Bruce's Make a Difference Final Reflection

Hi,
Mr Harbeck told us each to create a post that was about our Make a Difference movie. Here is my reflection.

Changes
Some changes we made to our video were, choosing to remove voices and just adding in text. Another thing we did was add in a better background for the begging of the video and adding in more convincing pictures. Some of the comments we got were really helpful for example, a comment that told us to remove voices and substitute it with text.
Expert
Our expert was Ellen Gahigi, a Field Coordinator for the United Nations.
Three important points the expert gave us were...1) How poverty in Somalia is caused, 2)What the UN is doing about this problem, 3)What we can do to help support Somalia. What we learned from our expert is that anyone can help Somalia or any other country in need by doing one thing at a time.
Success
In my opinion our greatest success was being able to find an expert and explain what we can do to help heal the problem in Somalia. Skills that we will take from this experience is being able to explain what is happening in parts of North East Africa. What frustrated us during the movie project was not being sure on how to approach our subject. Strategies we used to be successful were, assigning different parts of the project to each member, research and just having good teamwork.
Importance
This project is important to the grade 8 students because it teaches us that the world does not revolve around us and that each and every person should care for each other.
How I will Make a Difference
I will make a difference in the future by taking what I have learned this year and passing it on to other people.

Bruce's Fraction Growing Post

I couldn't upload my video, so here is the link for now.

http://www.ustream.tv/recorded/5683250

The next thing we had to do is show how to multiply a fraction by a fraction, a fraction by a mixed number and a mixed number by a mixed number.

Fraction x Fraction

1/2 x 1/2

1)you multiply the numarator by numarator to get the first answer.

1x1=1

2)you multiply the denominator by denominator to get the second answer.

2x2=4

so the answer is 2/4 (always simplfy)2/4=1/2.

Fraction x Mixed Number

3 x 1/2=

1)the whole number (3 ) is the number of groups.

2)the fraction (1/2) is how many in each group.

3 x 1/2=3/2(simplfy)1 1/2

Mixed Fraction x Mixed Fraction

When converting you use the denominator to decide the number of parts in 1 whole.

2 1/2 x 1 3/4=?

2/2 + 2/2 + 1/2=5/2

4/4 + 3/4=7/4

7/4 x 5/2= 35/8(simplfy) 35 divided by 8 = 4.375

4 x 8 = 32

35-32=3

so the answer is 4 3/8

Bruce's 3 Q's on Percents

Hello,
Today Mr Harbeck told us to pick any percent questions and answer them, so here we go.

Pg 148

2)How can you calculate a cost of an item with tax just in one step.
In my opinion I would multiply the original number by a single percent greater than 100.
e.g. 111% of 100=1.11 x 100
=111
Pg 146

2) gst is 5%, pst is 7% and you purchase an item for $100.

a) How would you represent the 5% and 7% on a 100 grid.
Since it's out of 100 I would just color 5 squares representing 5% and 7 squares representing 7%.

b)How much is the gst and the pst.
Since it's out of 100 the gst would be .07 cents and the pst would be .05cents. The reason I thought this is because 7% and 5% wouldn't be $7 and $5 worth of tax so that's why I turned it into cents.

c)How much tax does a person pay all together.
A person would have to pay 12% worth of tax all together.

5)
a)Describe 2 ways you could calculate the total tax of an item.
First way is by using a ratio table. The second way is by using the formula where you multiply the original number by a single percent greater than 100.

b)Which method do you prefer to use? Explain.
I prefer the ratio table method because, it's the method I'm most used to.

I chose to do this question because my computer wasn't showing all the questions I had chosen.

Bruce's Scribepost, Pythagoras

Hello,
Today Mr Harbeck assigned a few of us to make a scribe on one of the seven question. My question was #6.


