Received May 24 th 2012; revised June 30 th, 2012; accepted July 10 th, 2012 Here we present the significance, content, results, and teaching effect ofa selective self-design experi-ment —a simple test for measuring the emission spectra of artificial light sources, and discuss its function and potential problems in an environmental chemistry class for undergraduate students. Also, we propose several ways to reform experimental teaching, and provide references to other experimental courses. Keywords : Self-Design Experiment; Spectrophotometer; Spectrum; High Pressure Mercury Lamp; Deuterium Lamp Introduction Laboratory courses are a ponent ofa National Quality Course (NQC) — Environmental Chemistry. In this re-search group, we believe that the construction and reform of this subject is important, and our core task is to develop teach-ing quality, improve students ’ experimental abilities, promote motivation and enthusiasm, inspire a spirit of scientific
