey. The lighter did not work at first with the wind,but after that the experiment went well. The times appear to prove the hypothesis wrong but the facts help it a little . the averages make sense . there was not a discernible trend in all the data. The silk had a wave like trend with the first trial being the …show more content…

the moral of the data is to tell which fabric the most fireproof fabric. The data relates to the original hypothesis due to the fact that the polyester residue gives you 3rd degree burns and the silk goes up in a puff of smoke. The results make sense they all end up in between the three trials. The one extraneous variable was that the first two trials the lighter did not light due to the wind so the oil drum stove in the backyard was the place where the three trials were tested. The wind may have altered the results because the first two for polyester were longer than third clear sky and the cotton last longer on the windiest trial 2 than any of the three trials. The results may have happened due to the fact that the weather on the two days was different the first day was extremely windy while the other day was clear skies
