Tiangong Classroom Lesson 2

On the afternoon of March 23rd, the China Manned Space Engineering Office, in collaboration with the China Association for Science and Technology, the Ministry of Education, the Ministry of Science and Technology, and the Central Radio and Television Administration, jointly launched the second space lecture on "Tiangong Classroom", which was broadcasted globally by the Central Radio and Television Administration. Three Shenzhou 13 astronauts, Zhai Zhigang, Wang Yaping, and Ye Guangfu, collaborated to complete the second lesson of "Tiangong Classroom".

The second lesson of the "Tiangong Classroom" continues to adopt a dialogue between heaven and earth. Astronauts will demonstrate the space "ice and snow" experiment, liquid bridge demonstration experiment, water oil separation experiment, and space parabolic experiment in orbit, introducing and showcasing space science facilities, inspiring the enthusiasm of young people to continuously pursue the "science dream" and achieve the "space dream".

The editor spent some time compiling a collection of the second space lecture on the Chinese space station. Let's learn together and experience the fun of science!

The 2022 Winter Olympics and Paralympics were successfully held in China. The first experiment of the "Tiangong Classroom" was related to "ice and snow". In the experiment, cotton thread with crystal nuclei was used to contact supersaturated sodium acetate solution to form a "hot ball" resembling a "ice ball". Let's take a look at the space "ice and snow" experiment together.

The second experiment in the second lesson of "Tiangong Classroom" - Liquid Bridge Demonstration Experiment, in which two plastic plates are connected using the surface tension of water.

After the experiment, the astronaut teacher left a question: What are the ways to build a longer liquid bridge?

The third experiment in the second lesson of "Tiangong Classroom" - Water Oil Separation Experiment.

In the experiment, the astronaut teacher and the students on the ground shook the bottles containing water, oil, and liquid respectively to compare the phenomena of the heaven and earth experiment.

After shaking the water and oil liquids on the ground, there was a noticeable layering, while the water and oil liquids did not layer after the space station shook. Then, through interaction with classmates, the astronaut teacher used an "artificial centrifuge" to achieve layering of water and oil liquids in the space station.

The fourth experiment of the second lesson of "Tiangong Classroom" - Space Parabolic Experiment

The new generation of top stream, Bing Dwen Dwen, has also met everyone at the space station. What will happen when Bing Dwen Dwen is thrown out of the space station?

Let's follow the astronaut teacher to understand what motion an object thrown in a weightless environment will make?

Astronauts use practical teaching and the exciting "Heavenly Palace" experiment leaves a deep impression on students! Behind the experiment lies a wealth of subject knowledge, waiting for students to discover and explore.

In the second lesson of "Tiangong Classroom", three astronaut teachers not only brought interesting and magical scientific experiments, but also introduced some of the facilities in the space laboratory to the students

How does the suspension experimental platform return to its original position after deviation? What is the secret behind container free experimental material cabinets? Why does "re glow" phenomenon occur in zirconium metal melting and solidification experiments?

Let's walk into the "Heavenly Palace Classroom" together!

Astronauts give space lectures during busy missions, reflecting the country's emphasis on popular science education. Space teaching further stimulates students' love for science and their longing for space, actively exploring the unknown world.

Technology is full of fun and charm, and for teenagers, interest is the best teacher. Only by fully mobilizing their interests can they become more determined in their pursuit and longing for technology from the bottom of their hearts.

The "Tiangong Classroom" has made science more deeply ingrained in people's hearts and redefined science popularization courses, showcasing China's confidence in science and technology, and allowing the flower of science popularization to bloom.
