Final Cut



The changes we made between our Version 1 video and our final cut is that we added pictures to our second video. We also fixed up our scripted. The students comments mostly told us to add pictures and as you can see, we have put pictures.


How did you find your expert?
List 3 important points your expert added to your movie. What did you learn from your expert?

We found our expert by looking up " Environmentalist in Winnipeg ".

- He told us information that we had never known before.
- He taught us that their is a plastic dump in the middle of the pacific ocean
- He told us how he would make a diffrence

We found our expert on the Internet .

This movie project in general was a great success. I think our groups greatest success was finishing up our video. This Movie project showed me that things I should careful about and things I could get.

The main problem in our movie project was getting everything to fit together, like we were having problems with getting the pictures, sound, and our voices to fit all together. We ask teachers and students.

I think the 2 minutes to Make a Diffrence was important to us grade 8's because we learned bits and peices about the our world. Everyone had diffrent topics and we learned more about poverty and our environment.

In the future I will make a diffrence by telling people about what is happening in our world and how we can stop it. I will try not to harm our environment.

another way:

Divison Fractions!

1

- divided by 2

The areas of Saskatchewan,Alberta and Manitoba are approximately equal. The sum of their areas is about 1/5 of the areea of Canada. Express the area of these provinces as a fraction of the area of Canada.

1/5 divided by 3 because there are 3 provinces.

Answer :

1/15

Simple sentence answer

Each province cover approximately 1/15 of Canada

Karra's Percent scribepost

Question 1.

Chris purchased the following items:

• 2 Binders for $4.99 each
• 1 math set for $3.99
• a backpack for $19.99

find the total cost including 5% GST and 7% PST.

My answer is ..

Question 2.

A store discounted items by 50% off the
original price one week. The following
week an additional 10% was taken off the
already reduced price. The regular price
of a CD player was $85.00. What is the
reduced price in the second week?

My answer is ..

Question 3

Describe 2 ways you could calculate the total tax of an item?

In my opinion i would use a ratio table. My other way is by using a formula where you multiply the original number by 100 or more.

Karra, Jasmine and Stephanie Pay it Forward

Heey! (:

Part 1

What is "Pay it Forward"?

Pay it forward to me is about helping unfortunate people and making people feel like their important. Most people have money and food and some people can't afford things. People think that they have nothing going for their future but one person can change everything. Mostly everyone has a household and parents that care for them. Their is some people that don't have a family that care for them.

Part 2

What was your Pay It Forward act of kindness?

My group and I Payed It Forward by handing out cards and and suckers to people we saw.
Why did you choose this activity?

We choose this activity because we wanted to show people that not all people are rude and mean. To the people to we gave cards to I hope we made their day better by giving them cards and a little treat.

Who did you help?

We helped a lot of people by giving them cards and a little treat.

What did you do?

My group and I decided to hand out cards and give out suckers to people that we saw walking around and that looked sad.

When did you do you act of kindness?
My group and I did our activity on December 7 ,2009

Part 3

How did your act of kindness go?
Our act of kindness went way better than we thought. It was so much fun handing the cards out. Everyone was so happy when we gave them cards.

What Happened?

Most of the people excepted our cards and were very excited when we gave them. When we were giving out cards a boy came up to us and asked us if he could have one, we were pretty shocked when he came because we were happy that a boy actually wanted to pay if forward.

How did you feel?

I felt really happy when people excepted our cards and were happy that they got a card. I felt really good when people gave us nice comments and how they gave us a big smile.

How did the person or people react?
Some people enjoyed that we gave them a card and treat and some people looked at us like we were crazy. I think the reason why they thought we were crazy was because we were talking pictures and videos.

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

When we gave people the cards we told them to " Pay it Forward" and "Merry Christmas. " We also wrote it on the cards so if they didn't hear us they could see it on the card.

How did they react to your request?

Most people looked very grateful that we gave them a card and I think some people didn't except it because we had a camera.

Part 4

Why is the idea of "Pay it Forward" important?

I think it is important because we made people happy and hopefully made their day better. Some people we gave cards to looked like they were not having a great day and when we gave them a card they looked really happy.

Has your act of kindness made a difference?

I think our act of kindness made a huge difference because people we gave cards to looked like they were not having a great day and when we gave them a card their face lite up with happiness.

Questions 11 and 13 !

Heey (:

11. What is the square of each number?
9 and 11.

First you have to times 11 by 11 because you have to find the square of the number, Which makes the area of the square 81.

9=81

For the 11, you have to times 11 by 11 which makes you get 121.

11 = 121


13. What is the side length
of the square?

The side length has to times a number by a number to get the area.
So what number times itself gives us 49?
The answer is 7!
So 7 x 7 =49 so we put 7 as the measurements.






















The homework for today is to do the number line and the text book work !!

How I stopped an alien invasion using proportion

Okay so apparently there are some aliens on the world and be have to stop them by using 3 proportion questions on them, so here are my question and answers...

1. Question 20.

A breakfast cereal contains corn, wheat,
and rice in the ratio of 3 to 4 to 2. If a
box of cereal contains 225 g of corn, how
much rice does it contain?

Answer :

It contained 150 g of rice.

The reason why I multiplied by 74 is because 3 times 75 gives you the answer 225 . Whatever you do to one side you have to do to the other.


