words to live by

These words to live by are important to me because I believe that even if something is terrible you can still turn it into a good memory. I chose these pictures of Canada day because everyone was worried Canada wouldn’t be fun because it was supposed to rain, I kept telling everyone that even if it did rain we would still have lots of fun and we did, even though we came home from Castle park soaking wet.

Exploring Quadratic Functions

1. What is a Quadratic Function?
A quadratic function is in the form f(x) = ax2 + bx + c. A, b, and c are numbers that are not equal to zero. The graph of a quadratic function is a curve called a parabola. Parabolas can be open upward or downward and vary in “width” or “steepness”, but they all have the same basic “U” shape.

2.  a)This is a Quadratic Function:

     b)This is not a Quadratic Function:

3. No matter what the two sides of the parabola are always symmetrical.

5. a) when a < 0 the parabola becomes negative
i) maximum point

b) when a > 0 the parabola becomes positive
ii) minimum point

     c) when -1 < a > 1 the parabola becomes a straight line

     d) when a > 1 or a < -1 the parabola becomes narrow

6.  The relation ship between a negative and postive in a vertex 

7. When a and b are constant and you change the value of c, the parabola moves up or
down the y axis.

 

Root = 0
Equation: y = 1×2 + x + -1

Roots = 1, -1
Equation: y = 1×2 + x -1

Roots = above the x axis
Equation: y = 1x 2 + x + 0.5

Animalia
These animals are both from the Animalia kingdom because they are both mobile and both rely on other living things to survive.

Orcinus orca

Ursus arctos

Thaumarchaeota
These are archaeans because they don’t have a cell nucleus or any other membrane bound organelles.

Nanoarchaeum equitans

Euryarchaeota

Eubacteria
These organisms are eubacteria because they complex and have a lack of a cell nucleus and other cell parts.

Streptococcus

Lactobacillus

Protista
These organisms are protist because they don’t form a natural group, but they are often grouped together for convenience.

Euglena

Volvox

Plantea
These organisms are plants because they both go throw the photo synthesis process, and they both have cell walls.

Abies

Tulipa

Fungi
These are both fungus because the reproduce asexually.

Mushrooms

Moulds

Poem Analysis

This poam is about life and the many faults as well as treasures it has. The speaker is the poet Singh Narula and she I think she’s talking to human race in general.  The tone in this poem is serious and a little bitter sweet, it has a even mix of sad and amazing things we expirence in life. This poem is one stanza with 15 lines and does not rhyme. This poem containes imagery, and repitition. I think this poam does an amazing job of describing life in general for most people.

 

Photos

1. I chose photo one because I thought it showed all the challenges we face on a large scale.

2. I picked the second photo because it’s just a simple present. To me this symbolizes that sometimes the gifts in life aren’t extravagant but we should still be grateful for them.

3. I really liked the photo of the girl crying for line three because all though you can see a tear on her face, to me her eyes look like she’s wanting to over come the sorrow she has felt.

4. I chose the fourth picture because you can see the fear the woman is feeling in the photo. This is the type of fear most would feel while facing tragedy.

5. For number five I chose a photo of a magnifying glass because I think it represents discovery much like the fifth line of this poem.

6. Number six is a photo of an arm reaching, i used this picture to literally show someone trying to take an opportunity.

7. Number seven I used a sketchy like picture of two people making a pinky  promise, everyone has made a pinky promise at least once in their life and j wanted picture 7 to be something anyone could relate to about keeping a promise. Even if it’s just a silly pinky promise.

8. For eight I chose a picture of a man beating a punching bag. I think this raw photo does a great job of representing the “fight” humans face everyday.

9. Number nine was a photo of a check list, I thought the check list showed the goals we set over our life times.

10. For ten I chose a picture of two people hugging because what gesture feels more loving than a hug?

11. Number eleven is a man on top of a mountain. When ever I think of being adventurous I always think of mountains for some reason, so this is why I chose this photo.

12.  This photo was chosen because the ballerina is putting her all into the time she has on the stage and I think that’s how we should live our lives much like this line says.

13. number thirteen is a picture of the human brain because we are the smartest animals on this planet and that’s why the human brain does such a great job of symbolizing how we as humans can out smart anything.

14. number twelve is another picture of mountains because I just think mountains are so beautiful and one of the many beauty’s of life.

15. Finally for number thirteen I chose a picture of Justin Bieber smiling because he started off with nothing just a poor child with a single parent and he has completely turned his life around along with many others.mhis music has been a huge part of why I’m so postive about life and that’s why for me he is a perfect example of making life great.

Chemical Periodicity

Chemical Periodicity

Atomic radius versus atomic number
A number of physical and chemical properties are related to the sizes of the atoms, but atomic size is somewhat difficult to define. There is no precise outer boundary of an atom. The radius is one half the distance between the centers of two adjacent atoms. The radius of an atom depends on the environment in which it is found. For bonded atoms, we customarily speak of a covalent radius, ionic radius, and, in the case of metals, a metallic radius. For atoms that are not bonded together, the radius is known as the van der Waals radius. For comparison, all radii in the above table are covalent.

