Tungsten, 74, Waterloo-Wellington Science Engineering Fair, Waterloo ON

Tungsten: This tile combines aspects of the element tungsten with the Waterloo-Wellington Science and Engineering Fair (WWSEF) which was founded in 1974. The W symbol for the element comes from wolfram, the name of the element in many European countries; tungsten was first extracted from the mineral wolframite. Each year the 350 young researchers and innovators who exhibit their projects for our 120 judges begin with bright ideas, hence the light bulb with the tungsten filament. Tungsten is considered robust, just like we've been for 38 years.

The tile is the creative and technical work of Eddie Kim — now at the University of Guelph — a multi-year gold medalist at the WWSEF and competitor at the Canada-Wide Science Fair
