Experiment #19 from Exploring Physical Science

Education Level
Middle School


Insulation slows the flow of heat. Cotton, down, nylon, polypropylene, 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 socks. You will also study the effect of moisture on the insulating properties of cotton.


  • Use two Temperature Probes to measure temperature.
  • Calculate temperature changes.
  • Make a bar graph.
  • Compare the insulating properties of cotton and wool.
  • Investigate the effect of water on insulation.
