2 Minutes to Make a Difference Final Reflection

Google Docs

Version 1








Final Cut









Please relect and talk about the changes you made between the first and final cut of your movie. Were the student comments helpful in making your final cut better?
How did you find your expert? List 3 important points your expert added to your movie. What did you learn from your expert?
In the first version, the voices weren't that clear and we still needed an interview. In the final version we made the voices more clear and we ask for permission from someone who had interviewed an expert. The experts name was David Suzuki. One thing I learned from the our expert is that it is not too late to make a difference. Another thing I learned is that scientists are already trying to find ways to stop this problem. The last thing I learned is that even though we can reduce of greenhouse gases we can't remove the damage we have already done.

What was your greatest success in the 2 minutes project. What skills will you take away with you and use in the future?
Some skills I will take away are giving people credit for their work and asking for permission such as using cc pictures and asking permission for information. Another skill I will take away will be the ability to use iMovie and converting movie files.

What frustrated you during the movie making process? What strategies did you use to become successful?
Something that frustrated our group was the fact that the person we were suppose to interview wouldn't respond and we solved the problem by asking permission from someone else to use part of an interview they had with David Suzuki.

Why is the 2 Minutes project important to Grade 8 Students?

I think that the 2 Minutes to make a Difference project is important because at this stage of like we are not aware of all the things happening in the world. The project helps students learn about the outside world and how fortunate we are. If every student made a difference at least one time in thier lifetime, the world could be a better place.



How will you make a difference in the future?
I will make a difference in the future by doing simple things that make a differences such as using the 3 r's and reduce the use of the car. Another way I will make a difference will be by using composting bin. I will also use recycling bins because I have one in my house and it has reduce a LARGE amount of garbage in my trash can. Another way I will make a difference is to encourage lots of people to help make the world a better place.

Ralph's Fraction Growing Post











a) Here is a video of how I got my answers on my fraction test.






























































b) Next, I will explain two ways to multiply a fraction by a whole number using a question from page 202.




One way you could solve the problem is drawing a diagram to show how you did it.




Another way you could solve the problem is multiplying the numerator of a fraction by the other fractions numerator and multiplying one fractions denominator by the other fractions denominator.




eg. 6 x 1/4


































c) Next, I will explain how to divide a fraction by a whole number using a question from page 208.






When you divide a fraction by a whole number one of the best ways to solve the problem is with a diagram.




You draw the original fraction, then you make a fraction of that fraction.






eg. 1/4 o/o 2 = 1/8





So you take 1/4. Then you split 1/4 in two. So you end up with 1/8. You get 1/8 because you have to divide all the 1/4's into two so there would be 8 pieces.


























d) Finally I will solve one word problem from page 208.


7. A pitcher of orange juice is 2/3full. If four students equally share the juice, what fraction of the full pitcher does each student get?




The question is asking us 2/3 o/o 4 students.



This is how I got my answer:










































First I drew 2/3. Next, for each third, I split each one of them into 4th's. Next I filled in 2 squares because the original fraction was 2/3.






When you count up all the squares, there are 12 squares.




The fraction is 2/12.
Each Student gets 2/12 of the juice.





Thanks for reading!


PART 2 !

Fraction x Fraction

When you multiply a fraction by a fraction, you multiply the two numerators and the two denominators to get a new fraction.








eg.




























































































Fraction x Mixed Number
When you are multiplying a mixed number by a fraction you convert the mixed number by multiplying the whole number by denominator then adding the numerator of the fraction. Then you multiply the two numerators and the two denominators.
eg.






















































Mixed Number x Mixed Number
When you are multiplying mixed numbers by mixed numbers, you convert the mixed numbers by multiplying the whole number by the denominator then adding the numerator of the mixed number. Then you multiply the two numerators and two denominators. Next you convert the new fraction back to a mixed number if the fraction is really big and can't be simplified.





eg,




































PART 3




Today we wrote down how to divide fractions and mixed numbers. We also had to answer 2 questions.


1 1/2 -/- 3/4


Which means "How many 3/4 in 1 1/2."


This is how I got my answer




3/4 -/- 1/2


Which means "How many 1/2 are in 3/4"


This is how I got my answer

Ralph's Surface Area Growing Post


Rectangular Prism:





To find the area of a square you use this formula









a= lxw









Using this formula I can find the area of a rectangular prism. First I have to make a net of the rectangular prism then I use the formular for each face on the prism. After I find the area of all the faces I add them all up to get the Total Surface Area.









