Prototype Observations

Prototype Observations Strengths for this Prototype Limitations for this Prototype
Prototype 1:

Noodle slime

The polymer was to stringy, it wouldn’t stick together and would fall apart, just like homemade noodles The prototype wasn’t too sticky and was very stretchy. It couldn’t stick together at all so when it would have to stick onto pans it would not work
Prototype 2:

Noodle Slime 2

The polymer was very similar to the first noodle slime however it was thicker It wasn’t very sticky It could not stick together and was too thick to be able to stretch
Prototype 3:

 

This slime was too sticky and wouldn’t hold itself It was very thick and sticky The polymer was too sticky and wasn’t stretchy at all. It would break apart right away.

 

 

Prototype Claim

Use evidence from above observations to complete.

 

Prototype # __4__, called _____Heat Reduct∞_______________, was most effective for meeting our goal because:

It was thick but stretchy and was sticky enough to attach itself onto pots and pans, it was very durable and had a great grip.

Reflection

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

 

The process was very difficult. We initially wanted to have slime be able to cover over someone’s hand as if it was a glove. We tried various ways to make the prototype perfect but in the end failed and had to go back to the drawing board. We then all decided to go with a polymer that could be molded into any shape the customer wanted it to be so it would be able to grip the pan, pot, or cup, perfectly. We played with our, materials and how much we used so being able to find something that was useful was a bit difficult. We then tried going to the internet for some solutions but then found out that we could never trust the internet. In the end, we were successful in what we made and was able to have a perfect conclusion even though it wasn’t what we wanted in the beginning.

It will help them by being able to touch the burning pan, hot skillet or anything that’s hot without burning or hurting themselves.
Possible Target Market Audience #2:

*just in case you have more than one target market audience

·       Anyone handling anything hot

 

The same with the first targeted audience.

 

Describing Our Polymer

We want the Physical Properties to include:

  • Stretchy
  • Non-stick
  • Resilient to heat
  • Thick

 

Polymer Characteristics We Are Looking For

Polymer Characteristics Why this is important
Boogers Stretchy When you are handling a hot pot, you will be able to wrap the polymer around it.
 

Gloop

Thick When holding something hot you don’t want a thin layer of anything to protect you from the heat.
Gloop Not sticky This is so the polymer doesn’t stick to the pan or item that was held up with the polymer

 

Our Plan to Develop our Prototype

*Prototype = sample or model

 

1st we will…                                                    

Create the prototype by mixing different solutions into the mix

     2nd we will…

Test it onto real hot pans and pots

3rd we will…

Try to see if our product could be thick and stretchy at the same time

Finally 

Shape the polymer and redo it to see if we wrote down the correct instructions

 

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
We first wrapped our polymer around a mug that was filled with hot water. We chose this to examine how much the polymer could hold and if it would slip.
We held a pan that has been on the stove for 5 min with the polymer We did this to see how the polymer resisted heat for long periods of time
We then held a hot pot with the polymer We tested to see if the polymer could hold the weight of the pot and not slip or melt.

Synthetic VS. Natural

What are synthetic materials?

They are materials that are not man-made.

 

 

Give 2 examples of synthetic materials.

Plastic

Glue

 

What are natural resources?

Resources that are found naturally

 

Give 2 examples of natural resources.

Fossil fuels

Animals

 

Polymers and Where They Come From

What is a polymer?

 

a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together

 

 

 

Give 2 examples of synthetic polymers and the natural resources they come from

Synthetic Polymer #1

Plastic

 

What natural resources does this come from?

Animal horns or animal milk, insects and trees

What would we use this synthetic material for?

Mostly everything in our lives

Synthetic Polymer #2

Glue

What natural resources does this come from?

Horse hooves and bones

What would we use this synthetic material for?

Sticking things together.

 

 

Chemical Reactions

 

How do natural resources go through a chemical reaction to become synthetic materials?

*important words to think about…polymerization, monomer, polymer

 

•Their natural state has been processed and chemically changed through polymerization to turn into a synthetic polymer.

 

What is a monomer?

•A monomer is a molecule that is able to help in the process of polymerization

 

What is polymerization?

 

•polymerization is a process of bonding monomer molecules together

Responsibility & Leadership

I found leadership in the NIH project where I helped lead Clara and my’s project.

I found responsibility when I was able to finish my antibodies video.

Inquiry & Critical Thinking

For my work on inquiry, my Chinese Cultural Revolution class and I have been studying about this revolution for 3 months. We had several visitors who all couldn’t speak English well. I have used my inquiry skills to ask the people questions and was able to translate it from Chinese speaking to English writing.

