After eight weeks of Capstone research and rigorous studying, this video has been the fruit of my loins. This video is about the educational gap in China caused by the educational system in China. Overall, I’m pretty satisfied with my final project because I feel like I put in the effort to research and care about the topic at hand.

 

For the past couple of weeks, the whole Algebra 1 class has been designing their own catapults and graphing their catapult’s parabolas based on the prior knowledge about the quadratics. The purpose of this activity was to challenge students to apply their knowledge learned in class into a real-life situation. The class went through the design process and many, many times we made refinements to our catapult. In the end, to test our final product, we used our knowledge about the factored form, vertex form, and standard form to compete in a “catapult challenge.” Many of us in our class did not get the final result we wanted, however, my partner and I, in the end, were pretty satisfied with our own catapult’s performance—hitting around 40 % of our shots on target.

Here’s our catapult at work: Untitled 4

Personally, this project benefited me greatly both as a student of mathematics and as a person—due to the fact the activity itself, including the design process, is pretty challenging and thorough. I loved how engaging and thought-provoking this activity was, and it really put my knowledge of quadratics to the test learning about something in class is one thing, but doing something out of class and having to apply your previously learned knowledge is another. I felt like after the activity, my understanding of the different parts of a parabola and what each value means in the quadratic equation in both mathematics and physics definitely deepened because my partner and I were forced to plot the trajectory and make the parabola for how the ping pong ball was shot off the catapult and then change that same parabola from height vs time to height vs. distance.

The most challenging thing about this project for me was probably the design process. The design process was extremely important and how well the design process was completed affected how well a catapult could fire on the competition day. With the limited amount of time, it was pretty hard to fulfill all of our criteria and design a consistent and powerful catapult. We were forced to think hard and fast.

If I were to do this again, I would plan out my initial design more meticulously because then I would have more time to work on the parabolas and graphs. When I did this project, my partner and I spent too much time on the design itself, and not enough time on our actual parabolas. Just based on our stress levels before the competition, it is probably safe to assume that procrastinating on the parabolas was a bad thing—a bad thing that should not be recreated again.

 

PROTOTYPE 1

2 cm of glue

4 ml borax

50 ml liquid starch

10 ml water

10 ml pva

PROTOTYPE 2 (Final prototype)

40 ml white glue

9 ml borax

5 ml water

All in all, Prototype 2 is was most effective for meeting our goal, although I do believe that Prototype 1 is also a plausible and effective solution for people looking for a softer cushioning. But just in terms filling the criteria, Prototype 2 was better. I  believe that it was more successful because it was more resilient and kept its shape, and felt cooler. In all tests, Prototype 2 bested Prototype 1.  Prototype 2 was less slimy, more bouncy, and dropped slower.

Recommendations for Future Improvements to our Design: 

Both my partner and I believe that we should’ve found a middle ground between Prototype 1 and Prototype 2. Although Prototype 2 (Our final prototype) was able to keep its shape better and was less sticky than Prototype 2, it was not as soft and comfortable as Prototype 1 (shown on the bicycle seat). My partner and I wished that we had more time to test, so we could make the best product possible. A product that isn’t very sticky and able to hold its shape like Prototype 2, but still as soft and comfortable as Prototype 1. We also wished that we could find a better way to apply the polymer than just wrapping the polymer around the seat and placing a plastic bag over it (it would be better if we could make the polymer able to not stick to you even when you sit on it without a bag). I guess one thing we could do is wrap the cushioning over the seat and let it dry??

Prototype 1 is shown above

How to make our product:

Prototype 1:

2 cm of glue

4 ml borax

50 ml liquid starch

10 ml water

10 ml pva

Prototype 2:

40 ml white glue

9 ml borax

5 ml water

Simply pour all the substances into a cup and stir till everything mixes together. Then knead the polymer once it has a shape.

Final Reflection: 

For the past few weeks, Joy and I have been testing and testing to find the perfect polymer for the “Omni-Potent Cushioning.” This cushioning is primarily applied on seats, but can act as a heat insulating material, a cooling, and a shock absorber for your phone.  We tested our prototype and put ourselves in the shoes of people who face terrible bike seats on public bikes. Although our first Prototypes were not ideal, we continued to test and refine our polymer. Finally, after four classes or so of fastidious refinements,  we created a polymer that we were, overall, pretty satisfied with (we did find out that Prototype 1 was definitely more comfortable though, so we’ll be marketing both Prototype 1 and 2). All in I believe that my partner and I worked hard to create a product that can have a real world impact.

Our final video:

 

Describing Our Polymer

My partner Joy and I are making a polymer that can essentially do anything, but its main focus is to act as a cushion for public bicycles. We want our polymer to have the ability hold its shape, have a cool temperature, and have a soft surface.  After testing the base polymers: boogers, super slime, and gloop during science, we decided that we would make our final product soft like boogers, but be able to keep its shape like gloop.

