Igloo building

Ice-cold master builders

Upon arrival at the 'construction site', teams begin the tricky creative task of building their igloo village. The snow 'bricks' are first cut from a snowpack which has been specially prepared by a snowplough machine. These blocks are then systematically arranged in a circular pattern and with each layer, the dome becomes steeper. Have you calculated accurately enough for the structure to hold its shape? How would you compare to the Inuit?
