Build a Prototype Igloo

We cannot build a real igloo but we would like you to build a small ‘prototype’ from sugar cubes. This would help us to know how many snow bricks we might have to cut for a real one!
 
 
Building

• You must build your prototype on a piece of white A4 card.
• The circular base of your prototype igloo must be no greater than 10 cm in diameter.
• The entrance doorway must be no higher than 3 cubes.
• You may build a tunnel entrance to your igloo.
• You can only use the sugar cubes in your box.

 
Recording Information

• Estimate how many sugar cubes you think you will need before you begin and keep a record.
• Keep a record of exactly how many sugar cubes are in each layer of your igloo.
• Keep a record of exactly how may sugar cubes you use if you add a tunnel entrance.
• Calculate the total number of sugar cubes you used altogether.
• Present all your information in a table or chart.
