• Chose a building material
• Decided to work alone or in a group
• Built blocks out of dough or ghost gum
• Let them dry or harden
• Chose a material to join the blocks

• Some of our igloos collapsed
• Some were fragile and broke
• Some of us had to use supports inside to try to build the igloo
• The blocks were the wrong shape
• These blocks when piled on top were good for building a tower, shape not a dome
• We couldn’t make our igloos stand without resorting to a glue gun

^{Building an igloo is not as easy as it looks!!}

• The material is very important – the Inuit like certain snow conditions and a good site
• The blocks need to be the shape of a domino, not a square
• The building material needs to be soft enough to cut and trim the blocks
• The laying of the blocks needs to start with a few wedge shaped blocks
• The blocks need to spiral
• There is a "keystone" block to finish the roof
