What materials work best for cold weather?Copyright U.S. Department of State http://www.state.gov/r/pa/ei/pix/b/sat/80200.htm
In this design activity, students investigate materials engineering as it applies to weather and clothing. Teams design and analyze different combinations of materials for effectiveness in specific weather conditions. Analysis includes simulation of temperature, wind and wetness elements, as well as the functionality and durability of final prototypes.
Engineers have the important job of designing materials for clothes so they meet specific weather conditions. For example, in 1976, Robert Gore created Gore-Tex fabrics, which are now widely known for their applicability for outdoor activity clothing. Gore-Tex offers protection from wind and rain, but is breathable at the same time, allowing sweat to escape via evaporation. Materials engineers also develop textiles that resist wrinkles, stains, odors, are more durable, incorporporate electronics, and are suited to a human health and safety on Earth and in space.
After this activity, students should be able to:
- Explain the importance of materials engineering for survival and comfort in various weather conditions.
- Describe several examples of engineered materials and textiles.
- Model and analyze different materials for the effectiveness to resist wind, water and cold temperatures.
- Describe and understand the steps of the engineering design process.
