Science Engineering Project Blog Post #4

On the final day of the project, I finished wiring my product and glued everything together. The fan was functional and successful. The solar panel and power button were wired correctly, so users and control whether to turn the machine on or off.

Energy transfer in this project:

The solar panel converts the heat energy from the sun into electrical energy. Which then powers the motor, turning into mechanical energy. Here is a video of the final product.

Video of Product

My areas of success were how the final product was decently aesthetic looking. Also, my wiring and soldering were all done correctly. Everything went according to plan even though I had to scrub my first idea.

I could still improve on the functionality of my product. It works, but it might act more like an accessory than a practical, legitimate fan. I was so focused on the basic design of the product, I did not think about the fans. That is an area I still need to improve on.

All in all, this project still as an positive impact on the environment. Even though it might not be as powerful as an actual fan. It still uses sunlight to power its self. Therefore, it does not require batteries or disposable methods to receive power. The client can enjoy a little fan accessory without using any batteries or house electricity at all.

Science Engineering Project Blog Post #3

I began to make my first prototype out of cardboard. My original design of a portable solar power bank was scrapped due to a lack of materials. My new design was going to be a solar powered motor with an on/off switch. At the time, I was still thinking about what to put on my motor. The cardboard prototype was only to test my wiring and basic structure.

First, I made the shell for the basic design. Then, I added a piece of cardboard to the motor to mimic the fan.

I put the solar panel on the back to test my wiring and if it is functional. My prototype was a success and I decided to start working on my final product. It will be made out of wood, a better material than cardboard.

By the end of the day, I managed to finish 70% of my project. I made 6 wooden sides to create a complete square. I cut a hole on one side to fit the motor, and another smaller one on another side for the power button. After hot-glueing motor and power button, I glued on two more sides. Soldering was a bit slightly complicated because of the tight space. Now, I just need to glue the top and bottom then wire the solar panel.

Solar Power Bank Plan

The link above is my original plan for the Solar Power Bank. But I did not have the required materials to complete my design. Therefore, I quickly made thought of a new design, a small solar powered accessory fan. This design required a power switch, solar panel, and motor complete with a fan.

What is This Engineering Task?

The main goal of the engineering task is to design, build and refine a device that works within given constraints to convert one form of energy into another form. These devices can range from small toys to renewable energy. The device should have a purpose and a client, it should also be functioning and look aesthetically appealing. The end product will have to be original, safe, and environment friendly.

-Project Ideas-

Solar Powered Car Toy

-Renewable energy
-Converts energy
-Safe and original

-Lacks of purpose
-Needs to be durable

Solar Power Bank

-Very practical
-Renewable energy

-Materials are hard to find

Hydroelectric Generator

-Renewable energy
-Easy to find materials

-Doesn’t generate enough energy

Capstone Project

The Capstone project was a great learning experience for me. During the research stage of the project, I learned new information about China’s energy production. It was really interesting to study China’s renewable energies and fossil fuels energies.

This project helped raise awareness for the energy problems that China is facing. Power depletion and pollutions are the main worries for China, our documentary talks about there issues and addresses it to the viewers.

My values, opinions, beliefs stayed the same. I believe still that China should be transitioning to alternative energy.

Surveying students in ISB was a fairly easy task. Since I know students of the ISB community, it was really easy to talk to and survey them.

If I could do this project again, I would put more time into research. In my opinion, research was the hardest part of the Capstone Project. I feel like I could still do better research if I were to do this project again.

For the next 8th grade students, I would recommend focusing on a topic you enjoy. I choose renewable energy and extremely enjoyed researching and learning about my topic.

Very Interesting Catapult Challenge

This project required us to create a catapult that is able to fire a ping-pong ball at a consistent and accurate distance. We ended up making three prototypes, each having their own characteristics. The first prototype was a basic and simplistic design. It worked at an average consistency, but the catapult lacked power. Therefore came our second design. The second prototype featured more of a launcher design, similar to a crossbow. We based our third design on the second prototype. The build quilty was improved, and we also added a better firing mechanism.

-Prototype #1

Pros: Simple, consistent

Cons: Lacking in power



-Prototype #2

Pros: Powerful

Cons: Not consistent due to poor build quality




-Prototype #3

Pros: Consistent, powerful

Cons: Hard to fire freestanding

The challenging part of the project was building the catapult. We had to test and changed different parts to keep improving our accuracy. I learned that trial and error is a crucial part of making the perfect product.

The Power of Censorship

Book Picture by Austin Lu


In the society of Fahrenheit 451, firemen burn books rather than putting fires out. Montag, the main character, is a fireman. The people in this futuristic American city do not read books, have meaningful conversations, or enjoy nature. Instead, they endlessly watch television and drive fast. Even though Montag’s job is to exterminate the books, he has developed a slight interest in them.

“At least once in his career, every fireman gets an itch. What do the books say, he wonders. Oh, to scratch that itch, eh? Well, Montag, take my word for it, I’ve had to read a few in my time, to know what I was about, and the books say nothing!” (Bradbury, 30)

This brings me to my thematic statement, “Censorship only empowers curiosity”. This is represented when Montag secretly takes a few books from a house he burned down.

My Multimedia is a minimalist art piece that I created. It represents the books being burned in the broken society of Fahrenheit 458. The match illustrates the censorship trying to banish the books from ever being read.  The white colour of the pages of the books is shining bright, almost like it’s reaching out to you, calling on you to read it.
All in all, censoring and burning books only empowers people to become more curious about what the books contain.
