I was sent the following question by a third grade friend of my daughter's and need help to answer it. Dear Mrs. Wynn, My class and I want to know why some people in the Arctic use snow to help keep them warm. For example, they might take off their mitten, rub snow on their hands, and put it back on. If you know please contact us. -Thank you. From, Anastasia in Mrs. Hartman's class. Apparently this behaviour was shown in a Discovery Channel special recently and they read in Balto that the mushers rub snow on the dog's paws if they get wet, otherwise their paws will freeze and they will never be able to walk again. I thought maybe the very cold snow actually dried the paws (hands) as the moisture would freeze to the extrememly cold and dry snow and therefore be removed with the snow as it was rubbed off. I look forward to your reply Emma Wynn
