The Story of Stuff: A Critical Analysis Answer questions in even number

2. What audiences do you believe Annie Leonard is trying to reach?

I think that Annie Leonard is trying to reach audiences who never recycle, always waste a lot. She was trying to reach all the people who are not aware about he problem-- including the people who doesn't know how the government and large companies are ruining our environment, and our community.

4. Why do you think Annie uses the format of a 20-minute video rather than another format, such as a report, web blog, or poster?

I think that video is better than any of the other ways is that videos can kind of let the audience feel that they are interacting with the person inside the video. With the use of  language such as "we all know"， or "maybe you don't know", Annie was able to let people truly know that they should be with her and their views has been changed. 

6. Who might disagree with Annie’s message? Why do you think they would disagree?

I think that the people from Government or large companies might disagree with Annie. They profits that they need to maintain, they don’t really want people to know the truth of their darkness of the business, and they don’t want their profit to be affected.

8. Has the story of stuff affected they way you think about consumption? If so, how?

The story truly affected they way I think, it’s the first time I ever heard about the pillows we brought home could be extreme toxic, and the most toxic substance was found in human breast milk. I now will stand by her side, and I will try my best to tell even more people to start recycling, tell them to reduce their daily waste, and save the earth.

Which fact was most surprising to you? Why?

The fact that “99% of the stuff that we create on planet earth I thrown in the garbage within 6 month” was most surprising to me. After I heard this information, I was shocked! After that, I recalled everything we are using in the daily life, food, daily uses, such as the coffee cup, pizza box, paper, or even electronic products such as earphones, most likely going to be thrown away within 6 month. It is true about we are over using earth’s resources, and there are just not enough for everybody if we keep living this kind of life style. We should stop this kind of life style, to give our children a better world.

Biology Question & Answers for Video Worksheet"The Cove"
My birthday is the 28th, so I'm posting the even number questions.

2. Taiji,Japan

4. The death, more precisely the "suicide" of the dolphin "Flippers".

6. Japan indirectly runs the TWC, because they give the other little island countries benefits to let them support Japan's dolphin industry.

12. Mercury was found in dolphin meat

14. The Japanese government use media to lead people away from the situation and covered it up.

16. The cause is that people are over fishing, statics shown that we will run out of sea fish in 40 years.

18. They tell people that it's actually whale meat.

20. The main character goes to the IWC and carried a screen performing the video tape they filmed in Taiji, the video of the sea run red because of the dolphin's blood.

Biology population lab Questions- sept 6, 2014

Today in Biology Grade 12 class, Mr. Chung told us to do a lab called "Mark-Recapture Sampling" Lab to help us understand the method of Mark-recapture more.
It's Super fun!

1. compare your estimate of the size of the pasta population with the true size. how close were you?
 In the lab, we calculated that the population size twice, the first time the result was 1800, and the second time the result was 714,the average of them was 1257. After we counted the pasta one by one it turns out that the actual population was 615. We were 100% higher than the true population.


2.(a) What problem you think might affect the accuracy of your estimate?

For the first time, we thought that the total amount of pasta would be around 3-4 hundreds, so we took 40 of them out, and then we marked them. We shook them to mix it up.

Later on when we recaptured them, we recaptured 45 of it, but only 1 of them were marked, and we calculated the number that it has 1800 in total.(picture) We did one more trial, this time we took 100 of it, and marked it with a different mark. We recaptured exactly 100 of it and we got 14 marked, through calculation, we got that there's 714 in total. comparing to the real number, the first time was three times off, even the average was 100% off, but the second time was only  16% off. We decided to only take the second time and mark the first result as an outlier.
I think that underestimating the total population might affect the accuracy of the estimate. Because of the mistake, we captured and marked too little individuals. Also, later when we were shaking it, we only shook it for a few times, so when we recaptured, the marked ones were only in a small percentage, and made the result estimate population super big.
(b)
This activity was not completely valid in that the population was non-mobile. What problems might ecologists studying animal populations encounter?

For this Lab we did in class, we are in a controlled environment, so that we can try to count out every single one of it to gt he real population number. But in reality, scientists cannot count the real number of the population. Also, for the number of capturing individuals, there might not be enough marked ones. Since scientists must guest the real population. And that might results in a large flow in the result.

3. How might you improve your sampling design?
When capturing the sample, we need to wisely control the size, it would be good for around 15-20% of the total population.Because the first time, we only chose less than 10% of the total population, so we got a outlier. Next time, we will have to experience to guess the population before trails more clear to improve the sampling.