TSA=50+50+30+30+15+15









TSA=190cm(2)










Triangular Prism:









To find the area of a triangle you use this formula









a=lxw/2








Using this formula I can find the area of a triangular prism. First I have to make a net of the triangular prism then I use the formular for each face on the prism. I used the rectangular prism formula when there was a square and used the triangular prism formula when there was a triangle. After I find the area of all the faces I add them all up to get the Total Surface Area.















TSA= 1.89+0.98+1.61+1.61+1.61





TSA=7.7cm(2)




Cylinder :







For the cylinder you use 2 formulas.







To find the circumference you use this formula. C = pi x r x r




If you need to find the area of the circle you use: a = (pi) x d








Using this formula I can find the area of a triangular prism. First I have to make a net of the cylinder. Next I used another formula to get the diameter of the cyclinder (which would be r x 2 = d). After that I used the radius to calculate the circumference. Next I used the diamter to find the area of the circle. Next I used the rectangular prism formula to figure out the rectangular part of the net. Finally I added the 2 circles and the rectangular part of the net and got the TSA.













TSA=314+314+1381.6







TSA=2009.6

Scribepost for February 2 2010

Today in class, we filled in 4.4 in our foldable and we some questions in our textbook.
I was assigned number 5 and 9.
5. Ravi purchased 3 DVDs for $19.99 each.
Find the total cost for the DVDs including
5% GST and 6% PST




I rounded $19.99 to $20.00 because it was an easier number to work with. They I multiplied $20.00 by 3 because Ravi bought 3 DVDs.


I combined 5% and 6% and made 11% in tax


First I found 10 percent by dividing by 10.


Then I divided by 10 again to get 1 percent.


Finally I added 1% and 10% and got 11%


The final price of the DVDs would be $66.60
9. Arjay was thinking of buying a car worth
$23 000, but delayed purchasing the car
for a year. During that year, the cost of the
car increased by 3.2%.

a) What was the price of the car when
Arjay purchased it?





First I found 10 percent by dividing by 10.
Then I found 1 % by divding by 10 again.
Finally I divided by 10 one more time to get 0.1% and times by 32 to get 3.2%
The final price would be $23000.00 + $736.00=
$23,736.00







b) What was the total cost of the car
including 5% GST and 5% PST?
5% + 5% = 10%
To get 10% I divided 100 by 10
The final price with all the taxes and the current price would be $26,036.00

Scribepost For January 6 2009


Today Mr. Harbeck said that if we haven't scribe yet we should pick a question. Here is question number 7.


7. What is the height of
the wheelchair ramp?
Give your answer to
the nearest tenth of a centimetre.
c² - b² = a²
80² - 79² = a²
(80x80) - (79-79) = a²
6400 - 6241 = a²
159 = a²
√159 = √a²
12.6cm= a
The wheelchair ramp would be 12.6 cm tall.

Ralph's Pay It Forward

Part 1
I think Pay It Forward is a very good idea. If people start helping others, then they will help even more people. If the news spread, then even more people will start being nice to everyone else. Eventually, you could get thousands to ten thousands to one hundred thousand people. The amount of people that could get involved are endless. Everyone should do their part to do something incredible.


Part 2 For Pay It Forward project, we did two things. First we donated clothes to Salvation Army, then we gave cards out to strangers at Polo Park. We chose this activity because people should be happy during Christmas season. We helped people that need clothes at Salvation Army and we helped people at Polo Park by putting a smile on their faces. As I said before we donated clothes at Salvation Army and gave cards out at Polo Park.
We finished our random act of kindness on December 3 2009

Blogger would not let us post the video so we burned it on a DVD. I hope that is alright..

Part 3


For Pay It Forward project, we did two things. First we donated clothes to Salvation Army, then we gave cards out to strangers at Polo Park. When we gave our stuff to Salvation Army, they thanked us and then we left. Next we went to Polo Park and gave out cards to random people. Some people took them, smiled and thanked us. Other people were mean and pretended we weren't there. I felt really good giving things to other people because it made other people smile. Some people reacted well and thanked us, while others just walked past us. We didn't ask people to pay it forward because we weren't sure if people would even take the cards and if people would take it seriously and pay it forward to others.