1. Which is the largest of the first 54 elements? The largest of the first 54 elements is Rubidium (37) with an atomic radius of 0.216 nm

2. Describe how the atomic radius varies within a period and within a family. As you move left to right across a period the atomic radius tends to decrease, however, the atomic radius will increase moving top to bottom through a family

3. Use your graph to predict the atomic radius of the following elements:
(a) cesium: 0.280 nm (actual 0.267) (b) tungsten: 0.150 nm (actual 0.142) (c) thallium: 0.165 nm (actual 171) (d) radon: 0.135 nm (actual 0.141)

4. Which group of the main group elements contains the largest elements? The group of elements containing the largest elements are the Alkali metals located on the far left side of the periodic table.

 

Ionization energy versus atomic number                                       1. How would you explain ionization energy to your partner? The ionization energy is the amount of energy required to remove the most loosely bound electron, from the valence shell of its atom. Depending on the size of the atomic radius, there will be a stronger or weaker ionization energy binding that atom together.

2.  How does the ionization energy vary within a period and within a family? Within a period moving from left to right the ionization energy increases due to smaller atomic radii, in a family moving from top to bottom, the ionization energy decreases due to larger atomic radii

3. Which element on your graph has the strongest hold of its valence electrons? Helium has the strongest hold of its valence electrons, not only is it a noble gas (on the far right of the periodic table) but it is also located in the top row of its family, this demonstrates that it has a very high ionization energy
(a) Write the electron configuration for chlorine. Chlorine: 1s²2s22p63s23p5
(b) Which electron is lost when 1251 kJ/mol of energy are applied to a sample of chlorine atoms? Because of chlorine’s natural stable state the chlorine atom would not likely gain nor lose an electron, however, a chlorine ion has a charge of -1 indicating that its outer P orbital (usually P5) would gain one electron to complete its valence shell thus changing it to P6

4. Compare the ionization energies of metals to nonmetals. Metals generally tend to have a higher ionization energy as they are located towards the right and top of the periodic table. Nonmetals typically carry a lower ionization energy and are found towards the bottom left of the table.

Melting point versus atomic number
1. Describe the trend of melting points within a period
Melting points vary for each period, they have patterns that depend on each of their positions in the periodic table. The melting points of group 1 elements decrease going down the group. This is caused by a decrease in the forces of attractions within the atoms.

2. Which group of elements tends to have the highest melting points
The group of elements that tend to have the highest melting point is group 14 because the elements with lower periods have similar melting points.

3. Tungsten is used in incandescent light bulbs because it has an extremely high melting point. Which element on your chart could be a reasonable replacement for tungsten? Why?

4. Tungsten has a high melting point and another element that could replace tungsten is platinum, it has a high melting point and can withstand heat.

 

Density versus atomic number
1. Describe how density varies within a period.
The first few periods with lower atomic numbers have a smaller mass than the periods with a higher atomic number.

2. Compare the densities of the elements in the second period with the elements in the third period.
The densities in the the second period are significantly smaller than the densities of the second period.

3. Assume that the transition metals given in the table are representative of the other members of this group. How do the densities of the transition metals compare with those of the elements in the main group?
The transition metals are very spread apart from each other compared to the rest of the group.

4. Explain why aluminum and magnesium are more suitable than iron for use in some airplane parts.
They are more suitable because they are lighter than iron would be on the plane.

 

Electronegativity versus atomic number
1. Describe how electronegativity varies within a period.

as you move across a period the electronegativity increases

Describe how electronegativity varies within a family.

as you move down a family the electronegativity decreases

Capital Punnishment

Capital Punishmentt
Two Fishermen -by

This is a photo taken before the hanging of Kreis Kaplitz. He was hung on January 2nd in 1946 for killing 5 American airmen in Landsberg Germany.

 

Capital punishment also known as death penalty, is the legally authorized killing of someone as punishment for a crime. In pre confederation Canada, many criminal offences were punishable by death until the last two men where hung in 1962.

If the story Two Fisher Men took place in Canada, it probably would have been in the 1920’s. I think this because of how the hanging was described, in the 1950’s death penalty’s would happen in jails in front of small groups involved in the case. In the story two fishermen the hanging is shown to the whole town, and I understand why they eventually made hangings privet events after reading this story because of the way the public could react. Another reason why I think this happened I the 1920’s is because it didn’t seem like their was much of an investigation into the details of this case. We have no idea if Thomas’ wife actually got raped or if that is just his side of the story.

Personally I do not think Thomas Delaney should have been hung because as far as we know he was just defending his wife. I personally don’t support capital punishment so I wouldn’t support the idea of killing someone for any reason but we don’t even know if he killed intentionally, or if it was an accident, and I don’t understand how anyone could execute a person when they don’t have all the facts first. Even if it wasn’t an accident Thomas Delaney was trying to save his wife from a rapist! Jail is one thing but hanging someone who was protecting their family is another
