Here's another book recommendation - CENTURY OF SERVICE by Donald Graves, published this year by Robin Brass Studios. It is the regimental history of the South Alberta Light Horse, but contains an excellent section on World War One that explains the entire Canadian participation in the war on the ground (doesn't touch on the navy or the air services, though Canadians were very prominent there, too).
Rather than reading about Newfoundlanders getting machinegunned in droves, check out p 165. "In 1918, Brigadier General Raymond Brutinel's Independent Force, highly mobile and commanded by radio, was one of the most advanced combat formations in the world." Brutinel is mentioned in Pierre Berton's Vimy, and the Canadian Motor Machine Gun units were technologically and tactically advanced and sophisticated. More interesting, to me, then the oft retold stories of senseless slaughter that Canadians like to wallow in.
By 1918, Canadian soldiers were using many if not most of the techniques that would make the German Army so successful in 1939-40, including infantry divided into small squad-sized groups of 10 men or so, the use of wireless (radio) to communicate, the co-ordination of supporting fires from artillery and machineguns, and even the use of tanks and armoured cars. One of the few things the Canadians didn't have that the Germans did in 1939 was armoured troop carriers - and these were extremely rare in the German Army throughout the war.
An interesting assignment at a university level would be to compare the Canadian Corps in 1918 to the German Army of 1939.
As for high school (?) Social Studies, a look at that book would be most interesting and you will get an appreciation of what Canada did, at least from the perspective of the Army. Graves is one of our best living historians - and holds his own against our dead ones, too. ;D
The WW I sections centre on an infantry battalion (the 31st) and a cavalry unit (Alberta Dragoons, later Canadian Light Horse), the latter of which served from 1915 to 1918. Very well written, not a lot of "scholarly" words (ie isn't written at a university level so is rather accessible), and incorporates a lot of personal vignettes and stories to keep the story rolling. Trouble is, it is expensive and esoteric enough that might not be easy to find in public libraries.
