You can find a maximum and minimum point for graph Y. The lowest points are the X-intercepts. The points are the lowest when the ball got sent and received.  The maximum point for graph Y is the vertex. Since there are 29 points, the middle of 29, which is around 14-15 should have the highest point. Looking at the graph, 14 and 15 has the highest points. (14,2.314) (15,2.314) (coordinates for the vertex) 

Looking at the Y velocity, there is a maximum and minimum speed. Gravity and air resistant decrease the travel speed of the ball. Therefore, the speed of the ball gradually decreases throughout the movement.   

 

 

We did very well in collaboration. We helped each other when constructing graphs and gave each other useful method when facing a problem. 

We faced challenges when finding the origin. Our videos ended up in different settings. We must find an origin for each, and it was very confusing.  

The video taking process ended up being time-wasting. The teacher should provide the students with videos already taken to save time for the iMovie and explanations.  

I would have taken all the videos in the same setting. It was very confusing when choosing the origin. The photographer had to be in different positions when recording the movement of the ball

Reflection

Our group followed the design process. We had a very solid plan for fixing containers. Everyone took part in our group when constructing the polymer. We all discussed together for the formula of the polymer. When we found problems about the polymer, for example when we found both prototype 1 and 2 not working, we got an alternative for the materials used now. In that scenario, we replaced gloop with bio-plastics and got back on track.

 

We made a story based on a real-life incident where someone actually dropped a bottle and we had to fix it. Although we over-dramatized the “what happened”, the panelists and classmates still understood the purpose of our product. We included the goals, obstacles, and formula for our polymer. One thing to improve on would be to make the presentation more real. By that I mean we should tell a story that is valid. We should decrease the level of entertainment and replace that with some more data collected and that would be more convincing to the panelists.

 

Looking at the ingredients and the feedback of peers, we did a great job of caring for our environment. At first, our group did not have a product that is bio-degradable. Prototypes 1 and 2 used more than 50% of synthetic materials. To improve on that, our group changed our major ingredient from gloop to bio-plastics. As we all know, bio-plastics is 100% self-degradable and does not include any synthetic materials. Our product is definitely sustainable.

C: Compared to other prototypes, prototype 3 (bioplastics) is our most successful prototype

E: According to our testing results, (including the smell, weight, durability, and ability to hold water) prototype 3 has the best ability to hold water. Unlike the other 2 prototypes, prototype 3 used a different kind of material. Prototype 3 weighed the less and has fewer materials contained. Compared to the other 2 prototypes, Prototype 3 does not have an irritating smell. Prototype 3 after the solidifying process turned out to be absolutely odorless. Prototype 3 could hold water as long as the layer of polymer stays. In the testing process, we found out that prototype 1 and 2 would frequently leak because the product itself would become wet when touched with water. However, prototype 3 held water perfectly and did not leak.

R: Prototype 3 is the best prototype. First, we used sustainable materials. Bio-plastics are 100% self degradable and would not leave carbon footprints. We used natural materials instead of synthetic substances. Second, prototype three met all of our goals. It held water and repaired the broken parts of the bottle while having a very cheap cost. Third, prototype 3 lasts longer and has a better outlook than the other two prototypes. Prototypes 1 and 2 are all blue. They are slimy and wet. However, prototype three is transparent. Unless you feel it, it is hard to even spot the product. Concluding all, prototype met all of our goals, unlike the other 2 prototypes. It successfully repairs the damage.

Growth Through Slaughter, Growth Through Fear!

The rich land of Panem lies above the pain of its citizens living across the 12 districts. Each year 1 boy and 1 girl would be elected to participate in a glorious event called The Hunger Games. There is only one survivor and the rest would all sacrifice for their district. The protagonist, Katniss is a courageous, strong, and caring girl.

