Three-dimensional models, made to scale, serve a variety of purposes. These purposes vary from engineering and design to the amusement of people. Have you ever wondered how they put those perfectly proportioned ships in bottles?

 

Most scale diagrams or models you have examined have been much smaller than the original items. Do an Internet search using the keywords “NAIT Avro Arrow video.” Watch the video to see how students from the Northern Alberta Institute of Technology (NAIT) in Edmonton helped restore a much larger model of the Avro Arrow. This plane is a proud part of Canada’s aviation history.