6. Determine the length of the leg for each right triangle.
A)
One leg=7cm
Second leg=?cm
Hypotenuse=25cm

c(sqrd) - a(sqrd) = b(sqrd)
25cm(sqrd) - 7cm(sqrd) = ?cm(sqrd)
625cm(sqrd) - 49cm(sqrd) = 576cm(sqrd)

square root of 576=24cm
b=24cm
B)
One leg=24cm
Second leg=?cm
Hypotenuse=26cm

t(sqrd) - s(sqrd) = r(sqrd)
26cm(sqrd) - 24cm(sqrd) = ?cm(sqrd)
676cm(sqrd) - 576cm(sqrd) = 100cm(sqrd)

square root of 100=10
r=10cm

If you think it's wrong please leave a comment, because I just did my scribe half asleep.

Bruce's Scribepost, question 6, Dec 14.09

Hey guys,

Today Ms.U picked some of us to do a scribe on one of the questions. My question to answer was question number 6.

First leg=25cm squared
Long leg=144cm squared
Hypotenuse=169cm squared

a.Write an addition statement using the
areas of these three squares.
25cm (squared) + 144cm (squared) = 169 cm (squared)


b. What is the side length of each square?
The side length of each square is...
25cm (squared) = 5cm
144cm (squared) = 12cm
169cm (squared) = 13cm

c. Describe, using words and symbols, the
relationship between the side lengths of each square.
a (squared) + b (squared) = c (squared)
short leg + long leg = hypotenuse

That's my scribe PLEASE COMMENT

Bruce's Winnipeg Harvest

Hey guys,

Mr Harbeck chose people to go and check out things that happen at Winnipeg Harvest. The people he chose from our class were me, Jomari and Tamika. Mr Harbeck also told us to write about our experience at Winnipeg Harvest.

Before we started our tour we met a man called Richard. Richard told us about all the work Winnipeg Harvest does each and everyday. Richard also told us about all the thoughtful volunteers who choose to use their time helping people at Winnipeg Harvest. After all the talking we started our tour, we met a few volunteers(can't remember their names), they told us about what they do at Winnipeg Harvest. We eventually got an assignment on stacking potatoes, our goal was to beat our group's weight(can't remember weight). We stacked 1100 pounds of potatoes and 60 or so pounds of onions. We unloaded 3 big crates of potatoes and half a crate of onions which came to 1100 pounds of potatoes and 60 pounds of onions.

After all that stacking, we went into the main room and had some hot chocolate and some other snacks. Richard came in and told us what a wonderful job we had done. He also told us some jokes, one of those jokes were Whats the difference between boogers and broccoli(children eat boogers). He told us that all the potatoes we had stacked will help 110 families. He told us that his dream was seeing the Harvest close, because when it closes it means that there would be no more hungry people. Richard thanked us for our help and we were on our way back to school.

(Bruce), Jomari, Warren, Gordon Pay it Forward

Hey guys,

Mr Harbeck and Ms Lee asked us to create a project on the movie "Pay it Forward". They also told us to do some act of kindness and write about it on our blog.

Part 1

What is "Pay it Forward"?

"Pay it Forward" to me is, "Not thinking of yourself too much and thinking of the unfortunate people".

Part 2

What was your Pay It Forward act of kindness?
My Pay it Foward act of kindness was going out with some of my friends on a cold day and handing out cards to people, such as mail men and the people at Ashcroft. We also put cards in the people's mail box and their parked cars.

Why did you choose this activity?
We chose this act of kindness because we thought that some people didn't recieve any gifts or cards on Christmas. Thats why we chose to hand out cards.

Who did you help?
In our opinion we think that we helped lot's of people and that we made people know that Sargent Park School is a caring school.

What did you do?
We handed out cards to people

When did you do you act of kindness?

We did our act of kindness during the weekend and during the lunch hour on weekdays.

Part 3

How did your act of kindness go?

Our act of kindness went very well, everyone did their job and we handed out each and every card.

What Happened?