Part 4
The idea of "Pay it Forward" is important because there are so many things you can do to make a difference in the world. I think our act of kindness made a difference in at least one persons life that day because we made most of the people smile.

Ralph's Number line Scribe Dec 2

Today in class we had to either finish our number line or do several questions in the book. My scribe will be about the number line.

Here are pictures of my number line.
On my number line, it shows the area for numbers from 1 - 25.
Not every square was a perfect square so I outlined the perfect squares in picture.
Some patterns I found out about the number line is that the amount of numbers between each perfect square is always even.
eg. 1 [2 3] 4 [5 6 7 8] 9
I also figured out that the amount of numbers until each perfect square is always odd.
eg. 1 [2 3 4] 5 6 7 8 9]
*purple = perfect square
Thanks for reading my post!
Sorry that it doesn't look the best.

How I Saved The World From Aliens With Proportion

I was fast asleep in my nice and cosy bed when suddenly, the was a big BANG! A UFO had landed in my backyard. When I went to go check it out, the was already an alien with a laser gun pointing at me. It told me if I didn't tell him and answer three proportion questions, he would blow up the earth with his giant satellite laser cannon in out space and make the leftover debris into a UFO parking space. I had to act quickly so here are the questions :


6. Delia was paid $35 for 5 h of babysitting.
How much should she receive for 3 h?
Use a unit rate to find the answer.











So the rate would be $21/3h




12. Set up a proportion for each situation
using a variable. Do not find the answer.
a) Walter makes his own oil and vinegar
dressing. His recipe calls for 175 mL
of olive oil and 50 mL of vinegar. What
amount of vinegar does he need to mix
with 300 mL of olive oil?







b) A baseball player has a home run to
strikeouts ratio of 3 : 17. How many
home runs should he hit if he strikes
out 187 times?











By the time I answered the second question, the alien seem to be getting nervous. It must have visited earth before because it learned to speak in our language. It said "You may have answered 2 questions but you cannot possible finish 3!" I laughed and began to solve the last problem.




Question 3


Two quarters has the same value as ten nickels. What is the values of five quarters in nickels?
















There are 25 nickels in the value of 5 quarters.


The alien couldn't believe I answered all the questions. It said " You have answered all the questions but, an alien never loses!" The alien blasted his gun. The laser sliced a tree in half. Next the alien said " BWAHAHAHAHA ! I'm going to blow up your puny planet anyway! It fired the laser at me but, I dodged it. It just barely trimmed off a piece of my hair. Then, I searched my pockets, found a bag of original skittles and said " Go back to your own planet!" I opened the skittles bag, ate a handful, and rainbows came out of my eye sockets! The rainbows hit the alien space ship and it turned into skittles. Another spaceship hovered over my backyard and took the alien back. The aliens last words were " I'll be back to challenge your knowledge in math again!" That's how I saved the earth by using proportion and skittles!


The End.


I hope I did this post right. Sorry the ending didn't have to do too much about math. I got a little carried away with the story.

Ralphs %%%%%'s Rate Growing Post

Today we had to do part one of a two part post.




Define ratio




Ratio: Compares two things of the same quantity.







eg. 3:4 7:8







Rate: Compares two things measured in different units.







eg. heartbeats : seconds





Questions:





4. Determine the unit rate in each situation.
a) An orca swims 110 km in 2 h.



2h / 2 = 1h 110 km/2 = 60 km 60km/h



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


12.5 h / 12.5 = 1 800/ 12.5 = 64 64km/h



c) Cathy plants 45 daffodils in 30 min.





30min x 2 = 1h 45daffodils x 2 = 90 daffodils 90 daff/ h






10. Trevor rode his mountain bike 84 km in
3 h. Jillian rode 70 km in 2.5 h. Who is
the faster cyclist? How do you know?






They are both going at the same speed because if you divide 84 by 3 you get 28 and if you divide 70 by 2.5 you still get 28.

Coin Question


If the jar was Canadian, worth 100$ and had 460 coins, what would be the unit rate for each dollar?


Answer:


$ Coins
_____________
$100 460 coins
/ 100
$1 4.6 coins rounded 5 coins



Part 2

I dont know why but, my image won't go on to my post so I'll just do the work anyway.


To find ingredients for 10, you need to multiply the recipe by 2.5. 4 x 2.5 = 10

Recipe for 10 people.

