Lesson B2 - The greenhouse effect: role-playing game
Physical education (<12 years)
Preparation : 5 + 15min
Activity : 1h
In a game of catch, the students understand the role of greenhouse gases in “trapping” infrared radiation and stopping it from “escaping” into space so they can link this phenomenon with global warming.
When heated, all objects emit infrared radiation.
When the Earth’s surface is heated by the sun, it emits infrared radiation.
The greenhouse gases in the Earth’s atmosphere absorb infrared radiation emitted by Earth’s surface: only part of this infrared radiation escapes into space and the rest is sent back to the surface.
An increase in the greenhouse gas concentration results in a temperature increase of the Earth’s atmosphere.