We went around the Sargent Park area and handed out cards to people, houses and parked cars.

How did you feel?

Even though we felt cold, our hearts kept us warm because it made us feel warm knowing that we were making someone feel like; someone cared about them.

How did the person or people react?

I think that the people think that Sargent Park students are caring and thoughtful kids.

Did you ask the person or people to "Pay It Forward"?

Im each card we included the words "Pay it Forward" in a sentence telling the person to go out and do something good for someone else.

How did they react to your request?

I think that people are gonna go out and donate or volunteer somewhere, and make others feel like someone cared about them.

If you did not ask the person to "Pay It Forward" how come?

We asked the person to Pay it forward in each and every card.

Part 4

Why is the idea of "Pay it Forward" important?
The idea of "Pay it Forward" is important because it makes "you think more of the unfortunate people who don't have what you have".


Has your act of kindness made a difference?

My act of kindness has made a differance because, it has made someone think that there are people who care about them and that their life isn't worthless.

For proof we did our project, just look at some of the pictures I posted.

How I Stoped an Alien,Bruce8-16(late)

It was an ordinary day all the sudden a UFO landed and threatened to take over the Earth. Unless I answer 3 of it's proportional questions correctly the alien will take over the world.

The first question was:
A small gear turns 18 times in the same time that a large gear turns 4 times, how many times will the large gear turn if the small gear turns 54 times?
In the same amount of time that the small gear turns 54 times, the large gear would have turned 12 times.The alien said it was right but not to be too happy because it was probably just luck the answer was right.

The second question is:
Look at the pattern, set up a proportion you could use to find the number of small squares in Figure 7.
In figure 7, there would be 14 squares. The alien is getting nervous which means I was correct and all I needed was one more question to go.

The third and last question:

The dosage of a certain medicine for a child is 2.5 ml for each 3 kg mass of the child. What is the dose, in millilitres, for a child with a mass of 16.5 kg?
For a child with a mass of 16.5 kg, they will have a dose of 13.75 ml of the medicine. I got all three questions right which meant I had defeated the alien. The alien left and I had saved the earth!

Sorry about not having any pictures, my computer wasn't working right.

Please comment

Bruce's Scribepost, Nov.19

Hey guys,

Well today we went over some of the homeworrk we were assigned to do.
For example...
Factors of...
1-1
2-1,2
3-1,3
4-1,2,4
5-1,5

We also went over some definitions, such as...
Square Numbers-the product of a whole number multiplied by it self
Example...9=3x3
Factors-a whole number which divides evenly into a whole number leaving no remainder.
Example...16=1,2,4,8,16
Prime Numbers-a whole number greater than 1, that has only 2 factors. The 2 factors are 1 and itself.(1 is not a prime number)
Example...
2,3,5,7,11,13
Prime Factors-factors that are prime numbers.
Example...
10=1,2,5,10(the prime factors are 2 and 5)

After homework check we went into Prime Factorization.
Here are a few examples.
18=2x3x3
24=2x2x2x3
36=2x3x2x3
144=3x4x3x4
144=2x2x2x3x2x3
I couldn't draw a factor tree so just look at Ronny's or someone who has a factor tree if you want to understand prime factorization easier.
Than the lady(can't remember her name) told us that the way to find out which one is a perfect square is that it is to have even pairs of the same numbers.
Example...
36=2x3x2x3
2 and 2 are 1 pair
3 and 3 are another pair

If you don't understand what I'm doing ask Mr Harbeck or the other teacher.

Homework is do pages 24 and 25 in your math book.
PLEASE COMMENT!!!

Scribepost, Proportion, bruce 8-16

Hey guys,
Today Harbeck told me to create a post on Proportion.

You can solve proportional reasoning using a fraction, a unit rate and a proportion.

Definition(s)

Proportion-is a relationship that says that two ratios or two rates are equal

As I said before a proportion can be expressed as a fraction, unit rate and a proportion.

