Module 6: Surface Area

 

Lesson 1: Area and Surface Area

 

Focus

 

The bark canoe was first used by First Nations people across Canada. This canoe was well suited for travel on lakes or rivers. The crafts were later used by voyageurs to transport furs and other goods between trading posts during European exploration of North America. The basic design was lightweight and manoeuvrable, yet the canoe was sturdy enough to carry heavy loads. The canoe's basic design has stood the test of time.

 

There are still a few dedicated canoe artisans who follow traditional construction techniques. In the photograph, the birchbark cover is carefully stitched together. The amount of bark needed depends on the canoe’s surface area.
