Insulation

Insulation

Introduction

     The experimenter is testing on denim, cotton T-shirt material, wool
fabric, thermal underwear, polyester fabric, and a Ziplock bag with no insulator.
From research the experimenter learned that wool is a fine soft wavy hair that
forms all or part of the protective coat of a sheep.  Since ancient times it was
harvested to provide clothing and is an important part in textile trade because
of its insulation. Woolen fabric is when the woolen system uses short or mixed
long and short fiber where no combing is done.  It has a rough appearance and is
most suitable for blankets, overcoats, and tweeds.  Denim which the experimenter
is also testing is the material used to make blue jeans and is currently one of
the world's most popular fabrics.  It is fairly heavy and is made with a blue
cotton warp and a white cotton filling (Groilers, 1996).  The thermal underwear
is duofold, with an outer layer made of 65% cotton, 25% wool, and 10% nylon, and
an inner layer made of 100% cotton.
     It's the winter again and the weather is becoming colder.  Each morning
many people wonder what to wear to stay as warm as possible, but they aren't
sure which material will keep them warmest.  The experiment was chosen to see
which clothing insulator retains the most heat.  "Insulation is material that
protects 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 insulating
material are tested to see which one retains the most heat, then wool fabric
will retain the most heat because it holds an important place in today's textile
trade because of its good insulation and the fact that it comes from the
protective coat of sheep who need to stay warm and use that as their insulator.

Procedure

The first thing the experimenter does is fill the inside of five, gallon-sized
Ziplock bags with the insulation material so it is one centimeters thick all
around.  Leave the sixth Ziplock bag empty because it will serve as the control
group.  Then fasten the insulating materials to the inside of the gallon sized
Ziplock bag with adhesive tape.
     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. Then
immediately fill each of the six canning ...
