Industrial Revolution

What was the most important aspect of the Industrial Revolution?

Coal extraction was the most important part of the Industrial
Revolution, and without it, life today would not be the same. Without the extraction of coal, things like steam engines, machines, iron, and metal devices would not be present and active in modern time. Coal extraction changed the way materials were produced and delivered by powering machines and transportation to efficiently finish the job. Industrial production would still be developing if coal extraction wasn’t used as a tool to help polish and improve the way the systems worked. Agricultural produce was transported to the city or the industries by trains/the railways which are made from iron smelting, that run on steam power, which would not be possible without coal extraction. It’s all a system that connects and at times there are doubts on what started it all, but without coal extraction, most of the major aspects of the Industrial Revolution could not exist.


Drama Puppetry – Lee Randall

In drama class we had a workshop on puppetry with Lee Randall. I learned many things from him and how to use a puppet correctly so that the audience would fully believe and understand that it was alive.

I learned that the most important part of a puppet is its eyes because they draw the most focus. You need to make it move with a purpose.  The person who is in charge of this movement is the person controlling the puppet’s head because they are in control of its eyes and where it is looking. Another key thing to remember is to show exaggerated breathing or deep breaths.

In drama and other subjects we did things that helped us in this workshop. Like in P.E, we used levels in our dance unit and you need to use levels with a puppet and show its weight. Also, earlier in drama, we worked in pairs and one of us was the puppet, making it slightly easier to know how to manipulate and help express feelings and a story from it.

 

Materials in YIS Technology

There are many different minerals and materials in the technology today. Each has a different purpose and can be in different electronics. Today I will be focusing on the materials in an iPhone.

Identifying elements and compounds used: 

There are numerous materials in iPhones, and I’ll mainly be talking about three. Those three are: terbium, lanthanum, and praseodymium. They work in similar parts in the phone.

Terbium is an element used in an iPhone. Its symbol on the periodic table is (Tb) and its atomic number is 65. It is mostly found in the phone’s colored screen and vibration unit. It can be a very good alloy of dysprosium and iron, which helps move a magnetic field which is why its found and used in speakers.

Another element in an iPhone is praseodymium. Its symbol on the periodic table is (Pr) and its atomic number is 59. Praseodymium is used in the phone circuitry, the coloured screen and speakers. They use it in the color screen because it produces arc lighting and gives glass a gentle tint, which is the screen of a phone.

Lanthanum is also used in iPhones. Its symbol on the periodic table is (La) and its atomic number is 57. It is mainly in the phone circuitry and the color screen. It serves in other products such as lamps, projectors and studio lights because of its many catalytic applications and accompaniment with glass. Which basically means it can conduct a big amount of electricity and make the rate of chemical reactions faster without going through any major change in chemicals.

Issues/Effects:

There are a few issues that surround lanthanum. It is a very rare and has to be mined with great care. It tarnishes quickly when exposed to air and could cause health risks if exposed to it for too long. It is found in monazite and bastnäsite ore, which is mostly mined in China, (the statistics are very high with just under 100%) it is sold at a very high price because of its importance in the electronic and automobile companies and industries. There used to be multiple mines in different countries, but these were shut down in 2002 because of environmental issues, therefore greatly limiting the supply. Because of its rarity, it costs companies and governments a lot when phones are just thrown away or never used because of customers newfound attractions to the newer models. With all the recent technology and products, old ones are being wasted, which in turn, wastes the minerals in them.

Recommendation: 

I think that we should raise awareness on how to recycle phones to help conserve and sustain the minerals used in them. It doesn’t matter how, we could make posters, share articles on social media, talk about it, create an after school activity or service group. However you want to help, just talking about it can make a difference. Recycling phones is a truly helpful idea that is present in many communities and countries. Older phones can be utilized by charity groups who serve underprivileged families, senior citizens, or victims of domestic violence. These individuals would not have the means to communicate without charitable organizations, and we preserve the life span of the technology and the resources within them.  We should also use phones to their full extent, because many phones are just neglected once a newer version comes out. Constantly buying new phones when the old ones still work is foolish, because then the issues just come around full circle. Even phones that are damaged or non-functioning can be sent back to the manufacturer and working parts can be salvaged to refurbish damaged phones. This prevents perfectly good minerals from being cast away. Saving one phone can go a long way, and if we get groups of people to each recycle at least one phone, imagine the positive affect it can have on the mining industries.

Empires End Unit Reflection

Backward-Looking: How much did you know about the subject before we started?

I didn’t really know much about the subject of Spain colonizing Cuba. I knew it happened in history and that’s all. But when I started researching with Evan I found out that it affected my country (the Dominican Republic) as well, and that my culture was similar because it was conquered by Spain as well. It was really interesting and it showed me that things are connected even when you can’t see it at first.

Inward-Looking: What was especially satisfying to you about either the process or the finished product?

The process of making the powerpoint was a long one. I thought it would be easy and we could just find images, site them, and put them on the powerpoint and that was that. But the CC Search was introduced and that made things a bit harder. I wasn’t used to it so I would search my topic and find images that I wanted but they wouldn’t always be available or I would forget to use it and find the perfect image and get all excited but my partner would ask me if it was from CC Search and….it wasn’t. So my first experience with CC Search was a bit rocky but in the future I think it will be easier to use and be super helpful. So that’s what I found satisfying in the end. Seeing all the beautiful cited pictures in the powerpoint.

Outward-Looking: Did you do your work the way other people did theirs? 

We did our work slightly different than most people. I didn’t notice this at first but when we were seeing all of the end results I found that ours was different that everyone’s, excluding the one or two other pairs that looked the same. I don’t think that affects our grade, but it was kind of surprising seeing that people interpreted the instructions and TSC differently. We were also a little behind and that kind of made me nervous because everyone was doing the next step and we were still struggling with research, but we put in extra effort during bre ak and we easily caught up with everyone else.

Forward-Looking: What would you change if you had the chance to do the piece over again?

If we had to do this task/unit over again I would probably make a few changes to the process. I was nervous that we wouldn’t complete it on time and I wasn’t quite happy with how the work was distributed. But once things were speeding up, I knew I could rely on my partner to do things we needed or to help complete a part. I think I would make an action plan or set goals for class time so that everything would be planned out and there would be no panic.
