化学是以实验为基础的科学,化学实验是化学学科研究的主要方法,是化学的基础。学生在做实验前教师一定要先让学生掌握化学概念,这对学生实验的准确性起着至关重要的作用。化学本身理论性的东西就比较多,教师应该让学生通过实验来对书本上的理论做进一步的验证,这样更容易使学生理解抽象的化学理论知识。一、激发学生对化学实验的兴趣例如,在讲解二氧化碳气体的收集时,教师可以以一个有趣
Chemistry is based on experimental science, chemical experiments are the main method of chemical research, is the basis of chemistry. Before a student can do the experiment, the teacher must first let the students grasp the concept of chemistry, which plays an important role in the accuracy of the students’ experiments. Chemistry itself is more theoretical things, teachers should let students through experiments to further verify the theory of the book, it is easier for students to understand the abstract knowledge of chemical theory. First, to stimulate students interest in chemical experiments For example, in explaining the collection of carbon dioxide gas, the teacher can be a fun
