Breaking the Barriers (Capstone Video Project)

With 2 months of hard work and research, my finalised Capstone Video was done. Several SDG goals were there and my topic was SDG 16 related global governance. Although it was a hard topic, I still managed to research sophisticated websites through primary, secondary, and various sources.

Experiencing Graph and Equations with Visualisation of Catapults

Preparing the Challenge

At the start, my group searched for a lot of ideas to fix and make catapults. We considered about sustainability, accuracy, and several other techniques a catapult needs to get a successful product. In the end, we planned out just a simple catapult to build in the Phet Lab during Math Class.

Making the Catapult

During the process of building the catapult, there was a lot of problems. Our visualisation of the catapult wasn’t nearly to our plan and we felt like we wasted our time during the first session of building. That was the point where we changed our minds and decisions to construct a new source which was a crossbow. A crossbow as a whole is very hard to make and takes a substantial amount of time. Although it took several hours to build and finalise the whole product as a whole, we were able to manage and make the catapult at the end.

Testing the Catapult

During the catapult challenge, I felt like the crossbow was okay and was on average. When the size of the ending point was shrinking to a smaller size, it was getting harder and harder to make the accuracy percentage to a higher level.

Reflection

Going through variety of perspectives, acknowledging diverse lenses, our final catapult was successful. We tried to use a much solutions and ways to solve out different challenges and I got to know a whole lot about quadratic equations and graphs.

Polymer Project Journal Entry Notes 4

Design Journal Checklist # 4

 

Optimising Prototypes

  • You describe important observations about each of your prototypes and identify strengths and limitations of each prototype.
  • Recommendations for future improvements to your design.
  • You make a claim about which prototype was most effective for meeting your goal, and your claim is supported by evidence from your observations.
  • You present a clear method for how to make your final design.
  • You reflect on the design process and what you have learned.

Communication

  • Your writing is clear and concise with few grammar errors
  • You use scientific terminology
  • You create multimedia that suits the post and presented my information in a way that clearly explained my topic.
  • Group video is also linked to post
  • Your blog post demonstrated a sound ability to meet the publishing standards for a blog post, including a clear title with “Polymer Journal #”, a category of “Science,” and tags

 

Prototype Observations

Prototype Observations Strengths for this Prototype Limitations for this Prototype
-Color is light blue

-Not too sticky

-Bouncy

-Easily rips when pulled on each side

-Easily breakable/fragile

The bounciness and the stickiness was very close to what we needed it to be. Wearable products need these techniques. It was to weak for it to be a strong and tight wearable product. It easily ripped off which wasn’t good to use.
-Color is light green

-Very sticky

-Not bouncy

-Stretchability is excellent

-Not easily ripped off

The stretchability and the tightness of the polymer was very effective. There was less inconvenience with putting it on a shoe (easily attatch to stuff). It was too sticky, so it caused the feet to get stuck in the shoe during the experiment. Useless when it is hard to take something on and off.
-Color is pink

-Not too sticky

-Stretchability is just right

-Not easily ripped off

-Bouncy

-Soft

The criteria was all met and it added all the benficial points of the first two prototypes which meant that this was the best design. It had to have a little more stretchability, but it was full enough to have a complete wearabel product’s ability.

 

 

Prototype Claim

Use evidence from above observations to complete.

 

Prototype # 3, called Loopie, was most effective for meeting our goal because:

Our goal was to create a polymer that is not too sticky, stretchability is long/wide, not easily ripped, bouncy, and soft for a wearable product. As we can see in the picture above (pink), it has the perfect ability and technique. All the expectations were accomplished. In order to have a wearable product be convenient, it needs to have a just right stickiness and soft texture, so that it doesn’t cause any other catastrophic problems. For mainly shoes, it can be very effective. With various sizes using our hands to stretch it for larger use, it can be beneficial for kids who are growing. On the other hand, glasses can be fixed (shown in the video).

 

 

 

Method of Final Design

Give a summary of how your final product will be made.

Make sure you list the steps and amounts used.

 

  1. Start by having PVA solution, borax, water, white glue, plastic cup, stirring rod, and graduated cylinder.
  2. Pour 51 ml of PVA solution using the graduated cylinder into an empty plastic cup.
  3. Pour 0.5 ml of water and white glue using the graduated cylinder into the plastic cup.
  4. Pour 10 ml of borax using the graduated cylinder into the plastic cup.
  5. Stir the substances inside the plastic cup using the stirring rod.
  6. Put the substance changed to a polymer on your hands and gently smooth it out.

 

 

Reflection

What was the process like?  What was challenging?  What was interesting?  What did I learn?

