On paper, it is shallow.
I don't know how to do it.
This special experiment is being collected.
Excellent works submitted by Xinong students.
Fully embodies one sentence:
Wisdom is not just in knowledge
It also exists in the ability to apply knowledge
Discover the mysteries of molecules!
Creative experiments with unique perspectives.
Let us feel the power and beauty of science.
Drosophila salivary gland chromosomes
Huan Wang - School of Life Sciences
This is the chromosome of the salivary glands of Drosophila that I photographed in a genetics lab class, and it looks like a small person walking leisurely, and I thought it was interesting when I saw it. Although this is not a standard Drosophila salivary gland chromosome, I saved it anyway.
I think the charm of biology experiments is that people can gain knowledge and explore the unknown at the same time.
Localization of proteins
Yanting Zhang - School of Life Sciences
Recently, I did a localization experiment of an unreported protein, preliminarily** it is localized on the cytoplasmic membrane, which is Merge in one piece**, and the results found that the protein is localized in the cytoplasmic membrane, and is also expressed in the cytoplasm and stomata, it should be very meaningful to do further experiments!
Plant cross-section
Zhou Xiang - College of Horticulture
Have you ever seen a "bird" in the microcosm of plants? Have you ever seen a "butterfly" in a plant? If you haven't seen it, you'll be amazed at the wonders of plants.
The cotton leaves are cut cross-sectionally, and the whole looks like a bird with wings spread, but there are various plant structures such as spongy tissue, epidermis, xylem, and phloem.
The lily anther cross-cutting, which looks like a dancing butterfly, shoulders the mission of lily reproduction, and is composed of plant structures such as fiber layers, vascular bundles, and pollen grains.
Laser confocal microscopy
Jiannan Huang - School of Life Sciences
The first experiment with laser confocal microscopy was recorded, which simply consisted of transfecting a plasmid with green fluorescent GFP into cells and infecting a lentivirus with red fluorescence (RFP) at the same time, which was observed under a 100x oil microscope**.
The three images, from left to right and from top to bottom, are brightfield, green fluorescence, and red fluorescence. The observation process was really full of problems, but fortunately, I saw a different fluorescence, although the results did not meet our expectations, but fortunately, I am in a good state of mind, and I hope to continue to work hard and continue to work hard!
Experience the charm of physics!
Try it one at a time.
Design your own creations.
Logic circuit diagram
Zhichen Lv - School of Information Engineering
There are five steps to design this experiment: the first step is to draw the original state diagram, and then list the original state table; The second step is to simplify the original state table; The third step is to code the state according to the adjacent coding method; The fourth step lists the Carnot diagrams of d1, d2 and output z, and then derives the expressions for d1, d2 and output z; Finally, a logical circuit diagram is drawn according to the expression.
By designing the circuit yourself, you have a deeper knowledge and understanding of serial sequence signal detectors, and at the same time, you have a better grasp of the application of flip-flops.
Listen to the secret words of plants!
In the ocean of exploration science.
Every experiment is a fantastic adventure.
Planting rape seedlings
Hao Yang - School of Life Sciences
The most impressive experimental experience is to plant rapeseed seedlings in Fengxian County, Shaanxi Province at the end of last year, and the tutor selected the location in an abandoned lead-zinc mining area in the mountainous area of Fengxian County. We set off from Yangling and passed through5 hours drive and half hour climb(The last road was steep and dangerous, and the car couldn't drive in), and finally came to the lot.
We first borrowed a weeding machine and a bulldozer from a local farmer to tidy up the fields and remove large stones, which was not an easy job to be honest, and then we planted signs with our mentors and disciples to sow seeds. Our practice in this one thoughIt's very different from the usual laboratory seedlings, but this is the one time in recent years that I feel the closest to the earth and nature
Unlock the code to food!
Chinese cuisine is broad and profound.
But we always come up with new ideas.
Make more innovations.
Making dumplings
Ye Sun - College of Resources and Environment
The purpose of this experiment was to learn and practice the skills of making dumplings according to a specific recipe, so as to improve the taste and nutritional value of dumplings.
Through this experiment, I learned the technique of making dumplings according to a specific recipe and improved my hands-on ability. In your daily life, you can try different flavors of dumpling fillings to enrich your food experience, and at the same time, you can try to use a variety of vegetables, proteins and other healthy ingredients as fillings to improve the nutritional value of dumplings. In addition, pay attention to hygiene during the production process and keep the kitchen clean and tidy to ensure food safety.
Flexible chromosomes and cross-sections.
Did it spark your desire to experiment?
Complex and orderly routes.
Does it challenge you?
This experiment award showcased the students of Xinong.
Scientific research spirit and innovation ability
Through continuous exploration and practice.
We will continue to contribute to the modernization of our agriculture.
