insularityIntroduction     The experimenter is testing on denim, cotton tee shirt material, wool theoretical account, caloric underwear, polyester fabric, and a Ziplock basis with no insulator.From research the experimenter learned that wool is a fine soft wavy hair thatforms all or part of the protective coat of a sheep. Since ancient times it washarvested to provide clothing and is an important part in textile trade beca engagementof its insulation. Woolen fabric is when the woolen system uses short or mixedlong and short fiber where no combing is done. It has a rough appearance and is roughly fitted for blankets, overcoats, and tweeds. Denim which the experimenteris also testing is the material used to make blue jeans and is currently one ofthe worlds most popular fabrics. It is fairly heavy and is made with a bluecotton warp and a white cotton filling (Groilers, 1996). The thermal underwearis duofold, with an outer layer made of 65% cotton, 25% wool, and 10% nylon, andan inner layer made of 100% cotton.     Its the winter again and the weather is becoming colder. Each morningmany people wonder what to wear to go forward as warm as possible, but they arentsure which material will keep them warmest. The experiment was chosen to seewhich clothing insulator retains the most heat. "Insulation is material thatprotects against heat, cold, electricity, or sound." (Science Encyclopedia,1984). In this case the insulation will be protecting against a cold temperature.     The hypothesis is if denim, cotton T-shirt material, wool fabric,polyester fabric, thermal underwear, and a Ziplock bag with out insulatingmaterial are tested to see which one retains the most heat, then wool fabricwill retain the most heat because it holds an important place in todays textiletrade because of its good insulation and the fact that it comes from theprotective coat of sheep who need to stay warm and use that as t heir insulator.ProcedureThe first thing the experimenter does is fill the inside of five, gallon-sizedZiplock bags with the insulation material so it is one centimeters thick allaround. Leave the sixth Ziplock bag empty because it will serve as the controlgroup. Then fasten the insulating materials to the inside of the gallon sizedZiplock bag with adhesive tippytoee.     Next the experimenter boils ten pints of tap water and let it cool until(using the candy thermometer) the temperature drops to 49 degrees Celsius. Thenimmediately fill each of the six canning jars with equal amounts of the water.Immediately after that drop a regular thermometer into each jar, and cap it
