  • Heat
  • Cooling rate

About the Lesson

Your company designs and manufactures extreme outdoor clothing and equipment. Your project manager wants you to investigate insulation materials that can be used to design new products for the company. The insulation material that you recommend will be used in containers to keep food hot or cold and for cold weather sleeping bags and clothing. Your task is to determine the best insulation material for the products and to support your conclusion with test data.

As a result, students will:

  • Students will engineer and build a simple thermos that will keep an object warm when submerged in an ice bath.
  • Students will use appropriate technology to evaluate their design, collaborate with colleagues and present their findings.
