Independent Reading Reflection

I have completed 5 full works of fiction for English so far as part of my independent reading. I did not particularly enjoy any of these 5 books, but if I had to choose a favorite, I would choose Ender’s Game due to how solidly-built its setting is. However, while Ender’s Game has an immersive universe, it does not have a lot of creative language which makes it a boring book to read.

While reading, I gave up on two books, both of which was borrowed when I had no idea what other book I wanted to read. I tend to dislike realistic fiction unless they are written well, and these two books were both realistic fiction that was very poorly written. This tells me that I should consider more when picking my books, and that I don’t have to pick a book immediately if I have no books to read.

Grade 9 Engineering Project Reflect & Share

For Grade 9 Science & Engineering’s Engineering project, we were asked to design a product which demonstrates the transfer of energy. My product is a rubber-band powered paper airplane launcher. Here’s an image of the final product:

The product ended up not functioning correctly as the friction caused by the rubber bands rubbing against the sides stopped the airplane from launching.

Here are some additional questions that I will ask myself to reflect on this project.

 

What transfer of energy is shown in this product?

This product receives the kinetic energy of an arm pulling back the launch capsule, and converts that to elastic potential energy. When a finger pulls the trigger using kinetic energy, the elastic potential energy is converted into kinetic energy and would launch the plane forwards, with a small portion being converted to waste energy types like thermal and sound.

 

What would I do differently if I could do this project again?

If I could do this project again, I would plan in 3 dimensions. This product would have worked if thickness wasn’t a factor, but things like hot glue and the difference in cardboard and wood thicknesses made the product fail. Something else I would do differently is to spend less time on Define & Inquire. I spent more than enough time not doing anything and just thinking about whether my ideas are good enough to move to Develop & Plan, which forced me to later spend my first Create & Improve lesson on planning.

 

What do I think I did well?

I think I did many things well in this project, despite the final product not working. I feel like my plan was a good plan, since it is detailed and includes several features which improved the product, such as the aim assist and the trigger mechanism. I also think that I used Affinity Designer rather well, since I never used Affinity before this project. I got a decent grasp on the application rather quickly.

Grade 9 Engineering Project Create & Improve

In Grade 9 Science & Engineering’s Engineering Project, we were tasked with designing and creating a device that involves energy transfer. This is the process I went through to create my Grade 9 Engineering Project’s final product, the Rubber-band Powered Paper Airplane Launcher.

 

 

Day 1: (2023/2/17)

I spent this day mostly planning since I was somewhat behind with my plans. I created a paper airplane and caulculated the dimensions of a perfectly-made paper airplane, so that I can create a product which is suited to launching paper airplanes.

Day 2: (2023/2/21)

On Day 2, I started creating my product. I cut cardboard and created the portion of my product which will hold and launch the paper airplane (what I call the “Launch Capsule”). I used brass fasteners to hold 3 layers of cardboard together. It fit my paper airplane rather well.

Day 3: (2023/2/23)

On Day 3, using Affinity Designer, I created designs for the rest of the components, and used that file to lasercut wood that is 1.5mm thick. This would have gotten me the remaining components I need for my project, but there was an error in the lasercutting instructions and some parts were cut incorrectly.

I also found the axle I will use to secure the trigger mechanism.

Day 4: (2023/2/27)

I noticed that the trigger mechanism does not fit a hand well and is rather awkward to use. Because of this, on Day 4, I redesigned my parts using Affinity Designer, making the handle further from the trigger and also making it longer. Here is a comparison of the starting and updated designs:

Updated handle design:

After that, I noticed that the trigger handle was too far away and that users would have to stretch their hands in an uncomfortable manner, so I moved the handle closer to the trigger, like this:

Day 5: (2023/3/1)

On Day 5, I focused on putting the components together using hot glue. One issue I noticed was that the launch capsule would not fit in the trigger mechanism, but I resolved that by lasercutting more trigger mechanisms and gluing them to the side to make more space.

However, this was not enough. I needed more room for the launch capsule, as the rubber bands on the sides caused extra friction which prevented the launch capsule from launching. This made the product completely unusable. There wasn’t enough time to disassemble and reassemble with more components, however, so my final product did not work as well as I intended for it to.

Grade 9 Engineering Project Develop & Plan

In Grade 9 Science & Engineering’s Engineering Project, we were tasked with designing and creating a device that involves energy transfer. After deciding on my product and its purpose, I started planning.

My plan

Some main features of this plan include:

The “Launch Capsule”

I planned for my airplane launcher to have a part made for carrying the airplane as well as transfer momentum to it when the plane is launched, which I called the “launch capsule”. While this would increase friction and reduce how fast the airplane is launched, there needs to be some sort of buffer between the paper airplane and the rubber band. Paper is fragile, after all. I planned for my launch capsule to be made out of cardboard as opposed to wood to reduce weight, so that the device can shoot paper airplanes faster.

