Baggie Mittens

Figure from experiment 3 from Elementary Science with Vernier


Humans create their own body heat by eating and then converting food and body fat into other forms of energy, including heat energy. Our bodies are also affected by the temperature of our surroundings. In a process called conduction, heat always travels from a warmer area to a cooler area. Sometimes our body is the warmer area; sometimes it is the cooler area.

This effect of the external temperature explains why we wear different types and amounts of clothing in different seasons. To minimize the loss of heat from our bodies during the winter, we wear warm clothes and lots of layers. To help us eliminate heat from our bodies in hot weather, we wear clothes made of light, thin material.

Insulators minimize the flow of heat from warmer areas to cooler ones. The better the insulator, the less the temperature will change over a certain time period because it takes longer for the heat to be conducted through the insulator.


In this activity, you will

  • Compare mittens made of plastic baggies containing different types of insulation.
  • Determine how long would it take for a person's hand to get cold wearing different kinds of mittens.
  • Use graphs to get information about the different materials' performance.
