Summary Draft #1

The article “ How green steel made with electricity could clean up a dirty industry.” written by Crownhart (2022), describes the creation and the use of green steel. One notable difference between steel and green steel would be their production methods. Currently, steel is produced in fossil fuels where coke, a coal-derived material, reacts with iron ore, a mixture of iron oxides and other minerals. As a result of this reaction, liquid iron is formed, and carbon dioxide is emitted. The molten oxide electrolysis (MOE) approach - used to produce green steel, uses electricity to pass through a cell containing a mixture of dissolved iron oxides, other oxides, and materials. Unlike the previous approach, oxygen gas is emitted instead of carbon dioxide.


As steel is used in all parts of the world, it is expected that there would be a high demand. This, in turn, would lead to a higher production rate of steel. Due to this, the steel industry produces approximately two tonnes of carbon dioxide emission for every tonne of steel produced, adding up to about 10% of such emissions globally. With green steel, however, such problems would be solved due to the emission of oxygen instead of carbon dioxide, reducing the carbon dioxide emission levels significantly.


Despite the differences in their manufacturing processes, green steel is expected to share the same properties as regular steel. This means that people would be able to enjoy the benefits that steel offers while combating global warming.

    In my opinion, Jazlyn's summary is good as she started off by citing the source which gives me, a reader some confidence as it is from a reliable source. She has stated the usage and manufacturing process of steel which is great. In addition, she ended the summary on a good note by stating the benefit of green steel.

Descriptive Reflection: Self-intro Letter

Subject: Self-introduction email Dear Professor Blackstone, My name is Catalan Jazlyn Mei Torres but feel free to call me Jazlyn. I am a student from your Critical Thinking and Communication class (S77) and I hope that through this email, you will be able to learn more about me. Having graduated from polytechnic with a diploma in electronic engineering and majoring in mechanical design and manufacturing engineering in university, I often receive questions as to why I changed my course of study. The reason for this would be my internship in Omnicam Technologies. During my stint in the company, I was assigned the role of a programmer and I was in charge of displaying the data that was collected by the energy monitor in a visual format. While I was coding away, I noticed that one of my colleagues was creating a housing for the energy monitor using computer-aided design (CAD) software. Seeing this, I got interested in 3D modeling and I would even volunteer to help my colleague with his mod...

Critical Reflection

In my introductory letter, I mentioned the two goals I wished to achieve for this module were improving my confidence and delivery during my presentation. I am proud to say that I achieved these goals in 13 weeks. Through the various opportunities given to us in class to present, be it elevation pitches, mock presentations, or even standing up to read from the screen, I was able to gradually improve my confidence and delivery. Eventually, I was able to feel comfortable with public speaking. This was apparent to me during the oral presentation, where my team and I had to present our proposed design solution, ParkingGoWhere. Compared to my previous presentations, where I stuttered and rushed through my slides, I found myself going at a comfortable pace with little to no stuttering. As such, I believe that I was able to deliver an impactful presentation along with my teammates.  In addition to honing my presentation skills, I was able to work on my critical thinking skills. Adopting t...
