Flag Pole Lab Math 2018

In this lab, we had to find out the height of the Canadian flagpole in front of our school. We were supposed to use triangulation to calculate the height. Our idea was to measure from two different distances then see if they were the same. We measured from 2m and 10m. Our answer’s varied by about 2 meters. We developed another strategy to measure my height and my shadow’s height. We then took the quotient of my height/my shadow’s height. Then we multiplied that number by the hight of the flagpole. Which gave us an answer of 10.6. Which was not close to either of our other calculations so we went with that anyway.

Thoughts on Data Analysis 2018

1) I believe that statistics are very important in our society because it is the base of many facts, and of course facts are important because it (should be) is the truth. So statistics are a big part of how we find out about our world.

2) I learned that about 24% of statistics are mathematically flawed because when numbers are involved, the question of authority of that stat is usually not questioned. (Writing this after 3) I also learned that my made up statistic about statistics being made up on the spot was actually correct. Or so I have now read.

3) The problems with statistics is that they can be made up when told, did you know that 86% of statistics are made up on the spot? OK you probably got that that was made up but I think you understand my point. As well as when the study is being done, it is not done properly and there is a biased answer. Like if we asked only Winnipeg fans who they wanted to win the cup and our final outcome was that everybody wants Winnipeg to win.

COL Interview

I continue to believe that this job would suit me, there are ups and downs to this employment but the ups would be greater than the downs.

I love that I am able to walk with people through the big events of their lives. I get to be a part of marriages, child dedications, but also hospital visits and funerals.

Q: What obstacles have you faced to get where you are today?
I have my education in biblical studies and have spent many years volunteering locally and in other countries.

Q: What advice would you pass on to someone interested in what you are doing?

Make sure you have your family as first priority! Doing pastoral work can be very stressful physically, spiritually, and emotionally. If you are not careful to carefully structure your time, it can steal from family

health.

Q: What is the worst part of your job?
Doing funerals for tragic deaths; (i.e. child with cancer, accident, fentanyl, etc)
​​

Q: Do you think I would do well at this job? Be honest.
Not at 14, but I definitely see the potential for ministry in the future. You have the ability to sympathize and show genuine care for others.

What Pain Reliever Dissolves the Quickest?

Partners: Olivia Gale, RuoMin Zhang, Megan Kydd

Purpose

Our challenge today is to make the most realistic setting in our classroom to replicate a human’s stomach acid. So we searched online about ways that we could do it. Common ways to replicate stomach acid that we found online was just vinegar. I had a whole idea to mix vinegar with lemon juice because it would look cooler and more realistic, along with having a sound hose to replicate the esophagus as it went down but my group shut me down because we had 1 day to prepare and that took too much work. We also made sure to find the correct temperature of the stomach so we could use our heating pad to replicate it. We ended up doing the most common way of using vinegar and a heating pad.

• Beaker
• 5 test tubes
• Dropper
• Vinegar

Pills

• Aspirin
• Acetaminophen
• Tylenol
• Motrin

Procedure

• Separated vinegar into 5 test tubes
• Put Water into a beaker
• Turn on the hot plate until it is 37 degrees
• Heat up test tubes along with vinegar
• Remove test tubes and insert pills
• Wait to see which one dissolves first
• Clean up

Observations and Results

 First Aspirin Second Acetaminophen Third Tylenol Fourth Motril Fifth Advil

Conclusions

From our experiment we found that vinegar was useful in dissolving the pills (Except Advil). It seemed that the internet was correct in it’s idea of replicating stomach acid. We do not not know how Advil is supposed to work so we will have to do some follow up research on that because it did not dissolve at all. You can see in our chart the order of which pills dissolved quickest. With Aspirin and Acetaminophen being the quickest by a large margin over Tylenol and Motril.

Vocabulary of polynomials

Coefficient: Number before a variable

Base: The variable after a coefficient

Variable: An unknown number shown by a letter

Term: A number or variable/the sum of a number and variable

Like terms: Two or more terms with the same base

Polynomials: An expression made up of terms that are added or subtracted

Monomial: 1 term | 6x2

Binomial:   2 terms | 3a2 – 5

Trinomial:  3 terms | –w2 – 5w + 1

Polynomial: 4+ terms | 2s2t2 + st + 7t – 4

____________________________________________________________

Only like terms can be added

(1x + 2x2 – 3x)+(1x + 3x2 + 2x)

1x, 3x, 1x and 2x are like terms

1x + 3x +1x + 2x = 7x

2x2  and 3x2 are like terms

2x2 + 3x2  = 5x2

= 7x + 5x2

____________________________________________________________

Subtraction

Only like terms can be subtracted

(4x – 3x2)-(1x2 + 2x)

= 4x – 2x = 2x

= 3x2 – 1x2  = 2x2

= 2x – 2x2

____________________________________________________________

Multiplication

Using the distributive property, we multiply the monomial with each term in the polinomial.

(3x)(3x x 2x x 5x)

Multiply each term by the monomial

(9x2 + 6x2 + 15x)

____________________________________________________________

Division

Distributive property still applies

$\frac{6x + 4x}{2x}$

6x ÷ 2x = 3

4x ÷ 2x = 2

3+2
