Infiltrating moral education in junior high school chemistry teaching can start from the following aspects:

1. Take patriotism education as the main line to cultivate students' sense of national pride and responsibility. For example, by explaining China's ancient alchemy, the invention of gunpowder and other historical events, students can understand the great wisdom of the Chinese nation and its contribution to world civilization.

2. Pay attention to collectivism education and cultivate students' team spirit and sense of collective honor. For example, students can be organized to carry out group experiments, discussions and other activities to encourage them to help each other and make progress together.

3. Based on scientific spirit education, cultivate students' innovative consciousness and practical ability. For example, we can guide students to pay attention to chemical phenomena around them, encourage them to ask and solve problems, and cultivate their spirit of inquiry and practical ability.

4. With honesty education as the core, cultivate students' moral quality and sense of social responsibility. For example, students can be required to record experimental data honestly, abide by laboratory rules, and cultivate their sense of honesty and social responsibility.

5. With environmental education as a supplement, cultivate students' awareness of ecological civilization and sustainable development. For example, it can explain the influence of chemical reaction on the environment, guide students to pay attention to environmental protection issues, and cultivate their ecological civilization concept and sustainable development consciousness.

In a word, the infiltration of moral education in junior middle school chemistry teaching requires teachers to closely combine the teaching content with students' reality and adopt various ways and methods to comprehensively improve students' moral education quality.