Examples

Fraction
60 sit ups in 3 minutes

20 sit ups in 1 minute

You have to find what number makes the two proportions even.

60 sit ups/3 min

20 sit ups/1 min

you have to divide by 3 to get the 20 sit ups in 1 min

Unit Rate

3 plants/0.5m squared

6 plants/1m squared

First you have to find how to get from 3 to 6.

If you know how to do it the answer will be times 2

so do it on both sides and you get 3 plants multiply by 2 is 6 plants

than 0.5 m sqrd multiply by 2 is 1 m sqrd

Proportion

3 plants/0.5m sqrd

? plants/85m sqrd

First you find out what 85 divided bye 0.5 which is 170.

After that you multiply 170 by 3 and you get 510.

Which means the missing number is 510 (510 plants/85m sqrd).

If you don't understand what I mean go to this link

http://http//ebook.mytextbook.ca/view.phpp=a265bfa3f4dd60e47b8b106bbb8955e099f86c92&c=1

and look at the Key Ideas on page 66

Bruce's %%%%%'s Rate Growing Post

Part 1...

Define Rate & Ratio

Ratio-compares 2 quantities measured in the same units.


Rate-compares 2 quantities measured in different units.

Difference Between Rate & Ratio

Ratio compares 2 quantities measured in the same units. Rate compares 2 quantities measured in different units.

One Question From Page 60

Determine the unit rate in each situation:

a.) An okra swims 110 km in 2 h.

b.) A Canada goose flies 800 km in 12.5 h.

c.) Cathy plants 45 daffodils in 30 min.

One Question From Page 61

Which glacier melts faster if the Sask glacier melted 1.5km in 75 years and the Peto glacier metled 1320m in 70 years?

Sask

1.5 km (1500m)in 75yrs divide by 75

20m/year

Peto

1320 m in 70yrs (1923 - 1993 equal 70) divide by 70

19m/year

The Sask glacier melted more.

Part 2...

Spaghetti Sauce Ingredients

This recipe serves 8 people.

1/2 lb of ground beef

1 medium onion diced

1 celery finely diced

1 clove garlic

14 oz can of tomato chopped

1/2 can of tomato paste

1 tsp parsley

1 1/2 tsp basil

1 tsp oregano

1 tsp sugar

1/2 tsp worchestershire sauce

1/2 tsp seasoning salt

1 bay leaf

1)What would the recipe look like if it had to serve 10 people? Show your calculations.

3.75 lbs ground beef

2.5 medium onion diced

2.5 celery finely sliced

2.5 cloves of garlic

35 oz can of tomatoes chopped

3.75 can of tomato paste

2.5 tsp parsley

3.76 tsp basil

2.5 tsp oregano

2.5 tsp sugar

1.25 tsp Worchestershire Sauce

1.25 tsp Seasoning Salt

2.5 Bay Leaf

I multiplied the 4 servings by 4 and got 10, than i divided each one by 2.5 which gave me 4.

2)What would the recipe look like if you had to only serve 1 person? Show your calculations.

0.375 lbs ground beef

0.25 medium onion diced

0.25 celery finely sliced

0.25 cloves of garlic

3.5 oz can of tomatoes chopped

0.375 can of tomato paste

0.25 tsp parsley

0.376 tsp basil

0.25 tsp oregano

0.25 tsp sugar

0.125 tsp Worchestershire Sauce

0.125 tsp Seasoning Salt

0.25 Bay Leaf

I divided the original ingredients by 4 and got this answer.

My scribe looks long because my computer double spaces my writing on blogger for some reason.

Well this is my growing post, hope you liked it.

BOB On Ratios by. Bruce 8-16

Hey guys,



Today Mr.Harbeck told us to create ratios on the picture we use and comment on them in our comments section.

















Pt. 1
Harbeck told us to use...

