Capstone Video – Climate Change Through Education

During the capstone project, after weeks of research. I created a video focusing on the importance of solving climate change and the importance of including it in education. For the video, I did well on including all needed information and data in two minutes. And the font and style presented visually were the same for the whole video and supported every frame with appropriate pictures. A wish for my self is that next time creating a similar video, I hope I can use more data supporting the reasoning.


Capstone video – climate change through education:


Catapult project reflection

In this module, we are learning about quadratic equations and parabolas. The catapult project will allow us to further extend our selves and better understand quadratics. We will interpret quadratic functions in real life situations. For the catapult project, we first designed and created a catapult that we think will be successful in both distancing and accuracy. Then, we had to record it when it fires. We interpret the quadratic function by inserting the video we took into logger pro. The function is based on the curve that fits best in the points the ping pong ball passes over time. The values for given will be used in our function for different coefficients. Then changing the standard form function in the other two forms (vertex form, and factored form) that shows different information for the situation. By the end of the catapult project, we had the catapult challenge, where we had three mini-challenges that we have to try and go through. It includes hitting targets with different sizes from a distance, hitting a target from a height, hitting a target that’s leveled, and the mystery challenge where we had to hit and land the ping pong ball in the trophy from a distance. Those activities will not only analysis of the function, but also, we had to estimate the power we had to use based on the function.


Catapult when fired:


During the catapult project, the most important knowledge or point I learned was the analysis part of the video. Before the project, I knew that we can draw a quadratic function based on its value and equations. But in this project, I learned how to analyze parabolas in real life situations in logger pro. However, there is also challenging aspects of this project. The most challenging aspect of the project to me is the catapult challenge because we had to use our function and estimate/calculate the distance or power we need to use in order to hit the target. Personally, it is hard to perfectly make sure that the trial worked properly just like the calculation we did. This project helped me in the learning of quadratics. Before the project, I didn’t know much about what the different values stand for in the function. However, after the catapult project, I could fully explain how and why each value could make a difference in the function’s parabola. If I could do this project again, I think I would change the design. I would create a catapult that has measurements of some sort. So, every time I fire the ping pong ball, I can record down how much power did I use pulling it and how far it went. Therefore, next time I can adjust the power based on the previous trial. Overall, the project was very successful and useful.







Elevator Pitch

This is an elevator pitch I did in the humanities class. I focused on the importance of education for climate change and explained various reasons. Because climate change is one of the most important issues people will have to solve in the future, therefore I chose it as my topic for capstone project and elevator pitch.

I did good in the fluency in the presentation. However, I was too nervous during the presentation and kept looking at my note card even though I remembered my script. Also, I spoke too quickly. For next time, I would have to make eye contact with the audiences and slow down my pace for the elevator pitch.

Polymer Project – Journal 4

The physical properties that we wanted to achieve was moldable, sticky enough to stay on an object, and has to be comfortable when holding on to it. At the beginning of the project, we decided to take trials combining the few kinds of polymers we experimented in class. Booger + Gloop and Booger + Super Slime were the ones we created because Super Slime + Gloop wouldn’t hold on to things good enough because both Super Slime and Gloop’s physical property shows that they aren’t sticky enough compared to booger. In our experiments, Booger and Super Slime did not work well. First of all, it is hard to mix Booger and Super Slime together because of their completely different physical properties. However, after it gets mixed together, it could still be broken easily because of the physical properties of Super Slime. The good thing about mixing Super Slime is that for our prototype, Booger + Super Slime had the best texture. But after it dried out, the two prototypes had similar textures. For Booger + Gloop, the physical property was closer to what we wanted. Even though it wasn’t perfect, but we were on the right track. For this prototype, it had the ability to stick, the texture, in the beginning, wasn’t as good as the one with Super Slime, but after it dried, they were similar. Most importantly, this prototype could mold better. After forming it into a shape, it stays in its shape when dried rather than just collapsing. Next, we experimented and adjusted this prototype (Gloop + Booger) into a better working product. There were still a few problems with our prototype. So we adjusted it based on what physical properties we needed and finally we got our final product.

Polymer Project – Journal 3

Our goal was to make a polymer that forms into a grip for a cup-like structure so that it’s easier for people who need help in holding things. The physical properties we needed was that it has to be moldable, and it has to be able to stick to items but easy to remove. Also, the texture of the polymer should make the customer comfortable holding on to. During the process, we created a family tree by combining different polymers we experimented in class. Those polymers included Gloop, Booger, and Super Slime, which is the top level of the family tree. The middle level included 2 kinds of polymer: Booger+Super Slime and Gloop+Booger. The ratio added for both polymers were 1:1. Later, we combined the two into a final product which is the lowest family tree. In the beginning, Gloop and Booger worked better. Compared to all, because it sticks the best. One method I decided to use is to check the polymers in the different time period. Becuase it will work differently when it dries compared to when it was just created. Therefore, we checked them after 20 hours, the three had slightly different texture but all dried out, Gloop and Booger also felt the best, it was soft and comfortable but wouldn’t break easily. However, we felt that it still had to be a bit stickier in order to stay on the cup-like structure, therefore we adjusted it and changed the ratio. For the second-class period, we added Gloop and Booger together with the ratio of 1:1.5, it appeared to be more successful and met all the physical properties we wanted. It sticks easily, it was moldable, and after it dries it felt comfortable. Therefore, we decided to use it as our final product.

