| Every real knowledge comes from practice. The chemistry experiment that acts as a kind of special practice activity, is a foundation on formation and development of chemistry science. It is by teaching on chemistry experiments that may stir up students interest of studying chemistry ;help students understand chemistry concepts; and acquire chemistry knowledge and the technical ability on experiments; and benefit to train students chemistry ability to observe and to do experiments; bring up innovation spirit. Furthermore, that a good rigorous scientific approach will be formed is very important content and path to raise students scientific accomplishment.Firstly, this thesis was based on thoughts and theories of chemistry teaching material experiment parts of establishments that was discussed, and stressed on studying the United States reformation of the high school chemistry teaching material practices since half a century ;and summed up five characteristics on experiment parts of establishments: First has more than hours of the experiment lesson, and student need use half time do the experiment; Second is to emphasize strict and careful science attitude, and educate students as scientists to do the experiment; Third is that a chemistry experiment should face to the society, face to the life and face to the other related course; Fourth is that investigating types and its ability have been used as the important contents on chemistry experiment reform and development; Fifth is that chemistry teaching material establishment emphasize universal science and technique knowledge, and increase citizens chemistry science attainments.Next, we have analyzed reformations on our country high school chemistry teaching material experiment part from choosing the experiment material angle, we have showed several reformation trends: The first, the teaching material increased the student the experiment quantity gradually and relative experiment illustrations; The second, she valued on training student the basic operation ability with experiment and the ability of study experiments; The third, she made a point of contacting the chemistry experiment with social life as well as her nviron-ments; The fourth, she increased the vivid of the chemistry experiment teaching with the interest. At the same time, the writer also analyzedfour problems that teaching material exits: first, A chemistry experiment is placed down and depended on the theory and is in subsidiary position; and is short of expanding the space ; Second, chemistry the experiment arrangements in order changed again and again, lacked complete science theory to guide; Third, there are fewer chemistry experiment; Fourth, there are more verification experiments , fewer investigating experiments.Finally, I discussed three enlightenments that the United States high school chemistry teaching material reform practices benefited to compiling our country high school chemistry teaching material experiment parts rfirst, a government should value the foundation education and the whole society wants to participate together, the chemistry course reforms; second, that the education reform experiences should be valued to raise the theoretical standard so as to guide the plait of the teaching material ;Third chemistry course reformations must have the fresh and clear ages characteristics .Moreover, specific chemistry teaching material especially compiling chemistry experiment parts should be held as follows four aspects: The first, lesson knowledge should be given consideration, and experiments alone be made a book, outstanding to foster experiment ability .The second, the junior high school should keep on with senior high school chemistry teaching material experiment parts; The third, reforming the high school chemistry experiment should contact the society with nearby of life, and stir up the student' s study interest; The fourth, we should value to educate the student investigating ability, and add up students doing experiments.
