Gas Mask
Ypres, Belgium 1915 the Germain army used a form of chemical warfare called chlorine gas. A physicist by the name Cluny MacPherson invented the respirator or gas mask to combat this new warfare. the gas mask consists of metals and fabric. -
Lewis Light Machine Gun
this gun was used in world war 1 by Canadians. this gun was more effective as it was huge firepower. the LMG made Canada more effective and it was also portable. invented in 1913 but used by Canadians in 1916 onward. -
Sonar
sonar technology invented in 1917 was invented by Robert Boyle. the use of sonar technology allowed ships to detect submarines and U-boats. allowing the Canadian navy to have a head over enemy subs. -
Hydroelectricity - Ontario Hydro’s Queenston-Chippawa power generation project
Identified as the world’s first hydroelectric project, and considered the largest development of its time, the Queenston-Chippawa development proves its historical significance from its extensive power supply to Canadian cities between 1917 and 1922. Chaired by Sir Adam Beck, this development lives on in Canadian history as it was renamed the “Sir Adam Beck Generating Station.” -
The Variable Pitch Propeller – Wallace Turnball
Invented by Wallace Turnbull in 1922, the pitch propeller transformed aircrafts in such that this propeller made flying in angles possible due to the propeller’s innovative blades. This invention shaped the future of our aircrafts in our plane’s designs and pilot’s control in flying planes. -
Insulin invented by Frederick Banting, Charles Best and James Collip
Also in 1922, was the invention of insulin by Frederick Banting, an orthopedic surgeon, as well as his assistants Charles Best and John MacLeod. This invention was deemed significant of its time given the long-lasting controversy regarding the discovery of insulin. This paved the way for our current and several treatments for diabetes. -
Arthur Sicard invented snowblower
Immediately after the invention of the first powered snow machine, came the invention of the first snowblower, invented by Arthur Sicard in 1925 in Montreal, Canada. It was Sicard’s ambition to aid farmers in clearing snow from their fields to feed cows that drove this invention. -
Battery-less Radio/AC Tube
Edward Rogers created a tube that allowed home phones to be battery-less. while doing this he also caused the sound these devices made to be almost completely silent. the revolutionary invention changed home communications. -
Continuity and Change (Snowblower)
In 1894, Sicard was inspired to invent a snow blower; however, it took him 31 years until actually inventing it and running it for the first time in 1925. This demonstrates continuity whereas his mere invention of the snowblower demonstrates change over time. -
Continuity and Change (Snowblower) part 2
We see that snowblower are no longer produced in large sizes to accommodate fields, but also smaller sizes that are more convenient for everyday use such as removing snow form a driveway or sidewalk. However, continuity stands until today because we still use the snowblower as opposed to an alternative invention to remove snow. -
cause and consequence (hydroelectricity)
Hydroelectricity is an amazing resource and the Queenston-Chippawa built-in 1917 was the biggest and most powerful of its time. This hydroelectricity plant construction caused many cities in Ontario to expanded outwards into the country. in addition to the cities being expanded many new cities were built and lots of new town communities were constructed after the building of this hydroelectric plant. The power of this plant allowed many cities and towns to use it and improved Ontario's economy.
