Introduction to the biology interest group in middle school
The middle school biology interest group was a group that allowed students to explore biological knowledge and carry out a variety of biology-related practical activities in their spare time. In different schools, biology interest groups carried out all kinds of activities. Some biology interest groups would conduct plant-related practices, such as cutting roses. Students would collect rose branches, learn how to handle the cutting, understand the joints of the plant and its role in cutting, and soak the cutting branches in water before cutting them into a foam box and sealing it to keep it moist. Some of them would conduct cell model making activities. Under the guidance of the teacher, they would use ultra-light clay to build cell prototype and restore the internal structure of the cell. After the production was completed, they would record the process by making a PowerPoint. This would help students combine theory with practice and experience the magic of the biological world. Some of them would conduct insect specimen making activities. In the biology laboratory, students could carefully study butterfly and other insect specimens. In this process, they could cultivate a love for insects and nature. There were also biological interest groups that carried out traditional Chinese medicine planting activities. Teachers would first explain the biology and pharmaceutical knowledge of plants, as well as the use of tools and communication etiquette. Then, they would lead the students to sow traditional Chinese medicine seeds such as platycorum grandiflorum and perilla according to the requirements. There were also biological exploration groups that explored the structure and flowering period of apricot flowers, bringing knowledge out of the classroom through observation and experience. The activities of these biology interest groups not only allowed students to gain theoretical knowledge of biology, but also allowed them to experience the charm of biology through practical operations and stimulate their interest in biology.
