Starting from May 27, the Expo will broadcast 10 "Shanghai Education Live Broadcast", inviting the Shanghai Municipal Education Commission, Shanghai Science and Technology Museum and the heads of district education bureaus to jointly discuss how to do a good job in science education addition in education "double reduction", explore a new paradigm for training top-notch innovative talents,
and lead the new connotation of high-quality education development with science education. And education has helped Shanghai accelerate the construction of a science and technology innovation center with global influence and other new achievements in practical education.
This "big live broadcast" especially highlights the form of "dialogue", on the one hand, each "big live broadcast" invites the heads of the two district education bureaus to have regional dialogue;
On the other hand, representatives of primary and secondary school teachers and students from the two regions will also be arranged to engage in interactive dialogue with live guests as live viewers.Chinese scientists reveal 100,000-year history of rice evolution
Rice is one of the three staple foods in the world. When and where did humans first start to grow rice, eat rice, and develop rice agriculture?
On May 25, the cover news reporter learned from the Chinese Academy of Sciences that the research team of Lu Houyuan, a researcher at the Institute of Geology and Geophysics of the Chinese Academy of Sciences,
cooperated with experts from 13 units such as the Zhejiang Provincial Institute of Cultural Relics and Archaeology to jointly carry out research on the origin of rice at multiple sites of the Shangshan culture, revealing a continuous evolution history of rice from wild to domesticated for 100,000 years.
According to reports, the study further confirmed that China is the origin of rice in the world, and the Shangshan culture, about 10,000 years ago, has an important position in the origin of world agriculture. The relevant paper was published online in the international academic journal Science in the early morning of May 24, Beijing time.
The Shangshan site was discovered in November 2000, and the Shangshan culture was named in November 2006. At present, 24 sites of Shangshan culture have been discovered, which are all located in Zhejiang. They constitute the largest and most concentrated group of early Neolithic sites known in China and even in East Asia.
The research shows that as early as 100,000 years ago, wild rice was already distributed in the lower reaches of the Yangtze River, providing conditions for the utilization and domestication of rice by the ancestors.
About 24,000 years ago, the climate entered a cold ice age, which allowed humans to explore new food sources, and began to collect and use wild rice. About 13,000 years ago, humans began to cultivate wild rice, intentionally or not. About 11,000 years ago, domesticated rice appeared on the "historical stage", and rice agriculture originated in East Asia.
Experts point out that this is an important milestone in the history of human development, and it can be said that the time of the origin of rice agriculture and wheat agriculture in the West Asian Mesopotamia origin is synchronized.
According to reports, Chinese scientists have made a series of major discoveries by establishing scientific standards to effectively distinguish wild rice from domesticated rice, using multidisciplinary research methods and combining field archaeology.The "Future Scientists" science popularization activity was held in Ning
On May 25, during the National Science and Technology Week, Jiangsu Agricultural Society and Nanjing Science and Technology Association jointly launched a science popularization activity of "Future scientists" in Jiangsu Academy of Agricultural Sciences, aiming to stimulate young people's enthusiasm for science and guide them into the world of agronomy.
The activity is divided into four sections. First of all, the children became little entomologists and visited the only butterfly ecological park in the Yangtze River Delta region, witnessing the transformation of butterflies and feeling the miracle of life.
Then, turning into little botanists, they strolled through the plant resource bank of the Jiangsu Academy of Agricultural Sciences, exploring a wide variety of rhododendrons and enjoying the magic of nature.
Later, the children became little germplasm scientists, and in the germplasm resources laboratory, they learned the secrets of seeds, how to identify seed vitality, and how to select high-quality seeds, and developed a strong interest in biodiversity.
Finally, they embarked on a journey of exploration and visited the central laboratory of Jiangsu Academy of Agricultural Sciences to explore the daily work of scientific researchers.
In addition to scanning electron microscopy, there are high-end instruments such as liquid mass spectrometer for food safety detection and electronic tongue for evaluating food sensory quality (taste).
This activity not only gave the children an in-depth understanding of agricultural knowledge, but also stimulated their love and exploration of science.In line with The Times of early childhood science education, what?
On May 24, the third STEAM Science and Technology Festival of Kindergarten of Guangdong Academy of Sciences was launched. In order to stimulate children's interest and ability to explore science, and play the trinity of education functions of kindergarten and institute community,
this science and technology festival is divided into two links: the opening ceremony and science and technology experience project, reflecting the scientific atmosphere everywhere, and fully demonstrating the concept of "science education from the baby".
