Nitrogen Cycle 

In class today, we were doing this activity, where Mrs. Smith made us to be cute tiny little nitrogen atoms. We were to travel from stations to stations that were labelled different each. 

Why didn't everybody go to the same station in the same order?

In the real nitrogen cycle, not all of the nitrogen atoms clump up together in a group and travel together. Some of the nitrogen atoms are on one "stations" and some on other "stations".

Did you go to the same  station twice? If so, what does this tell us about cycles?

It tells us that in a cycle, you can go back repeat part of a cycle. 

Was there one station that seemed to have a lot of people at it? Why or Why not?

Yes, sometimes, people roll the dice and have the same number as some other people. Then, people crowd around that area. 

What do you think that the point of this activity was?

I thought that the point of this activity was to let us see how it is in a cycle. And to teach us about cycles, that cycles doesn't have a specific chronological order. You can repeat some of the stations. And, maybe, Mrs. Smith wanted to see Juegan be the poop and see his reaction. :P

Benjamin Button TED Talk

The steps of the scientific method are :
1. purpose
2. hypothesis
3. material
4. procedure
5. conclusion
Making the film went through these steps. They encountered problems like how they were going to make Brad's face look older. The people who were working on the project, had to guess on how they were going to make Brad Pitt 45 years older. So, they tried different ways to make his face look older. The materials they had to have were money, technology and actors. They tried to painting Brad's face with phosphorous and film it in the dark and then process it in the computers. And then made some change it to look older. They they filmed the bodies of different actor as Ben's body. They use the technology to change Brad's face and replace the head of the actors (as old Ben's bodies), with Brad's older face. They also had to have a lot of the faces of 80 year old Brad's in different kinds of light. They also made it look realistic so that it really looks like it is real. The conclusion of the movie was to put it together.

Submarine Smash Day's Reflection.

Smash day stands for "Smith's Marvelous Awesome Hoopla". Smash day is a day where we have activities and "missions" to accomplish. It is on the first science class of a new month. For the February's Smash day, we were to make a periscope that enables us to see from below the table into the box of items that we were suppose to identify. We were given 10 sheets of paper, a piece of cardboard, tape and 5 mirrors. We didn't modify our design, we mainly modified the angles of the mirrors. We knew that we had to modify the mirrors because we could not see from under the table to the top of the table. My group wasn't very cooperative, we didn't discuss our thoughts which made it hard for us to build the periscope. We had to keep asking each other what he/she was doing. And the changes that all of us made were logical. I would suggest to the person who will be doing this "mission", is firstly, when you hold a piece of tape for your group members to cut, speak nicely or yell at him to watch what he cuts on. Secondly, discussion is better when it comes before the construction of the periscope. And thirdly, three people should have jobs to do so that the building of the periscope will be finished in time.
