Week of 10/19/09

This week was one of the best weeks of school. In chemistry, we did a lab with flames on Wednesday. We put a metal loop into different solutions of chloride and burned it in a flame. There were many different-colored flames. My favorite colored flame was a pinkish purple flame. It burned for a long time. Some other flames did not burn as long. This lab was one of the funnest lab. After we burned the specific flames, we got six other mystery solutions. We had to guess which solution we thought the flame would be from. Yesterday, I saw some glow in the dark thing after the light went through the filters. I learned about the electromagnetic spectrum. I learned that there were different wave properties like the frequency, wavelength, and energy. All lights had the same speed. The infrared light video was very cool. Night vision was interesting. We also finished the Einstein video.

This week was overall not as stressful. For chemistry, we watched more of the movie. I liked this movie. It was great on how the movie taught us all of the history behind each part of the equation. I thought Albert Einstein had an odd mind because he could connect energy with mass and the speed of light. I did not like how Einstein left his first wife and married his cousin. He was not loyal and only cared about his fame. I think marrying your cousin is diagusting. In class, we also did a lot of practice on alpha and beta radiation equations. I discovered that I always made many careless mistakes on these equations. I need to be more careful when I fill in the equation. I also learned about using C-14 to find out how old something is. I found this pretty interesting.
