Mum: You look so happy, John! Is there anything interesting today?

John: Yes, mum. We had a special lesson at school, today.

Mum: A special lesson?

John: Uh-huh, Chinese astronauts, Zhai Zhigang, Wang Yaping, and Ye Guangfu, taught us a live science lesson in the Tiangong space station, 400 kilometers above Earth.

Mum: Really?

John: They showed us how they lived and worked inside the space station.

Mum: .

John: Yes and no. They also use the microwave and fridge in the space kitchen, which can help them to heat and store food.

Mum: What about the differences?

John: . In a buoyancy experiment(浮力实验), Wang put a table tennis ball in a glass of water. Instead of floating to the surface like on Earth, the ball remained in the middle of the water. Buoyancy almost disappeared in the weightless environment.

Mum: That's amazing! What else?

John: She created a water film (水膜) using a metal ring and a bag filled with water. . The bud blossomed (开花) magically on the film.

Mum: That must be beautiful. You are so lucky. The development in communications technology of China has made it possible to transmit (传输)real-time video from space to the ground.

John: It's so amazing! .

Mum: Go ahead.

[Mum smiles and hopes this lesson can take root in his heart as a seed, and ultimately grow into towering trees.]
