Here is the prezi for this project.

Compound Project - Zinc Oxide

Zinc Oxide

The chemical name and formula of Zinc Oxide are the same. The name is ZnO. Although it is most commonly called "Zinc" and "Zinc Oxide" another name that can be used is "Zinc White" as Zinc Oxide is white. The physical and chemical properties of Zinc Oxide are that it is odorless, white, a powder feel and it is nearly insoluble in water but it can be soluble in some acids It is also can form colourless crystals. Below is what this compound looks like which as you can see is a white powder.



Zinc Oxide is often added into different foods and regular everyday items. Some items are different sunscreens and creams. click here for some different sunscreens with zinc oxide in them. Although some common ones are batteries, some metals, foods and more. They are also starting to use zinc in third world countries as some child deaths are caused by zinc deficiency which can easily be fixed with sending batteries and other zinc rich objects to those countries. Zinc is also used to galvanize metals (coat metals with zinc) like iron and steel.
Zinc is also found is many cosmetic and over the counter drugs and creams like makeup, nail products, baby lotions, bath soaps, and in some skin protectors like diaper rash creams and sunscreens.
Zinc Of The Periodic Table:

Name: Zinc, Zn

Atomic Number: 30

Mass Number: 65.4

Ion Charge: 2+

Zinc Oxide is made up of Zinc and Oxygen (which is why is called Zinc 'Oxide')

Bohr Model For Oxygen: 

Oxygen is #8 on the periodic table which means it has 8 Protons and 8 Neutrons. It is also a 'Non Metal" On the periodic table. There isn't a way to have a picture of Oxygen as is it transparent and cannot be seen but it is still all around us at all times.

Symbol: O

Atomic Number: 8

Formula: O2

Mass: 16.0

Ion Charge: 2-

Cons Of Zinc Oxide:

3-3A Lab: Calcium In Water

What Did You Find Out?
1. What changes (state, colour, shape of solid, formation of gas) did you observe during the chemical reaction?
A: With the phenolphthalein in the water, when the calcium is placed in the water it turns pink. The water bubbles and the calcium begins to jump around.
2. What is the likely identity of the gas that was produced?
A: Likely, the gas that was produced was hydrogen.

2-1B Lab: Generating and Burning Hydrogen Gas

2-1B Lab: Generating and Burning Hydrogen Gas:

Analyze:
1. The zinc starts to bubble and the bubbles surrounds the zinc. It does not change the colour of the zinc but, it does change the colour of the water. Eventually the water will become white.
2. Eventually the zinc might start to change colour if left in for a very long time, but another thing that could happen is that it starts to disintegrate.
Conclude And Apply:
1. The appearance of the zinc is still its original colour (silver/grey) and there are many bubbles surrounding it and continuously moving.
2. The gas was put into a test tube.The tube was then turned over and a a glowing wood splint was put to the spout of the test tube resulting in an explosion sounding like a high pitched "pop".

Take Your Kid To Work Day - Swiss Chalet - Director Of Operations

My dad is the director of operations for 5 Swiss Chalets. The 5 locations are Langley, Newton, Surrey, Maple Ridge and the brand new one opening on Monday, November 12 2012. At the start of the day we went to the Surrey Swiss Chalet before it even opened. My dads job is not really a job I am able to shadow or help with as its all business and changes depending on the day. At the second location we went to, which was Newton my dad got me to throw on an apron and help one of the kitchen staff, Baljeet roll up spring rolls for lunch time. We finished that and my next job was to put pepper in the pepper shakers. At the third location we went to in Langley, I learned how to do the dishes done by Tammy and ribs done by Josh. Then Tammy somehow talked me into getting into the Swiss Chalet Chicken suit. It was quit the job trying to get into that thing. It actually took us 40 minutes to figure it out and get me into it. I then with limited vision walked to the front of the store going to the sidewalk and waving to people and pointing to the Swiss Chalet sign.  We then dropped a couple things off at the Maple Ridge store and headed to the new Poco store for the staff training. The training went from 4-9 and will happen 3 days more including dry runs and family and friends night to practice for opening day. It was neat seeing the behind the scenes of what each job has to do. I had never realized how much people had to remember to do in the restaurant business. Although I didnt actually do much of my Dad's job I still learned about what he did and about the other jobs that make Swiss Chalet work. It also made me realize that the restaurant business is not for me.

