Report Template- Metal Technology- Prince Rupert's Drop

10 MTY Prince Rupert’s Drop Introduction -

 What is Prince Rupert's Drop? 

A Prince Rupert’s drop occurs when you have some molten glass melting off of a tool of any kind into a container filled with cold water. Once it cools down, you're left with a piece of glass that is sorta shaped like a water droplet, hence the name. It is methodically peculiar because the front end of Prince Rupert’s drop is industructictable when hit with a hammer but yet, it can shatter with a single puncture to its tail. 

What makes a Rupert's drop so strong under compression? 

To understand the layers within Prince Rupert’s drop, you need some idea of what these layers comprise. Molten glass is bigger the more heat within because of the thermal expansion coefficient that assures us that heat decides how big the glass will become, solid glass is stronger, stertier glass, and cooling glass for when alternating between both other states. The cooling glass shrinks and pulls in on itself. Think of it as a handful of microminiature parts of glass within trying to unite with the other kinds of glass around itself. The outside of the drops form acers when it solidifies in the cold water when it changes into cooling glass as soon as the first layer is dropped. The drop becomes extremely high because it is circular in form, so while the outside is solid the inside cools down while compressing to make it much stronger because of the tension build up. Once it hardens in a full solid as soon as it's completely cooled down, it becomes a Prince Rupert’s drop. 

 What causes Rupert's drop to shatter?

The Prince Rupert’s drop shatters when a link on the tail is cut, the storend up testion is unleashed, it travels down the line feeding of its own energy. The difference between a chemically induced reaction and Prince Rupert’s drop reaction is that it isn't chemical potential energy. Prince Rupert’s drop has instead mechanical strain energy. 

 How fast does Rupert's drop shatter? 

 The V failure front is the measured velocity of how fast it shattered.

 What safety equipment do you need performing these tests?

• Hammer
•  Metal rod for glass 
• Cube Metal bucket 
• Anvil 
• Lighting 
• High speed camera & miro camara
• A phantom v1610 
• Industrial Tweezers 
• Eye protection goggles/glasses/face mask (main safety) 
•  Polarized glass/Polariscope (To research the inner layers)

Lesson Plan
Different positions in building a bridge

Summary

1. Understand the different positions in designing and building a bridge

2. Build a team consisting of one of each specialists

Implementation

Learning Context

Research the following four job titles.   

• Civil Designer: Te Awa Doull

• Civil Engineer: Te Awa Doull

• Bridge Welder: Dillon Hayward

• Resource Manager: Dillon Hayward

Procedure

Make a copy of this document. 

Write a short paragraph describing your team. ( Name of your team, team members and who is responsible for which job.)

I, the emperor, will devise the resources to the engineer to build the construct while checking that It is all in one piece- Dillon I am a gay nobal men, I work out the planning all on my own while making sure its stable- I am batkun B Cun

Write a short description of each job's responsibilities. (Check Bridge Building Rules Document)

The engineer, it is they’re job to build part of the structure and give it to the welder to then start building the other part of the structure. The Designer is the one in charge to make sure it’s a design that will be stable and strong once built. The Welder, Is the person who is incharge of the connection of each of the pieces applied to the constructed to ensure that everything Can carry the weight. The Resource Manager, The guy who calculates the bridges cost, making sure to not spend too much by getting the exact measurements.

Insert a photo from the internet to show what type of bridge design your team will be aiming to replicate.

After completing this document, Share it with your team members.

SST 2022 year 10 topic, goals setting and reflecting.

These are my goals for 2022 

1. When I need help I know to ask my matua/whaea for example or search on my own.
   At the end of this term, I want to be able to say that I achieved my goal of achieving merit or higher.
   
   
2. One piece of advice for myself this year is to have a reflective journal to remember the important lessons I had studied.
   
   
3. One thing I was proud of from last year is that I managed to prepare myself to get through the year on time and also had over average scores on tests.
   
   
4. My main focus this term is to recover myself by gathering information I may need for the rest of the year and settle down/recuperate myself to be engaged. 
   all my subjects while increasing my confidence. 
   
   
5. These are my action steps to help me get there:
   Organize myself to be sufficient and attentive.
   Participate in more activities for more confidence.
   Help myself to the information within the library.
   Getting myself out of my comfort zone by playing in a sport( either soccer or hockey).
   Become a role model and a good friend.

year 9- message on consumerism. 2021

 Main message about consumerism from this video

Consumerism

In my opinion, It is an absorbing video that has many captivating insights about the consequences of consumerism, it just as well represents future side effects too. We are digging the earth for all its resources yet most of it is used but then wasted after its years or gone and sent to a landfill. While we gather the resources of our devices, we are also ruining our environments. Ecosystems in the process are forced to leave or killed in their homes because people are destroying their habitats. These are just a few examples of people who harm the things that make places truly beautiful for their own self centered benefits.
