Engineering Project Update 3

 

 

This ^^^ is the beginning of the music box. I started to saw and sand down some keys that will hit the glockenspiel pieces.

This was the “finished” product of my music box. Of course, this project has not finished but it was because of the lack of time. Everything that was planned out was in perfect order it was just the amount of time that stopped the production.

Engineer Project Update 2

Music Box Plans

This is my design for my music box. Sizes will be tweaked a bit as we progress.

Music box bottom

Above is the diagram of the bottom section of the music box where it is storage space.

Frozen notes

Above are the notes that were supposed to be for the drum of the music box. They were in the notes of the chorus of “Let it Go” from the movie “Frozen.”

Music box top

This is the diagram for the case that is on top of the initial box that is supposed to be storage. The top box is the box that holds the drum and the glockenspiel.

 

9th Grade Engineer Project

Our job is to make a toy. When I was younger I was infatuated with something called a HEXbug so not I want to see if i can make one as well and change a few things as well.

ThiI is a video where someone else created their own HEXbug.

STEAM Project: Tiny Dancers (A Homopolar Motor)

https://www.ehow.com/how_6831339_make-wind-up-music-box.html

After some thought in my project, I have thought about making a music box/ Hexbug track that will have the Bugs move around in a track that is built onto the music box while music plays. I also might add the twirling ballerinas for effect.

These are where I got my notes for the music from.

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.

Polymer Journal 2-3

Our Goal:

The goal of our polymer project is to help people who cook, bake, or touch anything hot with their hands feel safe.

Target Market Audience

Some Examples:

 

Adults

Parents with small kids

Elderly

Kids

Teens

Boys/Girls

Teachers/Businessmen/Shop Owners

Pet Owners

Travelers

 

Target Market Audience How will this help them?
Target Market Audience #1:

 

·       Adults

 

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.

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.
