This project provides students an opportunity to model their bridge designs from known examples, test their prototypes and amend their designs. It also offers cross-curricular learning of STEM-based concepts like gravity compression and tension.
If the bridge is being used for a Skills Canada Competition, note the following specifications: The bridge must be a minimum of 50 mm wide, 100 mm high and span a gap of 500 mm. In the competition, bridges are weighed and it is the lightest bridge that can hold a mass of 1kg for 60 seconds that will win.
Since 1994 Skills Canada British Columbia has worked with industry, educators, government and labour to promote rewarding and in-demand skilled trade & technology careers to BC’s youth. Widely recognized for its annual competitions hosted in communities throughout BC, Skills BC engages over 35,000 students annually in its regional, provincial, national and international competitions each year.

Procedure
-
Research different bridge designs online or use local examples
-
Sketch design, ensuring that the total length will span the gap with enough extra on either end to sit securely on the supports.
