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.