PROTOTYPE ONE: 

 Prototype 1 PictureIMG_0056

2 cm of glue

4 ml borax

50 ml liquid starch

10 ml water

10 ml pva

1/2 a day of sunshine.

Goal: Successfully create a product that can hold its shape.

This was the first recipe that we came up with for our first prototype. It was inspired by the softness of the boogers and gloop’s ability to keep its shape.

Borax is used in this recipe so our product can keep its shape, and PVA is used for the slime to stick together. After some more testing, I realized that this product was almost ideal—it was soft, cool, and overall, comfortable to sit on. However, there were a few things that I didn’t really like about this first prototype. Number one being that it was a little too sticky. Number two is that it didn’t keep its shape as well as I wanted it to.

With these original measurements for our prototype number one, our product was still not as effective as we wanted it to be. We felt that if our product couldn’t even hold its shape and be less sticky, no consumer would want to use our product.  Therefore, we continued to test again and again—until we came up with the ideal combination.

Tests:

Bounce Test

Bounces 4 cm off the table.

Shape Test:

The slime dropped after about 40 seconds.

Stick Test:

This slime was sticky.

PROTOTYPE TWO

40 ml white glue

9 ml borax

5 ml water

With this recipe, we increased all measurements because we wanted more of the slime and removed pva out of the recipe to make the pad stiffer. This time, however, we put more borax in to see if this would make our product be less sticky and able to keep its shape—and indeed it did. Our second prototype basically fulfilled most of our requirements. It was comfy, kept its shape, and when stretched, would create an endothermic reaction. But after we made the second prototype, we realized that the first might be in fact more comfortable for some, so we kept them both—so consumers could have a diversified range of choices. We also proposed to place a bag over the slime, so stickiness wasn’t that big of a deal.

Tests:

Bounce test:

Bounces 5 centimeters off the table

Shape Test:

This slime was didn’t drop.

Stick Test:

The Slime didn’t stick at all

 

 

 

In order to deepen my understanding of the education system in China and my practice oral presentation, I presented a quick and concise elevator pitch to our class. I believe that I started out strong and emphatic and had good eye contact throughout my speech, but I know my ending was sloppy and weak. If I were to do this again I would’ve more thoroughly prepared for the pitch.

 

 

Our specific goal in this project:

The goal of our polymer project is to create a polymer that can serve as a cushion/ shock absorber for bicycle commuters.

Target Market Audience

Target Market Audience #1:

Our first target market audience are people who regularly commute on public bicycles.

How will this help them?

We’ve all ridden on an uncomfortable public bicycle seat before. After all, companies must maximize profit, and to do so, quality is often times damaged. What if I told you that you all your problems could go away with a blink of an eye. Our product, a soft and cool polymer , can reduce the impact and increase comfort of one’s daily bike ride by serving as a shocker absorber and cushion. Just simply place our product on your seat, and bam- you will immediately experience a spiritual  transcendence. Never again will your butt need experience the traumatizing experience of riding a public bike.

Using Observations of Base Polymers

We like how Super Slime is not very slimy and feels pretty cool. These characteristics are important because We primarily want our product to be used on the bicycle seat to reduce impact so we don’t want it to be feel very weird or slimy in its bag. The lowered temperature of Super Slime is great as well because  of  we want our product to be nice and cool for a more comfortable ride in the hot summer.

We like how the “Boogers” were soft and stretchy meaning that number one if our product is used on the bicycle seat it will be comfortable and not prone to break, and number two, if it is used as a shock absorber, it will work well.

 

We like how if we were to put something akin to Gloop in our final product in a bag, it would be durable and pretty soft.

 

Describing Our Polymer

 

We want our products Physical Properties to include:

• Cool

• Flexible

• Soft/Gel that doesn’t stick, not slimy

Synthetic VS. Natural

Nowadays, there are two types of polymers: synthetic and natural. Synthetic polymers are composed of many different chemicals, and are designed and refined by engineers and scientists. Examples of synthetic polymers include polyester, nylon, and epoxy. Natural polymers are found in nature. Some natural polymers include DNA, cellulose, and wool.

What is a polymer?

A polymer, in it’s most basic definition, is a useful chemical made of repeating chains of molecules. To make these chains of molecules and polymers, many links or “-mers” must be chemically bonded and polymerized. Polymers are found everywhere in our world and everywhere around us. They have and still are making life easier.

Synthetic Polymer #1

Polyester

What natural resources does this come from?

Polyester comes from petrochemicals and is formed by mixing ethylene glycol and terephthalic acid

What do we use this synthetic material for?

It is found mostly in the clothing and apparel industry.

Synthetic Polymer #2

Nylon

What natural resources does this come from

Nylon comes from petrochemicals as well and is formed by mixing adipic acid and hexamethylene diamine.

Chemical Reactions

How do natural resources go through a chemical reaction to become synthetic materials?

*important words to think about…polymerization, monomer, polymer

 

Natural resources like petrochemicals go through polymerization to bond together and form a polymer. Such an example of polymerization can be found in how polyethylene is created. Polyethylene is as simple as it sounds- meaning that it is made out of many ethylene molecules. Ethylene can easily bond on both sides, so when ethylene goes through polymerization it can for Polyethylene.

What is a monomer?

A monomer is a molecule that theoretically can be bond easily on both sides and can go through polymerization to form a polymer

What is polymerization?

Polymerization is the act of forming a polymer by creating chains of monomers.

The Chinese Cultural Revolution was one of the bloodiest, devastating, and heavily-impacting events in recent history for China, yet, it is also one of the least talked-about and most sophisticated revolution as well. It completely revamped and reshaped Chinese culture, core ideas, and beliefs. To this day, the profound impact of the Chinese Cultural Revolution can be seen everywhere: throughout not only the government and their governing principles but also in the lives of the everyday people.

After slaving through resources and meticulously choosing my every word, this, my journal is my final product. I am extremely satisfied with it, and I hope I can provide more insight to all of you about the Cultural Revolution through my portrayal of a run-of-the-mill student in my Journal who changes immensely over the span of the revolution.

The L21s

What are the L21s? 

L21 Skill: Global Mindedness

 

Claim: I have grown to become more aware of people’s lives around of me, helping me become a more global-minded individual through the Out of the Blocks Project

Evidence:

Out of the Blocks Beijing

Journals

 

Reasoning:

Although I have lived in Beijing for a while now, and although I do consider myself as an international citizen, I feel like I have always been stuck in a sort of bubble. A bubble of prosperity, a bubble of “Canadianess.” But this year, due to many projects focused on the sole purpose of getting me to put myself in other people shoes, I have become a much more global-minded person. Through these projects, I’ve come to understand that for peaceful and harmonious communication to occur, one must delve deep into the depths of other people’s lives—come to understand the other person’s motives, their hardships, and the beautiful things about them.

L21 Skill: Communication and Collaboration

Claim:  I have progressed as a communicator and a teammate throughout the year through various projects and tasks like the Common Craft Video and Socratic seminars.

Evidence:

http://blogs.isb.bj.edu.cn/21harryc/2017/10/18/the-coming-of-age-the-outsiders/

http://blogs.isb.bj.edu.cn/21harryc/2018/03/06/into-the-wild/

http://blogs.isb.bj.edu.cn/21harryc/2017/10/13/in-the-midst-of-the-lonely-night-sonnet/

http://blogs.isb.bj.edu.cn/21harryc/2017/09/20/the-handmaids-tale-exposition-analysis/

Reasoning:

Although I’ve always been fairly good at communicating through my writing, I’ve never really been great at verbal communication and being a good teammate in class. This year, because of many different projects that required me to not only work with someone but work with someone I’m unfamiliar, and maybe even guide them in a discussion, I have progressed as a Communicator and Collaborator.

L21 Skill: Innovation and Creativity

Claim: I have become a better artist not only in the way I draw but in the way I think

Evidence

Artist Statement (Autosaved)

Reasoning:

I never really considered myself an artsy or creative person. But now, I realize the only thing that stopped me from becoming “artist-like” before, was that I couldn’t think like an artist. This year, because I was forced to stop and use the artist habits, I do believe I have become a better artist.

L21 Skill: Responsibility & Leadership

Claim: Through participating STUCO, I have become a better leader.

Evidence:

Chartwells Report (2)

Announcement

Reasoning:

I never really took up leadership before at school. Therefore, I never really had a sense of responsibility before. I would always goof around. I would always disrespect my teachers and not listen to them. But this year, after I took up some leadership, I definitely feel like I have become a more responsible person.

 

Some work I’m proud of:

每个人都想要幸福,没有人想要痛苦,但是如果没有一点雨,哪儿会有彩虹呀

 

After slaving through various resources, battling through the night, meticulously choosing our every word, and NOT exaggerating our blog posts to make ourselves sound smarter, my partner and I put our heads to together and somehow managed to come through this battle intact—completing our Chinese Cultural Revolution common craft video. In our video, we explain key turning points in the massacre and power struggle that was the Chinese Revolution and give historical analysis on the central characters and events. Amanda and I are both very proud of our work, and we hope you enjoy!

The video was produced on iMovie and filmed with iPads. It required extensive inquiry and research as well as communication, collaboration, and technological skills in order to make this video. This is because everyone had to do fulfill their own roles— whether it was in making the video, writing the script, or finding the graphics. All members of our group also had to think like a historian. We all had to inquire, analyze, and think about change and continuity. One of the hardest things about the project was that we had to find the perfect balance between a boring, and a fun video. We had to be educational, concise, and entertaining at the same time. Overall, I am satisfied with our final product.
