First world war (1914-1918)
Many countries were involved in this war. The main ones were Russia, USA, China, Italy, Japan, Canada, Australia, India and South Africa. About 172,000 were injured and 66,000 fatalities. When Britain went to war at the beginning of August, Canada, Newfoundland and other colonies and dominions of the British Empire were automatically at war. The outcome of this war was Great Britain and their allies were victorious and Germany had a big loss. The allied troops created a peace treaty with Germany. The allied troops created a treaty called the Treaty of Versailles. They created this to end the war.
Russian civil war (1918-1920)
Countries that were involved in this war include Russian SFSR, White movement, France, United Kingdom, USA, China, Italy, Japan, Canada, Australia, India, Poland, and Czechoslovakia. 14 people were killed and 22 injured. In February of 1918, Russia and Germany sign the Treaty of Brest-Litovsk which gave Russian land to Germany in exchange for Russias exit out of WW1. The Soviet Union became the new Russian power.
Second world war (1939-1945)
The main nations involved were USA, Russia, France, Britan, Canada, Germany, Italy, and Japan. On September 10th 1939, Canada declared war on Germany. In December 7500 soldiers arrived in Britain. On September 10th Jun 1940, Canada declared war on Italy. 1.1 million Canadians served in the Army and more than 44,000 lost their lives and 55,000 were injured. The outcome of this war was Germany was taken down by the Soviet Union. Germany and its capital Berlin were divided into four parts.
Korean war (1950-1953)
Countries include South Korea, North Korea, China, Soviet Union, United Nations, USA, United Kindom, Australia, Belgium, Canada, France, Colombia, Greece, New Zealand, South Africa, Thailand, Turkey, and Ethiopia. 516 Canadians were killed and about 1020 were injured. 26,000 Canadians participated on the side of the UN, and Canada sent eight destroyers. The North Korea invasion and Chinese invasion of South Korea were forced away.
Persian Gulf war (1990-1991)
Countries involved include Kuwait, USA, United Kingdom, France, Canada, Egypt, Syria, Qatar, United Arab Emirates, Oman, and Iraq. No Canadians were killed. This war included 35 nations led by the United States against Iraq in response to Iraq’s invasion and annexation of Kuwait. This war was important in Canada’s military history. After this conflict, Canadians continued to serve in peacekeeping in the region.
All of these wars were a big part of our Canadian history.

Reactions
In our science class, we did a few experiments involving chemical reactions, equations and balancing them. The first experiment was with calcium metal and water. We were testing hydrogen gas. We used two test tubes and we had a flame. When the flame came in contact with the gas, it caused the flame to go out and made a loud popping noise. When the hydrogen gas and oxygen were mixed together it created a reaction, which concludes that it worked and we successfully tested hydrogen gas. Next, we were testing oxygen gas with hydrogen peroxide. The glowing splint caught on fire and also created a small popping noise. There was that noise due to how fast the heat and oxygen molecules reacted with each other. This experiment was successful in creating oxygen gas. The last experiment was testing carbon dioxide gas using carbonate and hydrochloric acid. When the flame went out when it came in contact with the gas. This was also successful because carbon dioxide takes away oxygen. The flame went out because it needs oxygen to keep burning but it came in contact with the carbon dioxide, which resulted in no flame.

