How to make use of the chemical experiment to improve our ability? Chemical experiment is a basic method and means of chemical research, is the basis of chemical relies for survival and development, but also the soul of the chemical. Through the chemical experiments can not only make us to obtain chemical knowledge, training our practical skills and quality, but also can cultivate our study of theory with practice and the scientific attitude of seeking truth from facts, serious. Can say, do a good job in the chemical experiment teaching is an important means of improving our scientific and cultural quality. How to make use of the chemical experiment to cultivate and improve our scientific literacy? According to my own understanding and the teaching practice in the brief talk about the following:

The First. strengthen our understanding of knowledge, cultivate the our ability of observation and thinking ability

As we know, the experiment process is the process of the textbook theory into practice, the description of the experimental textbooks will be shown in the experimental process, make the knowledge visualization, specific, so as to deepen memory of knowledge and understanding.Different experiments with different experimental phenomena, by observing the experiment phenomenon, the students can actively use the learned knowledge to understand and explain the different phenomena. This will not only greatly stimulate the students interest in learning, and, more importantly, in the process, c an use textbook knowledge actively guide the students to observe and explain the different experimental phenomena of different experiments. Good to cultivate the students’ ability of observation and thinking ability. Also need to supplement some experiments in the process of learning to enhance students' understanding of knowledge, for example, in the interpretation of the metal active order, I added the reaction of sodium and water experiment: to join a small amount of water in the beaker and a few drops phenolphthalein test solution, then add metallic sodium. Let the students know the metallic sodium was observed in the water into a shiny ball, move around on the surface of the water, water solution quickly appear red, etc. The experimental phenomena. These phenomena for experiment and the students' observation, put forward several problems situation of thinking and analysis: sodium from kerosene to remove? Why use a knife to cut? Why the water melting into a shiny balls? Why solution into red? Through the analysis of these problems and explain, sodium in the form of existence in nature, the preservation of the sodium, sodium burning can put out the fire with water and sodium in the copper sulfate solution can copper replacement out and a series of problems are solved. Through the experiment, induce, widen and deepen the students' thought.

The Second, encourage students to improve the experiment, develop students' divergent thinking and innovation consciousness, and cultivate the students' scientific literacy In the chemical experiment in the learning process, as we all know, a lot of improvements of the teaching experiments are needed to improve, in the process of experiment, even all of the things that have become uncertain have to be review from different angles and sides, in order to constantly improve and develop.

Traditional teaching methods for chemistry experiment is mostly "gourd ladle" painting, but failed to give full play to students' subjective initiative, influenced by its long-term students long and spontaneity, lack of independent thinking, hard to create,
