"You can smell it, do you have any special smell in its rhizomes, can you guess what kind of plant this is?" The teacher's voice has not fallen, and a bunch of white flowers have begun to pass on the curious classmates who pass on the hands of the students who pass over. Essence For a while, some people frowned, some people's eyes were shining, and some people made a ghostly face like smelling "shocking" smell.

This is the scene in the "Campus Plant Recognition and Specification" class, "Campus Plants and Specifications", which was jointly established by Huang Aijun, Huang Aijun and Jiang Jinhuo, School of Life Sciences, Zhejiang University. In this course, students from different colleges and majors gathered because of a similar curiosity. Everyone put down the textbooks, left the classroom, and followed the teacher to the corner of the campus to find the vigorous vitality in the summer.

"So so" sigh

It turned out that this plant with a special smell seen by the classmates is called "ravioli", which is commonly known as folding ears and Houttuynia cordata. After introducing its roots, stems, leaves, flowers, fruits and other botanical knowledge, Jiang Jinhuo began to talk about some "small secrets of plant" that we are usually not easy to understand.

"In Yunnanchuan area, people will add chili, garlic, salt, vinegar and other seasonings to mix Houttuynia cordata and eat it. Its special odor can also bring some effects of dampness and insect repellent." Ah, drinking its stems and leaves to drink is also a folk recipe for clearing heat and detoxifying. "

The class happened to be a classmate from the Yunnan -Guizhou area. They nodded again and again, and shared it with the classmates around them. Most of the students in other areas were the first time to see Houttuynia cordata, and their faces were full of question marks. After listening to the teacher's explanation, they sighed "the original".

In addition to Houttuynia crooquet, the students' observation logs also include the fragrance and high -standing Guangyulan. The golden yellow flower seems to be the golden silk peaches flying in the bushes in the bushes. … Follow the teacher to stop, and you can easily bring the red flowers, green grass and branches of the half -campus to the bottom of the eyes, remember it, and hide in the heart.

Wang Xiaofeng, an undergraduate student of Zhu Kezhen College, said: "After a short semester course, I started to pay attention to the different shape characteristics of the branches and leaves from the" plant 'that I had described before. ","

After taking this course, students can be transformed into "small experts of plant knowledge", and to classmates and friends around the classmates on campus plant knowledge: camphor trees are not only common sidewalk trees, but also can emit unique aromas; roadside on the roadside; roadside on the roadside; Although the purple leaves are fruitful, it is not suitable for eating because of the dust caused by driving ...

"Nature" classroom

In addition to knowing plants on campus, teachers will also teach how to dissect flowers and seeds in the classroom, and the flowers of the original flowers can also be expressed with flower -like rationality. Live like a big fat man, and the grains of rapeseed are small and smooth. Students need to be eye -catching and concentrated to find out the structure of the microscope of the vision.

Not only is the classroom content unique, but even the final assessment method is novel and interesting. Students need to use the knowledge learned in the classroom, and make two plant specimens. After the steps of collection, suppression, plastic surgery, drying, and paper paper, they will permanently treasure their favorite four seasons.

If you want to use plants to depict cute and playful small animals, or to record the scenery you see, and even the mood in poetry and songs, it is better to come to the laboratory to make a unique plant sticker!

Student works -plant stickers

One cut, one swing, and sticky, each step needs to play twelve points to ensure that the final presentation works integrate poetic and aesthetics. This process is both creation and enjoyment. Students always lament the passage of time when they look up, and the so -called "happy time is always short." Teachers will also choose excellent works to integrate desk calendars for commemorative.

What exactly does this course become a "explosive" general class that students compete for? The educational concept that naturally integrates theoretical knowledge and life practice is inseparable.

Seeking Wang Xiangguang, an undergraduate student at Yunfeng Academy in the College: "This course made me originally do not understand that I only know that it is a tree or a grass or a grass. The systemic knowledge of the system also has the fun of practicing it by itself, which has benefited well. "

In this course, the students followed the teacher to stop and stop on the campus. They relaxed their moods in strolls and released pressure in the green color. The mysteries under the eye -catching appearance.

Huang Aijun said: "Nature is a classroom, and it is natural to see it." It is true that nature not only teaches us the vigorousness of our lives, but also teaches the beauty of beauty. Just like Jiang Jinhuo said: "Naturally beautiful, the plants are beautiful, let us discover this beauty." Through the course, let the students walk through the campus, perceive the migration of the four seasons and the growth of all things, integrate science, life and beauty, and positive. It was the original intention of this lesson.
