I made an infographic explaining the physics behind a magnetic levitation train, the pros and cons of installing a maglev train, and how Vietnam could benefit from installing the vehicle.

This was important to me because I enjoy making infographics, and this topic was particularly interesting to me as it was something that I have never thought would have a possibility to be mainstream. It made me think a lot about sustainable transportations, and what we can do right now to make our future more sustainable.

My main findings from the project was mostly physics-related components of this topic, because I had some background knowledge about maglev already, and specific pros and cons of installing maglev trains that have a potential to completely change the environment of a region.

My main challenges in my project was technological. I struggled a lot trying to create the infographic (fun, but still painful) because I kept accidentally deleting some of the parts that I wanted to keep. I also had some issues with time management, as I underestimated the depth of this topic and set myself too limited time for research.

I believe my strengths lie in paragraph writing and organising information. My weaknesses would be lack in self control and ability to find good visuals.

This is my final product: https://create.piktochart.com/output/30493950-new-piktochart

Over the past few days of working on research for this project, I have learnt a lot about magnetic levitation trains.

Magnetic Levitation Trains are 'floating' vehicles for land transportation that is supported by electromagnetic attraction and repulsion.

I discovered that maglev trains were first conceptualised in the 1900s by an American professor and a French engineer, Robert Goddard and Emile Bachelet.

 

I also found out that maglev trains utilise materials below for levitation and propulsion:

  • superconducting materials
  • electromagnets (hence the name)
  • diamagnets
  • rare-earth magnets

 

I was introduced to two types of maglev trains;

  1. electromagnetic suspension (EMS)
  2. electrodynamic suspension (EDS)

and the differences between these two types;

where EMS uses attractive forces between magnets on the train and and magnets on the guide way, and on the other hand, EDS uses repelling forces between magnets on the train and magnets on the guideway.

 

I have learnt the benefits of maglev trains, which are:

  • economic
    • longer lifespan
      (fewer materials need to be replaced due to the absence of rolling friction)
  • social
    • speed
      (maglev trains eliminates rolling friction, thus can reach higher speeds than conventional trains)
    • safety
      (the chances of derailment are lower than conventional trains)
    • interior space options, comfortability
      (design of maglev trains can be built wider than conventional trains, which means there are more options for how to utilise the interior space.)
  • environmental
    • reduces air pollution
      (no fuel is burnt, results in little to no air pollution)
    • reduces noise pollution
      (produces less noise than conventional trains due to the absence of rolling friction)
    • less damage to landscapes
      (do not need to excavate tunnels or manipulate landscapes to accomodate train tracks because maglev trains can work operate on higher ascending grades of up to 10 percent)

I have also learnt the disadvantages, which are:

  • economic
    • expensive cost of construction
      (rare-earth elements are expensive to recover and refine)

 

I have completed most of my research and I am ready to move onto the second step of making the infographic.

One of the main things that have been challenging for me was time management. I have been struggling to meet the deadlines that I have set for myself, because I underestimated the amount of research I had to do. So I had to change my timeline a bit, so that I had more time to do the research, only to a point where I still had time to thoroughly edit.

 

This is my timeline and I have highlighted the things I have completed. 

 

I have tried to set my timeline in a way where there is equal work distributed over each day, so that I am not cramming everything in one day. I have also scheduled my timeline so that I have almost everything done by 17th of March, which gives me time to ask my peers to give me some feedback.

Overall, I think my project has been going well, except for the fact that I had to reschedule my timeline, but other than that, I have been able to learn a lot about maglev trains and how they work.

I am a huge fan of reading books. But I don't read a lot of books. In fact, I have probably read less books than most of you reading this post right now. I just spend a lot of time reading my favourite books, often the same ones over and over again. I collect these books and I still take them out from my shelf every so often and dive into the story world that I have visited numerous times before. The thing that I have realised when living in a few non-English countries is that the "English" bookstores very often do not stock the books that I desperately need. I am not talking about the extremely mainstream ones, like 'The Hunger Games' and 'Divergent,' although I have seen some "English" bookstores that did not stock those books. I am talking about the ones that aren't that popular, but are still well-known amongst many readers around the world. This is something that I would like to change.

Although this motivation of change initially came from the inconvenience I very so often experienced when trying to find an English book I want overseas, I have decided to discuss other benefits that could come with installing a maglev train in Vietnam. So for this project I have decided to make a 'proposal' to the Vietnamese government explaining why installing maglev trains in Vietnam will be beneficial. This 'proposal' will be put into an infographic format, with several paragraphs and diagrams explaining the physics and the reasoning behind installing maglev trains in Vietnam.