1)Part to Part-2 term ratio
2)Part to Whole- 2 term ratio
3)Part to Part to Part- 3 term ratio
4)Part, Part, Part to whole-2 term ratio

To create ratios.

1) greens to blues
3 : 3
2) greens to whole
3 : 12
3) gold to greens to blues
1 : 3 : 3
4) greens, blues, orange to total
3 , 3 , 1 : 12

Pt. 2
Harbeck also told us to create questions about the ratios and answer them in the comment box.

1) What type of ratio terms are the numbers 1, 2, 3 and 4.

2) Give an example of an equivalent fraction.

3) Give an example of a simplified fraction.

Don't forget to study for the ratio test on Wednesday. Don't forget to study the numbers Harbeck gave us in the homework book.






___________________________________________________________________

Hey guys,

Harbeck told us to make a scribepost on the test.

1)What were the mistakes you made on your test?
Some of the mistakes I made on the test were Question #18.
The question was...
In a student election Carol gets 60% of the voted. If there were 485 votes cast, how many votes did carol get.
My answer was this.
289/485=(0.595)876288
0.595 x 100=59.5
59.(5)rounded up=60
carol got 289 votes
My mistake was forgetting to use a table ratio.
I will remeber that when you get a percentage question you should use a ratio table.

2)Write 2 questions that gave you difficulty on the test answer them in your comments section.

Question # 8
A picture frame has a width to length ratio of 5:7. If the width of the photo is 9cm, the length of the photo is

a)11 cm b)12.6 cm c)14 cm d)16 cm

Question # 7
A rapid transit train has 39 passengers on it as it starts it's run. At the first stop 12 passengers get off and 18 passengers get on. What is the ratio of the number of passengers who were on the train as it arrived in the first station to the number who were on the train when it left the first station? Express your answer in lowest terms.

a)2:3 b)13:15 c)18:12 d)27:39

Please leave a comment on the questions.

Bruce's Scribepost, questions 12-13, Oct.17-09

Hey guys,

Last class Mr.Harbeck told us to answer the question we were assigned to answer. My questions were questions 12 and 13.


Question #12.

In a class of 32 students, there are 24 girls.

a) What is the boys to total students ratio?
Express the ratio as a fraction and a
percent.

Ratio - 8:32 boys to total

Fraction - 2 over 8 (I simplified the answer by dividing both numbers by 4,
8/4 = 2 and 32/4 = 8)

Percent - 25% (8 is 25 percent of 32 and 32 is 100% of 32 so 8+8+8+8 = 32. One eight is 25% of 32. 8/32 = 0.25( 0.25 x 100) = 25%.

b) What is the girls to boys ratio? Use
ratio notation to express the ratio.

8 : 24 boys to girls

Question #13

A soccer team played 28 games and won
4 out of every 7 games. There were no
tied games.

a) How many games did they lose?

The team lost 12 games. ( 1. 7-4 = 3 2. 7 x 4 = 28 3. 3 x 4 = 12 games lost )

b) What was the team’s win–loss ratio?
Explain how you got your answer.

16 : 12 win to loss ( I calculated the losses and got 12 and got 16 as the wins so 16+12 = 28 games)

c) If this trend continues, how many losses
would you expect the team to have
once they have won 20 games?

Well I think 28 games plus 20 more win games the teams ratio would be

36 : 12 wins to loss

Thanks for reading my scribe please leave a comment.

Bruce's coin, math, oct-13-09

Hey guys,

First of all I'll talk about my estimate to how much money is in the jar.
Compared to my estimate the difference from my estimate to the exact amount was a difference of $58.00.

