Insulation Materials Investigation
Students test the insulation properties of different materials by timing how long it takes ice cubes to melt in the presence of various insulating materials. Students learn about the role that thermal insulation materials can play in reducing heat transfer by conduction, convection and radiation, as well as the design and implementation of insulating materials in construction and engineering.

Engineers, architects and contractors take insulation into account in the design and construction of any building. Engineers create materials that prevent the transfer of heat by conduction, convection and radiation in order to keep cool things cool or warm things warm. We don't want the cold air sneaking into our homes in the winter, and we don't want it escaping in the summer! These materials are installed in homes and other buildings to help lower the energy costs of heating and cooling. Engineers also design thermal insulation for countless other products and purposes, including pipe insulation (so water does not freeze in the pipes or heated water does not lose heat), handling food and beverages, space travel, and even your clothing!
After this activity, students should be able to:
- Describe the purpose of insulation materials as they relate to heat transfer.
- Describe the basic attributes that are common to insulation materials.
- Describe how engineers make decisions about insulation materials.
