Dream Big Special Features
This series of special features may be used to provide enrichment to Dream Big and include behind-the-scenes videos and educational webisodes on engineering topics.
This film highlights the many ways in which engineers tackle problems big and small and explores how the principles of engineering can create a better future for all. Three female engineers are specifically profiled: one who specializes in creating structures that can better sustain earthquakes, ...
Fall Comes to Lac La Ronge
Fall Comes to Lac La Ronge is a 15 minute video produced by Randy Johns and Richard Frisky for KCDC. It details the cycle of the seasons as they slowly transform from the glory of summer to the splendour of fall. How various life forms prepare for fall is highlighted, including the migration patt...
Earthquakes. The Horror and the Science
Series: News in Review: April 2010
In late February, an earthquake strikes Chile killing more than 800 people. Two months before another earthquake kills more than 220,000 people in Haiti. Why did so many more die in one country and what makes the earth move?
Geologists search for clues of massive tectonic shifts that reverberate through the continent, forcing the mountains up out of the plains. Bends and cracks reveal the growth pangs of the mountain building era.
The Great Lakes
This episode tells the story of the changes in the geology and landscape of the vast central area of North America. In recent geologic history, five interconnected freshwater lakes are formed. We explore a long vanished mountain range, the remains of a tropical salt-water sea and trace the story ...
The Canadian Shield
Geologic time has shaped the Canadian Shield into a complex ensemble ranging over millions of square kilometres. The geography of the Shield has been surveyed from North to South, and yet its underground world still leaves much to be explored. The Canadian Shield is one of the last frontiers of h...
The Atlantic Coast
This episode tells the story in three dramatic chapters of how tectonic upheaval pummelled and pounded eastern North America until the shape we recognize today finally emerged. The discovery of fossils provides proof of how North America and Africa were once bound together. Tectonic movement lies...
From studying the sediment deposits at Anticosti Island, to rebuilding the history of one of the most significant mass extinctions (443 million years ago), scientists are piecing together elements that continue to shape this diverse region. Scientists reveal the fractures in this active earthquak...
