I will try it too, remember to tell your students what I said

1. Sound phenomenon: the sound-absorbing wall of the World Expo Cultural Center

2. Light Phenomenon Expo Axis and the British Pavilion, these two buildings are excellent examples of light phenomena

3. Thermal Phenomenon The temperature in the Expo area is 3 to 5 degrees lower than that in the urban area. A big reason is the use of "low pressure" "Two-phase flow spray cooler"

4. For mechanics, please refer to the mechanics principles of the Saudi Pavilion and China Pavilion

5. Physical properties

6. Electricity LED balloons at the opening ceremony of the World Expo, neon lights in the exhibition hall at night

7. Simple mechanical Expo tickets, tools for processing tickets when you enter the park

8. Energy low-pressure two-phase flow How does a spray cooler cool down?

9. Energy-saving and environmentally friendly greening on the roofs and walls of each exhibition hall

10. Let’s talk about the light rail and tram at the World Expo

I know them very well That’s the answer
