In order to vigorously promote the spirit of science, popularize scientific knowledge, disseminate scientific ideas, and cultivate students' awareness of love for science and the spirit of advocating science, on April 25, Linyi Demonstration Primary School specially invited Dr. Yang Haihua, a scientist from the Chinese Academy of Sciences and an expert in the field of microbiology and biotechnology, to give a wonderful lecture entitled "The Story of Human-friendly Microorganisms" to more than 100 teachers and students in the fifth grade. In order to express their warm welcome and high respect for Dr. Yang, the representatives of the Young Pioneers presented flowers to Dr. Yang and wore red scarves.
"Students, do you know what microorganisms are, and what microorganisms do you know?" Dr. Yang asked everyone some questions about microorganisms, and everyone looked at each other with curious expressions on their faces. With these questions in mind, Dr. Yang led everyone on a wonderful journey about microbes. Dr. Yang talked about the three types of bacteria, fungi and viruses in microorganisms. She used humorous language and professional knowledge to introduce a series of microorganisms and their uses, such as Escherichia coli, lactic acid bacteria, yeast, mold, Aspergillus oryzae, Penicillium, etc. At the same time, combined with examples from daily life, students can understand that microorganisms are good and bad, and they are also friends and foesThe students listened attentively and with great interest.
At the end of the lecture, she interacted with the students, which made the atmosphere very lively. The children's bold guesses, positive responses, and professional questions were all affirmed by Professor Yang. Professor Yang Haihua presented prizes to 5 outstanding students, and Ma Zihao, a student from Class 5 (6), was the most outstanding, and Professor Yang awarded him the emblem of the Chinese Academy of Sciences as a token of encouragement. The students enthusiastically took a group photo with Professor Yang and met at the Chinese Academy of Sciences.
Through this popular science lecture activity, students have a deeper understanding of the relationship between microorganisms and human beings, and scientific thinking and comprehensive literacy have been further cultivated and improved. I believe that the students' interest and enthusiasm in understanding and exploring nature will become stronger and stronger, the concept of science and technology will take root in their hearts, and the seeds of science and dreams will surely blossom in their hearts!