2. Question 5.

What is the unit rate in each?

a. Two pens cost 94¢.

b. Four blocks stacked one on top of
the other are 24 cm high.

a.








b.









Sorry I don't have one for page 69. I went up to 24 but I didn't get the answer(s).

I've saved our planet from some of the aliens (:

Karra's Rate growing Post

Ratio- A ratio is 2 or more quantitees that are compared in the same units.

Rate - A rate is 2 quantities that are compared in diffrent units.


One diffrence i think is that a ratop compares 2 things in the same unites and a rate is compared in 2 things in diffrent units.

Page 60.

Number 4.

a) A Orca swims 110 km in 2 hrs.

Answer: You can use a ratio table but i wont draw one. So for this question you have to divide 110 by 2 that =55. So our unit rate would be 55 km/hr.

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

Answer: You divide 800 by 12.5 which =64 km/hr.

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

They are both the same.How I know is because I..

calculated 3 divided by 3 to get 1. If you do one thing to one side you have to do it to the other. So I divided 3 by 84 and got 28.

on the other ratio table I divided 2.5 by 2.5 to get 1. Since I did it to one side I have to do it to the other. So I divided 2.5 by 70 and got 28.

Part 2)

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

1)1.5 divided by 4 =o.375 multiply by 10 to get 3.75

3.75 lbs ground beef

2)1 divided by 4 =0.25 multiply by 10 to get 2.5

2.5 medium onion diced

3) 1 divided by 4 =0.25 mulitply by 10 to get 2.5

2.5 celery finely slice

4) 1 divided by 4 =0.25 multiply by 10 to get 2.5

2.5 cloved of garlic

5) 14 divided by 4 = 3.5 multiply by 10 to get 35

35 oz can of tomatoes chopped

6) 1.5 divided by 4 =0.375 multiply by 10 to get 3.75

3.75 can of tomato paste

7) 1 divided by 4 =0.25 multiply by 10 to get 2.5

2.5 tsp parsely

8) 1.5 divided by 4 =0.375 muliply by 10 to get 3.75

3.75 tsp basil

9)1 divided by 4 =0.25 multiply by 10 to get 2.5

2.5 tsp oregano

10)1 divided by 4 =0.25 multiply by 10 to get 2.5

2.5 tsp sugar

11)1.5 divided by 4 =0.375 multiply by 10 to get 3.75

3.75 tsp Warcestershire sauce

12)1.5 divided by 4 =0.375 multiply by 10 to get 3.75

3.75 tsp seasoning salt

13)1 divided by 4 =0.25 multiply by 10 to get 2.5

Thanks for reading my post.

Karra's Backscribe post, october 14,2009

Today in class we learned about 4 new ratios.

The names of them are...
Two term ratio-- Compares two quantities measured in the same unit's.
Written as ( a:b or a to b)

Three term ratio's - Compares three quantities measured in the same unit's.
Written as (a:b:c or a to b to c)

Part to part ratio's - Compares different parts of a group to eachother.

Part to whole ratio's - Compares one part of a group to the whole group.


We learned that the symbol ":" can also mean "to" . They both mean the same thing when it comes to ratios.

Karra's Coin Math October , 13, 2009

For our homeowrk we had to pick 2 questions.
The questions i choose are:

1. Does it matter how many pennies there are in a jar?

To me it does matter because you can compare the pennies by the total of all the money in the jar. Total of coins in the jar are 100 so If there are 100 coins, there are proabably 1/4 of pennies in the jar.

2. How full is the jar?

I think the jar is 75% full or 3/4. I divided it in 4 groups and it's not filled up to the top.

Sorry i forgot how to put a picture. (:

Leave a comment! (:

Part 2

1. How full was the jar?

I think the Canadian jar is 1/4 because 1,280 is 3/4 so then i divided 1,280 by 4 . Then i got 320. So i think the jar is 1/4 full.

2. How long would it take to fill the jar if you put one coin each day?
You have to start on January 1st, 2010.

-If your using 1 cent i think it would take 27 years or 118 days because i divide 100 by 0.01 and the amount was 10,000 days.Then I divide 10,000 by 366 days per year.
The year would be January 1, 2010 to April 28, 2037.

BOB, Karra 8-16 Graphing

Hey, the question today was: What are 3 things that I know about graphing:

1. There are pleanty of diffrent graphs
Ex.
bar graphline graph
circle graph
pictograph
double bar graph
double line graph

2. You always need a title

3. You always need a x axis and a y axis.

One thing I could have done better on my assignment is explaining my graph in the paragraph.

Leave A Comment Please!!

Karra, Four4s

The homework today was to find out how (4÷4) + (4÷4) =2 and 4/4 +4/4=2 are the same.

The reason why I think they are the same is because in the fraction 4/4 and I think of 4÷4 which equals one, and if you add another 4÷4 it will equal 2.

For example,

2 ÷ 2 = 1 chocolate bars2/2 pieces of a chocolate bar would equal one whole chocolate bar, since there is only 2 pieces. In a whole chocolate bar there would be more than 2 pieces of chocolate.I think they are the same because they are both division. You can do both ways and your answer would still be the same.

I’m probably wrong (: LEAVE A COMMENT!!