The Trigger & Handle

I planned for a trigger mechanism that is triggered by pulling, along with a handle which will make holding the device much easier. I designed this with an extra piece of wood jutting out to make sure that the finger doesn’t slide off of the trigger. One thing I missed in the plan is the axle I will use to hold the trigger in place while allowing it to rotate.

The Aim Assist

After doing some calculations, I decided to add a notch at the end of the device to assist with aim so that paper airplanes can be launched in an optimal way. Due to the design of the launch capsule, this design will launch the airplane downwards if held parallel to the ground. Adding a notch with a 11.25º offset would make it easier to aim, since now all the user needs to to is make sure that the notch is parallel to the ground when firing.

Grade 9 Engineering Project Define & Inquire

In Science & Engineering’s G9 Engineering Project, we were tasked with designing and creating a device that involves energy transfer.

Purpose: Demonstrate the transfer of energy, and also entertain.

The G9 Engineering Project specifies that this project is meant to show energy transfer, so that is the main goal of this project. Furthermore, I would like for my device to be entertaining or at least interesting since it would be completely pointless otherwise.

Audience: People who would like to be entertained and / or learn about energy transfer.

Project Constraints:

  • A time limit of two weeks for building. This will limit how complex my device can be.
  • Limited materials. This will make some ideas impossible, and other ideas not fully implementable.
  • My lack of skills. This will affect the quality of my product, and also make some ideas off-limits to me.

 

Here are my 3 initial design ideas:

Idea 1: Wooden Marble Track

Materials:

  • Wood, because it is the most accessible material at the ISB Design Center. It is also rather durable.
  • 3D printing material if possible, because it would save the time of cutting and help with precision. However, I don’t have much experience with 3D printing.

Pros:

  • Is not overly complicated / intricate.
  • Is rather interesting.
  • Not dangerous at all.

Cons:

  • Requires materials to come in blocks instead of planks, which is what the Design Center offers.
  • Woodcutting might be time-consuming, and therefore it might not be possible to make a long marble track.

Idea 2: Rube Goldberg Machine

Materials:

  • Depends on the machine. Will require lots of different materials though.

Pros:

  • Is not too complicated to set up.
  • Is interesting.
  • The final product is not very dangerous.

Cons:

  • Testing will take a lot of time.
  • Requires a lot of planning.
  • Requires precise measurements.
  • Is very fragile: one accidental / failed activation and the entire project will have to be reset.
  • Could be difficult to design.

Idea 3: Rubber-band-powered Paper Airplane Launcher

Materials:

  • Paper for the paper airplane.
  • Rubber band(s).
  • Cardboard
  • Wood

Pros:

  • Fun.
  • Not very dangerous.

Cons:

  • There aren’t a lot of improvements to be made after the basic product is finished, so if I finish early I will have nothing to do.

 

In the end, I decided to develop the paper airplane launcher. The wooden marble track simply requires too much time, and the Rube Goldberg machine requires too much planning.

The Price of Energy

This is the video I made for my grade 8 Capstone Project. I think I did a good job: I’m rather new to editing but I think I edited decently on this. I also think I used the right footage and got the point across well.

Anyways, enjoy!

 

A Day In The Life Of A Student During Online Learning

This is my project for the Choose Your Own Drama Adventure unit in Drama class. I recorded and edited to create a skit about the lives of students who learn online.


Questions:

Describe your project.

My project is a skit about what life is like during online learning for students. There’s not much else to it, really.

What was your process in creating this project?

The first thing I did was thinking of a concept for my project. The option I picked was to make a vlog about living in Beijing during online learning. I bent the rules here a little bit and instead did a skit, because I thought that vlogs were probably very boring to make. Now that I have a concept, I wrote a script. I made sure that the script was flexible enough to allow changes in the future. I then revised the script by cutting out parts I didn’t like, and also added some parts to either fill gaps or transition between parts better. Or, of course, for pure comedy.

What did you learn from this process?

I learned quite a bit from this project. This project is one of the first projects I have worked on in which I had to edit a video, and I had to edit a lot of stuff. I would definitely say that video editing is the main takeaway from making this short skit. It wasn’t the only takeaway, however: I also had to record. I had to figure out camera angles that seemed natural, and I also had to think about how the camera is used. One example of this is when I zoomed in on the digital alarm clock: I decided that having a shaky camera would make it funnier and also enhance the idea of panic.

What can you still improve in the final product?

I feel like this project could have been a lot better if I had enough time. I feel like I should have transitioned more smoothly in some places and I think I could have been more coherent throughout the entire video. I also really wanted a credits screen, which is useless but cool. Overall, though, I’m already pretty happy with how this turned out with the time (a bit less than month) and experience (nearly none) I had.

What are you proud about?

The entire thing! Since I am nearly completely new to editing and recording footage with a camera, I am proud of the fact that I was able to make this project in the first place. There aren’t really any specifics as to what I am proud of in my project.

Energy: What Can Be Done?

