In the 1980s, microscope chemical experiment originated in the U.S. It is an internationally recognized to reflect the "green chemistry" concept experiment with new technologies and new chemical methods. It is known as chemical experiment revolution. With the economic sense and environmental awareness, the constant infiltration of green chemistry concept, people are constantly required for experimental changes in the hope to find a test not only save funds, reduce environmental pollution, and do not affect results technology and methods in this context, microscope chemical experiment, as a new technology, new methods produced. Although our country started later, but the prospects is very optimistic, and also to obtain the corresponding results.The author in this article focused on the current high school chemistry experiment analysis of miniaturization, because the experimental approach in secondary schools can no longer keep up with a new round of reform of foundation courses, are not well reflect the "student-oriented "purposes. This paper from the following aspects of microscope chemical experiment described: the meaning of microscope chemical experiment, the development process of microscope chemical experiment at home and abroad. Selected and analysis articles from 1994 to 2008 of the "Chemistry Education" magazine about microscope chemical experiment in the secondary school. And collated from the experiments summarized the development of microscope chemical experiment point of view and the type of experimental design. And on this basis, selected two typical Organic Chemistry experiment of secondary school as the starting point, designed by its micro-chemical experiment, compared conventional experiments with microscope chemical experiment about the phenomenon, comparison of data, etc. It can thus be seen that compared to conventional experimental test for advantages and disadvantages. Finally, obtained the note and principles in the miniaturization of conventional experiment. And analysis of the relationship of micro scale chemical experiment and conventional experiment, that they are complementary, and should avoid weaknesses and glorified.