Careers and Conversations Reflection
I had the opportunity to speak with many guests with various careers. I got to talk to 6 people, Sara Bynoe, Jessica Anderson, Vadim Egorov, Lindsey Jackson, Jessica Callergo, and Ken Britton. I really enjoyed speaking with everyone and learning about there jobs. Two people that inspired me were Jessica Anderson and Jessica Callergo. Jessica Anderson inspired me because of the variety of her job inspired me. She really enjoys her job because of the flexibility she has and how she does other jobs such as teaches yoga. I wasn’t very interested in her job but I liked the environment of her job that she explained. Jessica Callergo also inspired me because it was the job I was most interested in. She is a personal trainer that teaches people from all around the world. I am interested in sciences and the human body so this was one of the jobs that stood out the most for me. The soft skills required for this job would be being able to communicate with people. Hard skills would be to know the body and how to help your patients. I found the Careers and conversations morning a valuable experience because I liked hearing peoples opinions about their job. I would have loved for there to be more jobs I would have been interested in such as doctors, etc. I really enjoyed this experience.
Neurofibromatosis type 2
neurofibromatosis type 2
neurofibromatosis type 2 is a disorder which is growths of noncancerous tumors in the nervous system. The most common tumors associated with this are called vestibular schwannomas or acoustic neuromas. These growths develop on the nerve that carries information from the inner ear to the brain (auditory nerve). Tumors found along other nerves can also be found. Signs and symptoms usually appear in a person’s twenties but can begin at any age. Most common symptoms are hearing loss, ringing in the ears, and problems with balance. If tumors develop along other nerves, you can experience tumor growths which can change vision, numbness or weakness in the arms or legs, and fluid buildup in the brain. Symptoms vary on the location of the tumor.
Estimated 1 in 33,000 with this worldwide.
Mutations in the NF2 gene cause this disorder. The NF2 gene provides instructions for a making a protein called merlin (schwannmin). It is a protein produced in the nervous system. Merlin asks as a tumor suppressor, it keeps cells from growing and dividing too rapidly. Mutations in the NF2 gene lead to the production of a nonfunctional version of the merlin protein with allows cells to multiply too frequently and form tumors.
This disorder has an autosomal dominant pattern of inheritance. People with this condition are born with one mutated copy of the gene in each cell. In about half of cases, the altered gene is inherited from an affected parent. The remaining cases result from new mutations in the NF2 gene and occur in people with no history of the disorder in their family.
To have this, two copies of the NF2 gene must be altered to trigger tumor formation, But most other autosomal dominant conditions only need one altered copy f the gene in each cell to cause the disorder.

Scientific Method Bubble Gum Lab
Conclusion:
Our two hypothesis ended up having opposite results, Gum A resulted in a bigger bubble size but Gum B had more of an ability to stretch. Our first hypothesis was for what brand of gum will be the best at blowing bubbles. “If we chew both pieces for 3 minutes each, then Gum A will blow bigger bubbles because it is thicker” We then tested both brands and recorded our data. We recorded 3 trials for each piece of gum. The average size bubble for Gum A came to 10cm and Gum B came to 3.25cm. We concluded that Gum A was the best at blowing bubbles because it was thick and did not easily break. Our next hypothesis was for gum stretch ability. “If the gum is stretchy then the bubble will be bigger because it will not easily break” Our data showed that Gum B had more ability to stretch. When we tested its ability it stretched to 130cm and Gum A stretched to 49cm. Gum B was able to stretch more in part 2 of our experiment because it was more of a stretchy texture oppose to Gum A which was thicker. Since Gum A’s texture was thick, it made its ability to stretch harder and it didn’t stretch as far as Gum B. When blowing bubbles, Gum A was the best since its texture was thick and didn’t break easily. I think our hypothesis should be refuted because of the opposite results. The 5 variables listed below could have affected our results greatly.
Some variables that may have affected our outcome of this experiment:
- The number of times the gum was chewed by each person in 3 minutes. If it’s not the same, it can affect the results.
- Having different chewing techniques (speed, etc.)
- The speed of pulling in part 2. The person could have been walking back faster while testing Gum A than Gum B
- Ability in blowing bubbles
- More tests with part 2. We could have averaged it and found a better answer.
Qualitative: Our observations to help write our hypothesis and conclusions.
Quantitative: Recorded our data of the size of bubbles and the length the gum stretched using table graphs.
SI units: There were SI units used in this experiment, centimeters, and grams. We used centimeters to measure the size of the bubble and the length the gum stretched. Also used grams to weigh the gum before we began.
