Introduction

Insulation slows the flow of heat. Cotton, down, nylon, polypropylene, orlon, silk, and wool are some of the many insulating materials used in clothing. In this experiment, you will compare the insulating properties of cotton and wool using athletic socks. You will also study the effect of water on the insulating properties of cotton.

Objectives

In this experiment, you will

  • Measure temperature.
  • Calculate temperature changes.
  • Make a bar graph.
  • Compare the insulating properties of cotton and wool.
  • Investigate the effect of water on insulation.
