Igloo Math

Winter has come to Wisconsin late, but I could not be happier that it is finally here. This last weekend we got hit with a few good inches of heavy, wet powder. The snow has clung to everything like thick sugar icing; the trees, barns, and houses all look like some picturesque postcard of the great white north. For one day, we had perfect packing snow at the school and I used it to create a … ahem … math lesson. We built the first igloo of the year.

Using a 6-foot ceiling as a radius, we figured out that it would need to be 12 feet in diameter. Using pi we figured out how many rows of 8-inch bricks it would take to clear the arch — 21 rows. Then the building began. We managed to get the walls five and a half feet up before a few weak bricks (which I suspect were packed by another class, less dedicated to the cause) resulted in wall failure. The next day, the temperature dropped to 14 degrees at noon, and our bricks were as hard as glass. There would be no new bricks.

We re-used them to build 2 smaller igloos, going around in circles and eventually walling a student up inside (hopefully one who is not claustrophobic) and digging out a door. Add a little water to the walls and they become incredibly strong. Other teachers might play football at recess or take kids out to the pond for skating. I build.
