An Analysis and Improvement of the Line Spectrum Observation on Flame Reaction Experiment in Middle School Science Textbook

摘要

The purpose of this research was to analyze and improve the line spectrum observation on the flame reaction described in middle school textbook.The continuous sample injector and the spectrometer kit observable line spectra were developed to improve the flame reaction experiment.Students could well distinguish the flame color of elements and observe the difference of line spectrum pattern for each element.