1 1/4 lb ground beef

2 1/2 medium onion diced

2 1/2 celery finely sliced

2 1/2 clove of garlic

35 oz can of tomatoes chopped

1 1/4 can of tomato paste

2 1/2 tsp parsley

3 3/4 tsp basil

2 1/2 tsp oregano

2 1/2 tsp sugar

1 1/4 tsp Worchestershire Sauce

1 1/4 tsp seasoning salt

2 1/2 bay leaf

You can get recipe for one by dividing all ingredients by 4.

Recipe for 1 person

1/8 lb ground beef

1/4 medium onion diced

1/4 celery finely sliced

1/4 clove of garlic

3.5 oz can of tomatoes chopped

1/8 can of tomato paste

1/4 tsp of parsley

7.5ml / 0.375 tsp of basil

1/4 tsp of oregano

1/4 tsp of sugar

1/8 tsp of Worchestershire Sauce

1/8 tsp of seasoning salt

1/4 bay leaf

Ralph and BOB Ratio October 20 2009



Today in class we did alot of work with dealing with ratios. Our homework today was to do a post that had:


3 part to part ratios, 2 part to total ratios and 2 three part ratios


Then I had to:


write that ratio in ratio notation, fraction, decimal and percent form.


Next I would have to:


pick one and show how to create equivalent ratios.


Finally create 3 questions that you want people to answer in the comments. Do not make them to hard or too easy.




Part to Part Ratios
Green to Blue=7:1
Red to Green=6:7
Red to Yellow=6:4

Part to Total Ratios
Red to Total=6:18
Blue to Total=1:18

Three Part Ratios
Red to Blue to Yellow=6:1:4
Red to Blue to Green=6:1:7


Converting Ratio to a : Fraction, Decimal, and Percent

Red to Total : 6:18 or 6/18 or 0.33 (Infinite) or 33.33(infinite) %

Simplifying Ratios

6:18 simplified would be 1/3
6 (divided) by 6 is 1
18 (divided) by 6 is 3
6:18 = 1/3 = 0.33(infinite)


THE 3 QUESTIONS!!!

1. Express the ratio Yellow to Red in a Ratio, Fraction, Decimal, and Percent.

2. What would the ratio be if the Yellow to Red ratio if the ratio was simplified.

3. What would be the ratio of Red, Green, Blue, Yellow: Total

Thanks for Reading!
Don't Forget to Comment!
ANSWER MY QUESTIONS!
Some mistakes I made on my test were that:
1)I didn't read the questions well enough.
One question was about votes for student council.
The part I didn't read well enough was that the ratio had to be GIRLS to BOYS .
The ratio I put was boys to girls so I got the question wrong.
2)I should find more easier and faster ways to solve harder equations.
For question 17 I had to find out what two teams were equivalent.
I spent alot of time looking for a number that I could multiply the two numbers by, when I could have,
divide the first number by the second number and see which ones match.
3)I need to always go over the test again in case I missed a question.
I could of gotten more marks if I read over all the questions. Question number 16 was a really easy question but I accidentally skipped it and went onto the next question.
QUESTIONS
1. A picture frame has a width to length ratio of 10:14. If the width of the photo is 18 cm , the length of the photo is _______
a) 22 b)25.2 c)28 d) 32
2. A stable has 78 horses. Of these horses, 52 are brown, 16 are white and the rest are black. Express the ratio in the lowest terms of brown to white to black horses.
a) 26:4:5 b)13:4:2 c) 52:16:10 d) 26:8:5

Ralphs Ratio Scribe Oct 18

On Friday we were each assigned some questions for math.
My two questions were:



7. Write each ratio in fraction form. Do not
write the answers in lowest terms.

a) You spend $4 out of $10.


If you spend $4/$10 then the fraction would be 4/10


b) A team won three games and lost six
games. What is the ratio of games won
to games played?




If the team won 6 games and lost 3 games then

the ratio would be:


win:lose = 6:3



c) A bag contains 12 red and 3 blue beads.
Compare blue beads to total beads.




If you compared the blue beads to the total,

the ratio would be,



blue:total = 3:15


d) A pond contains 27 guppies and 33
goldfish. What is the ratio of guppies
to total fish?




