China's neglect of environmental education has also led to the low environmental awareness of China citizens. Therefore, environmental protection education should be implemented from the time of students, and permeated into the process of cultural education, so that students can realize knowledge reserve and improve social moral quality at the same time. There are many connections between junior high school biology and environmental education, which is conducive to the infiltration of environmental education. Integrating environmental education into subject teaching is conducive to students' understanding and acceptance.

The infiltration of environmental protection education in the process of biology teaching should be based on the teaching content of biology classroom, dig deep into the environmental protection points in biology textbooks and expand them, so that students can understand the importance of environmental protection through independent exploration and practice. Below we mainly discuss how to infiltrate environmental education in junior high school biology classroom teaching.

First, infiltrate environmental education into relevant knowledge points.

Environmental education should be based on the teaching content of biology course and take the teaching content as the key link to realize the connection and expansion of environmental education. For example, when learning about "caring for vegetation and greening the motherland", teachers can tell students about the important role of green vegetation in protecting our living environment, and then connect it with the current wanton felling of green vegetation, which has caused serious environmental pollution and endangered the natural environment on which we depend. Teachers can show students some pictures of areas covered with green vegetation, and then show some pictures of areas where vegetation has been cut down a lot, so that students can feel the important protective effect of green vegetation on environmental health through comparison. Through some shocking videos of environmental pollution caused by vegetation destruction, let students know that if green vegetation is cut down in a large area, human survival will face great threats, thus stimulating students' desire to protect vegetation and awareness of protecting the environment.

Second, the flexible infiltration of environmental education in biology teaching

There are many places in biology textbooks where the concept of environmental protection has been added. Therefore, when teachers tell this part of the content, they can change the original teaching method of allowing students to read freely, attach importance to this part of the content, lead students to study together, and infiltrate environmental education into teachers' stories. For example, when teachers talk about the distribution of roots in soil, they usually don't focus on the content of "planting grass on hillsides to keep water and soil", but just let students remember this measure of keeping water and soil. However, if we want to deepen environmental protection teaching in biology teaching, we should not ignore these knowledge points, but should guide students to explore deeply, tell them about soil erosion, and let students understand that soil erosion is an important ecological problem we are facing at present. After students know the causes of soil erosion, they can tell them the relevant measures to avoid soil erosion, so as to realize the flexible infiltration of environmental education in biology teaching.

Third, pay attention to the inquiry activities of the curriculum.

Many inquiry activities in biology courses are aimed at cultivating students' awareness of environmental protection. Therefore, teachers should attach importance to the inquiry activities of biology courses, let students participate in them, and feel the importance and necessity of environmental protection more truly. For example, when studying the related content of "analyzing the examples of human activities destroying the ecological environment", teachers can let students explore the ecological environment destruction phenomena around them and understand the causes of these environmental destruction phenomena and their harm to people's lives. Through students' independent exploration and independent thinking, we can more intuitively realize the harm caused by environmental damage, and then realize the importance of environmental protection, and implement environmental protection in daily life.

Fourth, the use of social practice to infiltrate environmental education

The infiltration of environmental protection education should not only be linked with the classroom, but also be implemented in life practice, so as to cultivate students' environmental awareness and sense of responsibility, stimulate students' enthusiasm for participating in environmental protection, and enable students to actively implement environmental protection actions in life practice. For example, schools can organize students to carry out tree planting activities on Arbor Day, or let students go to the seaside to pick up garbage and organize waste battery recycling activities, so that students can actively participate. Only by putting environmental protection into concrete actions can students truly understand the significance of environmental protection. Infiltrating environmental protection education in junior high school biology class is a positive response to the current establishment of an eco-environmental society. Combining knowledge teaching with social morality education is conducive to cultivating social talents with both ability and political integrity, and also provides strong support for China's environmental protection cause.