 

First, Katniss has a courageous characteristic. She devoted herself and volunteered to take the position of her sister. “I volunteer!” I gasp. “I volunteer as tribute!” (Collins, 22) In the story, her sister “luckily” got picked as the tribute for the games. However, her sister was just 12. She was not prepared for such an event. In order to stop this unneeded sacrifice, Katniss volunteered instead of her sister. That shows her courage by volunteering into this dangerous event. Adding on to that, she had the courage to show her ability to the game makers by shooting at them. Some might say that the action was foolish. Her way of showing wrath and power to the game makers is innovative. But it requires more bravery. She was not afraid to make the game makers mad. That earned Katniss sponsor and support in the games. “I hear shouts of alarm as people stumble back. The arrow skewers the apple in the pig’s mouth and pins it on the wall behind it. Everyone stares at me in disbelief.” (102)

 

Second, Katniss is a strong girl. She strived in the games and survived, at last, she overcame the physical pain and physiological fear. In some situations, she got injured severely. Once she got stung by venomous bees but still managed to stand up and continue her journey in the games. “A stabbing pain shoots through my knees and I know one has found me and the others would soon be honing in.” (190) Not only was she stung, she ran into man created fire and got several parts of her body burnt. Yet she still continued until she found a lake and jumped in. “Refreshed, I treat my burns again, braid my hair and dress un the damp cloths.” (199) If she was weak, she could’ve just suicide instead of enduring that level of pain.

 

Third, Katniss is caring. She always cared about the lives of her companions. If Katniss turns to a real person. I can guarantee that she would help you relentlessly. That is a key factor in solid relationships with friends. “And suddenly, I’m not thinking of Gale but of Peeta and…Peeta saved my life.” (196) In that section of the book, Peeta, the other tribute from district 12 that love Katniss, sacrificed himself for Katniss. Katniss really wanted to show gratitude but did not know where Peeta went. Another companion that Katniss had was a girl called Rue. She came from district 7 and helped Katniss with a variety of things, including meals, injuries, and others. However, Rue got killed later in the book by another tribute. ““I can fix your stings.” Said Rue.” (200) “I press my lips against her temple. Slowly, as if not to wake her, I lay her head back on the ground and release her hand.” (236)

Concluding all, Katniss is a courageous, strong, and caring girl. She demonstrated the three characteristics throughout the story. She has grown as a human being throughout the story. From a girl living in the peaceful lands of district 12 to a machine a slaughter. Her change turned out to be huge. She got mature and that sense of naïve no longer remains.

To My Sister

In the book Hunger Games by Suzanne Collins, the protagonist Katniss mentioned her sister frequently. I believe that her sister gave her the motivation to fight. This story is not only a story about fighting and strategies. It emphasizes the love between siblings.

“It’s Primrose Everdeen.” (Collins, 20)”

“I volunteer!” I gasp. “I volunteer as tribute!” (22)

The two quotes show the importance of her sister in her heart. In Kat’s opinion, Prim’s life is superior to hers and she’ll do anything that could prevent Prim from dying.

Ping Yao, The City of Peace, Love, and Prosperity

 

Three things I’ve learned on the train

  1. I learned about Centauri’s hobby of watching anime (One Punch Man).
  2. I learned about Elgin’s diet. He eats western.
  3. I learned about Erick Chen’s ability to do pull-ups. I could do 30 in a row.

 

 

Two things I’ve learned

  1. I learned about Pingyao history. (The show we’ve watched about the Zhao and Wang family)
  2. I learned about Pingyao eating culture. (Ping Yao beef, Ping Yao Vinegar)

 

Successful aspects of the Pingyao Challenge for our group

  1. As a team, we wandered off at first but then realized the importance of teamwork. Our group collaborated well.

The funniest moment

  1. Centauri sleeping. His form looked a bear in hibernation.

 

The most challenging aspect of the trip and solution to the problem

  1. I, Elgin, and Centauri got lost. We communicated with the staff and finally found out way back to the Yi Guan hotel. I used the communication skills mastered in the CLL class.

Most memorable moment

  1. Playing BTS at 9. It represents youth. That night is unforgettable because it was really fun. (Told Jokes)

Recommendations

  1. The students should have more independent time. As of 8th graders, we should have the freedom the play around Pingyao on our own. Going with the school is safe but not that entertaining.
