Igloos Research Paper

Many people know about igloos. These icy forts have been constructed by Eskimos for centuries. Many people ask, “ How are igloos built? How have they changed? How come they don’t melt with a fire near by?” Well, I am here to answer all of your questions.
How are igloos built? To build an igloo, Eskimos only need one tool: a snow saw or a large knife. First, they find an area with a lot of dry, hard-packed snow. The Eskimos then start to make heel prints to mark the circular pattern of the igloo. After they do that, they start to cut the ice in the middle of the heel print ring, this will form the low floors in the igloo. Once the first ring of blocks is in place, the Eskimos will cut a long slope descending down some of the blocks. The blocks then start to form a continual spiral pattern going up. Putting in the last few blocks is tricky, if put in wrong it can collapse. After the last block is in place, the Eskimos cut a tunnel so they can get in and out. Once out, they go around the igloo and pack in holes and cracks with snow. Finally, they put their things in and use a big snow block to cover
Not many people know how igloos have changed, but they have changed in many ways. For example, the word ‘igloo’ originates from the Inuit word ‘iglu’. Also, the large knifes the Eskimos use were originally made from bone, but as traders came in they got iron ones. Igloos were once used all the time by the Inuit as temporary homes to follow herds of animals, and they still are! But now, the women and children don’t have to live in igloos while the men are out hunting. Instead, they live in villages.
How does a fire not melt in an igloo? Actually, it does! When a family moves into an igloo, their bodies bring heat along with the fire. If the family puts out the fire and leaves for a while, it gives time for the walls to freeze again. So when the family returns, their house is nice and cold for them to come back
