The formation and development of chemistry stems from and depends on experiments. Chemical experiment should have the following teaching functions: it is the source of chemical scientific knowledge, an effective way to cultivate scientific methods and the only way to cultivate scientific attitudes. Today, in order to create an efficient classroom and give full play to students' initiative, chemistry teachers should make full use of the unique role of chemistry experiments in chemistry teaching and build an experiment-based learning platform, so that students can give full play to their initiative, show their creativity and gain true knowledge and fun in chemistry experiments.
Second, change the teaching concept and establish the guiding ideology of experimental teaching in innovative education.
The purpose of chemical experiment teaching is not only to verify the principle, let students understand and master the existing book knowledge, but more importantly, to cultivate students' scientific quality, stimulate students' interest in science, and cultivate students' innovative ability and practical ability. Therefore, it is necessary to change the traditional experimental teaching mode of "teachers talk, students listen, teachers demonstrate and students watch". In experimental teaching, teachers are required to prepare teaching materials, teaching methods and students from the students' actual ability. In the teaching process, students' thinking has been in a state of active exploration.
Third, make full use of chemistry interesting experiments to create a happy learning situation and stimulate students' thirst for knowledge.
Interest is the best teacher. Junior high school students are generally curious and mysterious about vivid chemical experiments. Appropriate experiments not only help students understand and master knowledge, but also stimulate students' interest and inspire them to think and explore in a directional way. It can be to introduce new lessons through surprise experiments. This is a quite common experimental guidance method. Make use of students' unexpected strange phenomena, arouse students' attention, arouse students' thinking, thus generating a strong desire for knowledge and guiding them to enter.
