On October 12, 2022, the third lesson of Tiangong Classroom began. All classes in the school actively watched Tiangong classroom videos under the leadership of the class teacher. The course started with the three astronauts, and the three astronauts took everyone to visit the "new classroom" Wentian Experimental Cabin, showing us the sleeping area of Wentian Experimental Cabin, and the Wentian Experimental Cabin is equipped with four scientific experimental cabinets: scientific glove box and low-temperature storage cabinet, life ecology experiment cabinet, biotechnology experiment cabinet, and change gravity experiment cabinet.
Chen Dong Put three measuring tubes of different thicknesses into the water. Not long after, the water rose to the top of the measuring tube. He asked the students to carefully observe how the surface tension of the fluid is effective. "Without gravity constraints, the surface tension of the fluid will be more obvious, driving the liquid level to rise rapidly." The thinnest straw turns on the "speed double mode". Chen Dong used a small experiment to show the difference in the world of fluid phenomena in the microgravity environment of the space station. He placed three plastic tubes of different thicknesses and placed them in the thinnest tube in the water and quickly reached the top. It seemed that the "speed double mode" was turned on.
A small steel ball makes the water ball "lazy". When Liu Yang uses a syringe to spray air into the water ball, the water ball vibrates violently. After adding a steel ball to the water ball, the impact with the same force will decrease. What's going on?
Through this viewing of the Tiangong Classroom Video Activity, students gained a lot. "Tiangong Classroom" is a heritage, a dream, and a look upward, which contains the infinite potential of China Aerospace to keep moving forward. According to Wang Yaping , after the first space teaching, "many children fell in love with aerospace because of this, and some children applied for the aerospace major because of this. Some children have even become my colleagues now, which is also a place that makes me very proud and proud." The relay dream of "I became you when I grow up" is the unique romance of China's aerospace industry. The foundation of science and technology lies in education, and the success of career depends on continuation. Through space teaching, the space dream and the Chinese dream are spread to the heart, and the knowledge and skills are imprinted into the mind. There will be more Chinese figures and Chinese footprints on the journey of the stars and seas.