Van Der Graaf Generator Blog - Jordyn

Van Der Graaf Generator

The Van Der Graaf Generator is a machine that has a big aluminum ball on top of it and has a tube below it, that contains a rubber belt that when the machine is turned on it spins around. This movement causes the electrons to move around. With hands on the ball, the electrons then go into the persons hand. That then causes tingling. If you take one hand off of it and touch something metal or another persons hand you will feel a shock.

What I Saw:

One of the first things we did was Mr. Brown got his dead cat (the fur of course) and placed it on the generator. The electricity went through it and as that happened the ends of the fur rose along with the hair.

When a humans hand were put on the generator that persons hair was soon rising up.

That is what the Van Der Graaf Generator looks like. As the person touching the generator or holding hands with someone touching it, touches a sink or something metal, the persons hair for that moment goes down and back up when the person stops touching the metal object.

What Experiments:

We did a few different experiments that I briefly  descried earlier. One was using rice krispys into a plastic bag, then when put on the generator they tried to get away from from each other making them go all around in the bag. Another one was the Cat Fur one which I explained earlier, then we had a student put their hands on it making their hair go up. After that we did the same thing with a student but then we added them holding hands which made the electricity go through all three people. Then Mr. Brown told the person to touch the sink causing a shock to go through all three of the people. After that we started with one person touching the generator with one person then touching the other persons hand also creating a shock. For all of the experiments the people were all standing on Styrofoam.  

What They Proved:

These experiments proved how amazing electricity really is. It proved the fact that static electricity is very interesting in how things react to it. Like the hair going up. It also proved how even hair on a human is affected when the persons hand is put onto the generator. 

Comparing Differentiation in Embryos

Comparing Differentiation in Embryos:
What To Do:
1. The embryo that has the development of a chicken, fish, human, rabbit, salamander, and tortoise. Is the human embryo or III, as you can see all of those animals in the development stages.
2. Three similarities: They all three go through stages of growing and changes. They all look alike at one point in the development. A third similarity is that they don't ever start off the same as they end.
What Did You Find Out?
1. No. At the start of development what is shown is completely different than what it ends up as. Like III ends up looking as a human baby. In II it is much smaller and skinnier as it has not grown.
2. Depending on which one, as I starts changing at the third stage, II starts to change at the second stage along with III.
3. In the first stages none of the organs or parts of the animal are developed so it ends up looking totally different than the end result. Human babies at first look like a fish until about the last stage when you see it is actually a human baby, although I is not as different than the first stage to the last.

Terry Fox - Blog - Jordyn Reeves

Terry Fox

History:

Terry Fox was born on July 28, 1958, in Winnipeg Manitoba. In 1966 him and his family moved to Surrey, British Columbia. Soon after in 1968 the settled down in Port Coquitlam also in British Columbia. Terry was a very active teenager and played many sports such as soccer, rugby and baseball. Terry had a love for basketball but was always too short and at that time was not the best player. At the time he was just living a normal life and enjoying playing sports. 

In November, 1976 Terry was distracted and crashed into the back of a pickup truck. Although his car was ruined, he only came out with a sore right knee. The pain came back in December but he ignored it and continued playing basketball and doing everything as normal. By March 1977 the pain had become more severe and he finally went to the hospital. There, he was diagnosed with osteosarcoma a form of cancer that often starts at the knee. Terry believed it was the car accident had weakened his knee but the doctor stated that that was not a factor in the cancer forming. He was told that his leg would have to amputated and that chemotherapy would be needed.  As at that time medical treatments were new. He only had a 50% chance of survival. After the amputation Terry was walking 3 weeks after. Fox ended his treatment with new purpose: he felt he owed his survival to medical advances and wished to live his life in a way that would help others find courage. The night before his cancer surgery, Fox had been given an article about Dick Traum, the first amputee to complete the New York City Marathon. The article inspired him; he embarked on a 14  month training program, telling his family he planned to compete in a marathon himself. His plan was to run across Canada.  This run across Canada was named the marathon of hope.  The route started in St. Johns Newfoundland and was supposed to end in Thunder Bay Ontario. Throughout his run, he was trying to collect money for cancer research. The run was doing well until he was experiencing flu and cold like symptoms. He kept going not really complaining about it.On September 1, outside of Thunder Bay, he was forced to stop briefly after he suffered an intense coughing fit and experienced pains in his chest.  He kept going until a few miles later he experienced the same issues he had a few miles before, he then asked Doug to drive him to hospital where he was told the cancer had came back and spread to his lungs. Then he was forced to end his run after 143 days and 5,373 kilometers (3,339 miles). In the months following, he received multiple chemo treatments although the cancer was still spreading. He sadly died at 4:35am in Royal Columbian hospital, on June 28, 1981.

