The students gathered data on the various spectra on a diverse selection of light sources: Excited gas tubes and different kinds of light bulbs. They were asked to draw the spectral lines correlating to each source to show the relationship between the number, arrangement and excitement level of the electrons.
A wonderful example of the different elements' spectra is located here. Java is required to see the demonstrations.
Students are asked to extrapolate from their readings and class materials to successfully answer the questions on the back of their data sheets; these answers are to be turned in tomorrow, 7 October 2008.
