The Capstone Journey

Through the Capstone project, I gain a deeper understanding of the problems that China has right now. Air pollution is a struggle to many Chinese, as a result to all of the research and interview me and Sam made a documentary about how terrible the problem is right now and why it air pollution should gain attention. After the documentary, I gain knowledge why China is burning coal, why Air pollution is still happening and what can stop Air pollution. If I had the chance of doing the project again, I would try to interview more variety of people to support my idea even more. For the future 8th graders I want them to be aware that the more interview you get, the better it’s going to be.

Catapult

The catapult project is a math project we are doing in Algebra 1 this year. We first build the catapult and then we used desmos to graph the arc of the catapult height vs time and height vs distance. By using the standard form we found the vertex and factored form.

Throughout the project, I have learned different things. I learned how to graph from just a video of the catapult and I have improved on turning forms into different forms and it also helped me to understand quadratic functions more.

There wasn’t really any challenges but for next time I think me and my partner need to make the catapult more stable, since every time the catapult shoots differently.

I think that the catapult project helped me a lot at understanding quadratic functions and I have learned a lot from this.

My polymer project is a polymer that helps children bumping into tables and causing unwanted injuries. To make this polymer the first polymer I and my partner thought about was gloop. Gloop is bouncy which will decrease the force. We started out with gloop, it’s bouncy and it will decrease the force but it’s not sticky enough.

Our second prototype is the same as the first but with extra glue. We measured 0.4cm more glue, this prototype was a complete fail, although it was sticky, the polymer was so watery it loses the trait that we wanted, the bounciness. So for the last trail, we added less glue and I can’t say it was really successful, it was a bit better but it was still watery.

None of the prototypes were really successful, but the last prototype was the closest to success. The process was hard and challenging, we faced many challenges because we do not know the amount of glue we needed to put in.

 

The Right to Choose

24 constants, 12 districts, 1 winner, the rest will not survive. People were forced to compete in this game. The Hunger Games is a dystopian novel wrote by Susan Collins, and I think one of the themes of this dystopian novel hunger games is ‘everyone should have the right to do what they want, the Government should not control people.’

 

The Hunger Games society is a dystopian society. Every year at the reaping season the election starts. Every district is forced to send 2 volunteers to a game. The game is not an ordinary game, only 1 person can make it out alive, the game was created because in the past the districted rebelled against the capitol, to remind all 12 district that this must never be repeated. “To make it humiliating as well as torturous, the Capitol requires us to treat The Hunger Games as a festivity, a sporting event putting every district against each other.” (Collins, 19) The rules are very cruel and the whole game is only for entertainment. “The rules of The Hunger Games are simple. In punishment for the uprising, each of the twelve districts must provide one girl and one boy, called tributes, to participate.” (18) The girl and boy can’t decide if they want to go or not, they are forced. Therefore, I think that everybody should have the right to do things and that the government(Capitol) should not control or force people to participate.

 

I was never thrown into a game that will decide if you die or not, but I read a short story and it really connects to the theme.

The short story is about the Childhood of Sun Yat Sen, he goes to a school that doesn’t have any freedom to think, they don’t have any right to ask questions, all they were told is that the teacher is always right they can’t have their own choices. This connects to the theme of the story, you can as well say that they were living in dystopian kind of world, and I thought about the school life I live now, we are encouraged to ask questions and encouraged to think differently.

 

People should not be forced to do things. Everyone should have the right to choose what they want to do.

We are making a polymer that can stick to surfaces and will have enough bounce to decrease the force.

 

The traits we want the polymer to have are: bounciness, stickiness, some stretchiness, and some rubbery properties.

 

First, we will try to create a mixture of these properties using the guide given to us on the different materials. We will try to improve our prototype by changing the amounts of individual materials we incorporate into our polymer until the time runs out or until we end up with something satisfactory.

 

We’ll test our prototypes by evaluating its stickiness (on surfaces), its ability to hold together, and its bounciness. We will do this by sticking it to surfaces and applying forces to it at various strengths. This way, we can test the practicality of our polymer.

Our goal for the polymer project is to design a polymer that can “round off” table and furniture edges, this will prevent small children injured if they crash into a table or furniture.

The target market audience for this product is for Parents with small kids and kids, this will reduce the injuries of their children and make it a safer environment.

Gloop has the characteristics we wanted for our polymer project, it’s not stuck, it’s super bouncy. These characteristics will ensure that children will not get hurt heavily since it will reduce the amount of force the children will feel.

Polymers are long chains of monomers; monomers are small chains of molecules. The process in which a monomer becomes a polymer is called polymerization. Polymers are repeated patterns of monomers. Synthetic polymers are man-made polymers that are made out of natural resources; some examples include plastics, clothing, and fuels.

The process of how natural resources go through a chemical reaction are usually heated then molded into the polymer. Rayon is made out wood pulp or cotton, in the beginning, Rayon is used for artificial silk it replaced silk due to the disease affect the silkworms in France, Rayon is mostly made for clothing, it’s is low cost, diversity, and comfort, this leads it to success.
