In this activity, students create a model of the greenhouse effect to explore how the greenhouse effect operates and contributes to climate change.
Earth's atmosphere acts somewhat like the glass of a greenhouse, which keeps the greenhouse warm by trapping heat. Incoming radiationfromthe Sun is absorbed by the earth's oceans and land, where it is converted into heat, warming the surface of the earth and the air above it. Particular gases in the atmosphere act like the glass of a greenhouse, preventing the heat from escaping.
Greenhouse gases ( GHGs) such as water vapour, methane, and carbon dioxide are naturally found in our atmosphere. Human activities are accelerating the rate at which some carbon-based GHGs are produced. These greenhouse gases contribute to the warming of the atmosphere and to global climate change.