 

My research question is:

To what extent will Magnetic Levitation Trains be beneficial to the economy of Vietnam?

And my sub questions are:

  • What are the physics behind a maglev train and what makes it possible to travel so fast?
  • When were maglev trains first invented?
  • How many countries currently use maglev trains?
  • Are there any geographic factors to consider when installing maglev trains?
  • What are the benefits of installing maglev trains?
  • What are the drawbacks of installing maglev trains?

 

My timeline for completion is: 

Experiment: How to make a paper plane that travels as far as possible

By Dong, Jason, Linda, Trinh, Hye Yeong

We have decided on using the third design, based on the experiments from last class. We tried to manipulate the wingspan for this design, by folding the airplane using the same method but changing the location of the fold crease of the wings. We then flew the planes 3 times each to measure the flying distance.

As you can see, because we selected our best design for our final product, our independent variable for this experiment was the wingspan (m), so we have prepared 3 models with different wingspans, but with the same design.

During our experiment, we have figured out that for this design, the larger the wingspan, the less distance it flies due to the additional weight.

The graph based on the data that we collected proves our hypothesis about this design.

In this experiment, we have figured out the best size for this design, and further proved the inverse relationship between the wingspan and this particular design.

I made a poster about how climate change impacts the coffee industry, with some visuals and explanations. I chose this topic because ever since I was in year 4, I always woke up early in the morning and made coffee for my parents. Brewing coffee had become a part of my daily routine, so I thought this project would be a great opportunity to learn more about how climate change impacts something that was so integrated into my life.

My main findings from the project was that Brazil and Vietnam are the world’s largest coffee producers, and that many developing countries heavily rely on commodity export, which is not really sustainable. I also learnt that there are many factors that affect the sustainability of an industry - the economic, social, and environmental factors, which are all connected to one another. Working on this project also made me realize that the impacts of climate change are indeed vivid and real, and that the current generation must work on halting global warming, not just for the future generations, but to live in a sustainable environment.

The main challenge for me doing this project was time management. I have first decided to write a short novel, and had started an in-depth outline. However, I started to fall behind struggle a lot, because I had assignments for many other subjects. My strengths were my ability to quickly make rational decisions so I don’t waste time. Because I originally wanted to do a novel with a complementary poster but realized I did not have enough time, I quickly decided to scrap the novel and make a poster that one, explains how climate change affects the coffee industry, and two, explains what steps we can take to solve this problem. My weakness was the lack of imagination I had put in and my inability to make posters enjoyable. Because the novel was supposed to be the creative part and the poster was meant to explain the physics, the poster naturally lacked imagination and creativity, but I had tried my best to make the poster. I also had a few technical difficulties, where the SSIS Blog would not work, so I visited the IT office to solve this. Mr Galvez gave me a link to SSIS Blog, which worked for the first few days. However, the link I have received does not work anymore (for some reason), so the technological issue continues to exist.

This is my final project:

Thank you.

I have learnt that production of coffee goes through mainly 7 steps: collection of green coffee, roasting and grinding, extraction, concentration, freezing granulation, freeze-drying and packaging.

I also learnt that the main producers of coffee are Brazil and Vietnam and the main consumers are the Netherlands and Finland.

I have been facing several difficulties in researching - there is a lot of information that I need to research which I haven’t fully completed. I am planning on finishing the research tonight. I have also been facing issues with time management, because I was busy with assignments from other subjects. But because the projects are almost over, I can finally devote more time and focus on this project.

My timeline has been going okay. The research was supposed to be finished by December 6, but was delayed. I have adjusted my schedule so that this will be finished tonight. Other than that, I have partially started my actual project (the novel) in a diary format, to provide an in-depth point of view of the character and her situation.

I am planning on writing a short novel describing a scenario in which climate change has affected the coffee industry, and a complementary poster that explains the physics. My research question is

“To what extent will climate change impact the prominence of the coffee industry,  furthermore the sustainability of the entertainment industry?”

To answer this question, I will be answering key questions such as

“How is coffee produced? How much does climate affect the production of coffee?”

to explore how much climate change will affect the production of coffee,

“How much does the coffee industry profit per year?”

to explore how much the industry as a whole will be affected if climate change negatively impacts the production of coffee, and

“What countries rely heavily on the coffee industry?”

to explore what specific countries will be heavily affected if the coffee industry collapses,

“What is the amount of caffeine an average adult takes per day?”

to explore how much the daily life of people will be affected if climate change halts the production of coffee.

And this is my timeline:
