A large loudspeaker called the Oscillator was lowered into the water while attached to a ship. It was a hollow, 1,200-pound cylinder encased in wires that vibrated rapidly and made a loud pinging sound. The system used a focused microphone to tune frequencies to receive signals that were sent.]]> 2023-02-28 18:17:18 UTC https://padlet.com/341050748/za1ouwshi5klo7db/wish/2498407881 341050748 https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500239441 The first gas mask, named the hypo-helmet, was created by Captain Cluny Macpherson. The original gas mask was a bag that has been chemically treated and was designed to be worn by soldiers over their heads.

Its design was altered to make it easier to manufacture and transport. The mortar could fire its shells anywhere between 100 to 600 yards. The use of mortars to fight against German forces had a significant impact on Canadian war history.]]> 2023-03-01 22:31:58 UTC https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500245040 341050748 https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500255992 Isaac Newton Lewis created the Lewis Light machine gun, a highly effective and widely utilized weapon that was mostly used throughout the duration of the First World War. It was a remarkable weapon that could fire 500–600 rounds per minute. It was a significant technological advancement for Canada and many other countries since it made it easier for Canadian soldiers to kill enemies and win in battle.]]> 2023-03-01 22:48:24 UTC https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500255992 341050748 https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500257412 Although it was still in the early phases of development, Ray H. Muscott submitted the first snowmobile patent in 1915; as a result, Joseph-Armand Bombardier is frequently credited as the "creator of the snowmobile". Despite the fact that the idea was created in 1915, Carl Eliason creation of the machine in 1922, which used a motorized propeller to advance was more revolutionary in Canadian history.]]> 2023-03-01 22:50:31 UTC https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500257412 341050748 https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500261647 Due to their discoveries of insulin, Dr. Frederick Banting and Charles Best became ground-breaking icons in the medical field. On July 27, 1921, they began experimenting on dogs at the University of Toronto, where they conducted their research. The first human tester tried it out on January 11, 1922. The first human test subject who received it in the hopes of curing diabetes was Leonard Thompson, a 14-year-old kid at the time. Although Leonard experienced an allergic response after receiving the first dose, the second treatment, which he received 12 days later, went much more smoothly. This proved to be a significant advancement in the field of medicine.]]> 2023-03-01 22:56:57 UTC https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500261647 341050748 https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500268466 In 1925, Arthur Sicard created the snowblower in Quebec.  The initial model of the machine was named the "Sicard Snow Removal Snow Blower." The snow would be scooped up by a scooper in front of the car, and then it would be sprayed onto the side of the road by a fan. The snow could be launched up to 27 metres in distant by the fan. The snowblower was a very remarkable Canadian creation that is now widely used in the wintertime all over the world.]]> 2023-03-01 23:07:50 UTC https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500268466 341050748 https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500286593 Two of the oldest and biggest railway firms in western Canada received authorization to begin building a railroad in 1880 that would run parallel to the waterways leading to Hudson's Bay. After reaching 64 kilometres in 1883, the two corporations combined their projects. T hey were forced to divert from the original course due to political and economical considerations. Although work progressed slowly, the railway was eventually finished and officially opened on September 10, 1929. Before Manitoba's resource discoveries, the $45 million railway was viewed as a failure. The Hudson's Bay Railway, which is still in use today, was a significant technological advancement in Canada's trading and exportation business throughout history.]]> 2023-03-01 23:38:59 UTC https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500286593 341050748 https://padlet.com/341050748/za1ouwshi5klo7db/wish/2500286867 In Canadian history, the Hudson's Bay Railway is a prime example of cause and consequence. Although the railway was established in 1929, the Canadian government became heavily committed to it due to a number of reasons, including the transportation of people and supplies. The two biggest Canadian businesses were given permission to construct a track that ran parallel to the Hudson Bay Waterway in 1880. Building the railway was something that both of the two businesses that the Canadian Northern Railway were motivated to do. It had both negative and positive effects, despite being a revolution for the Canadian economy. The establishment of worker rights was the first obvious effect of the Hudson's Bay Railway. Workers were lured into camps during the early stages of construction with promises of a decent lifestyle that included wholesome food and a comfortable place to live, but these assurances were untrue. In addition to being paid 20–30 cents an hour, workers were also required to pay $1 per day for housing and transportation to and from the camps. Poor living and working circumstances led to the hospitalization of workers for blackflies and mosquito bites as well as deaths from the cold. Workers' rights were given a lot of attention as a result, and they would go on to play a huge role in modern society. The expansion of the economy was the second major and obvious effect of the Hudson's Bay Railway. The Canadian Pacific Railway "was using its control to demand high shipping rates" for farmers to transport their crops to markets, so the Hudson's Bay Railway was first created to avoid these extra charges. Upon its establishment, the Hudson's Bay Railway was used to move a wide range of goods, including metals and minerals, as well as lots of tourists who wished to see the North. The Hudson's Bay Railway significantly influenced Canada's economy and effectively demonstrates cause and effect in Canadian history.

Although being created in 1925, it has developed and is still widely used today. Although Arthur Sicard created the snowblower in Quebec in 1925, its primary function has remained the same ever since. The snowblower was initially created by Arthur Sicard to facilitate his daily milk deliveries during the winter by clearing the snow in front of the vehicle and shoving it to the side of the road. The car still serves the same broad purpose today, even after 97 years. The snowblower was invented to make it safer for people to travel in cars throughout the winter. Since so much of our society depends on cars now, the snowblower has remained popular throughout the winter. The snowblower has undoubtedly changed throughout the history of its existence, but it continues to share elements like a scooper and a fan up front or a thrower that tosses the snow. The snowblower has always been incredibly helpful for people all around the world, even though it has evolved from a driven vehicle to larger, more efficient vehicles and machines that are pushed. Because of this, the snowblower is a fantastic illustration of historical continuity and change.