Estimate= $100 American
Answer= $158 American
Difference= $ 58 dollars
__________________________________________________________________

How Many Coins Are in the Jar?
(American Jar)

Money Rolls Value

Pennies 1 cent - l,l x 4 =8 -$1

Nickels 5 cents - l,l x 4 =8 -$4

Dimes 10 cents - l,l x 4 = 8 - $10

Quarters 25 cents - l x 4 = 4 -$10
28 rolls $25 =$100.00


Redone Table

Money - Rolls - Coins in Roll -Total
1 cents - 8 - 50 - 400

5 cents - 8 - 40 - 320

10 cents - 8 - 50 - 400

25 cents - 4 - 40 - 160
There are 1280 totals coins


l = a single roll
Redone Table = means it's more exact

The data shows that there are 1280 coins in the American jar.

(Canadian Jar)

Money - Rolls - Value
1 cent - l,l - $1

5 cents - l,l - $4

10 cents - l,l - $10

25 cents - l,l - $10

$1 - l - $25

$2 - l - $50
= $100.00

Redone Table

Money - Rolls - Coins/Roll -Total
1 cents - l,l - 50 - 100

5 cents - l,l - 40 - 80

10 cents - l,l - 50 - 100

25 cents - l - 40 - 40

$ 1 - l - 25 - 25

$ 2 -l - 25 -25
There are 370 total coins

My conclusion states that there are 370 coins in the Canadian Jar.

____________________________________________________________

This is question is about...

How long will it take to fill the jar, if you put 1 coin in pair day.
The catch is that you start on January. 1 . 2010.

A full jar has about 1707 coins. If you round 1707 to the nearest hundred it would be 1700.You can find out one tenth of the jar by dividing 1700 by 10.One tenth of the jar would have about 170 coins. If you multiply this by 2 to get 2 tenths or 20 percent you get 340. 370 coins would fill up a little bit more than 20 percent or 2 tenths of the jar.


This is what I think the answer would be.

Thanks to Jomari for the help.



p.s. sorry if it looks messy.

BOB, bruce8-16. graphing

Graphing Information

3 Things I Know About Graphing.

• you need to have a x-axis and y-axis.
• your y-axis intervals have to go up by the same order.
• you always need to label the x-axis and the y-axis with a title.

I could have improved my test by properly labeling the x-axis title. For example instead of labeling it Groups I could have label it Numbers Rolled.

This is what Mr. Harbeck told us to do in class.

PLEASE COMMENT!!!

bruce's scribepost, the four 4s

Hi guys,

Today Mr.harbeck told us to state how (4+4) + (4+4)=2 is the same as 4/4 + 4/4+2.

My thoeryis that the 4+4 part and the 4/4 part each represent a whole. So which means that if you were to double each of them it would equal 2 wholes. So that's why we have 2 as the answer because it represents 2 wholes.

e.g. (4+4) = 1 whole
(4+4) = 1 whole
1 whole + 1 whole is 2 wholes.

4/4 = 1 whole (because 4 quarters would equal 1 whole)
4/4 = 1 whole
1 whole + 1 whole is 2 wholes

That's what I think makes this 2 statements the same.

Bruce's scribepost, sept 29.09

Hi guys,





Today Harbeck told me to make a scribe on what we've done in our foldable.


















1.1 Advantages of different graphs



Bar Graphs- are good for comparing data across time.





Double Bar Graphs- are good for comparing two types of data across time.





Circle Graphs- are good for comparing data to the whole using percents. The percents have to be out of 100%.





Line Graphs- are good for showing changes across time.





Pictographs- are good for comparing data that can be easily counted and represented by picture data.





* I couldn't find a picture with exactly all the graphs (Double Bar Graph) in it so I just used the picture above.

___________________________________________________________________


1.2 Misrepresenting Data

A break in the y-axis of a graph means the length of the axis has be shortened. The break can be show as...

Some other ways you could do this to other types of graphs could be...

-Distorting the visuals which would be good for a pictograph.
-Distorting the size of bars which would be good for a bar graph.

here's where you can go to find the other ways of misrepresenting data.

Just to make it easy go to mytextbook.ca, section 1.2 and find pages 19 and 20.
Here you will learn how to misrepresent data.