If you compared the guppies to the total fish the ratio would be:

guppy:total = 27:60




a) 1/2 is also equal to 4/8

b) 4/5 is also equal to 12/15

c) 2/7 is also equal to 6/21

d) 1/4 is also equal to 3/12

e) 21/49 is also equal to 3/7

f) 4/5 is also equal to 12/15

Ralph 817 Oct 14 Scibe

Today we learned about ratios and things dealing with ratios. We had to write down some keywords for our foldable .

The words were:
Two-term ratio
Three-term ratio
Part-to-part ratio
Part-to-whole ratio
Rate- Unit rate
Unit place
Proportion

Two-term ratio means comparing two quantities measured in the same units.
eg.
12:24 or 12 to 24
Three-term ratio means comparing three quantities measured in the same units.
eg.
1:2:10 or 1 to 2 to 10

Ralphs Coin Math Oct 9 09 part 1 and 2




Todays assignment was to answer one purple and one of any other colour.




1.Would the jar look the same if it was Canadian money




The jar wouldn't be the same because there are pennies, nickels, dimes, and quarters in both Canada and America but, Canada also have loonies and toonies which are pretty big and can take up alot of space too.






2.What is the value of each type of coin in a jar.



On a website I found out that
Coin rollers contain the following:
50 x $0.01 = $ 0.50 = a penny roll

40 x $0.05 = $ 2.00 = a nickel roll
50 x $0.10 = $ 5.00 = a dime roll
40 x $0.25 = $10.00 = a quarter roll
25 x $1.00 = $25.00
25 x $2.00 = $50.00



So you could put :
80 rolls of pennies = $40.00
10 rolls of nickels = $20.00
4 roll of dimes = $20.00
2 roll of quarters = $ 20.00
= $100
Considering the fact that its American coins.

I hope that the answer is something on the lines of this chart.









"Coins Part 2"


Our part 2 of our coin math was an assignment.



1. a) Make a combination of USA coins



80 rolls of pennies = 4000 coins = $40.00

10 rolls of nickels = 400 coins =$20.00

4 roll of dimes = 200 coins =$20.00

2 roll of quarters = 80 coins = $ 20.00

= $100



b)Make a combination of Canadian coins

*Must use a roll of each coin.*



If Canadian coins are,



50 x $0.01 = $ 0.50

40 x $0.05 = $ 2.00

50 x $0.10 = $ 5.00

40 x $0.25 = $10.00

25 x $1.00 = $25.00

25 x $2.00 = $50.00



Then you could put



1 roll of toonies = $ 50 = 25 coins

1 roll of loonies = $ 25 = 25 coins

1 roll of quarters = $ 10 = 40 coins

1 roll of dimes = $ 5 = 50 coins

4 rolls of nickels = $ 8 = 120 coins

and 4 rolls of pennies = $2 =200 coins

= 100$ = 460 coins



2. How full is the jar?



If the jar was originally about 75 percent full

and there were about an estimate of 20 rolls or 1350 coins according to other classes work

According to my work, the jar would about 30% full and the jar also has 460 coins.



How can you use a ratio table?



If the information was put on a ratio table it could look like this:






I'm not sure if that's how you make the graph with the information so I just put information on the graph.

Ralphs 4 Fours Scribe



















Sorry I uploaded this post really late.
What we were suppose to do for homework was explain how both of the equations were the same.
The similarities are that:
- They both equal the same number
- The signs both mean the same thing except show differently
Sorry it was late !

Ralph's BOB October 6

What do I know about graphing?






1. I know that there is an x and a y axis on a bar graph.





2. I know that the intervals on the y axis must stay the same all the way up.

















3. I know that there are several different types of graphs




What did I miss on my assessment?
1. One thing I did wrong on the assessment that I should have done was that I was also suppose to put a T - Chart when I was suppose to organize data.
2. Another thing I was suppose to do was to also put trends
3. The final things I had to do was put was two ways why distorted a number and two ways
how I distorted a number.
Thanks for reading my post ! Please leave a comment !

Ralph Scribepost for September 30 09



2. a) Sophie surveyed her friends about their
favourite flavour of ice cream. What
information is missing on the graph?


The information missing is the amount of people the graph is out of !



b) How could you present this data more
accurately?


If you knew how many people the graph is out of, it would be more accurate.

To make it even more accurate you could even make it into a bar graph.



3. When might it be to someone’s advantage
to present distorted data? Share your
answer with a partner.


If someone REALLY loved a certain flavour they could make the flavour really stand out by distorting it.

eg. Bright Colour, Make the number larger, etc.
