| Abstract |
|
Construction of a handy spectroscope using a compact disk (CD) or a CD-ROM and its application to the observation of emission and absorption spectra are described. Using this simple cardboard-made spectroscope, one can readily observe line emission spectra of fluorescent lamps, gas discharge tubes, etc. The spectroscope is also used to observe the absorption spectra of colored solutions; the absorption bands are observed as distinct black bands on the rainbow-colored continuous spectrum of an incandescent lamp. The results for the aqueous solution of potassium permanganate, the methanol and ethanol solutions of cobalt chloride, and Fe(III)-thiocyanate complex are described. These results clearly show the general rule that a colored solution absorbs the complementary color of the color of the solution. Thus, the CD-ROM spectroscope is a useful tool in primary and secondary schools to teach what color is and what spectra are. Furthermore, it can be used effectively in introductory courses in colleges and universities to teach that spectra are really beautiful natural phenomena which can be observed simply.

| Chemistry Teacher Connection |
|
The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
|
| C&EN CLICs |
|
Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students.
