Surface Area of a Sphere OE2018

The formula for the Surface Ares of a sphere is 4 x Pi radius squared (4πr2)

For this activity we had to cut an orange in half, which created 2 hemispheres. We then had to peel off the outside, and place the orange peels into the traced circles. This then showed us that 4 circles can be filled which gave us the formula. I learned a new formula, and thought this was a super fun way to discover new formulas and learn how to calculate the Surface Area of a sphere.

Garibaldi Lake Task

For this assignment we had to figure out how much water the barrier at Garibaldi Lake holds, and what would happen if the barrier broke.

To find out how much water is in the lake, I had to calculate the volume. From the dimensions on Wikipedia, the surface area of the lake is 9.94km squared, and the average depth is 119m. So first I have to convert 9.94km squared into metres squared.

9.94km squared = 9 940 000 meters squared.

So then I had to multiply 9 940 000 x 119 to get a total of 1 182 860 000 meters cubed.

I wanted to figure out the volume of Garibaldi Lake, so I needed 1 182 860 000 metres cubed to be converted into Litres.

So 1 182 860 000 meters cubed = approximately 1 trillion Litres.

So the volume of Garibaldi lake is approximately 1 trillion Litres.

1 Litre is equal to 1 kilogram. So Garibaldi lake flowing out is around 1 trillion kg. A skyscraper weighs approximately 222500000 kg. So 1 000 000 000 000 divided by 222500000 = 4 494…. Now imagine 4 494 skyscrapers falling down on you. That is how much weight it would be if Garibaldi Lake flowed out.

If the barrier at Garibaldi Lake were to break, a huge portion of the 1 trillion Litres would flow down into Squamish and flood the surrounding area. Because the lakes floor is not flat, there are parts that are deeper than the barrier, so if the barrier were to completely break, the deepest parts of the lake would not flow out. After doing some research, I found out that Steve Quane did a study on Garibaldi lake and found out that the energy of the lake flowing out, would be 200 times more energy than the atomic bomb dropped on Hiroshima. That is a really scary thing to think about, and because we live so close to this natural danger, it is a threat that needs to be assessed often to make sure that it is safe and that there is not a high risk of the barrier breaking.

RAC 2018

This week it is Random Act of Caring week, and I chose a RAC to demonstrate throughout the week. I chose #20 – Talk to a shy person who is by themselves at a social event.

In my church youth group, we have a new girl who just started attending our youth group. She came into the Youth room, and looked very shy, and didn’t know anyone. I saw that she was alone, so I went over and started talking to her. She looked very happy when I started talking to her, because she wasn’t alone anymore. I continued to talk to her for a while, and when it was time for our youth group to play a wide game, it was in partners, so I asked her to be my partner so she wouldn’t be left out. She was super grateful, and even said to me “thank you for being my partner, because I don’t know anyone else.” I felt very good for being kind to her, and she said that she is going to come back to our youth group again next week, so I hope we can become friends.

What did you notice about the people who benefited from the RAC?

– I noticed that she was very happy for my company, and was thankful that she now new someone at the youth group. I also noticed that because I was kind to her, she was kind to everyone else, and so they were also kind to her.

What did you notice about yourself?

– I realized that I felt super good inside, after being friendly and kind, and I knew that I must have made her day better. I am going to try to always talk to new people or shy people, because they will be very happy when you talk to them, and it makes me feel really good, knowing I helped someone make a new friend.

How did performing a RAC contribute to your personal awareness and responsibility?

– This RAC helped me be aware that there are lots of shy people around in public places or at social events, and that they want someone to come over and talk to them, but they are just a bit scared to start a conversation. I now feel like I am more aware of the responsibility that I should have, and that I should always be looking out for those people who are alone.

Did you enjoy this RAC? Would you do it again? Would you change it, if so, how?

– I really enjoyed this RAC, and would definitly do it again, and I am going to make a personal goal, to try to always be looking out for those people who need someone to talk to if they are alone at a social event, or in any public place. The next time I see someone who looks shy and lonely, I will go and talk to them, and start a good conversation, and just try to make their day better, by making a new friend.

How did it contribute to your leadership skills?

– This RAC contributed to my leadership skills, by encouraging me to be a leader, and stepping out of the way to talk to someone who is shy or lonely. This has helped me be a supportive leader, by trying to include everyone.



DNA Model

DNA structure assignment:

In this activity we made a DNA structure out of coloured marshmallows and liquorice . Each colour of marshmallow represented either Thymine, Cytosine, Guanine, and Adenine.

DNA is structured in pairs of bases, so Adenine pairs with Thymine, and Cytosine always pairs with Guanine. DNA is shaped in a double-helix, and there is DNA in every cell exept for red blood cells. DNA can make two trends from the existing one strand, by unzipping itself, and because each base only pairs with the opposite base it wil create an identical copy of the DNA. DNA contolls information for how an organism can survive and reproduce. This project was very interesting and definitly helped me further understand how DNA is structured.

English 10 Synthesis Essay – “What effects does racism have on a person?”

I was very happy with my mark on my synthesis essay, and two things that I did very well was integrating quotes properly, and writing a good conclusion that makes the reader continue thinking after finishing reading my essay.

On future essays, I would like to improve on my intro sentence, and make sure to integrate my essay topic sentence in a way that intrigues the reader when starting to read my essay.




What Literature Has Taught Me About The Effects Of Racism

Racism has been around forever, and has effected individuals, and humanity as a whole. In “The Watch”, Elie was snatched from his home and his family and friends were killed in the concentration camps during World War II. During that time humanity lost more than 11 million Jewish people, and many more homosexuals and disabled people. All these people were killed or tortured, because of their differences. In Indian Horse, it describes the abuse, trauma, and racist mistreatment that the aboriginal kids went through. Saul and many of the other Aboriginal kids were raped and beaten. Many of the kids killed themselves because they wanted to escape their reality. Children were taken away from their families so the “Indian” in them could be erased. In “What Do You Remember Of The Evacuation”, the young Japanese girl and her family were forced to leave their home and all their belongings, and go to an internment camp. This girl ended up feeling ashamed of her skin which is horrible because it’s something she can’t change. She and her family were treated like animals because they weren’t white. Forever, people have treated others with racial discrimination, because humans aren’t able to look past their differences. Humanity has lost millions of people, due to genocides, or people ending their own lives because they weren’t treated properly. It makes me sad to think that after many killings and genocides because of racism, humans still aren’t able to look past the colour of each other’s skin, or the differences between people. Everyone should try to treat others with respect, and “treat others the way you want to be treated.” No one wants to be treated differently, so everyone should work hard to create a world where everyone tries to treat everyone equally.