After Terry's death his legacy continues. Schools and programs across the globe continue to raise money for his cause. Every year there is a school Terry Fox run. This year one of our fundraisers were selling balloons for one dollar, as well as donations boxes  in your RAP class. Two men spoke at the assembly that both had experienced a type of cancer and have survived. After the assembly the competitive runner were let out followed by the rest of the school. It was really cool seeing all of the students walking/running. I find the Terry Fox run to be a great thing that schools do. I remember when I first did it and learned about him how fascinated I was at a young age. I hope that schools never stop the Terry Fox run. As we need to keep Terry's legacy going. 

6.1 Meiosis Questions:

1. What is the purpose of Meiosis?
Answer: The purpose of Meiosis is to create new cells with half the amount of chromosomes. Without meiosis the sperm cell and the egg cells joining during fertilization it would produce to time the amount of chromosomes instead of one half of the original number of chromosomes.

2. How do cells at the end of Meiosis differ from the cells at the end of Mitosis?
Answer: In Meiosis after the DNA replicates it goes into to daughter cells. After that those two daughter cells split into two groups of two daughter cells, meaning there is now four daughter cells. At the end of
Mitosis it is different than Meiosis. At the end of Mitosis, there are two daughter cells unlike Meiosis.       









3. What is a Gamete?
Answer: A gamete is what carries haploid chromosomes. These gametes are specialized for reproduction. In animals gametes in males are called sperm cells. In females the gamete cells are called egg cells. The gametes are necessary for reproduction.

4. How are diploid cells and haploid cells different? What human cells are examples of each?
Answer: Diploid cells are different from haploid cells. Diploid is having two sets of homologous chromosomes. Haploid is having one set of daughter cells. (4 daughter cells). A human example of Haploid cell is the sprem and egg cells. A human diploid cell carries two sets of chromosomes.

5. How many phases are there in Meiosis? Why is each phase important?
Answer: There are 5 phases in Meiosis. These phases are, Prophase, Metaphase, Anaphase, Telophase and Cytokenisis. Each phase is important as if one stage was missing cells would not be able to reproduce which means no new cells would be made. Each phase changes a part of the cell. Say if there was no Cytokenisis the cells would not be able to separate into more daughter cells.

6. Why do two brother look different from each other if they came from the same parents?
Answer: A person has a set of chromosomes. One from their mum and one from their dad that join together to make that child. The two halves are joined together and the middle of each chromosome has genes and every DNA has two copies of each gene one of those genes is more dominant that the other. The dominant gene is what makes everyone different. The gender of the child is random. You could say nature chooses one half and that is the gender. of traits are taken from the mother and father. Also  This means that every sperm cell contains a random mix of the father's parents' genes. The same thing happens when forming eggs. Therefore, each child that a couple produces is a random mix of the four grandparents' genes. 

Mutated Animal Project: Josie And Jordyn

Animal: Kangaroo Rat. Climate: Desert

1. Bigger arms resulting in it being easier to dig holes in the ground to get away from the many predators it has. It will also make then be able to jump a little higher with being able to use their arms to take off and jump higher than they already can also making it easier to get away from larger predators and large slow predators.

2. Negative mutation would be to decrease the ears. Decreasing the ears makes it harder to hear predators approaching. The Kangaroo rat would be soon extinct if it had small ears and bad hearing.

3.  The colour of the rat would be changed. It will not affect the survival. The Rat might be black, or white, a darker brown or grey. Other than the appearance it will not be affected in any way.

1. This is a kangaroo rat with no ears.

2. This is if the kangaroo rat had long arms.

3. This is an example of a Neutral Mutation. This Kangaroo rat is Grey/White and not the normal light brown colour.

Is It Right To Change Someone's or Somethings DNA?

Is It Right To Change Someone's or Somethings DNA?

Depending on who your are and how you think, you might have a different perspective  than other people. In my opinion I think for a human, unless you need to change it to save their lives I don't think you should. Because if they do not need it it might change the quality of the persons life or how they may act or feel about certain things. Another thing that may happen if the DNA is changed is tha the protiens could be made incorrectly causing the proper proteins to not get to the proper place resulting in sickness or death. For animals, depending on the reason it might be ok. If it is a test, using one animal might be ok. Although if it may be fatal I think it is not worth it. Changing the DNA might be needed in some circumstances but if they is not a valid reason I think it shouldn't be done for the safety and well being of the person, thing or animal. DNA could be changed and become not in the right shape which could affect the person, animal or thing. Overall I do not support this idea.
