Development of the hydrophone
In 1914, a device was developed called a hydrophone. The hydrophone was used inside of submarines by the crew so they did not collide into icebergs. This machine was very effective and helped lower the risk of damaging and sinking ships with valuable goods such as food, ammunition and weapons. Canada would use a hydrophone to detect icebergs so that they could avoid them and make sure their supplies were safe. -
Lewis light machine gun
The Lewis light machine gun was supplied straight to the Canadian troops during World War I. The gun was quite expensive costing 256 Canadian dollars. It was well worth the price because it was a very reliable gun with a 47 round magazine that didnt overheat or jam very easily -
Invention of machine guns on planes.
During World War I Canada decided to mount machine guns onto the front of planes, right behind the propeller. They created a mechanism that synced the bullets opposite with the propeller so the machine gun wouldn't shoot through the blades. Before this pilots would arm themselves with projectiles to throw over side of the plane onto enemy territory. -
trench mortars
A trench mortar was a short and stumpy tube created to fire projectiles at a steep angle so that whatever was being shot out would land directly down on enemy territory. A great advantage of the mortar was that it could be shot from the trench and not do damage to the trench and you would be covered and not in plain sight. Canada supplied their divisions with mortars to be used in the trenches to launch bombs into enemy trenches. -
depth charges
Depth charges are a bomb like mechanism that would be dropped into the water by boats on the surface and detonate at a certain depth. They were created by a man named Herbert Taylor and they were used in WW1 to create leaks in submarines and force them to come back up to the surface and later be shot or hit by boats that were ready on the surface. -
depth charges pt 2
Depth charges were responsible for destroying around twenty submarines. Canada used these on their boats to protect themselves from any incoming enemy boats. -
mustard gas
During World War I, a gas called mustard gas was used to attack soldiers on the battlefield. It was first introduced in the early stages of WW1. Mustard gas causes severe burning of the skin, eyes and respiratory tract. Mustard gas can be absorbed into your body by inhaling it, ingesting it, or coming in contact with the skin or eyes. Canada developed this gas to try and use it tactically against their enemies -
developments in grenades/bombs
multiple variations of hand grenades also known as bombs (to the British), started appearing throughout the war with Canada. Canadian infantry platoons had a section of specialists hand grenadiers and rifle grenadiers. During the summer of 1918, the Canadian infantry were equipped with experimental weapons known as anti-tank rifle grenades. These special marksman would use these weapons in the trenches and would fire them into no mans land and enemy trenches -
echo ranging systems
Echo ranging systems were used in the water to detect enemy submarines and boats. They created this by using a quartz crystal and placing it in between two metal plates and it would create a sound. For the first time in late 1918 echoes were heard by a submarine over 1500 m away. When Canada would ship their munitions to europe they would use an echo ranging system to detect boats and submarines in the water for safety -
discovery of insulin.
On the day January 11th, 1922 insulin was first used to treat diabetic patience. It was discovered by “Sir Frederick G Banting, Charles H Best and JJR Macleod at the University of Toronto”. Fun fact, a bottle of insulin can be found on a Canadian bill. -
development of the respirator
After the battle of Ypres, where Germany released a toxic poisonous gas known as chlorine gas on the 1st Canadian division, Canadians decided to start equipping their troops with respirators to limit the effect of tactical gas especially after what happened after The Battle Of Ypres. This helped Canada fend off the use of tactical gas against themselves. -
cause and consequences event 1,2
Canada needed a new way of attacking other countries in war and a more efficient way of doing it, so we developed a mechanism that we could mount on planes that shot at enemies. It helped us come up with a new way we attacked our enemies, but the consequence was that other countries adopted this technology and used it on us. -
cause and consequences pt 2
The same way the machine guns helped us and were also negative was the development of hand grenades and rifle grenades, it helped us attack other countries but it also gave them a way to attack us. -
Continuity and Change events #3 and #7
With the development of mustard gas, it changed the way we used chemicals in war and the different possible ways of attacking enemies. It also made us adapt to this source of weaponry and forced us to learn how to overcome it. -
Continuity and Change events #3 and #7 pt 2
Once mustard gas was developed we had to prepare our troops for it and we needed to change the way we sent our troops to war and how we prepared them for these types of attacks. We had to find a way around the gas so we developed respirators and gave one to every soldiers so they could be prepared.