I felt like that in order to create a perfect polymer, it is very challenging. At first, I thought the we just needed to combine the materials given and mix it to create and meet our expectations. However, that wasn’t easy, because the accuracy and the specific amount of materials change and makes the whole process to fail. I found out that white glue wasn’t the main one that made the polymer sticky, it was when white glue was mixed with borax the most stickiest part. Originally I thought white glue itself was very sticky. I learned that in order to create a polymer, we need to understand process of polymerization and if we slowly see the process, the connection between the polymer and the actual experiment is very fascinating to do.

Elevator Pitches

This is an elevator pitch about global governance in the Capstone Project. The goal for our project was to practice oral presentations and clarify our own thinkings for the main topic of SDG goals. With long time of practicing, the elevator pitch was full of our own ideas.

Some things that I did well is a clear, loud, expressive voice and used various vocabulary describing global governance.

Some things that I need to improve on is to try to make more eye contact and details on what things go on in global governance.

Polymer Project Journal Entry Notes 3

Describing our polymer:

1. We are making…

A polymer named Loopie that can be used to fix and make wearable products such as shoes, glasses, clothes, etc.

2. We want PHYSICAL PROPERTIES to include:

  • Not sticky (if too sticky, it is vulnerable and uncomfortable for people to use)
  • Stretchability (both long and wide, so that if there are different sizes for children, people can easily pull and shrink)
  • Bouncy/Soft (very convenient in walking, so that it doesn’t feel like walking on a hard surface, similar to shoe company design techniques and abilities)
  • Waterproof (people won’t experience any type of inconvenience on taking on and off wearable products)

Our plan to develop our prototype:

1. First, we will gather materials that we need in order to make the perfect Loopie(polymer). There is PVA solution (50 ml), Borax (5 ml), White Glue (0.5 ml), and Water (1 ml).

2. Second, we will mix and swirl up all the materials from step 1 and make it into a Loopie. If there are problems with the design, such as not having the exact physical properties, we will need to consider and redo the materials again. 

3. Third, we will test out the Loopie to check if it meets the physical properties criteria. One of our main benefit of the polymer is the waterproof ability. If we do the experiment shown in our main video and it works completely like that, that will be okay. 

4. Finally, we will attach the design to an actual wearable product to test out the benefits and rooms to improve furthermore. 

Method and Results:

First, in order to prove that these ideas and physical properties work is using several experiments to prove that the polymer is working. For example, during the video, there is an experiment that shows the waterproof ability and technique by putting in paper and comparing it to a hand towel. Moreover, the polymer can go long and wide by stretching it out which is easy to prove. Then, we are able to show the bouncy characteristic by bouncing it on a flat surface. By this, the physical properties can be proven which can be very effective.

Polymer Project Journal Entry Notes 2

Goal for our polymer project is to create a wearable product using polymers. 

Target Market Audience

Some Examples:

Adults

Parents with small kids

Elderly

Kids

Teens

Boys/Girls

Teachers/Businessmen/Shop Owners

Pet Owners

Travelers

Target Market Audience How will this help them?
Target Market Audience #1: Athletes/Sports that use shoes and gets easily damaged. The polymer design is not sticky and is stretchable/feasible for people to use when they have damaged products such as shoes.
Possible Target Market Audience #2:

*just in case you have more than one target market audience

Little kids that often likes to go outside. The polymer design can fix several parts of the shoe that makes little kids get more free and go outside very often.

 

Describing Our Polymer: 

We want the physical properties to include:

-Stretchability (can stretch wide and long, can shrink short and narrow)

-Not adhesive and sticky (if too sticky, the consequence will be hard to wear and not feasible)

-Smooth (shouldn’t damage one’s part)

-Soft/Tender surface (more comfortable when worn)

Polymer Characteristics We Are Looking For

*Gloop, Super Slime, Stretch-tastic Slime, Oobleck

Polymer Characteristics Why this is important
Gloop -Stretchability (can easily stretch and return to its normal position afterwards)

-Sticky (sticks to a certain object when touched)

This is important, because as a goal and a wearable shoe product, it needs to have a characteristic of stretchability. Its ability to stretch and return to its normal position is very effective.
Super Slime -Stretchability (easily destroyed and broken into two parts when stretched)

-Not sticky (it can feel like its sticky but does not stick on a certain object when touched)

This is important because when its not sticky, it is very useful for the feasability and the preferability for people can be substantially high.
Oobleck -Stretchability (too easily stretched and broken down)

-A little sticky (it sticks and breaks off afterwards)

This is important, because although it doesn’t match the product and the physical properties, it shows a proof and evidence of what kind of sources cannot fit into the object.

 

Developing our plan: 

First, we will try to gather as many polymer experiments that can be helpful for our product that we are trying to sell. For example, there are several ingredients such as PVA solution, Glue, Borax, etc. With these materials with quantitative and qualitative datas, we are going to try to mix various things together to create the best design.

Second, we will need to gather data and try to sort out the main characteristics of each design and prototypes that we made. This way, we can figure out what sources are useful and what not.

