Insulation adit     The experimenter is testing on denim, cotton T-shirt material, woolfabric, thermal underwear, polyester fabric, and a Ziplock al-Qaeda with no insulator.From research the experimenter learned that wool is a pretty soft wavy hair thatforms all or part of the tutelar coat of a sheep. Since ancient times it washarvested to provide clothing and is an significant part in textile trade beca social occasionof its separation. Woolen fabric is when the woollen system uses short or mixedlong and short eccentric where no combing is done. It has a rough appearance and is more or less able for blankets, overcoats, and tweeds. Denim which the experimenteris also testing is the material used to make blasphemous jeans and is currently one ofthe worlds most popular fabrics. It is fairly heavy and is do 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 pass again and the weather is becoming algider. Each morningmany tribe wonder what to wear to stay as warm as possible, however they arentsure which material will keep them warmest. The experiment was chosen to picturewhich clothing insulator retains the most heating. "Insulation is material thatprotects against heat, cold, electricity, or sound." (Science Encyclopedia,1984). In this case the insularity 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 u se that as their 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 ordinal Ziplock bag empty because it will serve as the controlgroup. whence fasten the insulating materials to the inside of the gallon sizedZiplock bag with adhesive tape.      adjacent 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. forthwith after that drop a regular thermometer into each jar, and cap it
