Mr Frost came into our class and talked about how we keep warm. Mr Frost talked about hypothermia. You can get hypothermia when you sweat because the sweat is like water and water cools your body down quickly. Mr. Frost talked about how you should keep warm by having many different layers of clothing. He went from undershirts to heavy duty jackets. First you wear an undershirt made of material that absorbs sweat from your skin like polypropylene or silk . Next you wear wool to insulate you and keep you warm. Then you wear a wind breaker to block the wind. Finally, you wear a waterproof and warm jacket.
Mr Frost told us that it has to really cold to get frostbite (-40 or so). Mr Frost said that when you get frostbite your skin turns white and that the blood tries to stay in the core of your body. Frostbite starts in your hands and ears. You can loose fingers or toes or part of your ears when you get frostbite. You could also die from frostbite.
We had a lot of fun listening to Mr. Frost. We are very thankful he came to teach us and we now know how to stay warm and safe outside in the cold.