Example:

~Jacey’s Notes ∠( ᐛ 」∠)_~
• The kids were crazy then
•Whenever the kids hated people or were demanded to beat people they would because they had nothing to do and ever since they were little they believed in MaoZeDong even if they didn’t know what he was saying they believed in him. 
•THESE PEOPLE CRAY CRAY
•by 1967 the radical cultural revolution dominated the government the members were, Lin Biao, and mao’s wife: Jiang Qin
•She would often appear as Mao’s spokesperson and gain great power
•Liu Shao Qi tried to moderate events but he would always side with Mao. He tried to protect people but his power had his limits. Many close to him would soon be brutally attacked
• People from the cultural revolution group told the kids to drag out Liu Shao Qi and Deng Shao Ping and overthrow him. 
•Because of Jiang Qin’s fame when she talked trash about Liu Shao Qi everyone else agreed. She likes trash talking.
•April 1967 Red guards tricked wang and said her daughter was in an accident but they took her into a crowd and dressed her as a whore and humiliated her.
For Critical thinking, it also had to do with the study of the Chinese Cultural Revolution where I had to use Critical thinking to imagine myself in the people of that time’s shoes.

Innovation & Creativity

I’ve planned out and edited the humanities project of the Cultural Revolution in plain English. This claim is for the Creativity skill.

Evidence:

I’ve joined the yearbook where I create pages for the yearbook which helps my innovation. NOT CREATIVITY. For reasons which I will explain now.

 

Revolutionary Voices Journal – Chinese Cultural Revolution

The past few months my partners and I have been studying the Chinese Cultural Revolution. After being assigned to do ‘The Chinese Cultural Revolution in Plain English” we then were assigned to write in a person in that time’s point of view, separately. My character doesn’t say her name in all three journals but she is called Tong Hua Ming. Hua Ming was once a little girl who thought she was in the safest surroundings in the universe. She was comfortable and happy until the Red Guards barged in.

During the time each journal gets shorter, this is because she is writing during the revolution and Red Guards are lurking in every corner. Whenever she rights she must do it quickly and hides it under her floorboards. The last journal of the three is the last one she ever writes. This is because she wants a fresh start, she doesn’t want to look back and remember her broken childhood.

I hope you enjoy and learned something!

Blog Post – Smarter Than You Think

The book: Smarter Than You Think, asks one question and one question only: Technology is changing the way we think. But is it for the better? The answer the author clearly states is: Yes, technology is changing our thinking for the better. However, I decided to come up and explain how the way technology is changing our minds isn’t exactly for the better. Comfort and convenience is one of the biggest thing we spend our time and money on, we also rely on these machines so much that we can’t even imagine what life would be without them.

 

Comfort and convenience is an extremely important thing in our current state of living. We depend on these machines to make our lives easier. Of course, being myself, comfort and convenience is not such a terrible thing. Conveniences such as transport and easier communication are improvements to our world. Yet, these conveniences change our mindset turning us lazy. Such as calculators, mental math is an important and ongoing challenge in the academic mathematical system. When we use our own methods and ways of thinking we use our whole left brain to think up the answer, it also helps our memorization. However, when using a calculator all you need is some fingers and numbers.

 

We also rely on these machines and conveniences a bit too much. As our world grows and several generations have passed we would rely only on machines. Such as the internet, a small box in the corner of the room that connects us to all sorts of websites, videos, and other things that has been added to the mystical world of the internet. We can also communicate with others from across the globe, but without the internet what would we do? Of course, there are a million things you could do without internet but our minds doesn’t immediately go to the fact that you could do a million things without internet.

 

Yes, without these machines our world would spiral down into complete turmoil. Machines and technology is the future, we would have to rely on and use these things that are given to us. However, without these things we become less ‘human’. We rely so much on machines that we could basically be cyborgs. Yes, these things that we invent and encourage are achievements to our species and they aren’t exactly listed as conveniences. Their convenience is listed as helpful and can cure diseases.

 

Even if technology now seems to be improving our mindset and is molding it, it’s molding our thinking to be compatible with the machine, having us rely on technology more and more.

 

Chinese Cultural Revolution In Plain English

Diligently, my teammates and I have been studying continuously on the Chinese Cultural Revolution to better understand the history of the place we are currently living in. After studying for so long we were assigned to do a common craft video. A common craft video is a visual explanation that’s simple and should be under 6 minutes. There were many problems with time management and one of our teammates being gone for two days straight we stressed for an extremely long amount of time. However, we were able to pick ourselves up and finish recording, drawing, and editing. In the end, we’ve learned a lot about China and had fun along the way. We also learned how to work through stressful situations and collaborate with each other. This project was both entertaining and a painful experience.
