There are many contents related to environmental protection in middle school chemistry textbooks. For example, CO, as the number one killer of air pollutants, has been systematically studied in junior high school textbooks. When teaching this section, explain clearly the generation, characteristics and harm of carbon monoxide to students, and organize students to watch movies and videos about carbon monoxide poisoning and how to deal with it after poisoning according to the actual situation of students and schools. Explain its formation process and its harm to students, so as to improve students' attention to environmental pollution.

2, in the process of chemical experiment, environmental education.

As an important part of chemistry teaching, chemistry experiment also bears the responsibility of environmental education for students, which is more intuitive than classroom teaching. On the one hand, I observed, analyzed and studied environmental pollutants as test samples. For example, through the chemistry extracurricular interest group, I conducted an investigation on environmental pollution activities, and organized students to go to nearby rivers and iron ore dressing plants to observe the sewage discharge and the ph value of sewage and distilled water. On the other hand, when doing or guiding students to do experiments, they can also carry out environmental education on the spot. For example, when detecting the release of toxic gases (such as CO such as SO2), tail gas treatment devices can be added to reduce the emission of toxic gases. After the experiment, the waste liquid and waste should be put into the designated place, which can not only reduce the pollution of pollutants, but also educate students to do their own environmental protection work. Only in this way can we develop good environmental habits.
