Insulation

Insulation

Objective- The weather conditions like rain, snow, wind, can cause our bodies to lose as much as heat. If we do not pick up the right materials that can keep our body warm and toasty, we will start to shiver and wearing warmer and insulating clothes, which allows us to stay fit and fine. In this experiment, let us learn, which type of clothing fabric gives us the best insulation in various weather conditions.

Requirements –

  • 7 glasses having similar size and shape
  • Thermometer
  • Water
  • Cotton
  • Wool
  • Denim
  • Fleece
  • Nylon
  • Lace
  • Kitchen timer
  • Notebook and a pencil

Procedure –

  1. Gather all type of fabrics such as Wool, denim, lace, cotton, fleece, and nylon.
  2. Look the fabrics, which you will be testing as to which one will be the best in keeping the water temperature from dropping? This is what called as the hypothesis.
  3. Place a glass on the table for each of the fabric, which you had planned to test. Add one more glass, which can be used as a control for your experiment. This glass gets water with the same temperature as that of the other glasses, but does not gets wrapped in fabric.
  4. Fill each of the glasses with water reading about 98.6 degrees Fahrenheit while inserting a thermometer.
  5. Wrap each of the glasses with the types of fabrics.
  6. Wait for 15 minutes. The kitchen timers can be used to countdown the time.
  7. Using thermometer the temperature of each glass should be tested.
  8. Then, Record the observations in your notebook. Make sure you will get the answers to the questions- Did any kind of fabric used around glasses had increased the temperature of the water? Did any fabric decrease the temperature of the water? Did any glass hold a 98.6 degree Fahrenheit temperature throughout this experiment?

You observed that the Fabrics such as wool and the fleece behave as great insulators that can keep your body warmer over a period of time. On the other end, the fabrics such as lace &  cotton do not holds the heat well and do not keeps your body warmer for a longer period of time.

Conclusion – To get insulation means to make use of the materials, which allow least quantity of heat to get escaped. The wool fibers are said to be woven in a tight manner and will be thicker than that of the other materials like cotton. They do not allow much of heat to get escaped, hence they are known to be great insulators.
