    Lesson A2 - The greenhouse effect: understanding with an analogy

     

    MAIN SUBJECTS

    Natural sciences / Physics

    DURATION

    Preparation: 5-10min

    Activity: 1h15

    AGE GROUP

    9-15 years

    LEARNING OUTCOMES

    Students build a greenhouse model as an analogy to greenhouse gases in the atmosphere.

    They learn that:

    • All objects emit infrared radiation; the warmer they are, the more infrared radiation they emit.

    • When the Earth’s surface is warmed by the sun, it emits infrared radiation.

    • Greenhouse gases act like a blanket, absorbing infrared radiation emitted by the Earth’s surface.

    • Only part of this infrared radiation escapes into space and the rest is sent back to the surface. This explains global warming.

    TEACHING METHOD

    Experimentation, documentary analysis