Third, we will try to make the best design selected, and make it into various sizes that can fit into various things. The topic is to create a design that is wearable which means that there needs to be several of the final designs to make the polymers fit in the wearable products.

Finally, we will take pictures of our process and make several videos to put it all together into one to tell our final products. We will try to identify the techniques that make a selling video more interesting and persuasive to buy.

Polymer Project Journal Entry Notes 1

Synthetic vs Natural 

Synthetic Materials: a man-made macromolecule that has thousands of repeating units. (Examples: Bottles, Super Glue)

Natural Materials: happens in nature and can be extracted, often water based. (Examples: Silk, Wool, DNA, Rubber)

 

Polymers and Where They Come From

Polymer: comes from a greek word meaning ‘many parts’ and it is when numerous monomers come together.

Synthetic Polymer #1: Bottles

Natural Resource of Bottles-High Density Polyethylene, Polyvinylchloride

Use of this material-Feasible to carry products more easily with bottles

Synthetic Polymer #2: Super Glue

Natural Resource of Bottles-Epoxy, Hydrocarbon

Use of this material-Creating the ability to attach two or more different things easily

 

Chemical Reactions

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

First, in order to become a polymer, there needs to be a process where large numbers of monomers combine to form polymers. This is called polymerization. If we consider natural resources as monomers and they are combined to form a chemical reaction into a polymer, that will be a synthetic material. As we know, synthetic material are man-made macromolecules, which means that large number of monomers that are completely natural, goes through people’s hands and results to a synthetic material that people use in their daily lives.

What is monomer?

Monomers are combined to form a polymer. Hundreds and thousands of monomers add up together to form a long chain to become a polymer. It is a molecule that bonds with other identical molecules.

What is polymerization?

Polymerization is the process where large numbers of monomers combine to form polymers. It is basically the process of monomers bonding together and forming a polymer. This stage and action is called polymerization.

Revolutionary Voices Journal

Going through various resources, learning from different perspectives, I have completed my revolutionary journal that is all about the American Revolution. Although it is about a young boy who went through the American Revolution, various point of views were applied from the British and the American ways. I chose this revolution, because it showed the process of how one of the most powerful countries gained Independence and their own government. By this, I learned that during a revolution, a one small spark can cause a catastrophic effect later on.

American Revolution in Simple English

After weeks of research, days of hard work, Chris and I have created a final common craft video about the American Revolution. During this process, I had the opportunity to solve my curiosity of major events. For example, the Boston Tea Party, Boston Massacre, and other happenings. Many other revolutions such as the French, Chinese, and Syrian revolutions were interesting, but learning the American revolution very specifically was very exciting. In the research process, there were examples and explanations that were very sophisticated in the resource pages. We used Thoughtco website, textbooks, and other reliable tools for this particular project.

Nonfiction Blog Post: Outbreak

The book Outbreak by Bryn Barnard clearly depicts the theme about how a disease won’t just one person’s life but can change the world. The author uses several types of disease as examples to explain.

First, the author described the Black Death as the first disease. ‘The Black Death probably started in 1331 in Central Asia, carried there by infected Mongol troops returning from Burma. By 1346, having killed millions and traveled with armies and traders along the Silk Road, the epidemic arrived on the Black Sea’s crimean Peninsula.’ (6) shows how serious and how big the effect was on a very large scale. ‘Finally, in the world of the nobility, the social, economic, and political crises caused by the Black Death were blows from which the ruling classes never fully recovered.’ (4) later on showed that the one disease made not only one, but 75 to 200 million people suffered and died. As this clearly showed, a certain disease cannot effect and take one person’s life, but instead can cause catastrophic disasters that no one can ever imagine. The author explained the seriousness and the severe consequences that one can face that sounds like it can harm one human as a whole. However, since the author moreover talks about the effect to a wider degree, the theme is diseases can change the whole world.

Second, the author delineated the Yellow Fever as the second disease. ‘The Flaviviridae virus was very the major cause of the yellow fever that started off weak, but if not cured, it spreads fast and will eventually be able kill a whole person.’ (18) shows how deadly the virus was and how many people did not cure and died after all. ‘The yellow fever was carried on to South America, more parts of Africa, and in North America. It was widely spread causing extreme death population that made the countries unstable. When the African ships sent goods and resources to the Western world, there were several slaves that had yellow fever that caused a spread almost world wide.’ (16) showed the result of large amount of people dying and suffer from just one section of an African region had the disease. These major outbreaks not only shows the effect of a deadly disease, but at the same time, it shows the spread and enormous effects towards many people. This once again exactly fits correctly for the theme of having effect shown to several people in the world.

To conclude, the author described how diseases not only can be deadly and serious to one human being, but can also influence the world as a whole affecting numerous in various causes.
