Titration: It is a chemical experiment in which the concentration of one solution is found by adding a little bit of another solution, finding the point at which the reaction ends, and calculating from that.

Core Competency Reflection: I felt all kinds of joy and sorrow while doing the Lab 20C experiment with my friend Peter Han. I felt the emptiness that comes from making mistakes in the experiment, and the happiness and satisfaction when I found the right value. Through this process, I grew more and was able to prepare perfectly for the remaining journey, especially the journey to finish Chemistry 12. In fact, since I had never done a proper chemistry experiment in Korea, this experience was a new stimulus for me. It was a very impressive experience for me to see the color change to pink when the two solutions were mixed and reached the critical point.

Life Saving Measures

Before you start CPR, you should check an unconscious person by touching his/her shoulders, and talk to them loudly to wake them. If the person is still unconscious, you should immediately start CPR, and call someone to call 911. To increase the saving rate, you need AED. I learned that you need to have confidence while doing CPR. Also, I learned that you don’t need to worry about if you mess up because they will not send you to jail.

I learned that drugs are nasty, addictive, and they have lots of side effects. Also, I learned if you first start having a drug, you can’t stop doing it. Not only drugs, but also vaping/smoking are terrible. In my case, I will never start them because of my dad. He always did a cigarette when I was young, and he changed to vaping in these days. I also realized why I should never do these things, and I promised myself that I would try to stay away from them because I knew they were even more damaging during my school years.

Critical and Reflective Thinking Competency Reflection

I can analyze my own beliefs and consider views that do not fit with them. In the past 17 years of my life, I have always disliked people who smoke cigarettes, vape and do drugs. This belief remains the same and will remain so in the future, so I will never associate with people who do this.

Me card activities gave me new and interesting experiences. I began to reflect on my life once again, thinking about passions, hobbies, and values ​​that I had never thought about before. Therefore, it was a good opportunity to feel the direction and speed of my life once again, and it gave me an invaluable experience where I did not have to worry about what direction to take in the future. That’s not all. I learned exactly what I needed and what I had, which made me humble and grateful for everything. Once again, I feel that the Me card activity is an important piece of the key that should never be overlooked in this class.

For these reasons, the Me card activity taught me a lesson, and although it was not a very great achievement, I think I accomplished something productive and valuable.

I integrate new information, consider constructive feedback, and reassess.

The oral presentation was the most impressive assignment during the ELD 11 class. At the beginning of the semester, I was afraid and frustrated about making new friends. So, I considered making a presentation great, so that students could concentrate on me and my work. As a result, the presentation was successful. People laughed at my joke and my embarrassed feeling suddenly disappeared. After that day, making friends was ain’t difficult for me. Therefore the oral presentation was the most important lesson in ELD 11 class.

Quadratic Equations in Vertex Form

As you can see in the graph y=x2, the vertex is (0,0). There are no y-intercepts but one x-intercept (0,0). The graph is going up and the axis of symmetry is x=0. In the other graph, y=(x+4)2-2, the vertex is (-4,-2) and the axis of symmetry is x=-4. The graph is going down. In the y=(x+4)2+4 equation, the vertex is (-4,4) and the axis of symmetry is x=-4. In y=(x-4)2, the vertex is (4,0) and the axis of symmetry is x=4. There is a y-intercept (0,16) and x-intercept (4,0). In the last equation y=(x-4)2-3, the vertex is (4,-3) the graph goes down, and the axis of symmetry is x=4. There are no x-intercepts in it.

  1. I represent the same mathematical idea in multiple ways using the vertex, axis of symmetry, x and y intercepts, and determine if graphs go up or down.
  2. Vertex, axis of symmetry, x-intercepts, and y-intercepts. I found those words in class notes the meaning of those words, by my memory.
  3. I tried to make sure my information was as easy as possible. I think the most important way to share information is using simple words and if you can, use simple words. The method that I used is the most comfortable way that I can use. I also added different colours to recognize easily and used small numbers to simplify the equation. Not only equations but also parabolas, I tried to make to avoid overlapping. For these reasons, I made my equations and parabolas as simple as I could.