Energy is an important topic. Image Source

Humans have been using energy for a long time now. From fire to nuclear, the amount of energy humans can generate has risen quickly. Unfortunately, consideration of the consequences of energy production has come later than the consequences themselves. Nowadays, we are faced with a fast-warming climate, a polluted environment, and around 789 million people are still being forced to rely on primitive and unhealthy fire and old-fashioned energy (“Ensure Access”). This situation is what the United Nation’s Sustainable Development Goal #7 attempts to resolve. SDG 7 aims to ” ensure universal access to affordable, reliable and modern energy services” by 2030. It is important to improve energy, as nearly everything modern is built off of it. To reach this goal, we need to see the problems energy production currently has, think about why these problems matter to us, and figure out solutions to these problems.

 

Problems with Energy

Modern energy production has many flaws. One issue is the harm dealt to the environment: fossil fuels release greenhouse gases that damage the environment and climate of the Earth. In fact, energy production is responsible for about 60% of all greenhouse gases emitted by human activity (“Ensure Access”)! The negative effects of energy production on the environment will surely become more and more significant as global energy requirements continue to rise. Also, while cleaner energy has a much smaller environmental impact compared to traditional energy, these forms of energy are simply not cheap enough currently to support the economy. In fact, Europe’s recent attempt at switching over to clean energy has indirectly caused food prices in many countries to reach their highest in ten years (“The Consequences”). Another problem is clean energy’s reliability. Many clean generation methods rely on the weather: for example, solar energy depends on the sun not being covered by clouds, and wind energy depends on the weather being windy (Darwall). Currently, energy just has too many issues that need to be resolved.

 

Why does energy matter?

Energy has massive impacts on the lives of everyone, and there are many reasons why energy needs to become more accessible and cleaner. For one, it is used for pretty much all aspects of modern life. According to the United Nations, energy impacts everything “from businesses, medicine and education to agriculture, infrastructure, communications and high-technology” (“Ensure Access”). The more expensive energy is, the harder it is for poorer people to have any of that in their lives. Statistics from the United Nations also say that currently, 13 percent of the global population lacks access to modern electricity (“Ensure Access”). Affordable energy would allow more people to access electricity. Clean energy would also help reduce pollution and harmful emissions, which has “harmful impacts on people’s well-being and the environment” (“Ensure Access”). Clean energy directly affects your health in this way. Finally, clean and cheap energy would provide more job opportunities, create better facilities and supply more resources (Leahy). Jobs, better facilities and resources influence everyone. Non-polluting and cheap energy is a subject of top importance, and all these reasons show that.

 

Solutions to the problems

There are many ways to improve energy and energy production. One thing that can be done by everyone is simply to use less energy. According to the United Nations, you can save electricity by “turning devices off when they are not used” (“Ensure Access”). Another way to help improve energy is for investors, companies and governments to invest in the development of better energy sources such as clean energy (“Ensure Access”). As energy generation methods are researched, energy will become cleaner, cheaper, and more reliable. The transition away from fossil fuels and towards more renewable and sustainable forms of energy is also an important step, since our reliance on traditional energy sources is one major roadblock in fixing today’s climate issues (Ramirez). Businesses can support this change by aiming to meet their energy requirements entirely with sustainable energy (“Ensure Access”). There are lots of ways individuals and groups can help make clean, cheap and reliable energy both a possible and feasible future.

It is important to understand the issues with energy, realize the consequences of these issues, and fix these issues. We have realized the faults of energy too late and allowed the consequences of energy to occur, but better late than never.

The Tory’s Story

Bob Andrews, his name was. Fought in the American revolutionary war, they said, and for the wrong side. People judged him because he was a Tory, but that’s alright. Even Tories had stories to tell. Bob Andrews had his journal: three entries, spanning multiple years, which gives a peek into what his tale was.

Was the War Worth Fighting?

The American Revolution changed a lot, for many people. One of the most important changes was the fact that after the revolution, it was possible for anyone to rise in social status if they worked hard enough. This contrasts strongly with how it was before the revolution: before, if a person was born a status they would stay with that status. Another change was the method of governance. The revolution abolished the monarchy and instead replaced it with a Republic. There is still a person in charge of the country, but he is restrained by several others: the members of the congress. Average citizens also now have a say in the governance of the country through the new voting system.

Not everything changed, however. There was still one central government with power. People who faced oppression such as women, Native Americans, and African Americans were still mistreated like they were before the war even though many had helped the Patriots win the revolutionary war.

While the war did not bring freedom and equality for all, it did allow for much better social mobility. The American Revolution also removed a central figure who has the potential to become tyrannous. Overall, the American Revolution was definitely worth it in the end.

When you Tax Without Representation

The American Revolution is a revolution that occurred over the span of twenty years. It was sparked by the Parliament’s decision to tax the colonists, and ultimately resulted in the separation of the colonies from Britain and the creation of a new country. What are the causes of the American Revolution? What are the aftermaths? This video answers these questions and also explains the key events of the American Revolution.