Polymer Journal #2

Our project’s specific goal was to be able to create a grip or handle of something. We chose to make a grip for a water bottle, or cup-like structure. Because many people in our world do not have the ability or strength to hold I cup without dropping it. Most of those people are elderlies. Our goal is to make the grip fit their hand while also making sure that it’s more comfortable holding on to so they won’t drop it easily. I am sure this polymer would be very useful in daily life for them. During the process of discovering the polymer, I would have to first try mixing polymers that seem to create good results together. Then, take the better trials and adjust the amount of each kind of polymer added. For example, I would leave the polymer on a flat surface and after a day check how it appears now in its current form. Then go to the last step – use it in real life situation, test if it works.

In order to reach the goal, we need to reach specific physical properties that the polymer will need:

Soft: Comfortable when holding on to.

Flexible: Fits people who use it.

Moldable: Adjust the handle – Helps on the flexibility.

There are three kinds of polymers we explored during the past lessons:

Gloop, Booger, and Super Slime

Gloop: Sticky in the beginning, molds after a while, bounces slightly.

Booger: Extremely sticky, very stretchy (breaks if pulled quickly), doesn’t bounce.

Super slime: Not sticky, breaks easily, air inside, half transparent, stretches a slowly pull.

In the next few class periods, we decided to mix the polymers with different properties and check how they work together as a whole.



Polymer Journal #1

In this polymer project, we started learning about properties that they have. I did research on different types of polymers, different terms, and vocabulary. The goal of the project is to create a polymer that has its own use in the society. So, what are polymers? A polymer is a chemical compound, where chemicals bond together in long repeating terms. Polymers often have unique properties used in many different ways. There are two kinds of polymers: natural and synthetic. Synthetic polymers are the polymers that are human-made using polymerization. Alternatively, natural polymers exist in the world naturally. Every polymer has unique properties, and many of the polymers are helpful in our daily life. Human-made polymer uses the method of polymerization. It is used to combine monomers together using the covalent bond to get synthetic polymers. Created polymers are synthetic polymers. In the process, monomers are the most important part. It is a term used for the things that bonds together in order to form synthetic polymers. It is used in polymerization. Examples of products that are human-made are plastic, silicone, fibers, and rubber. Some natural polymers could be rubber, amber, wool, and silk. As we can see, some materials like rubber could be both synthetic and natural depending on how it was created. Polymers are really useful, for example, plastic is used to carry things. Seal things, or keep things warm. Rubber could be both synthetic and natural polymer. It is very useful in protecting an item while carrying it. Overall, polymers are useful resources we could use in daily life.

Revolutionary Voices Journal – AR

This a revolutionary voice journal, it narrates the major turning points throughout American Revolution with the perspective of the colonists. The three turning points include the Stamp Act, the Boston Tea Party, and the Treaty of Paris. Before the journal entry, we did weeks of research on the American Revolution identifying major turning points and cause and effect. Throughout this journal entry based on primary resources, I learned how colonists felt during the revolution and dug deep into the internal conflict. Hope you enjoy the journal.

American Revolution in Simple English

If you are interested in American Revolution and was looking for a video, this might be helpful. Over the past few weeks, we researched and learned about the American Revolution. We researched from reliable sources including Thoughtco website, textbooks, and many other sources. We identified turning points, cause and effect, and different aspects including the colonist’s perspective, and British perspective about this event. Then we created a common craft video explaining the major turning points during the American Revolution and how it shaped the final result of the resolution. We hope you enjoy the video.



Nonfiction Blog Task – The Double Helix

Nonfiction Blog – The Double Helix


Many things we use nowadays were once undiscovered, electronic devices, transportation, and buildings, these were all new discovery. One of the most important aspects of discovery is knowledge, which includes science. In the book The Double Helix, it narrates in a personal aspect from James D. Watson of the discovery of DNA. Starting from the entrance to Cambridge University, then to work with Crick, then to finding DNA structure. It showed the theme of new discovery never comes without hard working and multiple attempts including failures. Another theme is that in the nineteen hundreds, women scientists did not get recognized by people, and were often limited to things that were easy and simple.


During the process, there were many steps that led to the discovery of DNA, it includes gathering basic data, creating a hypothesis, analyzing them, and finally, there is the result. From our knowledge today we know that DNA is a double helix structure (DNA: more info.), but back then, they didn’t know anything about DNA, during the step of hypothesis with the help of Rosalind, they thought the DNA structure was a three-sided helix. But with the collaboration and teamwork with Crick, eventually, they had found out how DNA is structured and how it works. While being proved correct. They worked collaboratively and fixing minor mistakes over and over again. It is hard to find out something that you don’t know, therefore, multiple attempts were taken over and over again to reach the actual structure. “Our spirits slowly went up, for it Pauling had found a really exciting answer the secret could not be kept long.” To Watson and Crick, or maybe more scientist in the same area, Pauling was a really strong competitor, because of an A – helical structure that he published. Pauling was the motive that made Crick and Watson work harder with more efficiency. The time they published their results, they were still afraid that something was wrong.


The other theme is about Rosalind Franklin, she was an extremely intelligent scientist, in Watson’s account during the discovery, much helpful information had been collected from Rosaland’s report. Also, she helped Watson in the discovery of DNA. But she wanted to do her research on actual biology topics, but Maurice had been negative about that, “slowly and precisely he detailed how, in spite of much elaborate crystallographic analysis, little real progress had been made by Rosy since the day she arrived at Kings.” Complaining how she did not do the tasks that Maurice wanted her to focus on. Also, later when this book Double Helix was published, people did not recognize her work in discovering DNA just because of the thought that women should not be doing lab and science. (More about her)


Even though The Double Helix was a book written in a personal account, but it still showed clear themes that caused them in the success of discovering DNA. It was the hard working and collaboration skills that pursued there goal.
