On the afternoon of October 12, the third lecture of " Tiangong Classroom " started. Astronauts of the Shenzhou 14 flight crew, Chen Dong, , , Liu Yang, , and , Cai Xuzhe, who are "on business trip" in space, serve as the main lecturer of this class. In the brand new classroom "Ask Tian Experimental Cabin", they introduced their work and life scenes, demonstrated the capillary effect experiments in the microgravity environment, the experiments of water balls becoming "lazy", fun drinking water in space, and the wrench that can turn heads. They also showed the research on rice and Arabidopsis thaliana planting carried out on China Space Station , and carried out glove box plant cutting operations.
, while expanding the boundaries of science and technology, enriching educational experiments, while satisfying children's curiosity, while planting the seeds of aerospace. "There is no gravity in space, why can the roots of rice dive down into the soil?" "How many colors are there in the earth you see in the universe, and which one is the most beautiful?" In the ground classroom, about 400 representatives of primary and secondary school students listened to the explanation through video calls and scrambled to ask questions. Space teachers can not only make scientific principles interesting, but also answer children's fancy questions. For example, when answering the last question of this class, Chen Dong said: "When the earth is shining with the sun, we can see blue oceans, yellow and green land, snowy mountains and large yellow deserts, and floating clouds. The earth without the sun is also very beautiful, and we can see the lights of the city."
"Technology is like a bonfire, we are clustered around." 's classroom located in the vast space is like the bright and vivid color, which arouses the students' infinite imagination. Today is the third lecture of "Tiangong Classroom". In the first two "Tiangong Classrooms", strange phenomena such as beautiful blue planets, cool space turnover, wonderful water and oil blending, and crystalline white "ice hockey" were staged one after another. With unique experimental conditions and passionate Q&A explanations, a large number of young and children watched and learned. , the "highest" classroom for popular science in China, is known as the "online class ceiling" and has been urged by countless netizens to update and like it. Now, space teachers have once again started teaching mode, which not only allows hungry children and netizens to "quench their thirst", but also deepens the public's awareness of the importance of the aerospace industry, especially teenagers. is the highlight of this course. The space teacher invited young people to conduct experiments simultaneously in the world. Through the comparison of "heaven and earth", he cleverly stimulated his students' interest in science, attention to aerospace , and persistence in exploration.

The fascinating classroom content is only 50 minutes, and the actual preparation process is very complicated. It is reported that experts from multiple fields participated in lesson preparation, including experts in aerospace systems, college teachers and researchers, primary and secondary school teachers, etc. Before the "Tiangong Classroom" starts, astronauts must repeatedly test to ensure the experimental results, feedback the test results to the expert group on the ground, and confirm and communicate the content. 's careful lesson preparation and accurate presentation not only reflects the country's emphasis on science education for young people, but also demonstrates the strong scientific research capabilities of China's space station. The golden autumn October is the season of harvest. The display and sharing of aerospace achievements will undoubtedly allow children to gain the nourishment of knowledge from it, feel the prosperity of the country's aerospace industry, and learn from the spirit of Chinese aerospace 1. The spirit of striving for progress and positive.
Su Shi Once asked the sky with wine, Li Bai Once raised his glass to invite the moon. Due to the shortage of technology, ancient poets were full of enthusiasm and could not get a realistic response from the sky. Today, Chinese astronaut relay shows the real experience of stepping into space. It not only realizes the smooth dialogue between heaven and earth, but also turns the place where they work and life into a warm and interesting classroom. This really makes people sigh at the wisdom, persistence and courage of Chinese astronauts to pursue their dreams. I believe that children "walking into" such space classroom can be shocked by it, and they will continue to pursue their dreams, and will spread their wings and fly high to a wider world.
