On Thursday, November 18, I observed Introduction to Physics taught by Dr. Martin P. McHugh. I really disliked physics before I observed this class. However, after I observed this class, I changed my mind. I think physics is a very good subject for our daily life. It relates with our earth, such as the greenhouse effect and global warming. I also learned new knowledge about quantum physics.
Dr. McHugh taught us about the greenhouse and global warming with questions. For example, ice in the Antarctic is . . . ? The answer is "melting," confirming global warming predictions.
After a quiz, Dr. McHugh taught us about the atom. I felt confused, but Dr. McHugh showed PowerPoint pictures to explain. Those pictures made us understand the difficult knowledge, such as the nuclear model of the atom.
I especially enjoyed this class, and I changed my mind about physics. I enjoyed learning about a new topic. I thank Dr. McHugh because he made me not be afraid of physics.

On Thursday, November 18, I observed Chemistry in Art taught by Dr. Kathleen T. Crago and her son Dr. Edouard Louis Crago. The topic of the class was chemical interactions that can be used in art. I did the experiments with the professors and classmates.
The first experiment was to imprint a pattern onto a sheet of copper. I put a sheet of copper into a liquid solution for one minute. Then, I put it into a cup of water for thirty seconds. Hydro wax covered the copper sheet. Next, I drew a pattern on the sheet of copper with a needle. After this, I repeated the first two steps and then put the copper sheet into another liquid solution. After thirty minutes, I removed the copper sheet, stripped away the hydro wax, and washed the copper sheet. The experiment was successful. My pattern was on the copper sheet.
The second experiment was to change the color of aluminum strips to make them beautiful and use them in art. Dr. Edouard Crago put an aluminum strip into a liquid solution. He changed the temperature of the liquid, and the aluminum strip became blue. We can change aluminum to many colors by changing the temperature.
I was interested in the experiments, and I learned a lot easily in this class. We can make beautiful things in the Chemistry in Art class.

On Thursday, November 18, I observed Business Communication taught by Dr. Frankie J. Weinberg. On that day, the professor didn't teach. Instead, the students presented the websites they had created to introduce themselves to the class.
The first student's website looked classical. He had put some pictures about himself wearing a suit and shaking hands with people. He said that he likes boxing and watches all the boxing matches. His website showed a video of himself boxing. He also shared experiences about his first job and about how to study.
Other students presented their websites. But one student's website was different. This student used hip-hop style to present his website. The student sang a song about himself. It was so cool. The professor was so surprised. I liked it because this student created something different, not like the other students' websites.
After class, the professor was friendly and helpful. He chatted with me and welcomed me to join his class. This gave me good memories.

On Friday, November 19, I observed History of Western Art Music taught by Dr. Valerie W. Goertzen. I arrived early and introduced myself to the professor. Realizing that I am Chinese, Dr. Goertzen told me that in her childhood she studied at a U.S. American primary school in Taiwan.
The professor talked about opera in western art. Opera is an art form in which singers and musicians perform a dramatic work combining text (called a libretto) and a musical score. Opera is part of the western classical music tradition. Opera incorporates many elements of spoken theater, such as acting, scenery, and costumes, and it sometimes includes dance. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble. It is popular in western culture.
I like this class because in my country we did not study music in school. At Loyola, you can study pretty music.
