Capstone Project

I learned how, and why water pollution & water scarcity happen. I did a pretty nice job on my capstone essay, survey, and the video. I also learned that severe water pollution is taking place in China, and China is not putting that much effort on it. If I have a chance to do this project again, I’ll make it more longer with some fancy Powtoon skills.

Even though our group didn’t do well on challenges because of teammate’s absence and file loss (graph), we did our best to draw our graph on Logger Pro and on Desmos. To explain, we measured the distance of how far the ball goes and how high it travels.

Prototype Observations

Prototype Observations Strengths for this Prototype Limitations for this Prototype
35ml of PVA

3g of BS

3ml of Borax solution

12ml of glue

Too sticky and slimy like boogers

Doesn’t block the sound

sticky  
35ml of PVA

5g of gelatin

32ml of glue

3ml of Borax

35ml of starch

Too hard and contains too much water in it

Doesn’t block the sound

none  
35ml of PVA

32ml of glue

3ml of Borax

35ml of starch

Sticky enough and slimy enough

Does block the sound (a bit)

Sticky enough, slimy enough, blocks the sound pretty well  

 

 

Prototype Claim

Use evidence from above observations to complete.

 

Prototype # 4, called Brian, was most effective for meeting our goal because: it at least covers our ears which makes us hear nothing

 

 

 

 

 

 

 

 

 

 

 

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. 25ml of PVA
  2. 12ml of glue
  3. 25ml of starch
  4. 3ml of borax

 

 

 

Reflection

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

 

It was hard to make a polymer that can block the sound. We googled how to make a polymer which block the sound and realized that we didn’t have enough materials in the lab to perfectly finish our experiment.

Elevator Speech

I put quite a lot of effort on writing script but haven’t practised reading. The reason why I chose SDG 6: Clean Water and Sanitation is because I was pretty much interested in contaminate tap water in China and how it harms human body. Next time, I’ll spend my time on reading the script and be more confident without reading script but eye-contacting to the audience. I understand almost 90 % about my SDG and I’ll do more research about specific problems that are going on in China.

Describing Our Polymer

 

 

  1. We are making a polymer that blocks the sound

 

 

 

  1. We want the Physical Properties to include:
  • sticky
  • flexible
  • it should block the sound
  • light

 

 


 

Our Plan to Develop our Prototype

*Prototype = sample or model

 

1st we will…                                                     2nd we will…

Make the polymer flexible by using the super slime recipe

    

 
Test it out and see if it works, if not, fix it

 

Try to add more PVA in order to make it stickier
Try to add less water and more glue to aloud it to maintain its shape

 

Our Method for Testing our Prototype: How we’ll test it to see if it works

 

 

 

 

 

 

 

 

 

Our Method for Testing our Prototype: How we’ll test it to see if it works

Method Why we chose this/How this will be effective
Block the sound source and check if we still hear the sound Make sure it blocks the sound
Stick it on to different textures and check if it maintains its position Make sure it is sticky enough
Change the shape and check if it maintains its shape Make sure it is modifiable

AR: Final Draft

I wrote the diary of a farmer called George who experiences many things during the American Revolution. He learns lot of things such as Revolutions or wars never happen by mortified peasants but wealthy people who want to benefit of it. I wrote this diary because I wanted to show how a normal peasant felt about the revolution instead of the leaders. I learned that even though the American Revolution ended up with American’s victory, nothing has really changed after the revolution.

The Decision to Drop the Atomic Bomb

Many people in the world still discuss about the US atomic bombings of Japan was a good choice or not. This is the reason why history books in every single country are different. Interestingly, even if people were born in the same country, they may have different opinions because both US and Japan also had their own problems and opinions at that time. Even though Japan got extremely damaged by the atomic bombs, Japan started the war and US had to end it rapidly because for US, ending war quickly would save more their soldiers, lots of resources and put US in a dominant position of the postwar world. I think the theme of this book is that there’s nothing in the world which is logically right or wrong because every single person has different opinions and situations.

According to The Washington Post, “The USA was more interested in a quick and easy end to the war than causing untold suffering,” the president of US chose to bombard Japan with their atomic bombs instead of losing their soldiers which was the best choice that leader could decide. For example, according to President Obama, he had no higher duty than to protect the American people which means that protecting nations is the first important thing that every president has to think before deciding. The Washington post also mentioned that Atomic bombs replaced thousands of US bombing missions. Frankly, as the president of America, dropping atomic bombs was the best solution because it replaced thousands of soldiers and tons of resources.

According to “THE US. ATOMIC BOMBINGS OF JAPAN”, Truman’s secretary believed that Atomic Bombs’ devastating power would not only end the war, but also put the U.S. in a dominant position to determine the course of the postwar world, atomic bombs ended the war and placed the USA on top of the world. Eventually, America became to lead the world as one of the strongest country in the world. This fact means that America had lots of reasonable reasons to bombard Japan and benefit of them. Because of American casualties, no surrender from Japan, to put America in a dominant position, to test their new weapon and threaten the world, America justified in dropping atomic bombs on Japan.

Even though American knew that many innocent Japanese will die, American chose to protect their things first with some reasons. America justified in dropping atomic bombs on Japan during the second world war because they had to end the war immediately for their nations, resources and for their benefit. Some may say America is too selfish but caring of nations is the first and best thing to do as the president.

OneDay Dancing Project

I chose dancing as my OneDay Project because it was the easiest thing that I could choose without paying money. We listened to a popular K-Pop group Ikon’s Love-Sceanario at first and we were about to just mimic them but at last we even made some movements.

I learned how to dance during my OneDay Project. Things I could do better are to practise more and choose easier songs. Next time, I’ll choose something else instead of dancing for OneDay.
