People are able to survive in the cold of Antarctica if they wear the right kind of clothes.
Explain that clothes insulate by trapping body heat. Thus, you stay warmer because your body keeps making heat and your clothes help to hold the heat near your body. Sometimes if you are very active, there is so much heat you feel hot with all your layers of clothes, even if the temperature around you is -20 degrees. Sponsored by the National Science Foundation, our trip was to encourage kids' interest in science and Antarctica. Randy and I were able to survive in the frigid environment because we did not stay outdoors for long periods of time and because we wore layers of clothes and special footwear.
